1. A method comprising:
- arranging a generally cylindrical expandable and contractible lead member within a lumen of a blood vessel adjacent one or more baroreceptors located within a wall of the blood vessel;
temporarily deploying the cylindrical lead member within the lumen proximate the one or more baroreceptors;
energizing one or more electrodes connected to the cylindrical lead member to deliver electrical stimulation from within the blood vessel lumen to the one or more baroreceptors; and
chronically deploying the cylindrical lead member in an expanded state within the lumen relative to the one or more baroreceptors.

Abstract
Systems and methods provide baroreflex activation to treat or reduce pain and/or to cause or enhance sedation or sleep. Methods involve activating the baroreflex system to provide pain reduction, sedation, improved sleep or some combination thereof. Systems include at least one baroreflex activation device, at least one sensor for sensing physiological activity of the patient, and a processor coupled with the baroreflex activation device(s) and the sensor(s) for processing sensed data received from the sensor and for activating the baroreflex activation device. In some embodiments, the system is fully implantable within a patient, such as in an intravascular, extravascular or intramural location.

8. A method comprising:
-
placing a portion of an implantable medical lead having an electrode electrically connected thereto in an extravascular space defined by a sheath of tissue within a patient and adjacent one or more baroreceptors within the sheath of tissue within the patient; and anchoring the lead at a location proximally offset from the electrode and at least partially outside of the sheath. - View Dependent Claims (9)
