The two-layer dilatation balloon includes an inner layer containing a polymer selected from the group consisting of polyester, polyether, polyamide, and various copolymers thereof, and an outer layer containing polyamide. The bilayer balloon may optionally further comprise a stent disposed on the balloon. The stent may optionally be a drug eluting stent. A method for forming a two-layer dilatation balloon includes an outer layer containing polyamide and an inner layer containing a polymer selected from the group consisting of polyester, polyether, polyamide, and various copolymers thereof. Forming a two-layer extrudate having: The method also includes the step of forming a two-layer balloon from the two-layer extrudate in a balloon forming device, wherein the formed balloon has a hoop strength of from about 68947.6 kPa to about 41385.4 kPa (from about 10,000 psi to about 10,000 psi). 60,000 psi).
