1 1.1 Distinguish between the terms degradable and bioactive as used to describe biomaterials.

2 1.2 Discuss the materials design characteristics required for intravascular stents and how the design of the intravascular stent has evolved over the last few decades.

3 1.3 Discuss the materials design and selection issues for the femoral stem of an artificial hip joint.

4 1.4 Bearing couples in artificial hip joints are composed of (i) a metal ball articulating against a polyethylene liner (metal‐on‐polyethylene) or (ii) a ceramic ball articulating against a ceramic liner (ceramic‐on‐ceramic). Compare the engineering and biological issues related to the use of these two bearing couples.

5 1.5 Describe the major ways in which the so‐called contemporary biomaterials differ from those previously used.
