Abstract
The invention concerns a device for the high-frequency catheter ablation of endomyocardial tissue, said device including an ablation catheter and an associated connection to a high-frequency generator or high-frequency ablation apparatus. According to the invention, in order to facilitate catheter ablation and reduce the amount of time and treatment necessary therefor, a catheter arrangement including a plurality of electrodes is provided, wherein a plurality of electrodes can be controlled selectively in order to coagulate preferably endomyocardial tissue.
Claims16
A high-frequency ablation catheter for linear endomyocardial catheter ablation, comprising a plurality of electrodes separated from one another by isolating zones, said electrodes being selectively controllable to coagulate tissue;
- one or more thermal sensors assigned to said electrodes in a selected manner such that the operating temperature of one or more of the electrodes can be detected;
- and a control unit programmed to operate in one of a plurality of operating states based on the selected assignment of thermal sensors to control delivery of ablation energy to the respective electrodes.
A high-frequency ablation catheter, comprising a plurality of electrodes separated from one another by isolating zones, said electrodes being selectively controllable to coagulate tissue;
- one or more thermal sensors assigned to said electrodes in a selected manner such that the operating temperature of one or more of the electrodes can be detected;
- and a control unit programmed to deliver ablation energy to the respective electrodes, wherein the ablation energy is diverted to a load when not required by one of the electrodes.
A method of performing an ablation procedure with a catheter having a plurality of electrodes separated from one another by isolating zones, the method comprising the steps of:
- sequentially delivering ablation energy to the electrodes;
- monitoring one or more conditions at one or more of the electrodes;
- and
- diverting the ablation energy to a load when one or more of the monitored conditions exceeds a preselected threshold.
