1. A method for repairing a defect in tissue comprising the steps of:
- a) placing a prosthetic over a tissue defect and against surrounding tissue;
b) providing an ultrasonic surgical device having an end effector comprising a first surface and a second surface, said ultrasonic surgical device applying ultrasonic energy to said end effector, said ultrasonic energy applied to said first surface of said end effector being at a first ultrasonic energy intensity level and said ultrasonic energy applied to said second surface of said end effector being at a second ultrasonic energy intensity level wherein said second ultrasonic energy intensity level is greater than said first ultrasonic energy intensity level;
c) embedding a prosthetic into surrounding tissue with said first surface of said end effector by a first application of pressure and ultrasonic energy to said prosthetic and said surrounding tissue on at least one location on said prosthetic and said surrounding tissue by applying said ultrasonic energy to said first surface of said end effector at said first ultrasonic energy intensity level; and
d) welding said embedded prosthetic into said surrounding tissue with said second surface of said end effector by a second application of pressure and ultrasonic energy on said at least one location by applying said ultrasonic energy to said second surface of said end effector at said greater second ultrasonic energy intensity level.

Abstract
A method of repairing a defect in tissue includes the steps of placing a prosthetic over a tissue defect and against surrounding tissue. The prosthetic is then embedded into the surrounding tissue by an application of pressure and ultrasonic energy to the prosthetic and the surrounding tissue on at least one location on the prosthetic and surrounding tissue. The embedded prosthetic is then welded into surrounding tissue by an application of pressure and ultrasonic energy on the same location. The second application of energy is at a different energy intensity than the first application of energy.
