DEVICE AND METHOD FOR TREATING CARDIAC DISORDERS BY MODULATING AUTONOMIC RESPONSE

摘要

A method and device for modulating the autonomic nervous system adjacent a pericardial space to treat cardiac arrhythmia includes a treatment source (12) arranged to supply a treatment medium (14), a catheter (16) having an end (20) sized for insertion into the pericardial space, a medium delivery assembly (22) having a distal end (26) arranged to be positioned by the catheter into the pericardium, with the distal end of the delivery assembly comprising a delivery tip (30) arranged to extend away from the distal end of the catheter into the pericardial space. A connector (32) operatively couples the delivery tip of the medium delivery assembly to the treatment source, and the delivery tip of the medium delivery assembly including a plurality of delivery points for delivering the treatment medium at a plurality of treatment areas within the pericardial space. The device performs modulation or ablation of the autonomic nervous system at selected treatment areas within the pericardium.
