AUTOMATIC BAROREFLEX MODULATION RESPONSIVE TO ADVERSE EVENT
First Claim
Patent Images
1. A baroreflex stimulator, comprising:
- an electrode adapted to be positioned proximate to sensory nerve endings for a receptor sensitive to pressure;
an implantable pulse generator configured to provide a baroreflex stimulation signal through the electrode to the sensory nerve endings to control blood pressure through a baroreflex response that reduces coronary vascular resistance and increases blood flow;
means for receiving a signal regarding a detected adverse event; and
means for controlling blood pressure using the implantable device and the electrode. wherein the means for controlling blood pressure includes;
means for performing a first baroreflex therapy when the adverse event is not detected, wherein the means for performing the first baroreflex therapy includes means for delivering a first baroreflex stimulation signal through the electrode to the sensory nerve endings; and
means for adjusting blood pressure for the predetermined adverse event when the adverse event is detected, wherein the means for adjusting blood pressure includes means for automatically performing a second baroreflex therapy when the adverse event is detected, and wherein the means for automatically performing the second baroreflex therapy includes means for delivering a second baroreflex stimulation signal through the electrode to the sensory nerve endings.

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.

15. A system for providing baroreflex stimulation, comprising:
-
an adverse event detector to sense a predetermined adverse event and provide a signal indicative of the adverse event; and a baroreflex stimulator, including; a pulse generator to provide a baroreflex stimulation signal for baroreflex therapy; and a modulator to receive the signal indicative of the adverse event and to modulate the baroreflex stimulation signal based on the signal indicative of the adverse event, wherein the pulse generator and modulator are configured to cooperate to adjust blood pressure for the adverse event by providing a first baroreflex therapy when the adverse event is not detected and providing and a second baroreflex therapy when the adverse event is detected, wherein the baroreflex stimulation signal for the first baroreflex therapy is different than the baroreflex therapy for the second baroreflex therapy. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
