Abstract
A system for providing baroreflex stimulation comprises a sensor to detect a parameter and provide a signal indicative of the parameter and a baroreflex stimulator. The baroreflex stimulator includes a driver to provide a control signal adapted to deliver a baroreflex therapy and a controller to receive the signal indicative of the parameter and modulate the control signal based on the signal indicative of the parameter to change the baroreflex therapy from a first baroreflex therapy to a second baroreflex therapy.
Claims15
A method for operating an implantable medical device, the medical device having a control system contained within an implantable housing, and an electrode coupled to the control system and implanted in contact with a blood vessel, the method comprising:
- performing a first therapy using the medical device according to a program stored in the control system, including delivering a first baroreflex stimulation signal through the electrode to stimulate a baroreceptor within a wall of the blood vessel, the first therapy programmed to treat a physiological condition through a baroreflex response;
- and
- in response to detecting a predetermined threshold value, automatically performing a second therapy using the medical device according to a program stored in the control system, including delivering a second baroreflex stimulation signal through the electrode to stimulate the baroreceptor, the second therapy programmed to treat the physiological condition through a baroreflex response, wherein the second therapy is different from the first therapy.
