Abstract
An implantable prosthesis for repairing or reconstructing a tissue or muscle wall defect including an outer plug and at least two inner filler plugs positioned within the outer plug that stiffen, and impart bulk to, the outer plug when the implant is inserted into the narrow confines of the tissue or muscle wall defect.
Claims20
An implantable prosthesis for repairing or reconstructing a tissue or muscle wall defect, comprising:
- a flexible, hollow outer plug formed of a biologically compatible, implantable fabric having openings therein for tissue ingrowth, said hollow plug including a cavity therein and being compressible radially upon insertion into the defect;
- and
- at least two inner filler plugs pre-formed to include a sidewall defining a cavity in an uncompressed configuration, and being further formed of a biologically compatible, implantable fabric having openings therein for tissue ingrowth and positioned within said outer plug cavity which impart bulk to, and stiffen, said implantable prosthesis when said outer plug is compressed radially upon insertion into the defect.
An implantable prosthesis for repairing or reconstructing a tissue or muscle wall defect, comprising:
- a flexible conical outer plug formed of a biologically compatible, implantable fabric having openings therein for tissue ingrowth, including an atraumatically configured end, an open base and a cavity therebetween, said conical outer plug being radially compressible upon insertion into the defect into a configuration which approximates the shape of the defect and including a pleated surface which allows said outer plug to conform to irregularities in the tissue or muscle wall defining the defect;
- and
- at least two flexible conical inner filler plugs, each formed of a biologically compatible, implantable fabric having openings therein for tissue ingrowth, said at least two flexible conical inner filler plugs including a pleated surface in an uncompressed configuration and being positioned within said outer plug cavity, whereby said at least two flexible conical inner filler plugs impart bulk to, and stiffen, said implantable prosthesis when said flexible conical outer plug is compressed upon insertion into the defect.
