Abstract: A therapeutic garment includes at least one first expandable bladder configured to underlie a wearer's left shoulder blade, at least one second expandable bladder configured to underlie the wearer's right shoulder blade, and an actuator configured to alternatingly (a) expand the at least one first expandable bladder from a collapsed state to an expanded state such that the wearer's torso is rolled in a rightward direction and (b) expand the at least one second expandable bladder from a collapsed state to an expanded state such that the wearer's torso is rolled in a leftward direction.

Abstract: A device and method for alleviating pressure on a portion of a patient's body that may be bed-ridden or otherwise constrained for long periods of time. A position of the mechanism is based upon a location or distribution of angiosomes in the body portion. The mechanism includes a pump, and a portable garment with inflatable channels and pressure relievers. The channels provide varying pressure on the body portion, a maximum pressure being set at a level sufficient for treating or preventing decubitus ulcer formation on the body portion. The channels are positioned based upon angiosome distribution in the portion of the body. The pressure relievers protect tissue on bony prominences from excess pressure.

Abstract: An apparatus for treating or preventing decubitus ulcers includes: a garment sized and shaped to be worn by a patient; a first plurality of fluid channels and a second plurality of fluid channels coupled to the garment and disposed adjacent to one another, at least some of the first plurality of fluid channels being independently inflatable and deflatable as compared with at least some of the second plurality of fluid channels; and a fluid control mechanism coupled to the first and second plurality of fluid channels and operating to repeatably and sequentially inflate and deflate the independently inflatable and deflatable fluid channels from among the first and second plurality of fluid channels such that there is less than a predetermined level of pressure exerted on the patient's tissue under one or more of the deflated channels.
