IMPLANTABLE EXTRAVASCULAR ELECTROSTIMULATION SYSTEM HAVING A RESILIENT CUFF

摘要

A method and device for providing stimulation to an artery for purposes of eliciting a physiologic response. A cuff having at least one electrode is provided, wherein the cuff is biased to conform to at least a portion of a vascular structure to maintain an intimate vascular structure-electrode interface. The device is selectively positioned proximate the effective position for providing stimulation to the vascular structure and the cuff is enabled to biasedly conform to at least a portion of the vascular structure. The cuff comprises includes resiliency enabling substantially normal pulsatile expansion of the artery while maintaining effective artery-electrode interface.
