International Classification:

A61N 1/08
H04W 4/00
H04B 7/14

H04B 5/02

US Classification:

607 59, 455 661, 455 411, 455 413, 455 111, 4554221

Abstract:

A communications bridge device communicates between a consumer electronics device, such as a smart telephone, and an implantable medical device. The bridge forwards instructions and data between the consumer electronics device and the implantable medical device. The bridge contains a first transceiver that operates according to a communication protocol operating in the consumer electronics device (such as Bluetooth), and second transceiver that operates according to a communications technique operating in the implantable medical device (e.g., Frequency Shift Keying). A software application is installed on the consumer electronics device, which provides a user interface for controlling and reading the implantable medical device. The software application is downloadable using standard cellular means. The bridge is preferably small, and easily and discreetly carried by the implantable medical device patient. The bridge is preferably also simple to operate, and may have only a simple user interface, or no user interface at all.

International Classification:

A61N 1/36

US Classification:

607 59, 607 61

Abstract:

An external charger system is disclosed comprising an external charger with an internal charging coil, as well as an output port coupleable to one of a plurality of types of external accessory charging coils of varying shapes and sizes. If the internal charging coil of the external charger is sufficient for a given patient's charging needs, the accessory charging coils may be detached from the external charger, and the external charger may serve as a standalone self-contained external charger. The external charger can automatically detect which of the plurality of types of accessory charging coils is connected, and can adjust its operation accordingly. This versatile design allows the external charger system to be used by large numbers of patients, even if their particular implant charging scenarios are different.

International Classification:

A61N 1/36

US Classification:

607 60, 607 61

Abstract:

An implantable medical device and external base station system are disclosed. The external base station can provide a passive electric field to power the implant, or to charge its battery. The base station may also power or charge using magnetic fields under certain circumstances. The Implantable medical device may comprise an implantable neurostimulator having a number of electrode leads extending from its body. One or more of the electrode leads can comprise the antenna for receiving the electric field from the base station, and resonance in that antenna can be rectified to provide the power for recharging the battery. Although the E-field provided by the base station does not provide as much power for recharging as does other traditional charging techniques (such as those using magnetic fields), it can occur passively and over longer distances to allow the patent's implant to be recharged when in relative proximity to the base station.

International Classification:

A61N 1/36

US Classification:

607 61

Abstract:

A base station for passively recharging a battery in an implant without patient involvement is disclosed. The base station can be hand held or may comprise equipment configured to be placed at a fixed location, such as under a bed, on or next to a wall, etc. The base station can generate electric and magnetic fields (E-field and B-field) that couple with an antenna and a receiving coil within the implant to generate a charging current for charging the implant's battery. No handling or manipulation on part of the patient is necessary; the implant battery is passively charged whenever the patient is within range of either the magnetic or electric charging fields generated by base station. Charging using the B-field occurs when the IPG is at a relatively short distance from the base station, while charging using the E-field occurs at longer distances. Back telemetry from the implant can inform the base station whether B-field or E-field charging is indicated, and is preferred if possible for its ability to transfer higher amounts of power to the implant.
