    • A catheter is disclosed providing a balloon catheter having a distal tip that is flexible while additionally incorporating high column strength. The present invention additionally provides a distal tip region that accommodates for various sized guidewires. In preferred embodiments, the distal tip region is initially configured for accommodating the passage of 0.12-inch guidewires only. Through specific manufacturing processes, however, the distal tip is modified so that it also may be expanded to accommodate the passage of 0.14-inch guidewires. In additional preferred embodiments, an elastomeric sleeve is disposed over the modified distal tip to allow the tip to return to the initial 0.12 -inch accommodating profile when the larger 0.14-inch guidewire is withdrawn from the catheter.
    • 公开了一种导管,其提供具有柔性的远侧末端的气囊导管,同时还具有高柱强度。 本发明另外提供一种可容纳各种大小的导丝的远侧尖端区域。 在优选实施例中,远端尖端区域最初被构造成仅容纳0.12英寸导线的通道。 然而,通过特定的制造过程,远侧末端被修改,使得其也可以被扩张以适应0.14英寸导丝的通过。 在另外的优选实施例中,当更大的0.14英寸导丝从导管中取出时,弹性体套筒设置在修改的远侧末端上方,以允许尖端返回到初始的0.12英寸容纳轮廓。
