    摘要： A balloon catheter is disclosed which allows easier fusion-bonding between an inner tube shaft and an outer tube shaft and in which the inner tube shaft can be prevented from being warped when the inner tube shaft passes through a stenosed site, and a method of manufacturing such a balloon catheter. The balloon catheter includes an inner tube shaft having a first layer and a second layer located on an inner surface side of the first layer. The outer tube shaft is fusion-bonded to the first layer and recessed toward the inner tube shaft side. The first layer is formed of a material having higher optical absorption property than the outer tube shaft and the second layer. The second layer is formed of a material having a melting point higher than that of the first layer.

    摘要： A multi-layered balloon is provided where each layer is formed such that each layer is made from tubing that optimizes the inner wall stretch thus providing maximum balloon strength. The high pressure, multi-layer balloon is provided with layers that allow for slipping, such that the balloon has a very high pressure rating and toughness, yet excellent folding characteristics. Methods for producing such multi-layer balloons using existing balloon forming equipment are also provided. The multi-layer balloons can have alternating structural and lubricating layers, or layers with low-friction surfaces. The multi-layer balloons are preferably manufactured using a variety of methods including nesting, co-extrusion, or a combination of nesting and co-extrusion. The multi-layer balloons have balloon layers having substantially similar, or the same, high degree of biaxial orientation of their polymer molecules such that each balloon layer of the multi-layer balloon will fail at approximately the same applied pressure.

    摘要： A catheter has a shaft that defines a delivery lumen, for example, to deliver an elongate medical device therethrough; a proximal section of the catheter includes a seal zone portion, a handle portion and a proximal port portion. A relatively thin wall section of the proximal port portion extends between the seal zone portion and a proximal edge that defines part of a perimeter of a proximal opening of the delivery lumen. The handle portion projects laterally from the seal zone portion, generally opposite the relatively thin wall section. An inflation subassembly of the catheter includes a compliant sleeve member and an inflation lumen extending from the sleeve member, proximally along the shaft, and into a connector port formed in the handle portion. The inflation lumen may be formed by fusing a section of a tube to the shaft and molding the handle portion around another section of the tube.
