CAROTID BODY ABLATION WITH A TRANSVENOUS ULTRASOUND IMAGING AND ABLATION CATHETER

摘要

Methods and devices for assessing, and treating patients having sympathetically mediated disease, involving augmented peripheral chemoreflex and heightened sympathetic tone by reducing chemosensor input to the nervous system via carotid body ablation.

1. An ultrasound ablation catheter configured to interact with an intravascular ultrasound (“IVUS”) imaging catheter, the ultrasound ablation catheter comprising:
a distal region and a proximal region; an IVUS lumen to receive therethrough an IVUS imaging catheter extending from the proximal region to the distal region; an echolucent chamber at the distal region; and an ultrasound ablation transducer within the echolucent chamber, wherein the IVUS lumen is configured to position the IVUS imaging catheter within a direction of aim of the ultrasound ablation transducer in a deployed state and out of the direction of aim in a retracted state.
