Abstract
Abstract A catheter for ablating and/or mapping tissue on the inner wall of a blood vessel, including a body portion and a tip portion having a proximal section and a distal section, the proximal section including a proximal ablation electrode and a proximal mapping electrode and the distal section including a distal ablation electrode and a distal mapping electrode, wherein the tip portion is deflectable from a first, generally straight, configuration in which the proximal and distal sections are substantially co-linear to a second, J-shaped, configuration in which the proximal and distal sections are generally parallel with a separation therebetween substantially corresponding to the inside diameter of the blood vessel.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
109 words
A catheter for ablating and/or mapping tissue on the inner wall of a blood vessel comprising: a body portion; and a tip portion having a proximal section and a distal section, the proximal section including a proximal ablation electrode and a proximal mapping electrode and the distal section including a distal ablation electrode and a distal mapping electrode, wherein said tip portion is deflectable from a first, generally straight, configuration in which the proximal and distal sections are substantially co-linear to a second, J-shaped, configuration in which the proximal and distal sections are generally parallel with a separation therebetween substantially corresponding to the inside diameter of said blood vessel.
Claim 2
Dependent Claim
109 words
A catheter for ablating and/or mapping tissue on the inner wall of a blood vessel comprising: a body portion; and a tip portion having a proximal section and a distal section, the proximal section including a proximal ablation electrode and a proximal mapping electrode and the distal section including a distal ablation electrode and a distal mapping electrode, wherein said tip portion is deflectable from a first, generally straight, configuration in which the proximal and distal sections are substantially co-linear to a second, J-shaped, configuration in which the proximal and distal sections are generally parallel with a separation therebetween substantially corresponding to the inside diameter of said blood vessel.
Claim 3
Dependent Claim
14 words
A catheter according to claim 1 wherein said blood vessel is a pulmonary vein.
Claim 4
Dependent Claim
32 words
A catheter according to claim 1 and further comprising a proximal temperature sensor thermally associated with the proximal ablation electrode and a distal temperature sensors thermally associated with the distal ablation electrode.
Claim 5
Dependent Claim
14 words
A catheter according to claim 3 wherein said blood vessel is a pulmonary vein.
Claim 6
Independent Claim
146 words
A method for ablating tissue on the inner wall of a blood vessel comprising the steps of: inserting into said blood vessel a catheter tip portion having a proximal section and a distal section, the proximal section including a proximal ablation electrode and a proximal mapping electrode and the distal section including a distal ablation electrode and a distal mapping electrode, said tip portion having a J-shaped configuration in which the proximal and distal sections are generally parallel and engage first and second, diametrically opposite, regions of said inner wall of the blood vessel; monitoring the output of at least one of the proximal and distal mapping electrodes to detect a source of aberrant heart activity on said inner wall; and selectively activating at least one of the proximal and distal ablation electrodes to ablate tissue in at least one of said first and second regions.
Claim 7
Independent Claim
146 words
A method for ablating tissue on the inner wall of a blood vessel comprising the steps of: inserting into said blood vessel a catheter tip portion having a proximal section and a distal section, the proximal section including a proximal ablation electrode and a proximal mapping electrode and the distal section including a distal ablation electrode and a distal mapping electrode, said tip portion having a J-shaped configuration in which the proximal and distal sections are generally parallel and engage first and second, diametrically opposite, regions of said inner wall of the blood vessel; monitoring the output of at least one of the proximal and distal mapping electrodes to detect a source of aberrant heart activity on said inner wall; and selectively activating at least one of the proximal and distal ablation electrodes to ablate tissue in at least one of said first and second regions.
Claim 8
Dependent Claim
14 words
A method according to claim 5 wherein said blood vessel is a pulmonary vein.
Claim 9
Dependent Claim
78 words
A method according to claim 5 and further comprising, after the step of activating at least one of said proximal and distal electrodes to ablate tissue in at least one said first and second regions, a step of rotating said catheter tip about a longitudinal axis such that said proximal and distal sections engage third and fourth, diametrically opposite, regions of said inner wall, and subsequently ablating tissue in at least one of said third and fourth regions.
Claim 10
Dependent Claim
14 words
A method according to claim 7 wherein said blood vessel is a pulmonary vein.
