Abstract
Balloon catheter comprises an elongate catheter shaft having a proximal section, a distal section, and an inflation lumen, and a multilayer balloon on the distal section of the shaft. The multilayer balloon 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 lower than the first shore durometer hardness, wherein the second layer is an inner layer relative to the first layer, and an outer-most layer made of a third polymer material having a third Shore durometer hardness lower than the second Shore durometer hardness.
