Abstract
A medical balloon for a balloon catheter is described. The balloon has at least a first layer made from a first material and a second layer made from a second material, said first and second layers being in overlying relationship with one another and being integral with one another; wherein the first layer has a softening or melting temperature which is higher than a softening or melting temperature of the second layer. A method of forming the medical balloon is also described, including locating a raw tubing in a mold; preheating and inflating the raw tubing so as to cause it to stretch; heating the raw tubing to soften or melt the second layer; setting the inflated raw tubing to form the medical balloon; and cooling the set balloon.
