The present disclosure relates to implantable neuromodulation devices, and in particular to a wireless power coil in a low profile environment such as with a neurostimulator. Particularly, aspects of the present disclosure are directed to a medical device that comprises a lossy housing surrounding a power supply, and a receiving coil configured to exchange power wirelessly via a wireless power transfer signal and deliver the power to the power supply. The receiving coil is adjacent the lossy housing. The receiving coil is a helical structure with a total rise that is less than or equal to a height of the lossy housing.

Wireless power receiver coil for neuromodulation device

A biocompatible electrical connection includes a substrate; a ferrule having a concentric flange at a first end of the ferrule; a first adhesive; and a second adhesive. The first adhesive adheres a first surface of the concentric flange of the ferrule to a surface of the substrate. The second adhesive fills an annular space between a hole in the substrate and the ferrule. The first adhesive or the second adhesive forms a conductive path on the surface of the substrate between the ferrule and a circuit pattern on the substrate.

Biocompatible electromechanical connection for ceramic substrate electronics for biomedical implant

The present disclosure relates to implantable neuromodulation devices, and in particular to a wireless power coil for a neuromodulation device that is to be implanted in a minimally invasive manner, for example, through a trocar or cannula. Particularly, aspects of the present disclosure are directed to a medical device that includes a lossy housing surrounding a power supply, and a receiving coil configured to exchange power wirelessly via a wireless power transfer signal and deliver the power to the power supply. The receiving coil is spaced a predetermined distance from the lossy housing. The medical device further includes a gap provided between the lossy housing and the receiving coil on a vertical plane, and a spacer that fills in at least a portion of the gap to maintain the lossy housing a predetermined distance from the receiving coil.

Wireless power receiver coil for implantable neuromodulation device

A wireless power system for an implantable device is described. The system includes multiple inductive charging coils to increase an effective area for receiving an electromagnetic charging field from a wireless charging device. The multiple inductive charging coils produce different alternating current signals in response to receiving the electromagnetic charging field. The system includes a rectifying circuit for rectifying the alternating current signals into direct current signals. The system also includes a current combination circuit for combining the multiple direct current signals into a single direct current for powering an operation of the implantable device. Methods and devices for implementing the power system in an implantable device are also described.

Multi-coil wireless power system

A biocompatible electrical connection includes: a substrate; a ferrule having a concentric flange at a first end of the ferrule; a first adhesive; and a second adhesive. The substrate includes a hole having a diameter that is a specified amount larger than an outside diameter of the ferrule forming an annular space between the hole and the ferrule, the first adhesive adheres a first surface of the concentric flange of the ferrule to a first surface of the substrate, and the second adhesive fills the annular space between the hole and the ferrule.
