Abstract: Techniques for placing implantable electrodes to treat sleep apnea, and associated devices, systems, and methods are disclosed herein. A representative method includes percutaneously implanting one or more signal delivery devices, each at or near a respective target signal delivery location in a patient. Each signal delivery device can include one or more electrodes, and individual ones of the electrodes can be positioned to produce a net positive protrusive motor response of the patient’s tongue. The representative method further includes providing power to one or more of the electrodes from a wearable power source to cause the electrode(s) to deliver an electrical signal to the respective target signal delivery location(s) to produce the net positive protrusive motor response.

Abstract: The present technology is generally directed to delivery systems for injected neurostimulation devices, and associated systems and methods. In some embodiments, a delivery system includes a body having an at least partially hollow interior; an adjustable sheath defining a lumen, the adjustable sheath including (i) a first portion positioned within the interior of the body and (ii) a second portion extending beyond the interior; and an actuation mechanism operably coupled to the body and the adjustable sheath. The actuation mechanism can be operable to move the adjustable sheath to change a length of the second portion. 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.

Abstract: The present technology is generally directed to wearable devices for treating sleep apnea, and associated systems and methods. In some embodiments, a system for treating sleep apnea comprises an implantable device and a wearable device. The implantable device can be implantably positionable at a patient's head and/or neck, proximate to the patient's oral cavity, and include a signal generator configured to generate an electrical signal, an electrode coupled to the signal generator to direct the electrical signal to the patient's tissue, and a power receiver device coupled to the signal generator. The wearable device can include a power source and a power transmission device coupled to the power source and configured to transmit power wirelessly to the implantable device.

Abstract: A printed circuit assembly (PCA) for coupling to an IMD feedthrough of an implantable medical device includes a PCB portion and an interposer. The IMD feedthrough has a support structure and a plurality of electrical contacts extending through the support structure. The PCB portion is configured to be arranged relative to the support structure of the IMD feedthrough and includes a plurality of electrical contacts. The interposer is secured to the PCB portion and includes a dielectric over-mold structure and a plurality of leads. Each lead is integrated with the dielectric over-mold structure and includes a weld pad and a solder pad. Each solder pads of the interposer is electrically coupled to a corresponding electrical contacts of the PCB portion to provide an alignment between one or more weld pads of the interposer and one or more corresponding electrical contacts of the IMD feedthrough.

Abstract: A burr hole cover includes a cap or cap assembly and a retainer and is configured to be partially positioned within a burr hole formed in a patient. The retainer has a cap-receiving aperture; a plurality of grooves provided in the retainer and a plurality of cut-outs wherein each cut-out is provided at an end of each groove towards the outer perimeter of the retainer. A channel may be provided at an opposite end of each groove vertically-extending from the top to the bottom of the retainer to encourage a medical device segment to remain in a groove during installation of the burr hole cover. The burr hole cover may be used to secure segments of medical devices relative to a burr hole and to allow a range of lateral motion for the portion(s) of the medical device(s) extending proximally out of the corresponding groove.

Abstract: A lead fixation assembly and method of using the same are disclosed. The lead fixation assembly includes a cover and a cap. The cover includes an aperture extending through a cover body and is adapted to fit within an opening formed or occurring in a patient's body. One or more leads may be oriented through the aperture before or after fitting the cover in such an opening. The cover body includes a top surface having a plurality of elements. Each lead oriented through the aperture is arranged on or in and among the elements and may be secured thereby. The cap is adapted to be removably secured to the cover, minimize exposure to the patient via the opening, and, optionally, secure the leads. The leads are passed through an opening in the cap to enable the leads to extend away from the body.
