One aspect relates to reducing a pressure differential across one or more supporting surfaces of a body surface of an individual at least partially by displacing at least one displaceable contouring unit to at least partially conform to one or more contours of the body surface of the individual. Certain aspects can relate to stabilizing at least the one or more supporting surfaces of the body surface of the individual at least partially with at least one of the at least one displaceable contouring unit Other aspects can relate to relatively displacing at least one displaceable contouring unit with respect to a medical device portion based at least in part on a contour of an individual to support at least a portion of the individual while limiting pressure applied to the individual.
