Abstract
Abstract A chronic transcutaneous implant device for enterostomies is disclosed. The implant device is comprised of a barrel portion and flange portion. The barrel portion is provided with means to enable vascularization of the externalized vessel and the flange portion is provided with means to enable the formation of a vascularized biological anchor. The implant device is capable of being permanently positioned under the skin. The implant device is provided with a detachable bag member which functions to receive excrements exiting the externalized vessel.

Claim 1
Independent Claim
76 words
A chronic transcutaneous substantially non-absorbing, impermeable, biocompatible and non-biodegradable implant device comprising: a barrel member open at each end, said barrel member being further defined as including at least one annular groove at one end thereof; a flange member extending from and secured to the exterior of said barrel member, said flange member including a plurality of apertures; and a suture ring attached about said barrel member annular groove and extending longitudinally from said barrel member.
Claim 2
Dependent Claim
76 words
A chronic transcutaneous substantially non-absorbing, impermeable, biocompatible and non-biodegradable implant device comprising: a barrel member open at each end, said barrel member being further defined as including at least one annular groove at one end thereof; a flange member extending from and secured to the exterior of said barrel member, said flange member including a plurality of apertures; and a suture ring attached about said barrel member annular groove and extending longitudinally from said barrel member.
Claim 3
Dependent Claim
17 words
The implant device of claim 1 wherein said barrel and flange consist essentially of a polymeric carbon.
Claim 4
Dependent Claim
25 words
The implant device of claim 1 wherein said barrel is flared at one end and said flange is located along the length of said barrel.
Claim 5
Dependent Claim
71 words
An implant device as defined in claim 1, wherein the external shape of the body is a surface of revolution and having a lateral surface substantially as defined by the equation R=R o +f(h) in polar coordinates: where R is the radius, H is the total height, and h is the distance from the top of the implant; For h≦0.6H; (x=h/H) f=h(0.1+1.28x-7.38x.sup.2 +14.6x.sup.3 -12.83x.sup.4 +4.28x.sup.5) For h≦0.6H; (x=h/H) f=H(3.2x+35.7x.sup.2 +159.0x.sup.4 -69.5x.sup.5).
