Abstract

An active implantable medical device (AIMD) comprising an implantable electronics module and a tissue interface. At least one of the electronics module and the tissue interface comprises an electrically non-conductive, biocompatible and needle-piercable base having one or more biocompatible electrically conductive strands of conductive filaments stitched to the base. As used herein, stitching a conductive filament to a base refers to sewing, embroidering or otherwise securing the filament to the base through the use of hand or machine needlework.

Claims (45)

1. A method of manufacturing an active implantable medical device (AIMD), comprising:

providing a biocompatible, electrically non-conductive and needle-pierce-able base;

stitching a repeating pattern with a biocompatible, electrically conductive filament to the non-conductive base;

stitching at least one active component of an electronics module to the non-conductive base; and

attaching, with the electrically conductive filament, the stitched repeating pattern of the electrically conductive filament to the at least one active component to transmit and/or receive signals,

wherein the at least one active component includes a stimulator unit configured to generate electrical stimulation, signals and the electrically conductive filament stitched in the repeating pattern delivers the electrical stimulation signals to tissue of a patient.

2. The method of claim 1 , wherein stitching the conductive filament to the base comprises:

securing the conductive filament to the base with a biocompatible, electrically nonconductive filament sewn into the non-conductive base.

3. The method of claim 2 , wherein the conductive filament is substantially positioned on a first side of the base, and wherein the non-conductive filament is disposed substantially on an opposing side of the base, and wherein the method further comprises:

stitching the conductive filament to the non-conductive base by forming a plurality of interacting lock stitches from the non-conductive filament and the conductive filament.

4. The method of claim 3 , further comprising:

forming the stitches such that the conductive filament remains entirely on the first side of the base.

5. The method of claim 1 , wherein stitching the conductive filament to the base comprises:

directly sewing the conductive filament into the base without the use of a non-conductive filament.

6. The method of claim 1 , wherein the at least one active component comprises components of an antenna.

7. The method of claim 6 , further comprising:

stitching the conductive filament into a loop pattern.

8. The method of claim 1 , wherein the at least one active component comprises a stimulator unit configured to generate electrical stimulation signals, and wherein the method further comprises:

stitching the conductive filament to the base in a pattern usable by the stimulator unit to deliver the electrical stimulation signals to tissue of a patient.

9. The method of claim 8 , further comprising:

stitching the conductive filament into a series of substantially parallel linear rows.

10. The method of claim 8 , further comprising:

stitching the conductive filament into a plurality of stitches, wherein two or more of the stitches overlap with one another.

11. The method of claim 1 , wherein providing an electrically non-conductive, biocompatible and needle-pierce-able base comprises:

providing a fabric base.

12. The method of claim 1 , wherein providing an electrically non-conductive, biocompatible and needle-pierce-able base comprises:

providing a thermo-softening plastic base.

13. The method of claim 12 , further comprising:

molding the thermo-softening plastic base into a desired shape.

14. An active implantable medical device (AIMD), comprising:

a biocompatible, electrically non-conductive and needle-pierce-able base;

at least one active component of an electronics module stitched to the non-conductive base;

a biocompatible, electrically conductive filament stitched to the base in a repeating pattern and attached to the at least one active component to transmit and/or receive signals,

wherein the at least one active component includes a stimulator unit configured to generate electrical stimulation signals, and the electrically conductive filament stitched in the repeating pattern delivers the electrical stimulation signals to tissue of a patient.

15. The AIMD of claim 14 , further comprising a biocompatible, electrically non-conductive filament sewn with the conductive filament to stitch the conductive filament to the nonconductive base.

16. The AIMD of claim 15 , wherein the conductive filament is substantially positioned on a first side of the base, and wherein the non-conductive filament is disposed substantially on an opposing side of the base, and wherein a plurality of interactive lock stitches formed from the conductive filament and the non-conductive filament secure the conductive filament to the base.

17. The AIMD of claim 16 , wherein the conductive filament remains entirely on the first side of the base.

18. The AIMD of claim 14 , wherein the at least one active component comprises components of an antenna, and wherein the conductive filament is stitched to the base in a pattern usable with the antenna components to transmit and/or receive electromagnetic signals.

19. The AIMD of claim 18 , wherein the conductive filament is stitched into the non-conductive base in a loop pattern.

20. The AIMD of claim 14 , wherein the at least one active component comprises a stimulator unit configured to generate electrical stimulation signals, and wherein the conductive filament is stitched to the base in a pattern usable by the stimulator unit to deliver the electrical stimulation signals to tissue of a patient.

21. The AIMD of claim 20 , wherein the conductive filament is stitched into the non-conductive base in a series of substantially parallel linear rows.

22. The AIMD of claim 20 , wherein the conductive filament is stitched into the non-conductive base in a plurality of rows, wherein two or more of the rows overlap with one another.

23. The AIMD of claim 14 , wherein the base comprises a fabric.

24. The AIMD of claim 14 , wherein the base comprises a thermo-softening plastic material.

25. The AIMD of claim 14 , wherein the conductive filament comprises a shape memory material.
