Abstract
According to an aspect of the present invention, implantable or insertable medical devices are provided, which contain one or more polymeric regions. These polymeric regions, in turn, contain one or more polymers, at least one of which is a copolymer that includes the following: (a) one or more unsaturated hydrocarbon monomer species and (b) one or more heteroatom-containing monomer species.
Claims8
A medical device comprising:
- (A) a polymeric region, said polymeric region comprising an elastomeric block copolymer that comprises a poly(p-acetoxystyrene)-polyisobutylene-(p-acetoxystyrene) triblock copolymer;
- and
- (B) a therapeutic agent disposed within or beneath said polymeric region;
- wherein said medical device releases said therapeutic agent upon implantation or insertion into a subject and exhibits a sustained release profile with more than 50% of the total release of the therapeutic agent from the medical device occurring subsequent to 1 day of administration, said medical device being adapted for implantation or insertion into a subject's body.
