Devices and methods for electrode implantation
First Claim
1. A system for implantation of a medical lead configured to deliver electrical stimulation to nerve tissue located adjacent a blood vessel, the system comprising:
- an electrode;
a means for delivering the electrode through a lumen of the blood vessel;
a means for determining a suitable implant location for the electrode proximate the nerve tissue; and
a means for deploying the electrode through a wall of the blood vessel, so as to position the electrode outside of the blood vessel proximate the nerve tissue,wherein the means for determining is configured to detect one or more physiological signals from the patient in response to a baroreceptor activation signal delivered through the electrode.

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.

11. A method comprising:
-
delivering a lead through a lumen of a blood vessel to a location proximate a target nerve tissue site outside the blood vessel, the lead including an electrode at a distal end; determining a suitable implant location for the electrode; advancing the lead from within the lumen such that the electrode passes through a wall of the blood vessel; and determining a suitable implant location for the electrode, proximate the nerve tissue, wherein determining a suitable implant location for the electrode comprises a mapping procedure including; delivering a baroreceptor activation signal through the electrode from a plurality of locations within the blood vessel; and measuring a patient response to each baroreceptor activation signal. - View Dependent Claims (12, 13, 14)
