Abstract: The present technology is generally directed to implantable medical device systems for stimulating tissue, such as heart tissue. In some embodiments, an implantable medical device system includes a controller-transmitter and a receiver-stimulator in operable communication with one another. The receiver-stimulator can be implanted at the heart of a patient. The controller-transmitter can be configured to transmit an acoustic signal to the receiver-stimulator, which receives the acoustic signal and converts the acoustic signal to electrical energy for delivery to the heart via one or more stimulation electrodes. The receiver-stimulator can further be configured to transmit a radiofrequency signal to the controller-transmitter including information about sensed physiological parameters of the patient, status information, and the like.

Abstract: Systems, devices, and methods discussed herein can be for validating a position of a wirelessly powered electrostimulation device while the device is implanted in body tissue. A method can include situating the electrostimulation device in tissue and before an affixation mechanism of the electrostimulation device is deployed to maintain an implanted position of the electrostimulation device, and while electrodes of the device are in contact with the tissue, performing electrical testing of the electrostimulation device to determine whether the electrostimulation from the electrostimulation device evokes a specified response from the body that contains the tissue.

Abstract: The present technology is generally directed to methods for addressing a patient's sleep apnea. At least some of the methods can include one or more of percutaneously inserting an implantable signal delivery device at an insertion point on the patient's neck, moving the signal delivery device in a medial-to-lateral direction toward an ansa cervicalis nerve of the patient, and implanting the signal delivery device at a target location at least proximate to the ansa cervicalis nerve. The signal delivery device can include at least one electrode positioned to deliver a modulation signal to tissue at least proximate to the target location, such as a portion of the ansa cervicalis nerve. In some embodiments, delivery of the modulation signal can induce caudal traction in the patient and thereby address the patient's sleep apnea.

In some embodiments, a stimulation assembly includes a body, circuitry positioned at least partially within the body, an electrode, and an anchor coupled to the body. The anchor can be secured to the septal wall such that the body is positioned within the left ventricle of the heart and the electrode engages tissue of the septal wall. The circuitry can be configured to receive acoustic energy and to convert the acoustic energy to electrical energy, and the electrode can deliver the electrical energy to the tissue of the septal wall to stimulate the tissue.

A representative system includes non-implantable signal generator worn by the patient and having an antenna that directs a mid-field RF power signal to an implanted electrode. The implanted electrode in turn directs a lower frequency signal to a neural target, for example, the patient's hypoglossal nerve. Representative signal generators can have the form of a mouthpiece, a collar or other wearable, and/or a skin-mounted patch.

A user can operate the delivery system to position an implantable device at or near a target location within a patient. In some instances, the user may use image-based navigation and/or stimulation-based navigation to identify the position of the delivery system and/or the implantable device relative to target location.
