Abstract
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.
Claims9
A carotid septum ablation apparatus, comprising:
- an elongate shaft, an expandable balloon secured to a distal region of the elongate shaft, a deployable arm adapted to branch from the elongate shaft and extend radially away from a longitudinal axis of the elongate shaft, the expandable balloon adapted to be in fluid communication with an inflation fluid source;
- and an elongate member comprising a cryo-ablation member disposed at a distal end of the elongate member, the cryo-ablation member adapted to be in thermal communication with a cryo fluid source to apply thermal energy, the cryo fluid source and the inflation fluid source being different sources, wherein the elongate member and the elongate shaft are adapted so that the elongate member extends radially away from the longitudinal axis of the elongate shaft distal to where the deployable arm branches from the elongate shaft.
