1. A device for providing a compression force to a patient'"'"'s body comprising:
- a covering configured to cover a portion of a patient'"'"'s body, the covering having an outside surface and an inside surface configured to define a first space between the covering and the portion of the patient'"'"'s body;
a sealing band provided proximate an end portion of the covering and configured to provide a fluid tight seal between the covering and the portion of the patient'"'"'s body;
a vacuum source configured to be in fluid communication with the first space so that the application of a vacuum pressure to the first space results in compression of the portion of the patient'"'"'s body; and
a diffusion element located within an aperture of an innermost layer of the covering and configured to be between the vacuum source and the first space and between the outside surface and the first space.

21. A method for providing compression forces to a patient'"'"'s body comprising:
-
covering a portion of a patient'"'"'s body with a covering such that a first space is defined between the covering and the portion of the patient'"'"'s body, wherein the covering includes a diffusion element located within an aperture of an innermost layer of the covering, between a vacuum source and the first space, and between an outside surface of the covering and the first space; providing a seal between the covering and the covered portion of the patient'"'"'s body; and applying a vacuum pressure to the first space resulting in compression of the portion of the patient'"'"'s body. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31)

32. A device for providing a compression force to a patient'"'"'s body comprising:
-
a covering configured to cover a portion of a patient'"'"'s body, the covering having an innermost layer of absorbable material and an outermost layer of elastic material, the covering further having an outside surface and an inside surface configured to define a first space between the covering and the portion of the patient'"'"'s body; a sealing band provided proximate an end portion of the covering and configured to provide a fluid tight seal between the covering and the portion of the patient'"'"'s body; a vacuum source configured to be in fluid communication with the first space so that the application of a vacuum pressure to the first space results in compression of the portion of the patient'"'"'s body, wherein connective tubing is configured to provide fluid communication between the vacuum source and the first space, the tubing being disposed between an inner surface and an outer surface of the sealing band, the tubing being parallel to the outside surface of the covering at the location where it is disposed between the inner and outer surfaces; vent holes in the covering, the vent holes configured to be in fluid communication with the first space so that the application of the vacuum pressure to the first space provides ventilation to the portion of the patient'"'"'s body; and a diffusion element located within an aperture of the innermost layer of the covering and configured to be between the vacuum source and the first space and between the outside surface and the first space.

33. A device for providing a compression force to a patient'"'"'s body comprising:
-
a covering configured to cover a portion of a patient'"'"'s body, the covering having an outside surface and an inside surface configured to define a first space between the covering and the portion of the patient'"'"'s body; a sealing band provided proximate an end portion of the covering and configured to provide a fluid tight seal between the covering and the portion of the patient'"'"'s body; a vacuum source configured to be in fluid communication with the first space so that the application of a vacuum pressure to the first space results in compression of the portion of the patient'"'"'s body; vent holes in the covering, the vent holes configured to be in fluid communication with the first space so that the application of the vacuum pressure to the first space provides ventilation to the portion of the patient'"'"'s body; and a diffusion element located within an aperture of the innermost layer of the covering and configured to be between the vacuum source and the first space and between the outside surface and the first space.
