Abstract
A device for cryosurgical ablation. A tip has a thermally transmissive region (16) along a length thereof in which the thermally transmissive region is operable at a temperature sufficient to cryosurgically ablate tissue in contact therewith. A plurality of cryosurgical fluid injection lumens (30a, 30b) each have a first end positioned within the tip at a different point along the length of the thermally transmissive region (16). Each of the first ends is arranged to cool overlapping respective portions along the length of the thermally transmissive region when the cryogenic fluid is ejected from the plurality of cryogenic fluid injection means.
Claims
1. (Amended) A device for cooling tissue, comprising: a tip having a thermally transmissive region along a length thereof, the thermally transmissive region being operable at a temperature sufficient to cool tissue in contact therewith; a plurality of fluid injection lumens, each ofthe plurality of injection lumens having a first end positioned within the tip at a different point along the length ofthe thermally transmissive region, each ofthe first ends being arranged to cool overlapping respective portions along the length ofthe thermally transmissive region when fluid is ejected from the plurality of fluid injection lumenSi wherein each ofthe plurality of fluid injection lumens further comprises a second end opposite the first end, and wherein the device further comprises a plurality of valves, each ofthe plurality of valves having an output in fluid communication with the second end of a corresponding fluid injection lumen.
2. (CANCELLED)
3. (Amended) The device according to Claim 1, wherein the plurality of valves are electrically actuable.
4. (Amended) The device according to Claim 1, wherein the device further comprises a handle having an inner volume and wherein each ofthe plurality of valves processor is positioned within the inner volume.
5. (Amended) The device according to Claim 1, further comprising a fluid distributor, the fluid distributor having: an input for receiving a flow of cryogenic fluid; and a plurality of outputs in fluid communication with a respective valve, the fluid distributor receiving the flow of fluid and substantially evenly distributing the flow of fluid to each ofthe plurality of valves.
6. The device according to Claim 5, wherein the device further comprises a handle having an inner volume and wherein the fluid distributor is positioned within the inner volume.
7. (Amended) The device according to Claim 1, wherein the plurality of valves are individually sequentially actuable.
8. The device according to Claim 1 , wherein each of the plurality of fluid injection lumens further comprises a second end opposite the first end, and wherein the device further comprises a valve assembly having: a plurality of electrically actuable valves, each ofthe plurality of electrically actuable valves having an output in fluid communication with the second end of a corresponding fluid injection lumen; and a valve processor, the valve processor receiving at least one electronic valve actuation signal and controlling the actuation ofthe plurality of valves in accordance with the received at least one electronic valve actuation signal.
9. The device according to Claim 8, wherein the plurality of electrically actuable valves are piezo-electric valves.
10. The device according to Claim 8, wherein the device further comprises a handle having an inner volume and wherein the valve processor is positioned within the inner volume.
11. The device according to Claim 8, further comprising a fluid distributor, the fluid distributor having: an input for receiving a flow of fluid; and a plurality of outputs in fluid communication with a respective valve within the valve assembly, the fluid distributor receiving the flow of fluid and substantially evenly distributing the flow of fluid to each ofthe plurality of valves within the valve assembly.
