Abstract
Balloon catheter comprises an elongate catheter shaft having a proximal section, a distal section, and an inflation lumen defined therein and a multilayer balloon on the distal section of the shaft comprising a first layer made of a first polymer material having a first Shore durometer hardness, a second layer made of a second polymer material having a second Shore durometer hardness greater than the first Shore durometer hardness, wherein the second layer is an inner layer relative to the first layer, and a third layer made of a third polymer material having a third Shore durometer hardness less the first Shore durometer hardness, wherein the third layer is an inner layer relative to the second layer. Method of making a balloon catheter is also provided.
