Abstract

Balloon catheters and methods of making and using the same. A balloon catheter may include a catheter shaft and a balloon coupled thereto. A traction member may be coupled to the balloon catheter adjacent the balloon and may extend along a portion or all of the length of the balloon. The traction member can improve traction between the balloon and a target site.

Claims (24)

1. A balloon catheter, comprising:
an elongate catheter shaft having a distal end, an inflation lumen defined therein, and a guidewire lumen defined therein;
a balloon coupled to the shaft and disposed adjacent the distal end of the shaft;
a traction member having a first end and a body portion, the first end being coupled to the balloon catheter proximate the distal end of the shaft and the body portion extending proximally over at least a portion of the balloon; and one or more gripping regions defined in the body portion.
2. The balloon catheter of claim 1, wherein the one or more gripping regions are defined by one or more bumps disposed on the body portion.
3. The balloon catheter of claim 1, wherein the one or more gripping regions are defined by a helical winding formed in the body portion.
4. The balloon catheter of claim 1, wherein the one or more gripping regions are defined by a ridge along the body portion.
5. The balloon catheter of claim 1, wherein the one or more gripping regions are defined by one or more saw-tooth projections along the body portion.
6. The balloon catheter of claim 1, wherein the one or more gripping regions are defined by one or more spikes along the body portion.
7. The balloon catheter of claim 1, wherein the one or more gripping regions are defined by an undulation along the body portion.
8. The balloon catheter of claim 1, wherein the traction member includes a second end coupled to the balloon catheter at a position proximate the proximal end of the balloon.
9. The balloon catheter of claim 1, wherein a portion of the guidewire lumen is arranged coaxially with the balloon.
10. The balloon catheter of claim 9, further comprising a guidewire disposed in the guidewire lumen and extending distally out of a distal end of the guidewire lumen.
11. The balloon catheter of claim 1, wherein the first end of the traction member is coupled to the shaft.
12. The balloon catheter of claim 1, wherein the first end of the traction member is coupled to the balloon.
13. The balloon catheter of claim 1, wherein the traction member includes a proximal end coupled to the shaft.
14. The balloon catheter of claim 1, wherein a proximal end of the traction member is disposed adjacent a proximal waist of the balloon.
15. The balloon catheter of claim 1, wherein a proximal end of the traction member is disposed adjacent a midpoint of the balloon.
16. The balloon catheter of claim 1, wherein a proximal end of the traction member is disposed adjacent a distal waist of the balloon.
17. A medical device, comprising:
a catheter shaft having a guidewire lumen defined therein;
a balloon coupled to the shaft, the balloon being substantially coaxially arranged with respect to at least a region of the guidewire lumen; and a traction member having a distal end coupled to the balloon catheter at a position proximate distal end of the shaft and extending in the proximal direction and along the balloon.
18. The medical device of claim 17, wherein the traction member includes one or more gripping surfaces defined along at least a portion thereof.
19. The medical device of claim 17, wherein the traction member includes a gripping region defined along at least a portion thereof.
20. The medical device of claim 17, wherein the traction member includes a proximal end coupled to the shaft.
21. The medical device of claim 17, wherein the traction member include a proximal end that is not attached to the shaft and is disposed adjacent the balloon.
22. The medical device of claim 21, wherein the proximal end of the traction member is disposed adjacent a proximal waist of the balloon.
23. The medical device of claim 21, wherein the proximal end of the traction member is disposed adjacent a midpoint of the balloon.
24. The medical device of claim 21, wherein the proximal end of the traction member is disposed adjacent a distal waist of the balloon.
