Abstract

Claims (14)

1. A method for delivering high intensity focused ultrasound energy to a skin surface, the method comprising:

applying a thin film of fluid consisting of water having less than 1% impurities by weight on the skin surface so the skin surface is at least lightly moistened;

placing a high intensity focused ultrasound transducer on to the moistened skin surface;

pressing the ultrasound transducer against the skin surface so that said film of water is distributed between the skin surface and the transducer.

2. The method of claim 1 , wherein the film of fluid contains a surfactant.

3. The method of claim 1 , wherein the film of fluid contains an anti-microbial agent.

4. The method of claim 1 , wherein the film of fluid is applied by spraying under conditions such that beading up and rolling of the water is inhibited.

5. The method of claim 1 , further comprising cleaning the skin surface prior to applying the film of fluid on the skin surface.

6. The method of claim 1 , further comprising repositioning the high intensity focused ultrasound transducer on the skin surface.

7. The method of claim 1 , wherein applying the film of fluid comprises spraying the volume of fluid.

8. The method of claim 1 , wherein applying comprises:

applying the film of fluid on to a small skin surface; and
