CATHETHER FLEXIBLE DISTAL TIP |
摘要 |
The catheter (5) with a flexible tip (20) includes a manifold (25) at the proximal end, a flexible catheter body (40) having a proximal end and a distal end, a balloon (15) at the distal end and a distal flexible tip (20). The catheter is designed for operation as an "over the wire" catheter and would be compatible with a flexible guidewire, such as guidewire (30). The flexible tip invention also would be compatible with "rapid exchange" or "single operator exchange" catheters. Flexible tip (20) extends distally from balloon (15) and guidewire shaft (55). In the preferred embodiment flexible tip (20) is formed from distal material of balloon (15). The length of the flexible tip (20) will vary depending on the path that catheter (5) must travel through the artery to get to its desired location. The length of the tip will balance the pushability desired versus the flexibility desired. A longer flexible tip (20) on catheter (5) would allow enough flexibility a the tip for catheter (5) to get at hard to reach lesions through at tortuous path. A shorter flexible tip (20) on catheter (5) would make the tip stiffer and allow higher pushability through blocked arteries. By varying the flexible tip (20), the catheter (5) may be designed for many different conditions.
