METHODS AND APPARATUSES FOR TREATING AUTO-IMMUNE DISEASES BY ABLATIVE NEUROMODULATION

摘要

The present invention, in some embodiments thereof, relates to intravascular neural ablation and, more particularly, but not exclusively, to tools and methodologies for treating systemic nerve hyperactivity through splenic and/or carotid denervation. Devices are disclosed for performing ablation and protecting a patient from formation of embolisms. Furthermore a branching ablation unit is disclosed.

主权项

1. A tool for ablation of tissue in a living patient comprising:
a plurality of ablation electrodes; a basket mounted axially to a shaft, said basket having:
a radially contracted configuration wherein supports of said basket are oriented along an axis of said basket for fitting into a channel of a catheter, a distal end of said catheter fitting into a lumen of the living patient; anda radially spread configuration wherein said supports are spread radially away from said axis for holding said plurality of electrodes against an inner wall of said lumen; a cup shaped embolic trap configured to spread to block said lumen to transport of emboli, said embolic trap spreading radially around an apex located along an axis of said basket and distal to said basket; and a manipulation apparatus configured to be accessible from the proximal end of said catheter said manipulation apparatus configured for:
reversibly extending and retrieving said shaft including said basket and said plurality of electrodes and said embolic trap through a distal opening of said catheter; andreversibly switching said basket between said radially contracted configuration and said radially spread configuration.
