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

Abstract
A valvuloplasty system includes 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.
