Endovascular catheters and methods for carotid body ablation
First Claim
Patent Images
1. An ablation method for ablating target tissue within a carotid septum of a patient, the method comprising:
- endovascularly positioning a distal region of an ablation catheter proximate a carotid septum;
deploying an ablation needle from an ablation catheter, piercing tissue with the needle, and positioning the needle into the carotid septum; and
delivering an ablation agent through the ablation needle and into the carotid septum, to ablate tissue within the carotid septum and treat at least one of hypertension, heart failure, and central sleep apnea.

Abstract
Systems, devices, and methods for treating a patient having a sympathetically mediated disease associated at least in part with augmented peripheral chemoreflex or heightened sympathetic activation. The treatments include ablating one or more peripheral chemoreceptors or associated afferent nerves to reduce or remove afferent neural signals from the peripheral chemoreceptor.
