Abstract
The disclosed technology provides systems and methods of communication between implanted medical devices, e.g., implanted pulse generators, and handheld consumer devices, e.g., smartphones, via standard wireless communication protocols, e.g., Bluetooth or Bluetooth Low Energy (BLE) operating in the unlicensed 2.4 GHz frequency band.
Claims20
An implantable medical device, comprising:
- a header section, comprising:
- a coil disposed proximate to an outer face of the header section, wherein the coil is configured to inductively couple to a wireless power transmitter;
- and
- an inverted F antenna (IFA) disposed proximate to the coil and further from the outer face of the header section than the coil, wherein the IFA comprises a grounding section, a feed section, a first radiating section, and a second radiating section, the first radiating section coupling the grounding section to the feed section.
1 more element
A method of coupling an implantable medical device to an external device, the method comprising:
- receiving an electrical signal at a feed point of an inverted F antenna (IFA), wherein the IFA is disposed in a header section of the implantable medical device;
- converting, at the IFA, the electrical signal to electromagnetic radiation;
- coupling the electromagnetic radiation to a coil disposed proximate to an outer face of the header section, wherein the coil is configured to inductively couple to a wireless power transmitter;
- and,
- radiating, by the coil, the electromagnetic radiation towards the outer face of the header section, wherein the coil enhances a radiation property of the electromagnetic radiation.
