Abstract

A medical device for use on a bodily organ includes a concave support element that is removably attachable to the surface of the bodily organ, thereby defining an enclosed space adjacent to the bodily organ. The enclosed space is fluidly connected to a fluid management system for circulating a fluid inside of the enclosed space. The medical device also has an energy transfer element mounted to the concave support element and electrically connected to a control unit. In some embodiments, the energy transfer element transmits intense ultrasound energy in a frequency range of 1–30 megahertz, and the fluid acoustically couples the energy transfer element to the bodily organ, and the fluid also cools the energy transfer element.

Claims

1. A medical device for use on a bodily organ of a patient, the medical device comprising:

a) a support element defining a cavity and having an open portion that is removably attachable to the surface of the bodily organ, thereby defining an enclosed space adjacent to the bodily organ;

b) an energy transfer element mounted to the support element, the energy transfer element positioned and oriented for transmitting energy directly to the bodily organ;

c) a vacuum source fluidly connected to the enclosed space; and

d) a plurality of hooks mounted on the support element for removably attaching the support element to the bodily organ.

2. The medical device of claim 1, wherein the enclosed space is fluidly connected to a fluid management system for circulating a fluid inside of the enclosed space.

3. The medical device of claim 1, wherein the support element further comprises an enclosure member containing a fluid and the energy transfer element and the energy transfer element transmits intense ultrasound energy in a frequency range of 1–

30 megahertz, and the fluid acoustically couples the energy transfer element to the bodily organ.

4. The medical device of claim 1, wherein the vacuum source creates an operating pressure within the enclosed space that is lower than the pressure external to the support element.

5. The medical device of claim 1 further comprising positioning means for adjusting the position of the energy transfer element with respect to the bodily organ.

6. The medical device of claim 1, wherein the support element is conformable to the shape of the bodily organ.
