Abstract

An electrode system for use in conjunction with body implantable electro-medical devices is disclosed. The system includes a socket having first coupling means. The socket forms an electrical output terminal of the electro-medical device. A plug forms a part of the system and is disposed on the proximal end of an electrical conductor which also forms a part of the system. The plug comprises an electrical connector secured to the conductor and having second coupling means, and a compressible resilient means. The resilient means provides a locking biasing force between the first and second coupling means when the plug and socket are coupled.

Claims

1. An electrical connector assembly for providing an electrical connection between an electromedical device and an electrical conductor, the electrical conductor having proximal and distal ends with the distal end of the conductor being adapted for contact with a body organ of a patient, the electrical connector assembly comprising:

a. socket means constructed and arranged to form an electrical output terminal of the electromedical device, the socket means having a cylindrical cavity and pair of spaced, oppositely disposed pin means extending into the cavity; and

b. plug means, the plug means comprising i. an electrical connector secured to the proximal end of the conductor, the electrical connector being cylindrical and having coupling means cooperable with each of the pin means of the socket means to effect a electrical and positive locking coupling between the socket means and the plug means, the coupling means of the electrical connector comprising a pair of oppositely disposed axial and a pair of oppositely disposed radial grooves all located in the cylindrical outer surface of the connector, the radial grooves extending circumferentially in the same direction and each having a regressed portion into which a pin means of the socket means is disposed when the plug means and the socket means are coupled; and

ii. compressible resilient means partially extending over the electrical connector and having portions thereof engageable with cooperating portions of the electromedical device for providing a locking biasing force between the socket means and the electrical connector when the plug means and the socket means are coupled.

2. An electrical connector assembly as defined in claim 1 wherein the electrical connector has an axial passage therethrough and includes a tubular member disposed within the axial passage, the proxiMal end of the conductor being located within the tubular member and secured thereto.

3. In apparatus so defined in claim 1 wherein the compressible resilient means comprises a body compatible material.

4. In apparatus as defined in claim 3 wherein the compressible resilient means comprises silicon rubber.
