1. A tissue grasping device, comprising:
- an elongate shaft having proximal and distal ends;
first and second jaws, each pivotally coupled to the distal end of the elongate shaft and adapted to engage tissue therebetween; and
a monopolar cutting element comprising an elongate needle, the monopolar cutting element being;
(a) slidably mated to at least one of the first and second jaws,(b) flexible such that it flexes when the first and second jaws move between open and closed positions,(c) slidably movable between an extended position in which the cutting element is positioned adjacent to a distal end of the first and second jaws, and a retracted position in which the cutting element is positioned adjacent to a proximal end of the first and second jaws, and(d) adapted to couple to an energy source for delivering energy to the monopolar cutting element.

Abstract
Methods and devices are provided for delivering monopolar energy to a treatment area in order to cut and/or coagulate tissue. In one embodiment, the device can include an elongated shaft having a distal end that is mated to a cutting head. The cutting head can include opposed jaws and an active monopolar cutting element coupled to at least one of the jaws and adapted to communicate with an energy source for delivering energy to tissue grasped between the jaws. In an exemplary embodiment, the cutting element is slidably retractable relative to the jaws to cut and/or coagulate tissue engaged therebetween. Exemplary methods for cutting and/or coagulating tissue are also provided.

9. A tissue grasping device, comprising:
-
a handle having a flexible elongate shaft extending distally therefrom; opposed jaws coupled to a distal end of the flexible elongate shaft and adapted to engage tissue therebetween, wherein each opposed jaw is pivotally coupled to the distal end of the elongate shaft; and at least one monopolar cutting element comprising an elongate needle, the monopolar cutting element being; (a) slidably mated to at least one of the opposed jaws and adapted to slide relative to a longitudinal axis of the opposed jaws to cut tissue engaged between the opposed jaws, and (b) flexible such that the monopolar cutting element flexes when the opposed jaws move between open and closed positions. - View Dependent Claims (10, 11, 12, 13)

14. A method for cutting tissue, comprising:
-
positioning tissue to be cut between opposed jaws pivotally coupled to a distal end of an elongate shaft of a tissue grasping device; moving the opposed jaws to a closed position to engage the tissue disposed therebetween, wherein moving the opposed jaws comprises pivoting both jaws to the closed position; activating a monopolar energy source to deliver energy to a cutting element coupled to the opposed jaws wherein the cutting element flexes when the opposed jaws are moved to the closed position; and slidably retracting the cutting element relative to the opposed jaws to cut the tissue. - View Dependent Claims (15, 16, 17, 18, 19)
