Abstract
An implantable prosthesis for occluding the opening of a muscle or tissue defect. The implant is laparoscopically deliverable with a system for loading and delivering the prosthesis through a trocar cannula. The prosthesis includes an implantable material with a body portion sufficient to extend across and occlude a defect opening. Antimigration barbs extend from the implantable material to prevent migration of the prosthesis after implantation. A semi-rigid ring may be attached to the material for supporting the body portion. The barbs may be located on the ring. The implantable prosthesis may be provided with a sufficient hoop strength to prevent the body portion from collapsing into the defect opening.
Claims40
An implantable prosthesis for occluding the opening of a muscle or tissue defect, comprising:
- a flexible, generally flat patch of implantable material including a body portion constructed and arranged to cover the defect opening when positioned thereagainst;
- and
- a plurality of barbs disposed on said patch of implantable material and extending at spaced locations from said patch of implantable material, wherein said plurality of spaced barbs prevent migration of said implantable prosthesis after implantation.
An implantable prosthesis for occluding the opening of a muscle or tissue defect, comprising:
- an implantable material including a body portion constructed and arranged to cover the defect opening when positioned thereagainst;
- an implantable base attached to and circumscribing said body portion, said implantable base being constructed and arranged to urge said body portion toward a non-tubular configuration;
- and
- a plurality of barbs disposed at spaced locations on said implantable base and extending from said implantable base, wherein said plurality of spaced barbs prevent migration of said implantable prosthesis after implantation.
An implantable prosthesis for occluding the opening of a muscle or tissue defect, comprising:
- a flexible, generally flat patch of implantable material including a body portion constructed and arranged to cover the defect opening when positioned thereagainst;
- and
- a plurality of anchors disposed on said patch of implantable material and extending at spaced locations from said patch of implantable material, wherein said plurality of spaced anchors prevent migration of said implantable prosthesis after implantation.
An implantable prosthesis for occluding the opening of a muscle or tissue defect, comprising:
- an implantable material including a body portion constructed and arranged to cover the defect opening when positioned thereagainst;
- an implantable base attached to and circumscribing said body portion, said implantable base being constructed and arranged to urge said body portion toward a non-tubular configuration;
- and
- a plurality of anchors disposed at spaced locations on said implantable base and extending from said implantable base, wherein said plurality of spaced anchors prevent migration of said implantable prosthesis after implantation.
An implantable prosthesis for occluding the opening of a muscle or tissue defect, comprising:
- a flexible, generally flat patch of implantable material including a body portion constructed and arranged to cover the defect opening when positioned thereagainst;
- and
- means, disposed on said patch of implantable material, for preventing migration of said implantable prosthesis after implantation.
An implantable prosthesis for occluding the opening of a muscle or tissue defect, comprising:
- an implantable material including a body portion constructed and arranged to cover the defect opening when positioned thereagainst;
- means for urging said body portion toward a non-tubular configuration;
- and
- means, disposed on said means for urging, for preventing migration of said implantable prosthesis after implantation.
