Abstract: Technologies disclosed herein can be used to provide power and data to an implantable device implanted in a recipient, such as when the recipient is not wearing an external device. An example system includes a pillow or other headrest configured as a power and data source for an implanted medical device. Disclosed technologies can be configured to continuously provide power and data to an implantable medical devices over a period of time, such as substantially the entire period of time where the recipient is resting their head on the pillow.

Abstract: Method and system embodiments for controlling power provided to a device implantable in a subject are described. In some embodiments, a method is performed at the implantable device to receive, from an interrogator, powering ultrasonic waves having a wave power. Then, energy from the powering ultrasonic waves is converted into an electrical signal to power the implantable device. Information that indicates whether more power or less power should be transmitted to the implantable device is transmitted to the interrogator.

Abstract: A prosthetic cardiac valve includes a frame and plurality of prosthetic leaflets coupled to the frame so as to allow blood flow in one direction. An antenna is mechanically coupled to the frame, and includes a magnetic core and one or more coils wound about the magnetic core. At at least one location along a length of the magnetic core, a planar space bound by an outer perimeter of the magnetic core, in a plane perpendicular to a central longitudinal axis of the frame, has (a) a shorter dimension, which is measured along a ray that radiates radially outward from the central longitudinal axis and intersects a centroid defined by the planar space, and (b) a longer dimension, which is measured perpendicular to the shorter dimension in the plane, and is at least 150% of the shorter dimension. Other embodiments are also described.

Abstract: A polymeric film cover assembly for isolating an electrochemical power source from the other components housed inside an implantable medical device is described. The cover assembly comprises a first shallow-formed shaped-cover of a polymeric film configured to cover a first portion of the exterior surface of the casing and a second shallow-formed shaped-cover of the polymeric film configured to cover a second portion of the exterior surface of the casing. With the first and second shaped-covers contacting the casing, the shaped-covers are connected to each other in an overlapping or butted relationship to substantially or completely cover the exterior surface area of the casing. The interlocking polyester shaped-covers are readily formable into the desired three-dimensional form factor of the casing of power source while maintaining a desirable film thinness.

Abstract: A wireless implant and associated system for motor function recovery after spinal cord injury, and more particularly a multi-channel wireless implant with small package size. The wireless implant can further be used in various medical applications, such as retinal prostheses, gastrointestinal implant, vagus nerve stimulation, and cortical neuromodulation. The system also includes a method and its implementation to acquire the impedance model of the electrode-tissue interface of the implant.

Abstract: The present technology is generally directed to medical implants, such as stimulation assemblies for stimulating heart tissue. In some embodiments, a stimulation assembly includes a body, circuitry positioned at least partially within the body, an electrode coupled to the body, and a hook mechanism coupled to the body. The stimulation assembly can be implanted at cardiac tissue of a patient such that the electrode electrically contacts the tissue. The circuitry can be configured to receive acoustic energy and convert the acoustic energy to electrical energy, and the electrode can deliver the electrical energy to the tissue to stimulate the tissue. The hook mechanism can be configured to engage the tissue to pull the tissue and the electrode toward and into engagement with one another.

Abstract: Described herein are devices, systems, and methods for wireless power transfer utilizing a midfield source and implant. In one variation, a midfield source may be realized by a patterned metal plate composed of one of more subwavelength structures. These midfield sources may manipulate evanescent fields outside a material (e.g., tissue) to excite and control propagating fields inside the material (e.g., tissue) and thereby generate spatially confined and adaptive energy transport in the material (e.g., tissue). The energy may be received by an implanted device, which may be configured for one or more functions such as stimulation, sensing, or drug delivery.

Abstract: Systems and methods are disclosed that allow a patient to self-treat a medical condition, such as migraine headache and trigeminal neuralgia and the like. The system comprises a stimulator configured for wireless coupling to a mobile device and comprising a signal generator that generates an electrical impulse and an energy source. The stimulator includes a contact surface configured to contact an outer skin surface of a head of a patient and a user interface for selecting a therapy regimen. The stimulator transmits the electrical impulse transcutaneously through the outer skin surface to a nerve at a target region of the head, wherein the electrical impulse is sufficient to modulate the nerve and modify the medical condition. The system further comprises a software program downloadable onto the mobile device and configured to communicate with the stimulator.
