METHOD AND SYSTEM FOR IMPLANTABLE PRESSURE TRANSDUCER FOR REGULATING BLOOD PRESSURE
First Claim
1. An apparatus for an implantable medical device that monitors at least one physiologic parameter and selectively stimulates a baroreflex response, the apparatus comprising:
- a transducer adapted to measure the at least one physiologic parameter from within a blood vessel;
an electrode adapted to stimulate the baroreflex response;
an elongate body having an at least one distal end adapted to be positioned within the blood vessel with the transducer positioned proximate the at least one distal end;
a first conductor in the elongate body operably coupled to the transducer to relay a signal representative of the physiologic parameter from the transducer; and
a second conductor in the elongate body adapted to relay a therapy signal to the electrode.

Abstract
An apparatus and a system can chronically and automatically measure a physiologic parameter associated with the high pressure side of the vasculature and/or regulate blood pressure based upon the measured parameter. The apparatus may be made up of a transducer, a baroreflex activation device having one or more electrodes, and a lead having two or more conductors. The system can measure a physiologic parameter and selectively administer a therapy, such as, for example, electro-stimulation of baroreceptors, based upon the measurement. The transducer for measuring the physiologic parameter can be chronically implanted in the high-pressure side of the vasculature. The implantation method may include intravascularly positioning the transducer in the external carotid artery in such a way that the transducer is first introduced into the arterial vasculature through the superior thyroid artery.

10. A medical system for selectively stimulating a baroreflex response in response to a measurement of a physiologic parameter, the medical system comprising:
-
at least one apparatus having an elongate body with at least one distal end and including a transducer adapted to measure the physiologic parameter from within a blood vessel and generate a sensor signal representative of the physiologic parameter and an electrode adapted to receive a therapy signal and stimulate the baroreflex response; and a control unit that communicates signals with the transducer and the electrode to provide a baroreflex activation therapy. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A method of initiating a baroreflex response, the method comprising:
-
accessing a first blood vessel having a region capable of initiating a baroreflex response; creating an opening in a second blood vessel proximate the region and branching from the first blood vessel; inserting a transducer operably carried by a distal end of an apparatus into the opening in the second blood vessel; positioning an electrode operably carried by the distal end of the apparatus proximate the region of the first blood vessel; and operably connecting the transducer and the electrode to a control unit; and causing the control unit to selectively generate a therapy signal delivered to the electrode in response to a sensor signal representative of the physiologic parameter measured by the transducer. - View Dependent Claims (20, 21, 22, 23, 24)
