Abstract

A connector assembly and method for electrically connecting an implantable electrode having an electrical lead array to monitoring equipment. The connector assembly includes a lead holder, an electrical conductor array, and a base holding the electrical conductor array, and a resilient element. The lead holder is moveable with respect to the base from a first position to an operating position. The resilient element is adapted to bias the lead holder from the first position to the operating position.

Claims

1. A connector assembly having an interior for electrically connecting an implantable electrode having an electrical lead array to monitoring equipment, comprising:

a nonconducting lead holder,

an electrical conductor array positioned in the interior of said connector assembly,

a nonconducting base holding the electrical conductor array, wherein the lead holder is moveable with respect to the base from a first position to an operating position, and

a resilient element adapted to bias the lead holder from the first position to the operating position.

2. A connector assembly as in claim 1 wherein the resilient element is selected from a leaf spring, a coil spring, a piston, or a plunger.

3. A connector assembly as in claim 1 wherein the lead holder comprises a channel through which the lead array is inserted.

4. A connector assembly as in claim 1 wherein the resilient element is adapted to bias the lead holder in the direction of the conductor array.

5. A connector assembly as in claim 1 wherein the resilient element is adapted to bias the conductor array in the direction of the lead holder.

18. The connector assembly of claim 1 wherein said connector assembly further comprises a base, a base cap, a cover and a lead holder cap and wherein said cover is transparent to allow viewing the interior of said connector assembly.

19. The connector assembly of claim 1 wherein the conductor array is comprised of at least one conductor having a longitudinal body and an end and wherein each said conductor body is split longitudinally at its end.

20. The connector assembly of claim 1 wherein said channel of said nonconducting lead holder is further comprised of a wall for holding said electrical lead array of an implantable electrode.

6. A connector assembly having an interior for electrically connecting an implantable electrode having an electrical lead array to monitoring equipment, comprising:

a nonconducting lead holder having a channel through which the lead array is inserted,

an electrical conductor array in the interior of said connector assembly,

a nonconducting base holding the electrical conductor array, having an opening adapted to be aligned with the channel in the holder and having thereon a resilient element which causes the electrical connector array to be biased against the lead array, wherein the holder moves relative to the base such that when the opening in the base is aligned with the channel in the holder, the lead array is inserted into the channel causing electrical contact between the lead array and the electrical conductor array.

7. A connector assembly as in claim 6 wherein the resilient element is selected from a leaf spring, a coil spring, a piston, or a plunger.

8. A connector assembly having an interior for electrically connecting an implantable electrode having an electrical lead array to monitoring equipment, comprising:

a nonconducting lead holder,

an electrical conductor array positioned in the interior of said connector assembly,

a nonconducting base holding the electrical conductor array,

wherein the lead holder is moveable with respect to the base from a first position to an operating position, and

a means of biasing the lead holder from the first position to the operating position.

9. A connector assembly as in claim 8 wherein the means of biasing is selected from a leaf spring, a coil spring, a piston, or a plunger.

10. A connector assembly as in claim 8 wherein the means of biasing the lead holder is adapted to bias the lead holder in the direction of the conductor array.

11. A connector assembly as in claim 8 wherein the means of biasing the lead holder is adapted to bias the conductor array in the direction of the lead holder.

17. The connector assembly of claim 8 wherein said assembly includes a transparent cover.

12. A method for electrically connecting a lead array from an electrode to an external monitoring device, comprising:

providing a connector assembly having an interior and comprising;

a nonconducting lead holder,

an electrical conductor array positioned in the interior of the connector assembly,

a nonconducting base holding the electrical conductor array, wherein the lead holder is moveable with respect to the base from a first position to an operating position, and

a resilient element adapted to bias the lead holder from the first position to the operating position;

inserting the lead array into the lead holder, and

urging the lead array and the base toward each other by means of the resilient element, thus making electrical contact between the lead array and the electrical conductor array.

13. The method of claim 12 wherein in the step of providing the connector assembly, the resilient element is selected from a leaf spring, a coil spring, a piston, or a plunger.

14. The method of claim 12 wherein in the step of providing the connector assembly, the lead holder comprises a channel through which the lead array is inserted.

15. The method of claim 12 wherein in the step of providing the connector assembly, the resilient element is adapted to bias the lead holder in the direction of the conductor array.

16. The method of claim 12 wherein in the step of providing the connector assembly, the resilient element is adapted to bias the conductor array in the direction of the lead holder.
