Control Applications of Heart Assist Devices: Yih-Choung Yu (Lafayette College), Marwan A. Simaan (University of Pittsburgh)
As heart disease remains a considerable health problem around the world, the development of both equipment and methodologies for its treatment are of great interest and priority. While the heart transplant is the most widely accepted method for dealing with severe cases of the disease, demand for these transplants exceeds the supply available. Thus, ventricular assist devices (VADs) are being developed as alternatives. Indeed, as the reliability and performance of VADs improves, they are becoming increasingly viable for long-term implants in addition to their traditional role as a bridge to native heart transplantation. There are other encouraging signs for the future of VADs – recently several successful rehabilitations of patients using VADs have been reported, implying that the use of such devices is not limited to long-term implantation or as bridge-to-transplant, but also as bridge-to-recovery.

Description:

Relevance of the Session

The importance of interaction between industry and academia is of extreme importance in any engineering disciplines.  This point has been emphasized in ACCs in recent years, and industrial tracks have been introduced to promote the participation of engineers and researchers from the industrial sector and to let academic researchers become aware of industrial problems relevant to the control community.  Industry-academic interaction at conferences is a welcoming trend, but the interaction between industry and academia should take place on more daily basis.  This session will be a forum to discuss and present various forms of industry-academic interactions including programs at the National Science Foundation to promote such interactions.  Practice in other leading industrial countries will be discussed also.

 Format

The session will begin by a series of presentations by panelists.  As described below, this part will be extremely informative to session attendees although scientific contents will be minimal.  Because of this nature, the panelists will not be asked to prepare written papers.  The session will also have a discussion and general question-answer period.  This session is of interest to all participants, and the organizer requests that it be treated as a special session.

 Panelists

Panelist 1: Professor Masayoshi Tomizuka (University of California, Berkeley)

Some opening remarks will be given by Professor Tomizuka, the organizer of this special session.  Remarks will include the overview of various forms interactions between industry and academia and some fundamental issues to be resolved when industry groups participate in research at academic institutions. Such issues include handling of intellectual properties (IP), and publication of research papers. 

Panelist 2: Dr. Jeannie Sullivan Falcon (National Instrument)

National Instruments (NI) sees many benefits to collaboration with universities in both research and teaching.  NI offers various “pioneer” programs that provide cutting-edge software and hardware technology prior to actual product release.  NI also provides a limited number of research grants to professors for work that will complement our product offering or that will apply NI technology to an innovative application.  NI also hosts the Embedded Engineering and Control Design Summit at NIWeek to bring together university professors and industry researchers from around the world.  In the area of education, NI offers an Equipment Grant program, described on ni.com/academic, for university classes and teaching laboratories with a special focus on Dynamic Systems and Controls.

Panelist 3: Dr. Matthew White (Hitachi Global Storage Technologies, San Jose, CA)

Dr. White will present a case of the Computer Mechanics Laboratory (CML), an industrial consortium at the University of California, Berkeley.  Dr. White was a PhD student supported by CML, and now supports it as a representative of Hitachi Global Storage Technologies (HGST), an industrial consortium member.  His presentation will start off with a short description of CML (organization, motivation, history, operational challenges, ...), then move on to experiences as a student, and close with the benefits for the industrial members (wide range of technical expertise, ability to support high-risk, long-range products, recruiting for future employees, ...).  

 Panelist 4:  Dr. Mario Rotea (Program Director, Control Systems Program, Intelligent Civil and Mechanical Systems Cluster, National Science Foundation)

Dr. Rotea will present programs at NSF relevant to the ACC community with emphasis on industry-academic interactions.  All NSF proposals are now evaluated by applying two criteria:  intellectual merit and broader impacts.  Broader impacts include education, dissemination of research findings, technology transfer to industry, and so on.  While each proposal does not touch every point of broader impacts listed in the NSF proposal guide, the close interaction of academic researchers with industrial partners is strongly encouraged.  Dr. Rotea will also present the Grant Opportunities for Academic Liaison with Industry (GOALI), a co-funding mechanism at NSF to promote industry-academic interactions.

