Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A medical device comprising: a polymeric region comprising an elastomeric block copolymer that comprises a poly(p-hydroxystyrene)-polyisobutylene-(p-hydroxystyrene) triblock copolymer; and a therapeutic agent disposed within or beneath the polymeric region; wherein the medical device releases the therapeutic agent upon implantation or insertion into a subject and exhibits a sustained release profile with more than 50% of total release of the therap…
