摘要：
A method for cardiac surgical intervention relies on sealing or fusing heart valve leaflets without requiring implanted materials such as sutures or staples. The method provides a forceps having at least one shaft and an end effector assembly attached thereto. The end effector assembly includes a pair of opposing jaw members configured to move from an open, spread position to a closed, grasping position； creating at least one opening in the patient for inserting the forceps therein； inserting through the opening and manipulating jaw members of the forceps to grasp a portion of a first heart valve leaflet and a portion of a second heart valve leaflet therebetween； activating the forceps to close the jaw members about the leaflet portions under a working pressure, applying radiofrequency energy to the jaw members to seal the portion of the first heart valve leaflet to the portion of the second heart valve leaflet.
