Abstract

The present disclosure relates to a high capacity medical device connector utilizing flexible circuits. The use of flexible circuits allows for increased channel capacity for use with future designs and capabilities of medical devices. The assembly may include pre-mounted electrical components. The connector may be designed to connect two flexible circuits. The connector may also be designed to connect a flexible circuit with existing technology, such as a pin-to-socket connector.

First claim

What is claimed is:

1. An electrical connection apparatus for a medical device, the electrical connection apparatus comprising:
a flexible circuit comprising:
a base area;
at least one tab area extending from the base area, the tab area being configured to be folded substantially perpendicular to the base area;
a plurality of contact nodes disposed on the base area;
a plurality of contact pads disposed on the at least one tab area at an end away from the base area; and
a plurality of electrical pathways individually connecting each of the contact nodes to one of the contact pads;

an internal holder comprised of a face area and at least one side perpendicular to the face area, wherein the base area of the flexible circuit is disposed on the face area of the internal holder and the at least one tab area is disposed on the at least one side when folded;
a plurality of lead wires individually attached to the plurality of contact pads on the at least one tab area of the flexible circuit; and
an encasement surrounding the flexible circuit and internal holder and having an opening at one end, wherein the encasement is configured to be attached to a second electrical connection apparatus and wherein the opening is configured to allow electrical connections between the plurality of contact nodes disposed on the base area of the flexible circuit and the second electrical connection apparatus.

2. The electrical connection apparatus of claim 1 , further comprising:
at least one aperture located on the face area of the internal holder; and
at least one aperture located in the base area of the flexible circuit aligned with and having substantially the same size and cross-section as the aperture on the face area of the internal holder;
wherein the at least one aperture on the internal holder and the at least one aperture on the flexible circuit are configured to accept a portion of the second electrical connection apparatus.

3. The electrical connection apparatus of claim 1 , further comprising a pressure means configured to maintain physical contact between the contact nodes on the base of the flexible circuit and the second electrical connector apparatus.

4. The electrical connection apparatus of claim 3 , wherein the pressure means comprises a spring.

5. The electrical connection apparatus of claim 4 , wherein the spring is a material disposed between the face area of the internal holder and the base area of the flexible circuit.

6. The electrical connection apparatus of claim 1 , further comprising a conductor layer disposed on top of the base area of the flexible circuit, the conductor layer having a plurality of conducting nodes extending through opposite sides of the conductor layer, the conducting nodes on a first side of the conductor layer being in contact with the contact nodes on the flexible circuit.

7. The electrical connection apparatus of claim 6 , wherein the conductor layer is comprised of a compressible material and is configured to maintain contact between the conducting nodes and the contact nodes on the flexible circuit when compressed.

8. The electrical connection apparatus of claim 1 , further comprising:
at least one shaft attached to the internal holder and extending substantially perpendicular from the face area of the internal holder; and
at least one aperture located in the base area of the flexible circuit, the aperture configured to accept the shaft,
wherein the shaft is configured to facilitate connection of the electrical connection apparatus to the second electrical connection apparatus.

9. The electrical connection apparatus of claim 8 , wherein the shaft is hollow and is configured to receive a portion of second electrical connection apparatus.

10. The electrical connection apparatus of claim 1 , wherein the flexible circuit comprises one or more electronic components mounted on its surface.

11. The electrical connection apparatus of claim 10 , wherein the one or more electronic components are comprised of at least one of a logic component, a memory component, and a switch.

12. A electrical connection adapter, the adapter comprising:
a cover having an opening at one end, the opening being configured to connect to a second electrical connection;
a flexible circuit attached to the cover at an end opposite the opening, the flexible circuit comprising:
a base area adjacent to the cover;
at least one tab area extending from the base area, the tab area configured to be folded substantially perpendicular to the base area and away from the cover;
a plurality of contact nodes disposed on the base area, the contact nodes extending through the flexible circuit;
a plurality of contact pads disposed on the at least one tab area at an end away from the base area; and
a plurality of electrical pathways individually connecting each of the contact nodes to one of the contact pads; and

a plurality of electrical connectors disposed within the cover, the electrical connectors being individually electrically and mechanically attached to the plurality of contact nodes on the base area of the flexible circuit.

13. The electrical connection adapter of claim 12 , wherein the plurality of electrical connectors are pins configured to connect to a socket-type connector.

14. The electrical connection adapter of claim 12 , wherein the plurality of electrical connectors are sockets configured to connect to a pin-type connector.

15. The electrical connection adapter of claim 12 further comprising an encasement surrounding the cover and the flexible circuit and configured to provide mechanical connection with a second electrical connection.

16. The electrical connection adapter of claim 12 further comprising a plurality of lead wires individually attached to the plurality of contact pads on the at least one tab area of the flexible circuit.

17. An electrical connection adapter, the adapter comprising:
a hollow connector body having an open end and a closed end opposite the open end;
a flexible circuit having a base area, the base area being attached to the connector body on the outside of the closed end, the flexible circuit further comprising:
at least one tab area extending from the base area, the tab area configured to be folded substantially perpendicular to the base area and away from the connector body;
a plurality of contact nodes disposed on the base area, the contact nodes extending through the flexible circuit;
a plurality of contact pads disposed on the at least one tab area at an end away from the base area; and
a plurality of electrical pathways individually connecting each of the contact nodes to one of the contact pads; and

a plurality of electrical connectors disposed within the connector body and extending through the closed end of the connector body, the electrical connectors being individually electrically and mechanically attached to the plurality of contact nodes on the base area of the flexible circuit and terminating near the open end of the connector body.
