Abstract
A composite prosthesis and method for limiting the incidence of postoperative adhesions. The composite includes a mesh fabric and a barrier which prevents exposure of the mesh fabric to areas of potential adhesion. The interstices of the mesh fabric are infiltrated by tissue which secures the prosthesis in place. The composite is positioned with the barrier relative to the region of potential adhesion, such as the abdominal viscera.
Claims5
A method for limiting the incidence of postoperative adhesions arising from a repair of an opening in a tissue or muscle wall, wherein the opening is located near a region of potential postoperative adhesion, comprising:
- providing a composite prosthesis including an implantable material constructed and arranged to occlude the opening and having a plurality of interstices constructed and arranged to allow tissue ingrowth, and a barrier which does not substantially stimulate the formation of postoperative adhesions, the barrier covering the implantable material, whereby the composite prosthesis is securable in place by growth of neighboring tissue into the implantable material;
- and
- positioning the composite prosthesis for limiting the formation of postoperative adhesions with the implantable material filling or covering, thereby occluding, the tissue or muscle wall opening, and with the barrier facing away from the tissue or muscle wall opening and extending between the region of potential postoperative adhesion and the implantable material.
