Abstract

In various examples, an apparatus includes an apparatus configured for implantation within a body of a patient. The apparatus, in some examples, includes a housing. At least one antenna extends from the housing, the antenna being flexible such that the antenna conforms to the body of the patient. In some examples, the apparatus includes at least three electrodes, wherein at least a first electrode is disposed on the antenna and at least a second electrode is disposed on the housing. The at least three electrodes are disposed in a non-linear configuration, allowing for differential processing of signals recorded by the at least three electrodes.

Claims

1. An apparatus configured for implantation within a body of a patient, the apparatus comprising:

a housing;

at least one antenna extending from the housing, the antenna being flexible such that the antenna conforms to the body of the patient; and

at least three electrodes, wherein at least a first electrode is disposed on the antenna and at least a second electrode is disposed on the housing, wherein the at least three electrodes are disposed in a non-linear configuration.

2. The apparatus of claim 1, wherein the at least one antenna includes at least two electrodes.

3. The apparatus of claim 2, wherein the at least two electrodes of the antenna are configured to measure a local signal and the first electrode and the second electrode are configured to measure a global signal.

4. The apparatus of claim 1, comprising a header attached to the housing, wherein the at least one antenna is coupled to the header.

5. The apparatus of claim 4, wherein at least a third electrode is disposed on the header.

6. The apparatus of claim 1, wherein the at least three electrodes provide at east three vectors along which to sense a physiologic parameter.

7. The apparatus of claim 6, wherein the physiologic parameter includes a cardiac parameter.

8. The apparatus of claim 7, wherein the cardiac parameter includes an electrocardiogram (ECU) signal.

9. The apparatus of claim 8, comprising circuitry configured to use the at least three vectors to gain or subtract a first portion of the ECG signal and amplify a remaining second portion of the ECG signal.

10. The apparatus of claim 8, comprising circuitry configured to use the at least three vectors to determine a local signal and a global signal, the circuitry being configured to subtract the local signal from the global signal to decrease an amount of noise present in the ECG signal.

11. A system comprising:

an implantable device configured for implantation within a body of a patient, the device including;

a housing;

at least one antenna extending from the housing, the antenna being flexible such that the antenna conforms to the body of the patient; and

at least three electrodes, wherein at least a first electrode is disposed on the antenna and at least a second electrode is disposed on the housing, wherein the at least three electrodes are disposed in a non-linear configuration.

12. The system of claim 11, wherein the at least three electrodes provide at least three vectors along which to sense an electrocardiogram (ECG) signal.

13. The system of claim 12, comprising circuitry configured to use the at least three vectors to gain or subtract a first portion of the ECG signal and amplify a remaining second portion of the ECG signal.

14. The system of claim 12, comprising circuitry configured to use the at least three vectors to determine a local signal and a global signal, the circuitry being configured to subtract the local signal from the global signal to decrease an amount of noise present in the ECG signal.

15. The system of claim 12, comprising an external device communicatively coupled to the implantable device, the external device configured to use the at least three vectors to gain or subtract a first portion of the ECG signal and amplify a remaining second portion of the ECG signal.

16. The system of claim 12, comprising an external device communicatively coupled to the implantable device, the external device configured to use the at least three vectors to determine a local signal and a global signal, the circuitry being configured to subtract the local signal from the global signal to decrease an amount of noise present in the ECG signal.

17. The system of claim 11, wherein the implantable device includes a header attached to the housing, wherein the at least one antenna is coupled to the header.

18. The system of claim 17, wherein at least a third electrode is disposed on the header.

19. The system of claim 11, wherein the at least one antenna includes at least two electrodes.

20. The system of claim 19, wherein the at least two electrodes of the antenna are configured to measure a local signal and the first electrode and the second electrode are configured to measure a global signal.
