CHE elective-Spring 2021 course

CHE 59700: Medical Devices: Development and Clinical Application (Spring 2021)
 
A. Instructor: William Clark, M.D.
 
B. Course Description. This course provides a unique perspective to the medical device field, with emphasis on the ways in which chemical engineering processes provide the foundation for many device-related therapies. The course involves the application of several fundamental chemical engineering principles, including those related to mass transfer, separations, and fluid flow, to devices used for extracorporeal therapies and other treatments. The first part of the course addresses the relevant physiology and pathophysiology serving as a foundation for subsequent clinical material. With the focus on extracorporeal devices, the interactions between blood and biomaterials in a general sense are also explored. The second part of the course assesses the extracorporeal treatment of kidney failure by dialysis, which is highlighted as the only long-term, device-based replacement therapy for terminal organ failure (end-stage renal disease). This analysis will not only consider the evolution of dialysis therapy from a technology perspective but also the forces that have shaped its development into a market generating annual revenue of nearly $100 billion on a global basis. The third segment of the course addresses industry-focused concepts pertaining to medical device development, including verification/validation, lean manufacturing, project management, and regulatory issues. Providing a real-world perspective based on 15 years of experience in the medical device field, Ms. Michelle Chutka (Director of Product Engineering, Cook Biotech, Inc; Continuing Lecturer, Davidson School of Chemical Engineering, Purdue University) will lead this third part of the course.
 
C. Prerequisites. CHE 37700 (or equivalent) and BIOL 23000 (or BCHM 30700). These are not strict requirements - interested students should contact Dr. Clark with inquiries.

E. Course Learning Outcomes
  • Assess the mechanisms of blood-surface interactions defining the biocompatibility of an extracorporeal device
  • Evaluate the influence of extracorporeal membrane structure and material on transport properties (diffusion, convection, and ultrafiltration) and the overall effect on device
  • Analyze device-related and patient-related (physiologic) parameters required for kinetic modeling of different dialysis therapies
  • Apply fundamental chemical engineering principles to provide a quantitative basis for treatments of specific clinical disorders, including end-stage renal disease (ESRD), acute kidney injury (AKI), sepsis, cardiac failure, and respiratory failure
  • Characterize the major components of a medical device company and the manner in which these different functions interact during the pre-market and post-market phases of product development
  • Apply important principles of project management, verification/validation, and lean manufacturing to medical device development
F. Course Meeting Schedule (for Spring 2021 semester)
Lectures: TBD
Presentation 1: TBD
Presentation 2: TBD
Final Report due: TBD
 
At the approximate mid-point of the semester, students will assemble into groups of four and choose a medical device-based clinical therapy to study. Each group will provide two progress updates (Presentations 1 and 2) during the course of the semester in lieu of formal examinations. A complete written summary of each group’s assessment (Final Report) will be due at semester’s end in lieu of a final examination.
 
G. Instructor Contact Information.
Professor William R. Clark – Email: clarkw@purdue.edu, Telephone: (765) 496-8647 (office); (317) 691-1438 (cell); office: FRNY 2158
Office Hours: TBD
 
H. Assessment of Course Outcomes. A weighted average grade will be calculated as follows.
Homework (2): 10% each = 20% total
Presentations: 20% each = 40% total
Final report: 40%
 
The grading scale will be as follows.
A: 100 – 85% of the weighted points
B: 84.9 – 75% of the weighted points
C: 74.9 – 65% of the weighted points
D: 64.9 – 55% of the weighted points
F: Less than 55% of the weighted points
 
Note that students with grades within 3 weighted percentage points of either the upper or lower bounds of a grade range listed above will receive a “plus” or “minus” mark, respectively, after his/her score (e.g., scores between 75% and 78% of the total weighted points would earn an B–). Marks of an A– will not be given.
 
Group projects
Student groups may assess a medical device-based therapy from a suggested list prepared by Professor Clark or choose one on their own. In either case, each group should plan to meet with Professor Clark before beginning work on the project to set expectations. The assessment will include the disease state(s) for which the technology is used, its historical development and evolution, the engineering principles underlying its use, the clinical challenges associated with the device, and potentially improved designs for the future. Requirements for the presentations during the semester and the final written summary will be provided early in the semester.
