IMPLANTABLE DEVICE SYSTEMS FOR SLEEP APNEA
Generally discussed herein are systems, devices, and methods for providing a therapy (e.g., stimulation) and/or data signal using an implantable device. Systems, devices and methods for interacting with (e.g., communicating with, receiving power from) an external device are also provided.
1 . (canceled)
2 . A method of directing an electrical signal to a patient to treat sleep apnea, the method comprising:
programming a wearable device to transmit power to a receiver device of a percutaneously implantable device having a charge storage capacity less than a main battery of a wireless power transmission device of the wearable device; and
programming a pulse stimulation driver of the percutaneously implantable device to receive power via the receiver device; and
delivering, via at least one electrode of the percutaneously implantable device positioned to be in electrical communication with a hypoglossal nerve of the patient, an electrical signal, at least a portion of the electrical signal having a frequency in a frequency range of up to 100 kHz, to treat the sleep apnea.
3 . The method of claim 2 wherein programming the pulse stimulation driver includes programming the pulse stimulation driver to deliver the electrical signal over a therapy period.
4 . The method of claim 3 wherein the therapy period includes at least one active portion and at least one rest portion.
5 . The method of claim 2 , wherein the receiver device is shaped to conform to at least a portion of a patient's anatomy.
6 . The method of claim 2 , further comprising detecting, by at least one sensor, a patient airflow event.
7 . The method of claim 6 , further comprising, controlling, by a controller, power transmission to the receiver device responsive to detecting the patient airflow event.
8 . The method of claim 6 , further comprising initiating, changing, and/or halting delivery of the signal to the electrode, based at least in part on information received from the at least one sensor.
9 . The method of claim 2 , further comprising delivering, via at least one electrode of a second percutaneously implantable device positioned to be in electrical communication with the hypoglossal nerve of the patient, an electrical signal.
10 . The method of claim 2 , further comprising securing, by an anchor component carried by the percutaneously implantable device, the percutaneously implantable device proximate the hypoglossal nerve.
11 . The method of claim 2 , wherein the at least one electrode includes multiple electrodes and the method further comprises, delivering, by the multiple electrodes on the percutaneously implantable device, signals to treat the sleep apnea.
12 . The method of claim 2 , wherein the wireless transmission device provides midfield radio frequency (RF) power transmission to the percutaneously implantable device.
13 . A patient treatment system, comprising:
a wearable device carrying:
a main battery;
a power transmission device coupled to the main battery and configured to emit a radio frequency (RF) signal;
at least one sensor configured to detect a physiologic signal of a patient; and
first control circuitry coupled to the main battery, the power transmission device, and the at least one sensor, the first control circuitry including a controller programmed with instructions that, when executed determine a patient airflow event, based at least partially on input from the at least one sensor, and cause the power transmission device to transmit power based at least partially on the patient airflow event; and
a percutaneously implantable device having:
an electrode;
a housing carrying the electrode;
an anchor carried by the housing and positioned to secure the percutaneously implantable device proximate a hypoglossal nerve of the patient;
an electrode receiver device configured to receive power transmitted from the power transmission device;
a stimulation driver coupled to the electrode receiver device and the electrode to direct a signal to the electrode;
a charge storage device having a charge storage capacity less than a charge storage capacity of the main battery; and
second circuitry coupled between the stimulation driver and the electrode to control delivery of the signal to the electrode.
14 . The system of claim 13 , wherein the instructions further include initiating, changing, and/or halting the delivery of the signal to the electrode, based at least in part on information received from the at least one sensor.
15 . The system of claim 13 , wherein (i) the implantable device is a first implantable device positioned on a first side of an oral cavity and (ii) the electrode is a first electrode, the system further comprising a second implantable device positioned on a second side of the oral cavity opposite the first implantable device, the second implantable device including a second electrode.
16 . The system of claim 13 , wherein the implantable device includes a body portion extending from the housing, and wherein the electrode is positioned along the body portion.
17 . The system of claim 13 , wherein the control circuitry is configured to program the stimulation driver to deliver stimulation over a therapy period.
18 . The system of claim 17 , wherein the therapy period includes at least one active portion and at least one rest portion.
