Abstract: Multilayer balloon for a catheter comprises 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 multilayer balloon for a catheter and a balloon catheter are also provided.
