Abstract
Abstract A prosthesis and a method for implantation of a prosthesis in the body to cooperate with a body duct to provide a stoma. The prosthesis is particularly characterized by a mesh sleeve, a relatively rigid spout having a proximal end disposed in an opening in the body and a distal end projecting outside of the surface of the body. A layer of biocompatible mesh on the inside of the spout is disposed to engage the serosa of a portion of the body duct to promote growth of the body duct into the layer of mesh to anchor the body duct to the tubular spout. The mesh sleeve is preferably connected with the proximal end of the spout and is wrapped about the body duct and secured to the body wall to allow the serosa of the body duct to grow into the mesh to further anchor the body duct to the body wall. In a preferred embodiment, a fenestrated flange is disposed around the proximal end of the spout, and a removable cap is provided for closing and sealing the spout.

Claim 11
Dependent Claim
49 words
A prosthesis as defined in claim 9 wherein said distal end of said spout includes external threads, and wherein said closure means includes a cap which is internally threaded for engaging said externally threaded distal end of said spout for closing and sealing said distal end of said spout.
Claim 12
Dependent Claim
57 words
A prosthesis as defined in any of claims 1, 2 or 3 wherein said flexible sleeve of mesh material includes a cuff connected with the outer surface of the proximal end of said tubular spout, said flexible sleeve of mesh material also being integrally connected with said layer of mesh on the inside of said tubular spout.
Claim 13
Dependent Claim
