ELECTRICAL RENAL AUTONOMIC BLOCKADE
First Claim
1. A method comprising:
- sensing a physiological parameter of a patient;
generating a stimulation signal with an implantable electrical stimulator based on the physiological parameter;
delivering the stimulation signal from the implantable electrical stimulator to a renal nerve of the patient;
transmitting information regarding the physiological parameter to an external device outside of the patient; and
presenting the information to a user.

Abstract
Electrical stimulation may be configured to decrease renal sympathetic activity by creating at least a partial functional conduction block in the efferent and/or afferent sympathetic nerve fibers that innervate the kidneys. An electrical stimulator may deliver a stimulation signal to a renal nerve of a patient. The stimulation signal may be a biphasic signal with a frequency of approximately 100 hertz to 20 kilohertz. In some examples, a sensor may sense a physiological parameter of the patient, and the stimulation generator may activate, deactivate, or adjust the stimulation signal based on the physiological parameter. The physiological parameter may be indicative of sympathetic activity within the patient.
