Abstract

The invention of the disclosure is an extension cable to connect via telemetry, an external medical device in a non-sterile zone with a medical device that is within a sterile zone. The telemetry extension cable includes a cable having a length and comprising a conductor, a first RF antenna attached at one end of the cable and a second RF antenna attached at a second end of the cable, at least one of the first or second antennas configured to transmit and receive RF signals to and from an implantable medical device.

Claims

1. A telemetry extension cable comprising:

a cable having a length and comprising a conductor;

a first RF antenna attached at one end of the cable; and

a second RF antenna attached at a second end of the cable, at least one of the first or second antennas configured to transmit and receive RF signals to and from an implantable medical device.

2. The telemetry extension cable of claim 1 wherein each of the first and second RF antennae comprises a coil of a conductor.

3. The telemetry extension cable of claim 1 wherein each of the first and second RF antennae comprises an array of coiled conductors.

4. The telemetry extension cable of claim 1 wherein one of the first or the second telemetry head further comprises a magnet.

5. The telemetry extension cable of claim 1 wherein each of the first and second RF antennae are substantially planar.

6. The telemetry extension cable of claim 1 wherein each of the first and second RF antennae are in the form of a substantially planar disc.

7. The telemetry extension cable of claim 1 wherein the cable and each of the first and second antennae further comprise a coating of a polymer material capable of being sterilized.

8. The telemetry extension cable of claim 1 further comprising a pair of cable connectors along the cable, each cable connector defining an end of a portion of cable, the pair of cable connectors adapted to releasably connect the cable portions.

9. A system for connecting an external medical device to an implantable medical device comprising:

an external medical device having a telemetry head connected to the external medical device; and

a telemetry extension cable having first and second RF antennae at each end of the telemetry extension cable, the first RF antenna configured to be placed under the telemetry head, the second RF antenna configured to transmit and receive RF signals to and from an implantable medical device.

10. A kit comprising:

a cable having a first portion with a first length and a second portion with a second length, the first portion of the cable having an RF antenna at an end and a cable connector at another end, the second portion of the cable having an RF antenna on an end and a cable connector at another end, the cable connectors configured to releasably connect the first and second cable portions together, at least one of the first or second cable portions is sterile.

11. The kit of claim 10 wherein the first or second sterile cable portion is packaged within sterile packaging.

12. The kit of claim 10 wherein at least the first or second sterile cable portion is disposable.
