Abstract

A catheter having an extended treatment zone for cooling tissue is provided.
The catheter includes an elongate catheter body having a distal tip, and a fluid injection conduit disposed inside the catheter body defining a return lumen therein. The fluid injection conduit further defines two or more injection orifices including a first distal orifice near the distal tip, and a second orifice longitudinally offset along the fluid injection conduit to be less proximate the distal tip than the first orifice. Fluid cryogen flowing through the orifices creates an extended tissue cooling contour about the distal end portion of the catheter. At least one ECG ring electrode is provided about the catheter body near the second orifice. The catheter may thus provide for electrocardiographic mapping of tissue nodes lying transversely between the distal tip and the ECG ring electrode.

Claims (21)

1. A tissue mapping and cryotreatment catheter, comprising:
an elongate catheter body having a distal tip, a fluid injection conduit disposed inside the catheter body and defining a return lumen therein, the fluid injection conduit having a distal end portion, the distal end portion defining two or more injection orifices including a first orifice and a second orifice, the first orifice being proximate the distal tip, the second orifice being longitudinally offset along the fluid injection conduit to be less proximate the distal tip than the first orifice.
at least one electrocardiogram lead disposed on the catheter body proximate the distal tip, the at least one electrode being longitudinally offset from the distal tip to be proximate the second orifice, and a thermally transmissive and electrically insulating first body section disposed on the catheter body and longitudinally offset along the catheter body from the distal tip, the first body section surrounding the at least one electrocardiogram lead such that the distal tip is electrically isolated from the at least one electrocardiogram lead.
2. Cancelled.
3. The catheter of claim 1, wherein the distal tip is a second electrocardiogram lead.
4. Cancelled.
5. The catheter of claim 1, wherein the first body section includes an outer surface and the at least one electrocardiogram lead is a circumferential ring disposed about the outer surface of the first body section of the catheter body.
6. The catheter of claim 1, further comprising:
a thermally conductive second body section disposed on the catheter body adjacent the first body section and longitudinally offset along the catheter body from the distal tip to be less proximate the distal tip than the first body section.
7. The catheter of claim 1, further comprising:
a thermally conductive section disposed on the catheter body proximate the distal tip.
8. The catheter of claim 7, wherein the distal end portion of the fluid injection conduit defines first, second and third orifices having first, second, and third normal axes, respectively, the first normal axis being substantially parallel to the longitudinal axis, and the second and third normal axes being substantially perpendicular to the longitudinal axis.
9. The catheter of claim 8, wherein second and third normal axes are coincident lines in opposite direction to one another.
10. The catheter of claim 8, wherein the distal end portion of the fluid injection conduit defines a separation length along the longitudinal axis between the first orifice and the second orifice, the separation length being in a range between 1 mm and 50 mm.
11. Cancelled.
12. Cancelled.
13. Cancelled.
14. Cancelled.
15. The catheter of claim 1, further comprising:
an electrically conductive wire coupled to the at least one electrocardiogram lead.

17. The cryogenic catheter according to claim 16, further including a plurality of fluid outlets arranged in special relation with the plurality of thermally-transmissive segments.
18. The cryogenic catheter according to claim 7 wherein the thermally conductive section defines:

an elongated thermally-transmissive region defining a substantially longitudinal axis therethrough; and a plurality of cryogenic fluid dispensing lumens substantially traversing the thermally-conductive section and axially staggered along the longitudinal axis, wherein the plurality of cryogenic dispensing lumens include at least one fluid outlet directing a portion of cryogenic fluid away from the longitudinal axis.
19. The cryogenic catheter according to claim 18, wherein the cryogenic fluid dispensing lumens are radially staggered about the longitudinal axis.
20. The cryogenic catheter according to claim 18, wherein the cryogenic fluid dispensing lumens further comprise at least one distal fluid outlet located at a distal end of the cryogenic dispensing lumens.
21. The cryogenic catheter according to claim 1, wherein the thermally transmissive and electrically insulating first body section is constructed from boron nitride.
