  • Publication number: 20210322765
    Abstract: An implantable electrical stimulation medical system is disclosed. The system includes an implantable medical device having electrical circuitry configured to perform electrical stimulation, a nonstandard implantable medical lead, and an adapter matrix. The adapter matrix electrically interfaces with the electrical circuitry and the nonstandard implantable medical lead to provide electrical stimulation from the implantable medical device to the nonstandard implantable medical lead.

  • Publication number: 20210121708
    Abstract: Systems and methods for improved user experience with rechargers for implantable medical devices. An external charging device for providing power to a rechargeable implantable device can determine a firmware state of the external charging device during recharging of the rechargeable implantable device, display a searching indication using a light indicator when the firmware state is determined to be in a searching state, display a charging indication using the light indicator when the firmware state is determined to be a charging state, and display an error indication using the light indicator when the firmware state is determined to be an error state. An optional user device application can provide complementary graphical user interfaces according to the firmware states.

  • Publication number: 20210121707
    Abstract: A method for controlling charging a power source of an implantable medical device (IMD) in a patient including determining a power being delivered to a primary coil of an external charging device for recharging, determining an estimated power delivered to the IMD power source an estimated heat generated by the primary coil based on a resistance of the primary coil determined as function of at least one of a recharge frequency, a temperature of the primary coil, and a current supplied to the primary coil, calculating an estimated heat generated by the IMD by subtracting the estimated heat generated by the primary coil and the estimated power delivered stored by the rechargeable power source from the power being delivered to a primary coil; and controlling based on the heat generated by the IMD, the power being delivered by the primary coil of the external charging device.

  • Publication number: 20210085987
    Abstract: The instant application relates to inductive charging of devices subject to migration. Embodiments described herein provide charging to devices at variable depths and locations to accommodate both net displacement of an implantable device as well as angular rotation of the implantable device by selecting appropriate sets or subsets of available field generation coils.

  • Patent number: 9666750
    Abstract: Photovoltaic cells having copper contacts can be made by using copper nanoparticles during their fabrication. Such photovoltaic cells can include a copper-based current collector located on a semiconductor substrate having an n-doped region and a p-doped region. The semiconductor substrate is configured for receipt of electromagnetic radiation and generation of an electrical current therefrom. The copper-based current collector includes an electrically conductive diffusion barrier disposed on the semiconductor substrate and a copper contact disposed on the electrically conductive diffusion barrier. The copper contact is formed from copper nanoparticles that have been at least partially fused together. The electrically conductive diffusion barrier limits the passage of copper therethrough.

  • Patent number: 9005483
    Abstract: Nanoparticle paste formulations can be configured to maintain a fluid state, promote dispensation, and mitigate crack formation during nanoparticle fusion. Such nanoparticle paste formulations can contain an organic matrix and a plurality of metal nanoparticles dispersed in the organic matrix, where the plurality of metal nanoparticles constitute about 30% to about 90% of the nanoparticle paste formulation by weight. The nanoparticle paste formulations can maintain a fluid state and be dispensable through a micron-size aperture. The organic matrix can contain one or more organic solvents, such as the combination of one or more hydrocarbons, one or more alcohols, one or more amines, and one or more organic acids. Optionally, the nanoparticle paste formulations can contain about 0.01 to about 15 percent by weight micron-scale metal particles or other additives.