Panelist 5:  Dr. Martin Krucinski (Xerox Corporation)

Xerox is one of a few leading companies which have a foundation to promote research at academic institutions.  Xerox has also established partnerships with several academic institutions including participation in academic research as a GOALI partner on several projects.  Dr. Krucinski's PhD dissertation work was supported by a GOALI project awarded to the University of California at Berkeley (UCB) with Xerox as the industry partner.   He now participates in another GOALI project with UCB as an industrial co-principal investigator (PI).  Dr. Krucinski will share his GOALI experience with session attendees from the viewpoints of an academic researcher and an industrial co-PI.

Panelist 6:  Dr. Andrzej Banaszuk (United Technologies Research Center)

We will advocate the need to change the role of dynamics and control community from fixing problems related to the detrimental dynamics using active control to the design for beneficial dynamics early in the design cycle. The talk will summarize lessons learned in industrial research on mitigation of flow and structure oscillations in jet engines (thermoacoustic instabilities and turbomachinery flutter). Attempts to introduce control late in the design process and without proper attention to control architecture often fail because of high cost to modify the design to add on active control. We will also show how certain aspects of design (symmetry) contribute to the origin of detrimental oscillations and point out how the dynamical systems and control theory methods can guide the design to prevent the oscillations. The control and dynamics methods used early in design allow one to manipulate the physical feedback loops in the system to create beneficial dynamics and exploit design flexibility at low cost. To increase impact of experts in control and dynamics on the design process, the experts need to establish credibility in the technical community that owns the design process. In industrial environment this can be accomplished by playing a key role in a response to a crisis, and following up with teaching of basic principles of dynamics and control to the design community and their management.

Panelist 7:  Dr. Maarten Steinbuch (Eindhoven University of Technology, The Netherlands)

Within the Netherlands, a major concentration of high tech industries (electronics, medical devices, mechatronics, automotive) in located in the south east, making the triangle Eindhoven (NL), Leuven (B) and Aachen (D). A major recent development is the installation of research institutes where academic researcher from industry and academia are collaborating. This includes the Embedded Systems Institute, The Holst Centre for Smart Electronics, the Competence Centre for Automotive Research and the Molecular Medicine centre. Some of the problems and challenges of these centers will be discussed.

Description:

A. Introduction and Objective:

In April 2005, the University of Minnesota (UMN) Libraries sponsored a special interdisciplinary conference on Publication, the Public University, and the Public Interest: What's the future of scholarly publication? [1]. This conference was part of the UMN President's 21st Century Interdisciplinary Conference Series. It focused on exploring key issues facing scholarly publications and examining how the academy is changing because of them. The following is taken from the conference brochure and website:

About the UMN Conference Scholarship means little without publication. But the definitions of "publication" are undergoing major changes. The digital age has brought unprecedented opportunities to share research discoveries with a global audience, prompting a revolution some have compared to post-Gutenberg times. Yet as the Internet and World Wide Web have unleashed new resources and capabilities, they have also challenged the conventions of how research is published and shared- Traditional modes of publishing-print journals and books-have served scholars for decades. Today, though, scholars in some disciplines advocate making research results available through free electronic archives, and some are even suggesting that universities and funding agencies require n open access" publishing. Other new publishing genres like blogs have also been embraced by scholars. Featuring presentations by leading thinkers from the scholarly community, this conference explores:

. Current challenges in scholarly communication and publication

. The ways in which research is shared and exchanged

. The role of the public university in sharing the products of research  Alternative publication systems, including open access publishing

. Recent movements to legislate free access to the products of research . The changing landscape of copyright and intellectual property

These issues are as prevalent today in the Control System Society as they for the entire academy. Few of our publications challenge the traditional modes of publishing, with perhaps the only one that comes to mind is the online journal, AIAA Journal of Aerospace Computing, InfO1'mation, and Communication (AIAA JAGIC). The editor of AIAA JACIG, Lyle Long, notes in his January 2005 status editorial "...the reluctance of authors to take advantage of the multimedia nature of JACIC [2J." He goes on to state that the journal "... needs to become more of an online community website." The future for scholarly publications will be one of dramatic change. The proposed session will help facilitate discussion regarding that change and what direction the controls community should take.

The main objective of this session to inform attendees ~bout the status of scholarly communication in the academy and to discuss the exact issues posed at the Spring 2005 UMN Publication, the Public University, and the Public Interest conference within the context of the controls community.

