Abstract: 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.

Abstract: Systems, devices, and methods are discussed herein for wirelessly transmitting power and/or data to an implanted device, such as an implanted electrostimulator device. In an example, the subject matter includes a layered transmitter device with multiple conductive planes and excitation features. The transmitter device can be tuned to identify and apply device parameters for efficient wireless communication with a deeply implanted device. The transmitter is generally configured for midfield powering applications by providing signals that give rise to propagating signals inside of body tissue.

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.

Systems, devices and methods for interacting with (e.g., communicating with, receiving power from) an external device are also provided. A system can include an external power source that propagates a field within tissue and an at least partially implantable device configured to receive the propagated field from the external power source, the implantable device including circuitry, a first antenna electrically coupled to the circuitry, a second antenna electrically coupled to the first antenna, and an electrode electrically connected to the circuitry.

Abstract: Systems, devices and methods to facilitate wireless interaction between an implantable therapy delivery device and an external transmitter device are provided. In an example, the systems, devices, and methods discussed herein include or use a garment for receiving and positioning an external transmitter device proximal to an implanted device, and the external transmitter device includes a midfield device configured to provide one or more signals to manipulate evanescent fields outside of tissue to generate a propagating and focused field in the tissue. In an example, the garment includes a receptacle configured to receive and retain the external transmitter device near a tissue interface, and the garment further includes a dielectric portion provided between the receptacle and the tissue interface. In an example, the dielectric portion has a relative permittivity that is approximately the same as the relative permittivity of air.
