Abstract: Multilayer balloon for a catheter comprises a first layer of a first elastomeric polymeric material, and a second layer of a second elastomeric polymeric material having a lower maximum blow up ratio (BUR) than the first elastomeric polymeric material and being an outer layer relative to the first layer. The multilayer balloon is formed by blow-molding such that the multilayer balloon is blown, in at least a first stage, to a final working radial dimension, wherein an area draw-down ratio (ADDR) of 2.0 for the multilayer balloon is targeted.

Abstract: Method of making a balloon catheter includes providing an elongated shaft having a proximal end and a distal end and an inflation lumen extending therein, providing a multilayer tube, forming a multilayer balloon by blow-molding the multilayer tube such that the multilayer balloon is blown, in at least a first stage, to a final working radial dimension, and securing the multilayer balloon on a distal section of the shaft with an interior of the multilayer balloon in fluid communication with the inflation lumen. The ADDR of the multilayer balloon after formation is approximately 2.0.
