Abstract
Method of making a multilayer balloon for a catheter having a nominal working diameter comprises forming a tube having at least a first layer and a second layer having a combined wall thickness. The first layer is made of a first polymer material having a first maximum blow-up-ratio and the second layer is made of a second polymer material having a second maximum blow-up-ratio greater than the first maximum blow-up-ratio. The second layer is an inner layer relative to the first layer. The method also comprises forming the multilayer balloon from the tube in a balloon mold having an inner diameter corresponding to the balloon's nominal working diameter. The at least first and second layers of the multilayer balloon define a compliance less than that of a single layer balloon made of the first polymer material with a wall thickness equal to the combined wall thickness.
