SHOCKWAVE VALVULOPLASTY WITH MULTIPLE BALLOONS
First Claim
1. A device for treatment of a heart valve, wherein the heart valve has a plurality of cusps each having a concave portion, comprising:
- a first elongate body;
a first balloon sealably enclosing a portion of the first elongate body;
a first shock wave source coupled to the first elongate body and enclosed within the first balloon;
a second elongate body;
a second balloon sealably enclosing a portion of the second elongate body;
a second shock wave source coupled to the second elongate body and enclosed within the second balloon; and
wherein the first and second balloons are independently inflatable with a liquid and are sized and shaped such that when inflated with the liquid, a portion of the balloons contact the valve, and wherein the portion of the balloons that contact the valve approximate the size and shape of a concave portion of a valvular cusp.

Abstract
Described herein are shock wave devices and methods for the treatment of calcified heart valves. One variation of a shock wave device includes three balloons that are each sized and shaped to fit within a concave portion of a valve cusp when inflated with a liquid and a shock wave source within each of the three balloons. Each balloon is separately and/or independently inflatable, and each shock wave source is separately and/or independently controllable. Methods of treating calcified heart valves using a shock wave device can include advancing a shock wave device having one or more balloons and a shock wave source in each of the balloons to contact a heart valve, inflating the one or more balloons with a liquid such that the balloon is seated within a concave portion of a valve cusp, and activating the shock wave source.

13. A method for applying shock waves to an aortic valve comprising:
-
introducing shock wave device into a patient'"'"'s vasculature, the shock wave device comprising a first elongate body, a first balloon sealably enclosing a portion of the first elongate body, a first shock wave source coupled to the first elongate body and enclosed within the first balloon, a second elongate body, a second balloon sealably enclosing a portion of the second elongate body, and a second shock wave source coupled to the second elongate body and enclosed within the second balloon, wherein the first and second balloons are independently inflatable with a liquid; advancing the shock wave device within the vasculature to contact an aortic valve having a first cusp and a second cusp; inflating the first balloon with a liquid, wherein inflating the first balloon causes the first balloon to be aligned within a concave portion of the first cusp; and activating the first shock wave source to apply a shock wave to the first cusp. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
