Abstract
Abstract A suction assisted ablation device having a support surface, suction elements disposed adjacent the support surface, at least one electrode and at least one suction conduit is provided. The device may further include fluid openings, which allow fluid to irrigate target tissue and aid in ablation. A method for ablating tissue using suction is also provided.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
102 words
A method of ablating tissue, comprising: providing a suction assisted ablation device comprising a support surface, having a first and a second face, a plurality of suction elements disposed adjacent the support surface on the first face, at least one needle electrode disposed adjacent the support surface on the first face and at least one suction conduit operatively connected with the suction elements; placing the first face of the device adjacent an area of tissue; penetrating the tissue with the needle electrode; conducting suction to the suction elements via the suction conduit; grasping the tissue with the suction; and ablating the tissue.
Claim 2
Independent Claim
102 words
A method of ablating tissue, comprising: providing a suction assisted ablation device comprising a support surface, having a first and a second face, a plurality of suction elements disposed adjacent the support surface on the first face, at least one needle electrode disposed adjacent the support surface on the first face and at least one suction conduit operatively connected with the suction elements; placing the first face of the device adjacent an area of tissue; penetrating the tissue with the needle electrode; conducting suction to the suction elements via the suction conduit; grasping the tissue with the suction; and ablating the tissue.
Claim 3
Dependent Claim
25 words
The method of claim 1 wherein placing the first face of the device is accomplished by manipulating an apparatus operatively connected to the support surface.
Claim 4
Dependent Claim
18 words
The method of claim 2 wherein manipulating the apparatus is accomplished by activating at least one pull wire.
Claim 5
Dependent Claim
15 words
The method of claim 2 wherein manipulating the apparatus is accomplished by moving a handle.
Claim 6
Dependent Claim
16 words
The method of claim 2 wherein manipulating the apparatus is accomplished by means of a catheter.
Claim 7
Dependent Claim
33 words
The method of claim 1 further comprising: measuring the temperature at a sensing element adjacent the suction element; and stopping the ablation of the tissue when the monitored temperature reaches a given level.
Claim 8
Dependent Claim
24 words
The method of claim 1 further comprising: providing at least one fluid opening in the needle electrode; and releasing fluid via the fluid opening.
Claim 9
Dependent Claim
13 words

Claim 10
Dependent Claim
13 words
The method of claim 7 wherein the fluid released is an ablative fluid.
Claim 11
Dependent Claim
12 words
The method of claim 7 wherein the fluid released includes a drug.
Claim 12
Dependent Claim
11 words
The method of claim 7 wherein the fluid released includes cells.
Claim 13
Dependent Claim
24 words
The method of claim 1 wherein the needle electrode penetrating the tissue is one of a plurality of needle electrodes on the support surface.
Claim 14
Dependent Claim
17 words
The method of claim 12 wherein the plurality of needle electrodes are arranged in a linear configuration.
Claim 15
Dependent Claim
15 words
The method of claim 13 wherein the tissue is ablated to form a linear lesion.
Claim 16
Dependent Claim
19 words
The method of claim 12 wherein some of the plurality of needle electrodes are arranged in a bioplar arrangement.
Claim 17
Dependent Claim
32 words
The method of claim 15 wherein the bipolar arrangement includes a first set of electrodes arranged in a linear configuration and a second, adjacent set of electrodes arranged in a linear configuration.
