Abstract

Disclosed herein are various balloon catheter embodiments having a reduced profile (or reduced diameter) section along a length of the catheter body and an inflatable body disposed over the reduced profile section. In certain embodiments, the catheter body has at least one inflation/deflation lumen and a distal inflation/deflation opening defined in a proximal lip of the reduced profile section.

Claims

1. A balloon catheter comprising:

(a) a catheter body comprising;

(i) at least one non-reduced profile body section; and

(ii) a reduced profile body section disposed proximal of a distal end of the catheter body;

(b) an inflatable body disposed over the reduced profile body section;

(c) a guidewire lumen disposed through the standard body section and the reduced profile body section;

(d) at least one inflation/deflation lumen disposed through a proximal portion of the standard body section; and

(e) at least one distal inflation/deflation opening in fluid communication with the at least one inflation/deflation lumen, wherein the at least one inflation/deflation opening is disposed within the inflatable body.

2. The balloon catheter of claim 1, wherein the reduced profile body section has a diameter ranging from about 10% to about 75% of the at least one non-reduced profile body section.

3. The balloon catheter of claim 1, wherein the reduced profile body section has a diameter ranging from about 30% to about 60% of the at least one non-reduced profile body section.

4. The balloon catheter of claim 1, wherein at least one of the at least one non-reduced profile body sections is disposed proximal of the reduced profile body section.

5. The balloon catheter of claim 1, wherein a first non-reduced profile body section is disposed proximal of the reduced profile body section and a second non-reduced profile body section is disposed distal of the reduced profile body section.

6. The balloon catheter of claim 1, further comprising a proximal lip at a proximal end of the reduced profile body section.

7. The balloon catheter of claim 6, wherein the at least one distal inflation/deflation opening is defined in the proximal lip.

8. A balloon catheter comprising:

(a) a proximal catheter body section;

(b) a reduced profile body section distal of the proximal catheter body section;

(c) a distal catheter body section distal of the reduced profile body section;

(d) an inflatable body disposed over the reduced profile body section;

(e) a guidewire lumen disposed through the proximal catheter body section, the reduced profile body section and the distal catheter body section; and

(f) at least one inflation/deflation lumen disposed through the proximal catheter body section and in fluid communication with an interior of the inflatable body.

9. The balloon catheter of claim 8, wherein the reduced profile body section has a diameter ranging from about 10% to about 75% of one of the proximal catheter body section and the distal catheter body section.

10. The balloon catheter of claim 8, wherein the reduced profile body section has a diameter ranging from about 30% to about 60% of one of the proximal catheter body section and the distal catheter body section.

11. The balloon catheter of claim 8, further comprising a proximal lip at a proximal end of the reduced profile body section.

12. The balloon catheter of claim 11, wherein the at least one inflation/deflation lumen comprises a distal inflation/deflation opening in fluid communication with the at least one inflation/deflation lumen, wherein the distal inflation/deflation opening is defined in the proximal lip.

13. A balloon catheter comprising:

(a) a catheter body comprising;

(i) a first body section having a first diameter;

(ii) a second body section disposed proximal to the first body section and having a second diameter, wherein the second diameter is smaller than the first diameter;

(iii) a third body section disposed proximal to the second body section and having a third diameter, wherein the third diameter is substantially equal to the first diameter;

(b) an inflatable body disposed over the second body section;

(c) a guidewire lumen defined through the first, second, and third body sections;

(d) first and second inflation/deflation lumens defined through the first body section;

(e) a first opening in fluid communication with the first inflation/deflation lumen, wherein the first opening is disposed within the inflatable body such that the first inflation/deflation lumen is in fluid communication with an interior of the inflatable body; and

(f) a second opening in fluid communication with the second inflation/deflation lumen, wherein the second opening is disposed within the inflatable body such that the second inflation/deflation lumen is in fluid communication with the interior of the inflatable body.

14. The balloon catheter of claim 13, wherein the second diameter is a diameter ranging from about 10% to about 75% of the first diameter.

15. The balloon catheter of claim 13, wherein the second diameter is a diameter ranging from about 30% to about 60% of the first diameter.

16. The balloon catheter of claim 13, wherein the second diameter is a diameter of about 50% of the first diameter.

17. The balloon catheter of claim 13, further comprising a proximal lip at a proximal end of the second body section.

18. The balloon catheter of claim 17, wherein the first and second openings are defined in the proximal lip.
