Abstract
A combination is provided of a percutaneous lead designed for implantation in the human body, which lead has a surface which is adapted to pass through and be exposed to the dermis of a patient when the device is implanted. Said surface is adapted to receive the growth of a cultured autogenous fibroblast coating on an etched, nanoporous surface. A liquid tight sealed removable, disposable chamber encloses said surface, said chamber being provided with openings for introduction therein of finely divided living dermal tissue suspended in a liquid carrier, thus providing a means for formation of the cultured surfaces which can be easily handled. The disposable chamber is removed and discarded at the time of surgery.
