Mediguide-enabled renal denervation system for ensuring wall contact and mapping lesion locations

摘要

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.

1. 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, wherein the ablation element includes a diffuser and an optical fiber having a proximal end and a distal end, the optical fiber being disposed within the elongated body and extending longitudinally therethrough, the proximal end of the optical fiber being optically coupleable to a light source, the diffuser being coupled to the distal end of the optical fiber and configured to focus energy from the light source on target tissue of a blood vessel to ablate the target tissue; and at least one localization sensor disposed adjacent the at least one ablation element on the body and configured to interact with a magnetic field.
