First Claim
Patent Images
1. A device for softening and/or breaking tissue calcifications comprising:
- an elongate tube;
a chamber located at the distal end of the elongate tube, said chamber having a longitudinal axis and being fillable with a liquid; and
a shock wave generator within the chamber, wherein the shock wave generator is arranged to produce a shock wave within the chamber to propagate through the liquid for impinging upon the calcified tissue, and wherein the shock wave generator is carried by an elongate element that is slidably received within the chamber such that the shock wave generator is configured to move from a first location within the chamber to a second location within the chamber that is displaced along the longitudinal axis from the first location.

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 that propagate through the liquid for impinging upon the valve. The shock wave generator is moveable within the balloon to vary shock wave impingement on the valve.
