Baroreflex activation for sedation and sleep
First Claim
1. A method for baroreceptor stimulation via an intra-to-extravascular approach, the method comprising:
- intravascularly advancing at least one electrode to a treatment site within vasculature of a patient;
passing a portion of the electrode through at least a portion of a wall of the vasculature to position the electrode at an extravascular location via an intra-to-extravascular approach; and
extravascularly delivering an electric field via the electrode to stimulate a baroreceptor.

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.

17. A method for baroreceptor stimulation via an intra-to-extravascular approach, the method comprising:
-
causing a pulse generator to be manufactured and made available to a user; causing at least one electrode to be manufactured and made available to the user, the electrode electrically coupleable to the pulse generator; and providing instructions to the user, comprising; implanting the pulse generator within a patient; intravascularly advancing the at least one electrode to a treatment site within vasculature of the patient; passing a portion of the electrode through at least a portion of a wall of the vasculature to position the electrode at an extravascular location via an intra-to-extravascular approach; and causing an electric field to be extravascularly delivered via the electrode to stimulate a baroreceptor.
