Abstract

A dual-layer dilatation balloon includes an inner layer that includes a polymer selected from the group consisting of a polyester, polyether, polyamide and copolymers thereof, and an outer layer that includes a polyamide. The dual-layer balloon optionally further includes a stent disposed on the balloon. The stent is optionally a drug-eluting stent. A process for forming a dual-layer dilatation balloon includes forming a dual-layer extrudate having an outer layer that includes a polyamide and an inner layer that includes a polymer selected from the group consisting of a polyester, polyether, polyamide and copolymers thereof. The process also includes forming the dual-layer balloon from the dual-layer extrudate in a balloon forming machine, wherein the balloon has a hoop strength of about 10,000 to about 60,000 p.s.i.
