User interface for external charger for implantable medical device
User interface for external power source, recharger, for an implantable medical device. At least some of patient controls and display icons of an energy transfer unit are common with at least some of the patient controls and the display icons of a patient control unit. An energy transfer unit is operable by the patient with less than three operative controls to control energy transfer from the external energy transfer unit to the implantable medical device. An external antenna having a primary coil can inductively transfer energy to a secondary coil of the implantable medical device when the external antenna is externally placed in proximity of the secondary coil. An energy transfer unit has an external telemetry coil allowing the energy transfer unit to communicate with the implantable medical device through the internal telemetry coil in order to at least partially control the therapeutic output of the implantable medical device.
1. An implantable medical device system, comprising:
an implantable medical device for providing a therapeutic output to a patient;
an external patient control unit adapted to be operatively coupled with said implantable medical device allowing said patient to control said therapeutic output of said implantable medical device; and
an external energy transfer unit adapted to be operatively coupled to said implantable medical device to transcutaneously transfer energy to said implantable medical device;
said external patient control unit having a user interface operable by said patient, said user interface of said patient control unit having a first plurality of icons indicative of a status of operation of said patient control unit, each individual one of said first plurality of icons corresponding to an individual one of a plurality of patient control unit functions or statuses;
said energy transfer unit having a user interface operable by said patient, said user interface of said energy transfer unit having a second plurality of icons indicative of a status of operation of said energy transfer unit, each individual one of said second plurality of icons corresponding to an individual one of a plurality of energy transfer unit functions or statuses;
at least some of said second plurality of icons of said energy transfer unit being common with at least some of said patient controls and said first plurality of icons of said patient control unit.
2. A system as in claim 1 wherein at least one of said first plurality of icons and said second plurality of icons comprises an icon representative of a state of charging of an energy storage device in said implantable medical device.
3. A system as in claim 1 wherein at least one of said patient control unit functions or statuses and at least one of said energy transfer unit functions or statuses comprises a control for adjusting said therapeutic output of said implantable medical device.
4. A system as in claim 1 wherein said external energy transfer unit inductively couples energy to said implantable medical device.
5. A system as in claim 1 wherein said implantable medical device has a rechargeable energy storage device and wherein said energy transfer unit charges said rechargeable energy storage device.
6. A method of providing therapeutic output to a patient using an implantable medical device, comprising the steps of:
operatively coupling via telemetry an external patient control unit with said implantable medical device allowing said patient to control said therapeutic output of said implantable medical device; and
operatively coupling an external energy transfer unit to said implantable medical device to transcutaneously transfer energy to said implantable medical device;
said external patient control unit having a user interface operable by said patient, said user interface of said patient control unit having a first plurality of icons indicative of a status of operation of said patient control unit, individual ones of said first plurality of icons corresponding to individual ones of a plurality of patient control unit functions or statuses;
said energy transfer unit having a user interface operable by said patient, said user interface of said energy transfer unit having a second plurality of icons indicative of a status of operation of said energy transfer unit, individual ones of said second plurality of icons corresponding to individual ones of a plurality of energy transfer unit functions or statuses;
at least some of said second plurality of icons of said energy transfer unit being common with at least some of said first plurality of icons of said patient control unit.
7. A method as in claim 6 wherein at least one of said first plurality of icons and said second plurality of icons comprises an icon representative of a state of charging of an energy storage device in said implantable medical device.
8. A method as in claim 6 wherein at least one of said patient control unit functions or statuses and at least one of said energy transfer unit functions or statuses comprises a control for adjusting said therapeutic output of said implantable medical device.
9. A method as in claim 6 wherein said external energy transfer unit inductively couples energy to said implantable medical device.
10. A method as in claim 6 wherein said implantable medical device has a rechargeable energy storage device and wherein said energy transfer unit charges said rechargeable energy storage device.
