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 a styrene monomer and an isobutylene monomer. Moreover, the styrene monomer content of the copolymer typically ranges from 25 to 50 mol %.
