Abstract
An implantable medical device has an implantable power supply and an implantable medical unit. The implantable supply powers the device and it includes a hermetically sealed supply housing, a battery, and a supply power coupler that powers the implantable medical unit from the battery via a wireless coupling. The implantable medical device also has a hermetically sealed medical unit housing, and it includes a functional medical module including a continuous glucose meter module. In use, the implantable medical unit is releasably mechanically coupled to the implantable supply and a wireless coupling of a medical unit power coupler with a supply power coupler is made, thereby powering the medical unit from the battery of the implantable supply.
Claims20
An implantable medical device, comprising:
- an implantable supply and an implantable sensor, the implantable supply further comprising:
- a hermetically sealed supply housing;
- a battery;
- a wireless supply power coupler configured for powering the implantable sensor from the battery via wireless coupling;
- a wireless supply data coupler configured for wireless data communication with the sensor;
- a wireless supply communication interface configured for wireless communication with a non-implanted remote control;
- and
- a supply coupling arrangement configured for releasably mechanically coupling the sensor to the implantable supply;
- wherein the battery, the supply power coupler, the supply data coupler and the supply communication interface are enclosed by the supply housing;
- the implantable sensor comprising:
- a hermetically sealed sensor housing;
- a continuous glucose meter;
- a wireless sensor power coupler configured to receive power from the supply power coupler by wireless coupling, thereby powering the sensor;
- a wireless sensor data coupler configured for wireless data communication with the supply;
- and
- a sensor coupling arrangement that mates with the supply coupling arrangement;
- wherein the supply coupling arrangement includes a receiving recess in the supply housing configured for receiving at least part of the sensor, the sensor coupling arrangement including a proximal end received within the supply coupling arrangement in radial spaced relation to the supply coupling arrangement to define a non-galvanic coupling;
- wherein the battery is rechargeable and the implantable supply includes a wireless charging coupler configured for wireless charging of the battery from the non-implanted remote control in an implanted state of the implantable supply;
- wherein the receiving recess of the supply coupling arrangement in the supply housing is configured for receiving the proximal end of the sensor coupling arrangement;
- wherein at least part of the sensor housing is inserted into the supply housing, and at least part of the continuous glucose meter extends outside of the supply housing distal of the sensor coupling arrangement.
