Abstract: A method of sizing a breast prosthesis and implanting an accurately sized breast prosthesis is disclosed. The method invovles implanting an empty, inflatable elastomeric balloon in a breast, filling the balloon with a liquid to a desired size, measuring the amount of liquid in the filled balloon, removing the liquid from the balloon, and removing the empty balloon from the breast. A final breast prosthesis is sized in accordance with the amount of liquid that was in the filled balloon. The properly sized final breast prosthesis is then implanted into the breast.

Abstract: A pressure sensing device includes a sensor for continuously measuring the pressure on a patient's skin at the interface between the skin and a surface exerting pressure on the skin. A monitoring device monitors the pressure exerted on the skin and the elapsed time period during which the skin has been exposed to the measured pressure. An alarm then indicates when the combination of the pressure and the elapsed time is approaching a previously determined level in order to prevent damage to the patient's skin.
