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。

摘要： An apparatus and method for providing a co-extruded, tapered multi-layer shaft. A co-extruded, tapered multi-layer shaft may be fabricated by selecting a first material for the inner layer of the shaft and a second material for the outer layer of the shaft. The first and second materials are then co-extruded by a co-extrusion system including a puller with programmable tapering capabilities. The system forms a hollow tubing having an inner layer and an outer layer, wherein the tubing has the desired tapered characteristics. The result is a tapered tubular shaft having an inner layer and an outer layer.

摘要： A method of forming a thin-walled polymeric tubular member for an intralumenal device, and the member produced thereby. The thin-walled tubular member extruded using the method of the invention is suitable for use a sleeve for a catheter shaft or balloon. The thin-walled tubular member has a single wall thickness of not greater than about 0.003 inch (0.0076 cm). In the method of the invention, the thin-walled tubular member is formed by co-extruding a thin-walled first polymer layer with a removable second polymer layer, and the two layers are separated by dissolution or physical removal of the second layer, to leave the first layer, with the first polymer layer forming the thin-walled tubular member. Because the method of the invention involves co-extruding a removable second polymer layer along with the thin-walled first polymer layer, conventional tooling dimensions in the extruder may be used.
摘要翻译：一种形成用于腔内装置的薄壁聚合物管状构件的方法，以及由此制造的构件。使用本发明的方法挤出的薄壁管状构件适用于用于导管轴或气囊的套筒。薄壁管状构件具有不大于约0.003英寸（0.0076cm）的单一壁厚。在本发明的方法中，通过将薄壁第一聚合物层与可移除的第二聚合物层共挤出而形成薄壁管状构件，并且通过溶解或物理除去第二层来分离两层，至离开第一层，第一聚合物层形成薄壁管状构件。因为本发明的方法涉及将可移除的第二聚合物层与薄壁第一聚合物层一起共挤出，所以可以使用挤出机中的常规工具尺寸。
