Abstract

Catheters that includes inner and outer elongate shafts, each of which is secured relative to an end of an inflatable member. Balloon bonding locations may be disposed radially inward relative to an outer dimension of the outer elongate shaft.

Claims (26)

1. A catheter with a proximal variable transition zone, comprising:

a hub disposed at a proximal region of the catheter, the hub including one or more fluid ports;

a catheter shaft disposed within an internal volume of the hub, the catheter shaft in fluid communication with a first of the one or more fluid ports, the catheter shaft extending further distally than the hub;

a first strain relief member disposed about a distal end of the hub and extending distally beyond the hub, the catheter shaft extending within the first strain relief member and further distally than the first strain relief member;

a second strain relief member with a proximal end disposed within the internal volume of the hub, the second strain relief member extending distally through the first strain relief member and extending distally beyond the first strain relief member, the second strain relief member disposed around the catheter shaft, the catheter shaft extending further distally than the second strain relief member, and

the second strain relief member having a distal end and a length, the second strain relief member having a variable flexibility along at least a portion of its length,

the second strain relief member having a flexibility where it extends from a distal end of the first strain relief member that is less than a flexibility of the distal end of the second strain relief member.

2. The catheter of claim 1 , wherein the proximal end of the second strain relief member is secured relative to the internal volume of the hub, and wherein the distal end of the second strain relief member is not adhered to the catheter shaft such that the distal end of the second strain relief member is free to move relative to the catheter shaft.

3. The catheter of claim 1 , wherein the flexibility of the distal end of the second strain relief member substantially matches a flexibility of the catheter shaft at a location of the distal end of the second strain relief member.

4. The catheter of claim 3 , wherein the flexibility of the second strain relief member where it extends from the distal end of the first strain relief member is the same or substantially similar to a flexibility of the distal end of the first strain relief member, the flexibility of the second strain relief member where it extends from the distal end of the first strain relief member and the flexibility of the distal end of the first strain relief member being the same or substantially similar so as to reduce kinking between the first strain relief member and the second strain relief member.

5. The catheter of claim 1 , wherein the flexibility of the distal end of the second strain relief member is the same or substantially similar to a flexibility of the catheter shaft where the catheter shaft extends from the distal end of the second strain relief member, the flexibility of the distal end of the second strain relief member and the flexibility of the catheter shaft being the same or substantially similar so as to reduce or prevent kinking between the second strain relief and the catheter shaft.

6. The catheter of claim 1 , wherein an amount of kinking of the catheter shaft at a location immediately distal to the distal end of the first strain relief member is less than a degree of kinking that would occur in the absence of the second strain relief member.

7. The catheter of claim 1 , wherein the proximal end of the second strain relief member includes a solid tubular member.

8. The catheter of claim 1 , wherein the second strain relief member includes a plurality of cuts formed therein.

9. The catheter of claim 8 , wherein the plurality of cuts impart more flexibility in a distal region of the second strain relief member than in a proximal region of the second strain relief member.

10. The catheter of claim 1 , wherein the second strain relief member has a plurality of cuts formed therein, the distribution of the cuts providing a distal section with a flexibility that is greater than a flexibility in the proximal section.

11. The catheter of claim 1 , wherein the second strain relief member is more flexible in a distal section that includes the distal end than in a proximal section that includes the proximal end.

12. The catheter of claim 1 , wherein the second strain relief member has a first section with a first flexibility and a second section with a second flexibility, the second section distal to the first section and more flexible than the first section.

13. The catheter of claim 12 , wherein the second section is distal to the hub, and the first section is disposed at least partially within the hub.

14. The catheter of claim 13 , wherein the second strain relief member has a third section with a third flexibility, the third section being distal to the second section, the third section being more flexible than the second section.

15. The catheter of claim 13 , wherein the third section has a gradient flexibility, with increasing flexibility in a distal direction.

16. The catheter of claim 12 , wherein the first section has a gradient flexibility.

17. The catheter of claim 1 , wherein the second strain relief member comprises a cylindrical body.

18. The catheter of claim 1 , wherein the first strain relief member comprises a conical section.

19. The catheter of claim 1 , wherein the second strain relief member has four or more sections, each of which has a flexibility profile that is different than each of the other sections.

20. The catheter of claim 1 , wherein the second strain relief member comprises stainless steel.
