Abstract
A medical device has a structure made of a first biodegradable and/or bioabsorbable material and a second biodegradable and/or bioabsorbable material. The first biodegradable and/or bioabsorbable material has a degradation rate that is faster than a degradation rate of the second biodegradable and/or bioabsorbable material. And, the structure experiences a period of accelerated degradation upon exposure of the first biodegradable and/or bioabsorbable material.
