First Claim
Patent Images
1. An artificial cutaneous stoma for percutaneous passage of an elongated body insertable member, comprising:
- A generally cup-shaped body of surgically implantable material including a flange extending beyond the periphery of the cupshaped portion, tissue ingrowth means affixed to the external surface of said cup shaped body, a flexible elongated body insertable member having an end portion thereof extending through the bottom of said body and the remainder thereof coiled within the cup-shaped portion thereof, and a closure membrane closing the top of said cup-shaped body whereby upon rupture or cutting of said membrane the coiled portion of said elongated member can be extended and withdrawn from said cup-shaped body while the artificial stoma is implanted.

Abstract
A device for providing a long term percutaneous pathway for elongated members such as catheters, pacemaker leads, fiber optics, and the like, comprising a flanged cup-shaped body containing coils of the elongated member or members and having tissue fixation means on its surface, at least one aperture in the bottom of the body through which the elongated members pass and to which the elongated member may be permanently affixed and a membranous cover designed to be cut along with overlying skin for withdrawal of the coiled portion of the elongated member after cutaneous implantation and healing.
