Patent number: 8703260Abstract: 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.Type: GrantFiled: September 14, 2010Date of Patent: April 22, 2014Assignee: Abbott Cardiovascular Systems Inc.Inventors: John A. Simpson, Sarah A. Nelson, Jonathan P. Durcan

Patent number: 8535596Abstract: Method of making a multilayer balloon for a catheter having a nominal working diameter comprises forming a tube having at least a first layer and a second layer having a combined wall thickness. The first layer is made of a first polymer material having a first maximum blow-up-ratio and 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 method also comprises forming the multilayer balloon from the tube in a balloon mold having an inner diameter corresponding to the balloon's nominal working diameter. The at least first and second layers of the multilayer balloon 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.Type: GrantFiled: February 15, 2012Date of Patent: September 17, 2013Assignee: Abbott Cardiovascular Systems, Inc.Inventor: Jonathan P.
