Method and system for implantable pressure transducer for regulating blood pressure
First Claim
1. A method of initiating a baroreflex response, the method comprising:
- accessing a first blood vessel having a region capable of initiating the 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;
wherein the first blood vessel and the second blood vessel are both arteries.

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.

7. A method of initiating a baroreflex response, the method comprising:
-
providing a control unit and at least one apparatus adapted to be implanted in a patient; and providing instructions for implanting the at least one apparatus including; 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; wherein the first blood vessel and the second blood vessel are both arteries. - View Dependent Claims (8, 9, 10, 11, 12)