B. Structure

The proposed session will consist of one overview paper and a panel discussion with editors of many of the top controls journals. The first presentation is entitled Publication, the Public University, and the Public Interest will be authored by Wendy Pradt Lougee, University Librarian at the University of Minnesota. This presentation will provide an overview of the current status of scholarly publications and the issues facing the research community. Ms. Lougee was the driving force between the Spring 2005 UMN conference on scholarly publications and has been active in the area for the last 10 years.

Following the main presentation, a panel discussion will be held with editors of some of the leading controls journals to discuss the issues raised and to plan action for the future. The editors who have agree to participate at this time include:

• Prof. Frank Doyle, Editor-in-Chief, IEEE Transactions of Control System Technology

• Prof. Dennis Bernstein, Editor-in-Chief, IEEE Control Systems Magazine

• Prof. Christos Cassandras, Editor-in-Chief, IEEE Transactions on Automatic Control

• Prof. R. Russell Rhinehart, Editor-in-Chief of ISA Transactions - the Journal of Measurement and Control for the Instrument, Systems, and Automation Society.

• Prof. Suhada Jayasuriya, Editor-in-Chief, ASME Journal of Dynamic Systems, Measurements and Control

• Prof. Lyle Long, Editor-in-Chief, AIAA Journal of Aerospace Computing, Information, and Communication 

• Prof. Ian Craig, Editor-in-Chief, IFAC Control Engineering Practice

Editors of other control system journals will be contacted and invited to participate.

C. Conclusions

This session presents a unique opportunity to engage the controls community in the issues facing scholar publications today. This issue is timely and a service to the community. Attendees will be able to participate in the discussion and offer opinions and advise regarding the future of our community. We believe this session would be an excellent addition to the 2000 ACC and we hope the reviewers will agree.

0. [10 MINUTES]: B. Ogunnaike: Introduction and Overview of Biological Control Systems

Followed by 3 papers. (25 minutes each)

1.        Francis J. Doyle III: Control  Insights for both analysis and synthesis in Medicine

Systems biology has emerged as a major interdisciplinary research area that links such classical fields as biology, chemistry, and engineering. Each of these fields brings a unique set of tools to solve the problems in this emergent discipline. In this talk, the quantitative tools from systems theory will be presented as an enabling methodology for solving bioengineering problems.

Much of our work is motivated by the observation that the human body is a complex chemical factory, composed of many highly interactive multivariable subsystems. It has also been demonstrated that natural “controllers” achieve tight regulation of these systems under a variety of conditions in order to meet stringent performance requirements - thus achieving robust performance. There is a clear opportunity to bring analysis methods from control theory to provide understanding for the situations when these controllers are effective, as well as when they fail. Our work in this area has focused on the gene regulatory architecture that underlies circadian rhythm. The rich multi-scale robust behavior exhibited by this network will be described.

In parallel, we have also studied quantitative approaches to therapeutic methods for biomedical problems. In particular, we will focus in this talk on the problem of diabetes. The complications of diabetes are thought to arise from poor control of blood glucose concentration because of inadequate secretion of insulin by the pancreas. This has motivated the undertaking of novel engineering approaches to the controlled delivery of insulin. In this talk a closed-loop feedback system is discussed which responds to changes in blood glucose concentration, based upon a glucose sensor, and permits adjustment of the rate of insulin release provided by a pump. Control challenges that are addressed include asymmetric performance specifications, hierarchical objectives, and run-to-run behavior.

2.        Stefan Streif, Eric Bullinger, Rolf Findeisen, Frank Allgöwer: Controllability, Observability and Sensitivity Analysis in Biological Systems

Biological reaction networks are often very complex and contain many uncertain parameters. Sensitivity analysis plays an important role in understanding and analyzing the influence of the parameters on the system behavior. This paper aims at deriving connections between classical systems theory concepts, such as controllability and observability, and sensitivity analysis such as metabolic control analysis, common in systems biology. Specifically we show a connection between the cross-Gramian, which is closely related to observability and controllability Gramians, and the response coefficients of metabolic control analysis. The implications of these results are illustrated with a biological reaction network example.

