Abstract
Multilayer balloon for a catheter includes at least a first layer, a second layer, and a third layer having a combined wall thickness. The first layer is made of a first polymer material having a first maximum blow-up-ratio. The second layer made of a second polymer material having a second maximum blow-up-ratio greater than the first maximum blow-up-ratio, and the second layer is an inner layer relative to the first layer. The third layer is made of a third polymer material having a third maximum blow-up-ratio greater than the second maximum blow-up-ratio, and the third layer is an inner layer relative to the second layer. The at least first, second, and third layers 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. Method of making of multilayer balloon is also provided.
