STUDY QUESTIONS for Lectures 1 and 2: BIOLOGICAL CONSTRAINTS in USING BIOMATERIALS- Following the lectures the student should be able to answer the following statements and/or questions: 1. Define a medical device. Describe 4 classes of medical devices and give an example of each, describe an additional way that materials are classified. 2. Define biocompatibility, pathology, etiology, pathogenesis, pathologic findings. 3. Describe how the body responds to a biomaterial implant. 4. Explain how biomaterials are evaluated following explantation. 5. What are gross morphological findings? Microscopic findings? 6. Given a piece of liver tissue how do you process it to get a glass slide? 7. What does an H & E test tell you? Name at least three other stains and what they are used to detect. 8.
