Abstract

An active implantable medical device (AIMD). The AIMD comprises: a knitted electrode assembly comprising: at least one biocompatible, electrically non-conductive filament arranged in substantially parallel rows each stitched to an adjacent row, and at least one biocompatible, electrically conductive filament having a first end intertwined with a first row of the at least one non-conductive filament, and a second end intertwined with a second row of the at least one non-conductive filament, wherein the first and second rows are spaced from one another.

Claims (20)

1. A method for manufacturing a knitted implantable electrode assembly comprising:

providing at least one biocompatible implantable, electrically non-conductive filament, and at least one biocompatible implantable, electrically conductive filament;

winding first and second ends of a first of the at least one conductive filament around spaced sections of the at least one non-conductive filament; and

knitting the at least one non-conductive filament having the conductive filament wound there around into an intermeshed looped structure having substantially adjacent parallel rows, each row stitched to an adjacent row with one or more loops, and the first end of the first of the at least one conductive filament intertwined with a first row of the at least one non-conductive filament to form a connector contact, and a second end of the first of the at least one conductive filament intertwined with a second row of the at least one non-conductive filament to form an electrode, wherein the first and second rows are spaced from one another and the connector contact and the electrode are spaced from one another by one or more third rows of the at least one non-conductive filament between the connecting contact and electrode.

2. The method of claim 1 , wherein the at least one non-conductive filament consists of a single non-conductive filament, and wherein the method comprises:

knitting the single non-conductive filament into substantially parallel rows each stitched to an adjacent row with the at least one conductive filament intertwined with the non-conductive filament.

3. The method of claim 1 , further comprising:

concurrently knitting the first and second ends of at least one conductive filament with first and second sections, respectively, of the at least one non-conductive filament such that the first and second ends each follow the same course as sections of at least one non-conductive filament, and wherein the first and second ends are positioned on the exterior surface of the electrode assembly.

4. The method of claim 1 , wherein knitting the at least one non-conductive filament into the plurality of parallel rows comprises:

circular knitting the at least one non-conductive filament into an elongate tube.

5. The method of claim 1 , wherein knitting the at least one non-conductive filament into the substantially parallel rows comprises:

flat knitting an electrode assembly having substantially planar dimensions.

6. The method of claim 1 , further comprising:

knitting one or more regions of the electrode assembly with one or more of the at least one conductive filament and the at least one non-conductive filament under varying tension.

7. The method of claim 1 , further comprising:

knitting at least one region of the electrode assembly about an elongate structure with one or more of the at least one conductive filament and the at least one non-conductive filament under tension such that the at least one region takes the shape of the surface of the elongate structure following the release of the tension from the one or more of the at least one conductive filament and the at least one non-conductive filament.

8. The method of claim 1 , wherein providing the one or more non-conductive filaments comprises:

providing at least one non-conductive filament comprising a thermo-softening plastic material.

9. The method of claim 8 , further comprising:

molding a region of the electrode assembly into a desired shape.
