Abstract: The invention is a method for treating or preventing pressure sores. It comprises (i.e., includes but is not limited to) the following steps: applying a cushion in indirect contact or in direct contact with substantially the entire surface of a pressure sore area, and applying pressure against the pressure sore area through the cushion. The cushion is preferably circular in shape (although it may have other shapes) with its diameter between about 1.5 and about 6 times its height, and preferably between about 3 and about 4 times its height. In the preferred embodiment, the cushion has a silicone elastomeric shell, with the portion of the shell intended to be in occlusive contact with the pressure sore having a smooth outer surface. In the preferred embodiment, the cushion is only partially filled, and the fill material is silicone gel. The cushion may be held in place by means of a strap, wrap, bandage or similar device.
