Implantable prosthesis

An implantable prosthesis for repairing a defect in a muscle or tissue wall, the prosthesis comprising:

• a body of biologically compatible mesh material having a preformed three-dimensional contoured shape that independently assumes a curved shape configured to conform to the muscle or tissue wall, the body having a tensile strength of 12.6 lbs to 17.1 lbs in the machine direction and 31.4 lbs to 44.9 lbs in the cross direction.

An implantable prosthesis for repairing a defect in a muscle or tissue wall, the prosthesis comprising:

• a body of biologically compatible mesh material having a preformed three-dimensional contoured shape that independently assumes a curved shape configured to conform to the muscle or tissue wall, the body having a tear resistance of 7.8 lbs to 12.3 lbs in the machine direction and 7.7 lbs to 12.9 lbs in the cross direction.

An implantable prosthesis for repairing a defect in a muscle or tissue wall, the prosthesis comprising:

• a body of biologically compatible mesh material having a preformed three-dimensional contoured shape that independently assumes a curved shape configured to conform to the muscle or tissue wall, the body having an elongation at break of 100.3% to 133.7% in the machine direction and 52.6% to 66.4% in the cross direction.

An implantable prosthesis for repairing a defect in a muscle or tissue wall, the prosthesis comprising:

• a body of biologically compatible mesh material having a preformed three-dimensional contoured shape that independently assumes a curved shape configured to conform to the muscle or tissue wall, the body having a ball burst strength of 45 lbs to 52 lbs, a tensile strength of 12.6 lbs to 17.1 lbs in the machine direction and 31.4 lbs to 44.9 lbs in the cross direction, a tear resistance of 7.8 lbs to 12.3 lbs in the machine direction and 7.7 lbs to 12.9 lbs in the cross direction and an elongation at break of 100.3% to 133.7% in the machine direction and 52.6% to 66.4% in the cross direction.
