Abstract
A reduced-pressure system for treating tissue, such as damaged subcutaneous tissue, includes a shaped dressing bolster for placing on the patient's epidermis and substantially sized to overlay the damaged subcutaneous tissue. The system further includes a sealing subsystem for providing a fluid seal over the shaped dressing bolster and a portion of the patient's epidermis, and a reduced-pressure subsystem for delivering a reduced pressure to the sealing subsystem. The reduced-pressure system may develop a force, which may include a vertical force that is realized at tissue site deeper than the epidermis or a closing force directed towards the incision. The shaped dressing bolster is shaped to evenly distribute the force. Other methods and systems are included.
