Abstract

An intravascular balloon catheter (10) having an ultra soft tip. The catheter includes a braided reinforcement member (70) extending substantially the length of the elongate shaft (60). A balloon (50) is disposed at the distal end of the elongate shaft. An ultra soft tip is formed from a distal portion of balloon material extending distal of the distal end of the elongate shaft.

2. The catheter of claim 1, wherein the proximal end of the distal extension is adjacent the distal end of the reinforcement member.
3. The catheter of claim 1, wherein the portion of the distal waist section extending distal of the distal end of the distal extension forms a distal tip.
4. The catheter of claim 3, wherein the distal tip is an ultra soft tip.
5. The catheter of claim 4, wherein the ultra soft tip has a durometer hardness of between about 5A to about 40A.
6. The catheter of claim 1, wherein the elongate shaft further comprises an inner layer disposed within at least a portion of the reinforcement member.
7. The catheter of claim 6, wherein the inner layer has a proximal end and a distal end, the distal end of the inner layer disposed proximal of the distal end of the distal extension.
8. The catheter of claim 6, wherein the inner layer includes a polytetrafluoroethylene (PTFE).
9. The catheter of claim 1, wherein the outer layer includes a thermoplastic polyester elastomer.
10. The catheter of claim 9, wherein the thermoplastic polyester elastomer is HYTREL.
11. The catheter of claim 1, wherein the distal extension includes a low-density polyethylene (LDPE).
12. The catheter of claim 1, wherein the inflatable member includes a thermoplastic rubber elastomer.
13. The catheter of claim 12, wherein the thermoplastic rubber elastomer is CHRONOPRENE.
14. The catheter of claim 1, wherein the reinforcement member is a braided member.
15. The catheter of claim 1, wherein the reinforcement member is a micromachined hypotube.
16. A catheter comprising:
an elongate shaft including a braided member having a proximal end, a distal end and a lumen extending therethrough, an outer layer disposed about at least a portion of the braided member, the outer layer having a distal end extending distal of the braided member, an inner layer disposed in at least a portion of the lumen of the braided member, the inner layer having a distal end disposed proximal of the distal end of the outer layer, and an inflatable member having a proximal waist section and a distal waist section, the inflatable member disposed about a distal portion of the elongate shaft, the distal waist section having a portion extending distal of the distal end of the outer layer, wherein the distally extending portion of the distal waist section forms a distal tip.
17. The catheter of claim 16, wherein the outer layer includes a first section having a proximal end and a distal end and a second section having a proximal end and a distal end, wherein the first section includes a first material and the second section includes a second material.
18. The catheter of claim 17, wherein the proximal end of the second section and the distal end of the first section form an interface.
19. The catheter of claim 18, wherein the distal waist section is disposed distal of the interface.
20. The catheter of claim 16 wherein the distal tip is an ultra soft tip.
21. The catheter of claim 20, wherein the ultra soft tip has a durometer hardness of between about 5A to about 40A.
22. The catheter of claim 16, wherein the distal waist section of the inflatable member includes a thermoplastic rubber elastomer.
