Electrical connector and cover for simultaneously connecting wires, bedside monitor, and temporary pacemaker

An interface unit for epicardial pacemaking and telemetry monitoring comprising:

• an electrically insulating housing;
• first and second electrical terminals accessible through corresponding apertures in the housing and adapted to releasably receive first and second epicardial lead wires extending into an interior of the housing parallel to an insertion axis;
• a first electrical connector attached to the insulating housing to releasably receive a pacemaker connector at third and fourth electrical terminals;
• a second electrical connector attached to the insulating housing to receive a telemetry monitor connection at a fifth terminal;
• a circuit positioned within the housing, the circuit providing electrical communication between the second and third electrical terminals and between the first, fourth terminal and the fifth terminal;
• an electrically insulating shroud providing first and second apertures for receiving the first and second epicardial wires therethrough before the first and second epicardial wires are received by the first and second electrical terminals and movably attached to the housing to move between a first position proximate to the first and second terminals and a second position removed from the first and second terminals providing an insulating cover over the first and second epicardial wires extending outward from the first and second terminals;
• and
• buttons capturing the first and second epicardial lead wires wherein the buttons are on a left and right opposed surfaces of the housing wherein the buttons are biased by a spring along an actuation axis to capture the first and second epicardial lead wires wherein the buttons are opposed first and second buttons biased in opposite direction along the actuation axis by a shared spring.
