Abstract
An encapsulation for an implantable medical device is provided defined by a blend of high molecular weight polyisobutylene and low molecular weight polyisobutylene solution to provide desirable stretchability and elastic properties without sacrificing water resistance properties of the encapsulation. The encapsulation material is flexible thus allowing the medical device to possess tissue matching flexibility and retain long-term normal function free from liquid infiltration.
