First Claim
Patent Images
1. An implantable prosthesis for repairing a tissue or muscle wall defect, comprising:
- a flexible plug, formed of a surgical mesh fabric having openings therein for tissue ingrowth, and constructed and arranged to securely fit within and occlude the tissue or muscle wall defect wherein at least a portion of said flexible plug includes a pleated surface which allows radial into the defect without kinking or buckling so that said plug conforms to irregularities in the tissue or muscle wall defining the defect, said flexible plug being compressible radially upon insertion into the defect from a first configuration which is larger than the defect to a second configuration which closely approximates the shape of the defect.

13. An implantable prosthesis for repairing a tissue or muscle wall defect, comprising:
-
a flexible plug, formed of a surgical mesh fabric having openings therein for tissue ingrowth, which tapers outwardly from a closed end to a larger end and having a cavity which is defined therebetween, wherein at least a portion of said tapered plug includes a pleated surface which allows radial compression of said pleated portion of said plug upon insertion into the defect without kinking or buckling so that said plug conforms to irregularities in the tissue or muscle wall defining the defect, said flexible plug being compressible radially upon insertion into the defect from a first configuration which is larger than the defect to a second configuration which approximates the shape of the defect so that said plug securely fits therein and occludes the defect; a first filler body formed of surgical mesh fabric having openings therein for tissue ingrowth, including a common base and a plurality of petals extending upwardly from said base and being spaced laterally thereabout, said base being supported by said plug so that said plurality of petals project into said cavity, whereby said plurality of petals stiffen said implantable prosthesis when said plug is compressed into said second configuration upon insertion into the defect. - View Dependent Claims (14, 15, 16, 17)

18. An implantable prosthesis for repairing a tissue or muscle wall defect, comprising:
-
a conical plug, formed of a surgical mesh fabric having openings therein for tissue ingrowth, including an atraumatically configured end, a larger open end and a cavity extending therebetween, said conical plug constructed and arranged to securely fit within and occlude the tissue or muscle wall defect wherein at least a portion of said conical plug includes a pleated surface which allows radial compression of said pleated portion upon insertion of said plug into the defect without kinking or buckling so that said plug conforms to irregularities in the tissue or muscle wall defining the defect, said conical plug being radially compressible upon insertion into the defect from a first configuration which is larger than the defect into a second configuration which approximates the shape of the defect; a plurality of petals, formed of a surgical mesh fabric having openings therein for tissue ingrowth, being positioned in said cavity and extending upwardly from said atraumatically configured end of said plug and being moveable relative to said plug, whereby said plurality of mesh petals stiffen said implantable prosthesis when said plug is compressed into said second configuration upon insertion into the defect.

21. A method of repairing a tissue or muscle wall defect, comprising:
-
providing an implantable prosthesis including a plug formed of a surgical mesh fabric which is compressible from a first configuration which is larger than the defect into a second configuration which approximates the shape of the defect so that the plug securely fits therein and occludes the defect, the plug including an inner filler body formed of spaced petals of a surgical mesh fabric which stiffen the implantable prosthesis when the plug is compressed into the second configuration; placing the plug in the defect so that the plug compresses into the second configuration; and detaching one or more petals from the inner filler body to vary the stiffness of the implantable prosthesis.
