First Claim
Patent Images
1. A baroreflex therapy system for providing temporary and chronic treatments to a patient, comprising:
- an implantable baroreflex activation device having at least one electrode and including a lead with a first end coupled to the at least one electrode and a second end with a connector;
an external controller, including a pulse generator adapted to deliver baroreflex therapy pulses to the implantable baroreflex activation device via a cable having one end adapted to releasably couple with the connector of the lead of the implantable baroreflex activation device, the controller adapted to activate, deactivate or otherwise modulate the implantable baroreflex activation device based on a signal received from a sensor; and
an implantable baroreflex activation therapy pulse generator including a header adapted to connect with the connector,the system being configured to determine based on a first temporary period whether the patient is responding to the baroreflex therapy as generated by the external controller, and in response, provide an indication that the implantable baroreflex activation therapy pulse generator should be implanted and connected to the implantable baroreflex activation device to provide baroreflex for a second chronic period.

5. A method of treating a patient, comprising:
-
providing a baroreflex activation device having at least one electrode; providing an external controller, including a pulse generator and a junction; providing a lead coupled to the baroreflex activation device, the lead including a distal end configured to be releasably coupled to the junction; providing instructions to treat the patient, including; implanting the baroreflex activation device proximate a baroreceptor in a vascular wall; positioning the distal end of the lead through the skin of the patient such that the distal end of the lead is outside the body of the patient; releasably coupling the lead to the controller; and activating, deactivating, or otherwise modulating the at least one electrode with the controller to cause a baroreflex in the patient. - View Dependent Claims (6, 7, 8, 9, 10)
