Abstract

A shock wave applicator includes a shock wave generator and an asymmetrical reflector portion in a housing. Asymmetry of the reflector portion is combined with one or more wave generators to produce a variety of focal volumes and wave fronts for medical treatment.

Claims

1. A shock wave device comprising:

a shock wave applicator including a reflector disposed within a housing;

wherein the reflector is a portion of an ellipsoidal shape, the ellipsoidal shape having a first focal point and a second focal point;

wherein the reflector terminates at an edge defining an opening on a plane; and

a means for shock wave generation disposed in the housing at the first focal point of the ellipsoidal shape that establishes a focal line with the second focal point of the ellipsoidal shape;

wherein said focal line intersects the plane defined by the terminating edge of the reflector at a non-perpendicular angle.

2. The shock wave device of claim 1, wherein the reflector defines a continuous interior within the housing.

3. The shock wave device of claim 1, wherein the shock wave applicator further includes a ultrasonic visualization device disposed in the housing.

4. The shock wave device of claim 1, further including a cushion disposed on the housing around the terminating edge of the reflector.

5. The shock wave device of claim 1, further including a handle coupled to the housing.
