Abstract: A surgically implantable prosthetic device includes a first shell having an exterior surface, an interior surface, and enclosing a lumen, wherein the lumen enclosed by the first shell is able to accommodate a first fluid therein. The prosthetic device further includes a second shell having an exterior surface, an interior surface, and enclosing a lumen, wherein the lumen enclosed by the second shell is able to accommodate a second fluid therein. One or more fitted shells arranged adjacent to and in a graduated relation to each other are situated between the exterior surface of the second shell and the interior surface of the first shell. The one or more shells include an innermost fitted shell and an outermost fitted shell, wherein the innermost fitted shell is adjacent to the exterior surface of the second shell and the outermost fitted shell is adjacent to the interior surface of the first shell.

Abstract: A surgical device for removing implanted devices includes a sleeve device with an elongated trough portion arranged to extend through a skin opening and be positioned subjacent to a particular implanted device. A removable knife assembly is inserted through a tubular portion of the sleeve device and is used to incise scar tissue from a proximal end of the implanted device. The implanted device is then manipulated through the opening in the surrounding scar tissue and deposited on the trough portion of the sleeve device whereupon it is removed through the skin opening. The surgical device may also include a removable trochar device slidably engaging the tubular portion of the sleeve device and penetrating flesh to the implanted device.
