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.

摘要： An ablation catheter (10) includes a body (12) having a distal end (16), a hollow tip (22) attached to the distal end and an ultrasound transducer assembly positioned within the hollow tip and mounted to rotate about a longitudinal axis of the catheter body. The hollow tip includes an acoustically transparent shell, which allows acoustic energy to pass to and from the ultrasound transducer assembly, and an electrically-conductive coating on its exterior surface, which allows ablating energy to be delivered to an adjacent tissue. A plurality of ribs extend inwardly from an inner surface of the shell. A system (100) incorporating the ablation catheter and methods of using the same to ablate, image and/or monitor tissue are also disclosed.
