Soft tissue defect repair device
View Patent ↗An inguinal hernia repair device in the form of an implantable plug that is affixed at one end to the center region of a sheet of implantable material. The plug takes the form of a plurality of hollow members, arranged so as to be in substantially parallel relationship when implanted into a defect. The hollow members are preferably tubular members and are preferably bundled together by various means, such as bonding or wrapping a band or strand about the plurality of hollow members to maintain them in adjacent and contacting relationship during insertion into a defect. The device is provided with a base member for anchorage made of a composite material having a non-bioabsorable component and a bioabsorbable component.
1. An implantable tissue repair device comprising:
a plurality of discrete tubes each having a length;
wherein each discrete tube has two ends and at least one of said ends is open;
wherein each discrete tube is made of a bioabsorbable polymeric material;
wherein each discrete tube is attached to a substantially planar base member at a fold along a mid-point of said discrete tube; and
wherein said substantially planar base member is a composite of a non-bioabsorbable polymeric material placed within a bioabsorbable polymeric material in the form of a self-cohering web.
2. The implantable tissue repair device of claim 1 wherein said self-cohering web includes a co-polymer of polyglycolic acid and trimethylene carbonate (PGA:TMC).
3. The implantable tissue repair device of 1 wherein said non-bioabsorbable polymeric includes porous expanded polytetrafluoroethylene (ePTFE).
4. An implantable tissue repair device comprising:
a plurality of discrete tubes each having a length;
wherein each discrete tube has two ends and at least one of said ends is open;
wherein each discrete tube is made of a bioabsorbable polymeric material;
wherein each discrete tube is attached to a substantially planar base member at a fold along a mid-point of said discrete tube; and
wherein said substantially planar base member is a composite of a non-bioabsorbable polymeric material placed between at least two layers of a bioabsorbable polymeric material in the form of a self-cohering web.
5. The implantable tissue repair device of claim 4 wherein said self-cohering web includes a co-polymer of polyglycolic acid and trimethylene carbonate (PGA:TMC).
6. The implantable tissue repair device of 4 wherein said non-bioabsorbable polymeric includes porous expanded polytetrafluoroethylene (ePTFE).
