- What?
- A biomaterial is a nonviable material
used in a medical device, intended to
interact with biological system
- Key: "Biocompatibility" - Ability of a material to perform
with an appropriate host response in a specific application.
- Eg; Resistance to blood clot, bacterial
colonization and uncomplicated healing
- -Intimate contact with host / living tissue
- Does not cause any adverse effects on host
tissues or organs
- Eg; Resistance to blood clot, bacterial
colonization and uncomplicated healing
- Key: "Biocompatibility" - Ability of a material to perform
with an appropriate host response in a specific application.
