Abstract

A system for interfacing an in-body medical device with an external network includes a subdermal wideband on-body network (WON) hub, which in turn includes a hub rechargeable battery, a hub processor coupled to the hub rechargeable battery, a device interface configured to communicate with the in-body medical device, and coupled to the hub processor, and a hub-satellite near field communications wireless interface coupled to the hub processor. The system also includes a wearable WON server that in turn includes a server processor, a server-satellite interface coupled to the server processor, and an external network interface coupled to the server processor. The server processor implements a software controller; and a skin-mountable WON tethered satellite that includes a wired satellite-server interface, coupled to the wearable WON server, and a tethered satellite near-field communications (NFC) wireless interface, configured to communicate with the hub-satellite NFC wireless interface, and coupled to the wired satellite-server interface.

First claim

What is claimed is:

1. A medical system for interfacing at least one in-body medical device with at least one external network, comprising:
at least one subdermal wideband on-body network (WON) hub, the at least one subdermal wideband on-body network hub comprising a hub rechargeable battery, a hub processor coupled to the hub rechargeable battery, a device interface configured to communicate with the at least one in-body medical device, and coupled to the hub processor, and a hub-satellite near field communications wireless interface coupled to the hub processor;
at least one wearable wideband on-body network (WON) server, the at least one wearable wideband on-body network (WON) server comprising a server processor, a server-satellite interface coupled to the server processor, and an external network interface coupled to the server processor;
at least one skin-mountable wideband on-body network (WON) tethered satellite, the at least one skin-mountable wideband on-body network (WON) tethered satellite comprising a wired satellite-server interface, coupled to the at least one wearable wideband on-body network (WON) server, and a tethered satellite near-field communications wireless interface, configured to communicate with the hub-satellite near field communications wireless interface, and coupled to the wired satellite-server interface; and
a software controller implemented on at least one of the subdermal wideband on-body network (WON) hub and the wearable wideband on-body network (WON) server and configured to monitor and control the at least one in-body medical device.

2. The medical system of claim 1 , wherein the at least one in-body medical device includes at least first and second devices, wherein the device interface of the at least one subdermal wideband on-body network (WON) hub is configured to communicate with the first device, further comprising at least one skin-mountable wideband on-body network (WON) wireless satellite, the at least one skin-mountable wideband on-body network (WON) wireless satellite comprising a wireless satellite-server interface coupled to the at least one wearable wideband on-body network (WON) server and a wireless satellite near-field communications wireless interface, coupled to the wireless satellite-server interface, and configured to communicate with the second device.

3. The medical system of claim 2 , wherein the at least one skin-mountable wideband on-body network (WON) wireless satellite, the at least one wearable wideband on-body network (WON) server, and the at least one skin-mountable wideband on-body network (WON) tethered satellite cooperatively form a mesh network.

4. The medical system of claim 3 , wherein the wearable wideband on-body network (WON) server further comprises a local data storage and a user interface (UI), and is configured to provide computing services for the medical system.

5. The medical system of claim 3 , wherein at least one of the skin-mountable wideband on-body network (WON) wireless satellite and the skin-mountable wideband on-body network (WON) tethered satellite comprises a smart bandage.

6. The medical system of claim 3 , wherein the skin-mountable wideband on-body network (WON) tethered satellite is configured to attach to skin above a location of the at least one subdermal wideband on-body network (WON) hub.

7. The medical system of claim 3 , wherein the hub-satellite near field communications wireless interface, the tethered satellite near-field communications wireless interface, and the wireless satellite near-field communications wireless interface are configured to provide data communication and charging at less than 20 MHz or in a range from 300 MHz to 1 GHz.

8. The medical system of claim 3 , wherein the at least one subdermal wideband on-body network (WON) hub is configured to provide common infrastructure functions to support implant operations, the implant operations comprising power, communication channels to out-of-body medical devices, signal buffering, and data compression and encryption.

9. The medical system of claim 8 , wherein the at least one subdermal wideband on-body network (WON) hub comprises a flexible substrate and is further configured to provide edge computing functionality and standard communication ports for communication with at least the first device.

10. The medical system of claim 3 , further comprising a local medical computer 404 coupled to the external network interface and configured to communicate with cloud services, monitor biomarkers, adjust parameters, and provision a therapeutic application library.

11. The medical system of claim 3 , wherein the device interface of the at least one subdermal wideband on-body network (WON) hub is configured to communicate with the first device via a wired communication path.

12. The medical system of claim 3 , wherein the device interface of the at least one subdermal wideband on-body network (WON) hub is configured to communicate with the first device wirelessly at less than 20 MHz or in a range from 300 MHz to 1 GHz.
