摘要： A balloon catheter, and preferably to a rapid exchange type balloon catheter, having a proximal shaft section, and a distal shaft section with an inner tubular member and an outer tubular member, the outer tubular member having a section which is bonded as by fusing or otherwise bonding. The bonded section extends along a thickened wall portion of the outer tubular member at the rapid exchange junction. A reinforcing member or tube extends within at least a section of the bonded section of the outer tubular member. In one embodiment, the reinforcing tube extends within at least a section of the thickened wall portion of the outer tubular member. The configuration provides a rapid exchange junction with improved kink resistance and flexibility for excellent trackability, and with a minimal decrease in the size of the inflation lumen at the rapid exchange junction for an improved shortened balloon inflation/deflation time.

摘要： The invention is directed to a catheter formed at least in part of a multilayered member having a first layer which is fusion bondable to another catheter component such as the skirt of an inflatable balloon and a second layer which is adjacent the first layer having a melting point greater than the first layer so that the multilayered member of the catheter is not deformed when the other catheter component is fusion bonded to the first layer of the multilayered member. The second layer is preferably lubricious in nature. In one embodiment of the invention, the multilayered member is a tubular element with the lubricious second layer defining an inner lumen extending within the tubular element. The outer layer of the tubular member may extend beyond the distal end of the inner layer and form a non-traumatic distal tip. Alternatively, a flexible non-traumatic distal tip may be fusion bonded to at least the outer layer of the multilayered tubular member.
摘要翻译：本发明涉及至少部分形成有多层构件的导管，该多层构件具有可与另一导管构件（例如可充气气囊的裙部）熔合的第一层，第二层与第一层相邻，第二层具有熔点大于第一层，使得当另一导管部件熔合到多层构件的第一层时，导管的多层构件不变形。第二层本质上优选是光滑的。在本发明的一个实施例中，多层构件是管状元件，其中光滑的第二层限定在管状元件内延伸的内腔。管状构件的外层可以延伸超过内层的远端并形成非外伤的远端。或者，柔性非创伤性远侧末端可以熔合结合到多层管状构件的至少外层。
