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.
