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.
