Abstract
Medical devices such as catheter balloons, stent covers and vascular grafts formed of ultrahigh molecular weight polyethylene. The devices are formed from polyethylene that has been processed so that it is microporous and has an oriented node and fibril structure. The balloons expand compliantly at low strains and are substantially less compliant at higher strains. The invention also comprises methods for making such balloons, including the steps of compacting a polyethylene powder and deforming it to impart the oriented structure.
