Device and method for ablating tissue
First Claim
1. A method of isolating an area of tissue from surrounding tissue of a patient comprising:
- providing a device comprising a device jaw having a first jaw arm including a first ablation element and a second jaw arm including a second ablation element;
placing tissue surrounding the area of tissue to be isolated within the device jaw;
supplying RF energy from an RF energy source to the first and second ablation elements; and
ablating the tissue placed within the device jaw to at least partially isolate the area of tissue.

Abstract
An electrosurgery medical device is enhanced with unique solution-assistance, and comprises, in combination, co-operating device jaws including jaw portions for manipulating tissue, and a plurality of solution infusion openings defined and spaced along each of the jaw portions, for receiving electrolytic solution and infusing the solution onto and into tissue to be manipulated, along said jaw portions. As preferred, the device further comprises at least one, and most preferably, many, longitudinal groove(s) along at least one and most preferably, both, of the jaw portions, with the solution infusion openings located in the groove or grooves. The solution is energized with RF energy and contributes to the functions and beneficial effects of the instrument. The solution exits the openings in the grooves at sufficient flow rates to separate substantially all the operative surfaces of the device from tissue, thereby substantially completely preventing adherence between the operative surfaces and tissue. The solution is further energized to a range of energy densities such that tissues to be affected are sealed against flow of blood, lymphatic fluids, air, and other bodily fluids and gases.

27. A method of ablating tissue of a patient comprising:
-
placing tissue between a first jaw and a second jaw of a device, the first and second jaws including opposed jaw portions on inner faces thereof for engaging tissue, each of the inner faces comprising an insulating portion and an ablative portion with the ablative portion being centrally located with respect to the insulating portion, the inner faces arranged on the jaws such that the inner faces are adapted to grasp tissue placed between them;
moving the first jaw and the second jaw into engagement with the tissue placed between them such that the inner faces are substantially parallel as the tissue is grasped between them; and
supplying RF energy from an RF energy source to the ablative portions of the first and second jaws to ablate the tissue grasped between the first and second jaws. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51)

52. A method of ablating tissue comprising:
-
selecting a device comprising a device jaw having a first malleable jaw arm and a second malleable jaw arm, the first malleable jaw arm includes an ablative portion;
shaping the first and second jaw arms to a specific physiological situation;
placing tissue within the device jaw;
moving the first jaw arm and the second jaw arm into engagement with the tissue placed within the device jaw such that the first and second jaw arms are substantially parallel as the tissue within the device jaw is engaged;
supplying RF energy from an RF energy source to the ablative portion; and
ablating the tissue placed within the device jaw. - View Dependent Claims (53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76)
