Apparatus and methods for feedback-based nerve modulation
First Claim
1. A hypertension therapy device for affecting blood pressure, the hypertension therapy device comprising:
- a housing configured for location external to a body of a subject;
a first antenna configured to communicate with a second antenna associated with a circuit implanted in a blood vessel of the subject within proximity to at least one of a renal nerve, a baroreceptor, and a glossopharyngeal nerve, wherein the circuit is in electrical communication with at least one electrode;
a feedback circuit associated with the housing and configured to communicate with the first antenna;
at least one processor associated with the housing and further configured to;
communicate with the circuit through the first antenna;
receive a physiological signal from the subject;
send a control signal to the implanted circuit in response to the physiological signal, wherein the control signal is predetermined to modulate nerve tissue to affect blood pressure;
apply a sub-modulation control signal to the first antenna, the sub-modulation control signal inducing a secondary signal at the second antenna, the secondary signal in turn inducing a coupled signal at the first antenna;
receive, from the feedback circuit, the coupled signal generated by the first antenna; and
adjust the control signal based on the coupled signal received from the feedback circuit.

Abstract
A device according to some embodiments may include a housing configured for location external to a body of a subject. The device may also include at least one processor associated with the housing and configured to communicate with a circuit implanted in the subject within proximity to a tongue of the subject, wherein the circuit is in electrical communication with at least one electrode, receive a physiological signal from the subject via the circuit, and send a control signal to the implanted circuit in response to the physiological signal, wherein the control signal is predetermined to activate neuromuscular tissue within the tongue.
