Abstract
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.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
115 words
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body whereby upon rupture or cutting of said membrane the coiled portion of said elongated member can be extended and withdrawn from said cup-shaped body while the artificial stoma is implanted.
Claim 2
Dependent Claim
115 words
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body whereby upon rupture or cutting of said membrane the coiled portion of said elongated member can be extended and withdrawn from said cup-shaped body while the artificial stoma is implanted.
Claim 3
Dependent Claim
16 words
An artificial cutaneous stoma as defined in claim 1 wherein said elongated member is a catheter.
Claim 4
Dependent Claim
18 words
An artificial cutaneous stoma as defined in claim 1 wherein said elongated member includes an electrically conductive element.
Claim 5
Dependent Claim
18 words
An artificial cutaneous stoma as defined in claim 3 wherein said elongated member is a cardiac pacemaker lead.
Claim 6
Dependent Claim
18 words
An artificial cutaneous stoma as defined in claim 1 wherein said elongated member is a fiber optic element.
Claim 7
Dependent Claim
23 words
An artificial cutaneous stoma as defined in claim 1 wherein said elongated member is permanently affixed to the bottom of said cup-shaped body.
Claim 8
Dependent Claim
36 words
An artificial cutaneous stoma as defined in claim 1 wherein said cup-shaped member has a tubular member affixed to and extending from the bottom thereof and has another elongated member slidably positioned within said tubular member.
Claim 9
Dependent Claim
23 words
An artificial cutaneous stoma as defined in claim 1 wherein said closure membrane is peripherally adhered to the top surface of said flange.
Claim 10
Dependent Claim
38 words
An artificial cutaneous stoma as defined in claim 1 wherein the elongated member coiled within the cup-shaped body has been exteriorized through the closure member and the cup-shaped body has been filled with a physiologically inert flexible material.
Claim 11
Dependent Claim
20 words
The artificial cutaneous stoma of claim 9 wherein the physiologically inert flexible material is a room temperature vulcanizable silicone rubber.
