Abstract
A medical device has a structure made of a first biodegradable and/or bioabsorbable material and a second biodegradable and/or bioabsorbable material encapsulating a degradation additive incorporated into the first biodegradable and/or bioabsorbable material. The second biodegradable and/or bioabsorbable material has a degradation rate that is faster than the degradation rate of the first biodegradable and/or bioabsorbable material such that the structure experiences a period of accelerated degradation upon release of the degradation additive following sufficient degradation of the second biodegradable and/or bioabsorbable material.
