Abstract

An implantable medical and related cardiac rhythm management system include a device having a housing, means disposed within the housing for performing a function, and a header operatively associated with the housing, containing a first coil communicating with the means for facilitating a function, wherein the first coil is adapted and configured to facilitate bi-directional inductive telemetry with a second coil associated with an external programming device. Alternatively, in accordance with another aspect of the invention, the external programming device includes a second coil adapted and configured to form an inductive link with the first coil to facilitate uni-directional inductive telemetry between the external programming device and the pacemaker, with return communications being transmitted separately from the pacemaker to the external programming device.

Claims

1. An implantable medical device comprising:

a) a housing;

b) means disposed within the housing for performing a function; and

c) a header operatively associated with the housing and containing a first coil communicating with the means for facilitating a function, wherein the first coil is adapted and configured to facilitate inductive telemetry with a second coil associated with an external programming device.

2. The implantable medical device as recited in claim 1, wherein the first coil is adapted and configured to facilitate bi-directional inductive telemetry with a second coil associated with an external programming device.

3. The implantable medical device as recited in claim 1, wherein the first coil is adapted and configured to facilitate uni-directional inductive telemetry with a second coil associated with an external programming device, to provide forward communication to the implantable medical device.

4. The implantable medical device as recited in claim 3, wherein return communications from the implantable medical device are transmitted though a secondary transmitter.

5. An implantable medical device as recited in claim 1, further comprising means disposed within the housing for harvesting energy from the first coil.

6. An implantable medical device as recited in claim 5, further comprising a power regulator disposed within the housing for regulating power harvested from the first coil.

7. An implantable medical device as recited in claim 1, wherein the means for performing a function includes means for further comprising a power regulator disposed within the housing for facilitating cardiac rhythm management.

8. An implantable medical device as recited in claim 1, wherein the first coil is coiled in the plane of the implantable medical device.

9. An implantable medical device as recited in claim 1, wherein the first coil is arranged in the header to inductively interface with a magnetic field oriented perpendicularly to the plane of the medical device.

10. An implantable medical device as recited in claim 1, wherein the first coil is arranged in the header to inductively interface with a magnetic field oriented substantially perpendicularly to the surface of a patient'"'"'s body, when implanted therein.

11. A cardiac rhythm management system comprising:

a) an implantable pacemaker having a housing with a header cavity, wherein means are disposed within the housing for facilitating cardiac rhythm management and a first coil is disposed within the header cavity, wherein the first coil communicates with the means for facilitating cardiac rhythm management; and

b) an external programming device having a wand operatively associated therewith, wherein the wand includes a second coil adapted and configured to form an inductive link with the first coil to facilitate bidirectional inductive telemetry between the external programming device and the pacemaker.

12. A cardiac rhythm management system as recited in claim 11, further comprising means disposed within the pacemaker housing for harvesting energy from the first coil.

13. A cardiac rhythm management system as recited in claim 12, further comprising a power regulator disposed within the housing for regulating power harvested from the first coil.

14. A cardiac rhythm management system as recited in claim 11, wherein the first coil is arranged in the header and the second coil is arranged in the wand to facilitate an inductive link therebetween.

15. A cardiac rhythm management system as recited in claim 14, wherein the first coil and the second coil are arranged so as to generate parallel magnetic fields when in use.
