    摘要: Described are medical graft products, systems, and methods for treating fistulae. Certain products of the invention are configured to have portions residing in and around a primary fistula opening, e.g., one occurring in a wall of the alimentary canal. One such product includes a biocompatible graft body which is configured to block at least the primary opening. The graft body includes a capping member, which is configured to contact portions of the alimentary canal wall adjacent to the primary opening, and an elongate plug member extending from the capping member, which is configured to extend into at least a portion of the fistula. In certain embodiments, a graft body component has the capacity to expand or otherwise change form to provide a suitable capping arrangement. Such a component can include a resilient wire frame, e.g., one that is self-expandable or one that requires at least some manipulation in order to expand.

    摘要: Described are embodiments of a multilaminate or multiple layer implantable surgical graft with an illustrative graft comprising a remodelable collagenous sheet material, the graft including one or more interweaving members to stitch together the graft to help prevent the layers from delaminating or separating during handling and the initial stages of remodeling. The interweaving members may comprise lines of suture, thread, individual stitches, strips of material, etc. that are woven through the layers of biomaterial in a desired pattern. In one embodiment, the interweaving members comprise a pharmacologically active substance, such as a drug, growth factors, etc. to elicit a desired biological response in the host tissue. In another embodiment, the graft further comprises a reinforcing material, such as a synthetic mesh, within the layers of remodelable biomaterial and stitched together by one or more interweaving members.