3.        B. Wayne Bequette: Sensors and algorithms for continuous glucose monitoring and control

An individual with Type 1 diabetes has lost the ability to produce insulin and must receive daily injections, or continuous infusions, of insulin. Diabetics must closely monitor their blood glucose levels by pricking their fingers several times each day to obtain blood glucose values from glucose test meters. Intensive insulin therapy, with frequent (painful) blood glucose measurements and insulin adjustments, has been shown to lead to better blood glucose regulation and reduce long-term complications from Type 1 diabetes that are due to hyperglycemia (high blood glucose). The primary negative aspect to intensive insulin therapy has been an increased risk of hypoglycemia (low blood glucose); this can be quite dangerous if an individual is driving a car, for example. An obvious long-term goal is to combine a continuous glucose sensor with an insulin infusion pump (actuator) to form a closed-loop artificial pancreas.

The state of the insulin infusion pump technology is quite advanced, with a large market and many years of successful user experience. The state of continuous glucose monitoring, on the other hand, is much less advanced than pump technology. Existing continuous glucose monitors, and those in late stages of development, have a number of limitations that we will discuss in this talk. The sensors measure the subcutaneous (interstitial fluid) glucose concentration, which generally lags the blood glucose concentration. Also, the sensor signals can have significant measurement noise, along with degradation of the signal with time. In addition, the sensors are calibrated based on capillary blood measurements that can have a level of uncertainty that is not currently explicitly considered in the calibration procedure. This talk will provide an overview of the state of glucose sensor technology, with a focus on the potential impact of estimation theory.

There will be a 5 minute period for discussions at the end.

Control Applications of Heart Assist Devices: Yih-Choung Yu (Lafayette College), Marwan A. Simaan (University of Pittsburgh) (back to Interactive Sessions) (back to top)

Description:

As heart disease remains a considerable health problem around the world, the development of both equipment and methodologies for its treatment are of great interest and priority. While the heart transplant is the most widely accepted method for dealing with severe cases of the disease, demand for these transplants exceeds the supply available. Thus, ventricular assist devices (VADs) are being developed as alternatives. Indeed, as the reliability and performance of VADs improves, they are becoming increasingly viable for long-term implants in addition to their traditional role as a bridge to native heart transplantation. There are other encouraging signs for the future of VADs – recently several successful rehabilitations of patients using VADs have been reported, implying that the use of such devices is not limited to long-term implantation or as bridge-to-transplant, but also as bridge-to-recovery.

Automatic control has received significant attention in the second-generation VAD development. Unlike the existing VADs in clinical use, which consist of a blood sac and valves and operate like a beating heart, the new VADs operate in continuous rotational motion. These devices are smaller in size with better efficiency and no valve. However, the rotational VADs have the ability to develop a negative inlet pressure, which can cause ventricular and atrial collapse, and thus damage the myocardium, blood cells, and pulmonary circulation. On the other hand, an  inadequate pump speed will result in reducing blood pressure and flow, thus, under perfusion of the vital organs. Moreover, as the waiting period for available heart transplant gets longer, the new device must take the  patient’s quality of life into account. The device should require less technical and medical personnel with better diagnostic capabilities of the patient and the device. As a result, an automatic control system that can adjust the operation of the assist devices based on the patient’s cardiovascular demand, without invasive monitoring, would clearly allow the patient greater freedom of activity. This will be a necessity for the next generation of VADs.

There will be five papers in this proposed interactive session. Computer simulation, slide shows, and/or posters will be used for demonstration. There will be a twenty minute open discussion after paper presentation, which provides the audience an opportunity to directly interact with the presenters. Various control applications in VAD development are presented, which include modeling and identification of cardiovascular models for VAD controller development, physiologic controller design for optimal pump speed regulation, minimally invasive estimation of hemodynamic variables, as well as fault detection algorithms for VAD operation monitoring. The devices presented in the session provide a broad coverage of rotary VADs from different perspectives: (1) the types of the devices, and (2) the durations of their intended usage. These five papers include both types of rotary blood pumps: axial-flow pump and centrifugal pump. The durations of their intended usage range from several months (as medium term devices) to more than 5 years (as long term or even permanent devices). Data presented in this session, including computer simulation, animal experiments, and clinical studies, represent the typical resource of data used for VAD controller test and evaluation,. This broad coverage in a session would provide an unusual opportunity for people in control societies to explore how control applications have been involved in VAD development.

Several institutions have been contributed VAD control papers in ACC and CDC conferences over the last few years in regular biomedical application sessions. An interactive session in this particular field would not only provide a great opportunity for colleagues who work in this area to share their experiences but also motivate other control scholars to bring in new ideas for future improvements.
