Abstract

An electrical conductive path for medical electronic device generally includes a plurality of stackable molded non-conductive housing with each housing having a bore therethrough alignable with adjacent housing bores. The adjacent housings and define any combination when stacked, spaced apart slots for receiving a plurality of electrically conductive spring rings. A plurality of electrically conducting garter springs are disposed within corresponding spring rings and a cable is provided including wires attached to corresponding spring rings.

Claims

1. An electrical conductive path for a medical electronic device, the conductive path comprising:

a plurality of stackable molded non-conductive housings, each housing having a bore therethrough alignable with adjacent housing bores, said adjacent housings defining, in combination, spaced apart slots;

a plurality of electrically conductive spring rings, each ring disposed in a corresponding slot;

a plurality of electrically conducting garter springs, each spring disposed within a corresponding spring ring;

snap fittings removably holding the adjacent housings to each other; and

a cable having a plurality of wires, each wire attached to a corresponding spring ring.

2. The path according to claim 1 wherein each housing includes an alignable hole and the path further comprises pins for aligning the housing holes.

3. The path according to claim 1 wherein the adjacent housing further define, in combination, seal grooves and the path further comprises a plurality of washer seals, each washer seal being disposed in a corresponding seal groove.

4. The path according to claim 3 further comprising snap fittings removably holding adjacent housings to each other.

5. The path according to claim 1 wherein the housing includes windows exposing the spring rings.

6. The path according to claim 5 wherein the wires are attached to the corresponding spring rings within the windows.

7. The path according to claim 1, wherein said snap fittings comprise overlapping circumferential portions of each adjacent housings.

8. An electrical conductive path for a medical electronic device, the conductive path comprising:

a header;

a plurality of stackable molded non-conductive housings disposed in said header, each housing having a bore therethrough alignable with adjacent housing bores, said adjacent housings defining, in combination, spaced apart slots;

a plurality of electrical conductive spring rings, each ring disposed in a corresponding slot;

a plurality of electrically conducting garter springs, each spring disposed within a corresponding spring ring;

a cable having a plurality of wires, each wire attached to a corresponding spring ring;

a lead including a rod receivable by the housing bores, said rod having a plurality of spaced apart electrical terminals corresponding to the spaced apart spring slots;

snap fittings removably holding the adjacent housings to each other; and

a latch removably holding the rod in position within the bores with electrical connection between corresponding rod terminals and springs.

9. The path according to claim 8 wherein each housing includes an alignable hole and the path further comprises pins for aligning the housing holes.

10. The path according to claim 8, wherein the adjacent housing further define, in combination, seal grooves and the path further comprises a plurality of washer seals, each washer seal being disposed in a corresponding seal groove.

11. The path according to claim 10 further comprising snap fittings removably holding adjacent housings to each other.

12. The path according to claim 8 wherein the housing includes windows exposing the spring rings.

13. The path according to claim 12 wherein the wires are attached to the corresponding spring rings within the windows.

14. The path according to claim 8 wherein said snap fittings comprise overlapping circumferential portions of each adjacent housings.
