Abstract
An ablation catheter includes an elongated body having a proximal end and a distal end. At least one ablation element is disposed on the body between the proximal end and the distal end and configured to ablate renal tissue to control hypertension. At least one localization sensor is disposed on the body and configured to interact with a magnetic field. The at least one localization sensor aids in determining an appropriate target tissue for ablation.
Claims27
An ablation catheter, comprising:
- an elongated body having a proximal end and a distal end;
- at least one ablation element disposed on the body between the proximal end and the distal end;
- and
- at least one localization sensor disposed on the body and configured to interact with a magnetic field.
An ablation catheter, comprising:
- a longitudinal rod;
- a plurality of arms disposed about the longitudinal rod, and being resiliently biased outwardly away from the longitudinal rod;
- at least one ablation element disposed on each of the arms;
- and
- at least one localization sensor disposed on at least one of the longitudinal rod and one of the plurality of arms.
A method for ablating vascular tissue, comprising:
- introducing into an artery an ablation catheter including an elongated body having a proximal end and a distal end, at least one ablation element disposed on the body between the proximal end and the distal end, and at least one localization sensor disposed on the body;
- using the at least one localization sensor to determine an appropriate target tissue for ablation;
- and
- ablating the target tissue to provide a therapeutic effect.
