摘要： A catheter balloon and method involves extruded tubing with multiple layers of different durometer values, selected such that the blow up ratio (BUR) at the balloon's inner surface is increased. In one method a two stage blow mold process uses a small radius initial stage where radial growth is limited, followed by a second stage to a final dimension. A single stage blow mold process is also disclosed where the materials and processing are selected to approach the elongation to failure limit of the material. The single stage approach is preferably followed by a modified post-expansion heat set treatment to promote greater axial strength, leading to a preferred failure mode in the axial rather than radial direction.

摘要： Multilayer balloon for a catheter comprising 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 is made of a second polymer material having a second maximum blow-up-ratio greater than the first maximum blow-up-ratio. 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. 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.

The inner sleeve has a relaxed configuration with an inner diameter greater than the outer diameter of the noninflated balloon, and a collapsed configuration with an inner diameter less than the relaxed inner diameter. The outer sleeve is slidably positioned on at least a portion of the inner sleeve and has a tapered first section with an inner diameter tapering towards a nontapered second section, the nontapered second section having a substantially uniform inner diameter less than an outer diameter of the relaxed inner sleeve and configured to hold the inner sleeve in the collapsed configuration.
