First Claim
Patent Images
1. A valvuloplasty system, comprising:
- a balloon adapted to be placed adjacent leaflets of a valve, the balloon being inflatable with a liquid;
an embolic protection basket; and
a shock wave generator within the balloon that produces shock waves that propagate through the liquid for impinging upon the valve, the embolic protection basket being arranged for collecting debris resulting from the shock waves impinging upon the valve.

Abstract
A valvuloplasty system comprises a balloon adapted to be placed adjacent leaflets of a valve. The balloon is inflatable with a liquid. The system further includes a shock wave generator within the balloon that produces shock waves. The shock waves propagate through the liquid and impinge upon the valve to decalcify and open the valve. The balloon is carried on a catheter that includes a guidewire lumen. The system further includes a debris collecting basket carried on the catheter proximal to the balloon.

16. A valvuloplasty system, comprising:
-
an elongated tube, the elongated tube having a proximal end, a distal end, and a longitudinal lumen extending there through; a balloon carried on the distal end of the elongated tube and adapted to be placed adjacent leaflets of a valve, the balloon being inflatable with a liquid; a guidewire slidingly received by the longitudinal lumen of the elongated tube for guiding the elongated tube and the balloon along a desired path; and a shock wave generator within the balloon that produces shock waves that propagate through the liquid for impinging upon the valve. - View Dependent Claims (17, 18, 19)

20. A valvuloplasty method of treating a valve having leaflets and an annulus, comprising the steps of:
-
placing a balloon adjacent to the leaflets of the valve; placing an embolic protection basket proximal to the balloon; inflating the balloon with a liquid; producing shockwaves within the balloon that propagate through the liquid for impinging upon the valve leaflets and the valve annulus; and capturing debris resulting from the shockwaves impinging upon the valve annulus and leaflets within the embolic protection basket. - View Dependent Claims (21, 22)

23. A valvuloplasty method for treating a valve having leaflets and an annulus, comprising:
-
providing an elongated tube having a proximal end, a distal end, and a longitudinal lumen extending there through, a balloon, inflatable with a liquid, carried on the distal end of the elongated tube and adapted to be placed adjacent leaflets of a valve, a guide wire, and a shock wave generator within the balloon that produces shock waves that propagate through the liquid for impinging upon the valve; advancing the guide wire along a desired path through the valve annulus; sliding the elongated tube onto the guide wire and advancing the elongated tube on the guide wire until the balloon is adjacent the valve leaflets; inflating the balloon with the liquid; and producing shockwaves within the balloon with the shock wave generator. - View Dependent Claims (24)
