Lecture 25 - Biomedical Engineers and Artificial Organs

This video was recorded at BENG 100 - Frontiers of Biomedical Engineering. In this final lecture, Professor Saltzman talks about artificial organs, with a stress on synthetic biomaterials. First, the body's responses (immunological and scar healing responses) to foreign materials are introduced. This leads to discussion of different types of polymer/plastic materials (i.e., Dacron and GORE-TEX) and their properties. Next, Professor Saltzman talks about the design and function of some artificial organs, such as lens implants, heart valves and vessels, hip, dialyzer, heart/lung bypass machine, and the artificial heart. Lastly, challenges and areas for improvement in the field are presented. Reading assignment: Biomedical Engineering: Bridging Medicine and Technology, in preparation by Mark Saltzman (forthcoming by Cambridge University Press); chapters 17 and 18 Resources: Summary and Key Concepts: Chapter 17[PDF]
