Implantable mesh prostheses and method of manufacturing same

摘要

Implantable prostheses for reinforcing and repairing defects in a muscular or tissue wall and a method for fabricating the prostheses that minimizes wasted mesh material and reduces the labor and time required for fabrication. The prosthesis may include a plug body formed of surgical mesh material having a closed end, a larger open end, and a cavity extending therebetween, and a filler body formed of the surgical mesh material comprising a plurality of petals extending radially outwardly from and spaced laterally about a common base disposed in the plug body with the common base attached to the closed end of the plug body. The plug bodies are cut as circular pieces, and the filler bodies are cut as hour-glass shaped pieces from the same sheet of material so as to leave virtually no wasted mesh material. The filler pieces may be attached to the plug body piece by welding.

主权项

1. An implantable prosthesis for repairing a tissue or muscle wall comprising:
a plug body of surgical mesh material, the plug body including a closed end, an open end larger than the closed end, and a cavity extending therebetween, the plug body being constructed and arranged to fit within and occlude a defect in the tissue or muscle wall; and a filler body of surgical mesh material, the filler body comprising a plurality of petals extending radially outwardly from a common base and being spaced laterally thereabout, the filler body being disposed within the cavity with the common base attached to the closed end of the plug body; wherein at least two of the petals are shaped as a longitudinal strip having first and second longitudinal ends and substantially longitudinal opposing side edges, the first and second longitudinal ends being wider than a longitudinal segment intermediate the first and second longitudinal ends, the first and second longitudinal ends each comprising one of the petals; and wherein the plug body has a convex peripheral edge complementary to a concave peripheral edge of the filler body.
