An implantable prosthesis for repairing an anatomical defect, such as a tissue or muscle wall hernia, including an umbilical hernia, and for preventing the occurrence of a hernia at a small opening or weakness in a tissue or muscle wall, such as at a puncture tract opening remaining after completion
An implantable prosthesis for repairing an anatomical defect, such as a tissue or muscle wall hernia, including an umbilical hernia, and for preventing the occurrence of a hernia at a small opening or weakness in a tissue or muscle wall, such as at a puncture tract opening remaining after completion of a laparoscopic procedure. The prosthesis includes a patch for covering or extending across the opening or weakness. At least one tether, such as a strap, extends from the patch and may be manipulated to position and/or to secure the patch relative to the opening or weakness in the tissue or muscle wall. The tether may be configured to extend through the defect and outside a patient's body for positioning and/or manipulating the patch from a location outside the body. A support member may be arranged in or on the patch to help deploy the patch at the surgical site and/or help inhibit collapse or buckling of the patch.
