Methods and devices for cryogenic carotid body ablation |
摘要 |
Methods and cryogenic 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. Some methods include advancing a cryo-ablation catheter into a patient's vasculature and ablating tissue within a carotid septum. |

1. A method for cryo-ablating target tissue within a carotid septum of a patient, the method comprising:
advancing a cryo-ablation catheter into an artery of the patient, the cryo-ablation catheter comprising first and second arms; passing the first arm into an external carotid artery of the patient and into engagement with a wall of the external carotid artery adjacent a carotid septum; passing the second arm into an internal carotid artery of the patient and into engagement with a wall of the internal carotid artery adjacent the carotid septum; and delivering a cryogen fluid through the first and second arms to ablate at least a portion of the carotid septum. |
