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.
A prosthesis for implantation in a body wall for cooperating with a body duct to provide a stoma, said prosthesis comprising a flexible sleeve of biocomptible mesh material for being wrapped about a portion of a body duct passing through an opening in the body wall, a relatively rigid tubular spout of nonporous biocompatible material having a proximal end connected with said sleeve, said relatively rigid tubular spout having a distal end and being dimensioned such that when said proximal end is implanted in the opening in the body wall said distal end protrudes outwardly of the body wall, and a flange of biocompatible material surrounding the proximal end of the relatively rigid tubular spout for disposition beneath the subcuticular fascia of the body wall when the proximal end of the spout is implanted in the body wall.
A prosthesis for implantation in a body wall for cooperating with a body duct to provide a stoma, said prosthesis comprising a flexible sleeve of biocompatible mesh material for being wrapped about a portion of the body duct passing through an opening in a body wall, a relatively rigid tubular spout of nonporous biocompatible material, said relatively rigid tubular spout having a proximal end designed for implantation in the body wall and said flexible sleeve being connected with said proximal end of said spout for implantation therewith in the body wall, said tubular spout having an inner surface circumscribing the inside thereof, said spout having a layer of mesh of biocompatible material on the inside thereof disposed to engage the body duct to promote in-growth of connective tissue from the adjacent tissue of the body duct and to anchor the body duct in the interior of the spout.
A method of making a stoma in a body wall, comprising the steps of implanting a relatively rigid tubular spout of nonporous biocompatible material in an opening in the body wall such that a proximal end portion of the relatively rigid tubular spout is disposed between the inner and outer surfaces of the body wall and a distal end portion of the rigid tubular spout extends outside of the body wall, passing a body duct through the body wall and into an opening in the spout to bring the serosa of the portion of the body duct passing into the opening in the spout into contact with a layer of mesh of biocompatible material in the opening in the spout, wrapping a flexible mesh of biocompatible material about the portion of the body duct passing through the remainder of the body wall and securing a portion of the flexible mesh to the body wall to maintain the serosa of the body duct in contact with the flexible mesh wrapped thereabout.
