Abstract
A percutaneous access device includes a body having a horizontal disc-like base flange and a frusto conical projection extending centrally upwardly from one side of the base flange. An elongate flexible tube extends loosely through a bore through the projection and base flange and is sealingly bonded to the body adjacent the bottom of the bore. A coating of a silicone-polycarbonate is applied to the outer surface of the projection and is formed with a multiplicity of microscopic pores to facilitate the bonding of dermal cells to the device upon implantation. The body is of a relatively soft, flexible, biocompatible material so that the device absorbs forces tending to displace the implanted device.
