Abstract:
In embodiments, a stent includes a copolymer having a modulus of about 10 MPa or less and exhibiting hydrolytic degradation substantially by surface erosion. For example, the copolymer can include elastic segments formed of trimethyl carbonate polymer or copolymer, and rigid segments formed of a lactide, glycolide, ε-caprolactone polymer or copolymer.
