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 charging coil disposed proximate to one outer face of the header section;
- an inverted F antenna (IFA) disposed proximate to the charging coil and further from the outer face of the header section than the charging 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, the second radiating section being disposed in a plane parallel to the charging coil and perpendicular to the first radiating section, and the second radiating section being longer than the first radiating section;
- an epoxy fill encapsulating the charging coil and IFA;
- and
- a base section disposed in a plane perpendicular to and below the charging coil;
- a body section coupled to the header section and housing circuitry;
- and
- an insulation section disposed between the base section of the header section and the body section, comprising insulated openings allowing the feed section and the grounding section of the IFA to penetrate the base section of the header section and to electrically couple to the circuitry in the body section.
6 more elements
A method of coupling an implantable medical device to a hand-held 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 charging coil disposed proximate to one outer face of the header section;
- and,
- radiating, by the charging coil, the electromagnetic radiation towards the one outer face of the header section, wherein the charging coil enhances a radiation property of the electromagnetic radiation.
