Abstract

A flexible PTCA and/or PTA device is disclosed which respects the curves of the anatomy for dilatation, centering and setting stents. A method for inflation is also disclosed.

Claims

1. PTCA and/or PTA inflation device for a catheter comprising:

a balloon; and

at least one region of the balloon with a defined adjustable compliance.

9. PTCA and/or PTA inflation device according to claim 1, having a total length (L1) in a range 6 mm to 50 mm.

11. PTCA and/or PTA inflation device according to claim 1, having no more than 5 balloon lobes in line.

12. PTCA and/or PTA inflation device according to claim 1, having at least two knobs.

13. Method for inflating the PTCA and/or PTA inflation device of claim 1, comprising:

a first phase for inflating the balloon; and

.

a second phase for inflating the balloon.

14. Method for inflating the PTCA and/or PTA inflation device according to claim 13, comprising:

applying the inflation device for at least one of dilatation, bifurcation dilatation, centering, stenting, osteal stenting, and bifurcation stenting.

15. PTCA and/or PTA inflation device according to claim 1, comprising:

an outer tube; and

an inner tube wherein the outer tube is welded with a proximal end of the device, the inner tube is welded with a distal end of the device, and the outer tube is welded in at least one position with the inner tube such that hollow spaces are generated along an axis for inflation and/or deflation of the device.

16. PTCA and/or PTA inflation device according to claim 15, wherein the welding point of the inner tube with the distal end of the device is in an inner range of the device.

21. PTCA and/or PTA inflation device according to claim 1, having a total length (L1) in a range 8 mm to 40 mm.

2. PTCA and/or PTA inflation device for a catheter, comprising:

a balloon; and

at least two regions with at least two different defined compliances.

3. PTCA and/or PTA inflation device according to claim 2, comprising:

at least two balloon lobes with a waist between the balloon lobes.

4. PTCA inflation device according to claim 3 having a diameter (D1) of the waist in a range from 1 mm to 2 mm.

5. PTA inflation device according to claim 3 having a diameter (D1) of the waist in a range from 1 mm to 5 mm.

6. PTCA inflation device according to claim 4 having a diameter (D2) of the balloon lobes in a range from 1 mm to 5 mm.

7. PTA inflation device according to claim 5 having a diameter (D2) of the balloon lobes in a range from 1 mm to 30 mm.

8. PTCA and/or PTA inflation device according to claim 3, wherein diameters (D3, D4) of the balloon lobes are different.

10. PTCA and/or PTA inflation device according to claim 3, wherein the balloon lobes have a length (L2) in a range of 3 mm to 40 mm.

17. PTCA inflation device according to claim 3 having a diameter (D1) of the waist in a range from 1.1 mm to 1.5 mm.

18. PTA inflation device according to claim 3 having a diameter (D1) of the waist in a range from 1.1 mm to 4.5 mm.

19. PTCA inflation device according to claim 4 having a diameter (D2) of the balloon lobes in a range from 2 mm to 4 mm.

20. PTA inflation device according to claim 5 having a diameter (D2) of the balloon lobes in a range from 2 mm to 15 mm.

22. PTCA and/or PTA inflation device according to claim 3, wherein the balloon lobes have a length (L2) in a range of 4 mm to 10 mm.
