Abstract

An implantable medical system for implantation within the body of a patient is provided. The system includes an implanted device having an implant casing and a long range telemetry sub-system housed therein. The system also includes an implantable lead operationally coupled to the implanted device and an antenna coupled to the implant casing to extend therefrom. The antenna is operationally coupled to the long-range telemetry sub-system to enable wireless bi-directional communication between the long range telemetry sub-system and predetermined external equipment disposed outside the body of the patient.

Claims

1. An implantable medical system for implantation within the body of a patient comprising:

an implanted device including an implant casing and a long range telemetry sub-system housed therein;

an implantable lead operationally coupled to said implanted device; and

an antenna coupled to said implant casing to extend therefrom, said antenna being operationally coupled to said long range telemetry sub-system of said implanted device for wireless bi-directional communication therethrough between said long range telemetry sub-system and predetermined external equipment disposed outside the body of the patient.

2. The implantable medical system of claim 1 further comprising a connecting cable coupled between said implanted device and said implantable lead, said connecting cable including a plurality of conductors, a first of said conductors terminating at a free end to form said antenna.

3. The implantable medical system of claim 1, wherein said implanted device includes a header attached to said implant casing, said implantable lead being coupled to said implant casing through said header.

4. The implantable medical system of claim 3, wherein said antenna extends from said header and terminates at a free end disposed outside said implanted device.

5. The implantable medical system of claim 2, wherein said implantable lead includes at least one electrode, a second of said conductors of said connecting cable being coupled to said electrode.

6. The implantable medical system of claim 1, wherein said implanted device includes a window formed of a non-conductive material in a side wall of said implant casing, said antenna being disposed adjacent said window.

7. The implantable medical system of claim 6, wherein said antenna is disposed on said window to extend along an outer surface thereof.

8. The implantable medical system of claim 6, wherein said antenna is disposed on said window to extend along an inner surface thereof.

9. The implantable medical system of claim 6, wherein said antenna is disposed within said window to be at least partially embedded therein.

10. The implantable medical system of claim 1, further comprising patient alerting means operationally coupled to said implanted device.

11. The implantable medical system of claim 1, wherein said implantable lead is configured for cardiac implantation.

12. The implantable medical system of claim 1, wherein said implantable lead is configured for neurostimulation implantation.

13. The implantable medical system of claim 1, wherein the range of the data communication between said implanted device and said external equipment is greater than 1 foot.

14. The implantable medical system of claim 1, wherein the range of the data communication between said implanted device and said external equipment is greater than 1 meter.

15. The implantable medical system of claim 1, wherein said implanted device includes device circuitry housed in said implant casing, at least portion of said device circuitry being selected from the group consisting of:

electrical stimulation circuitry, pacemaker circuitry, and defibrillator circuitry.

16. The implantable medical system of claim 1, wherein said long range telemetry sub-system is switched between ON and OFF states during a preset period of time in a cyclical manner.
