ELECTRICAL CONNECTOR FOR CARDIAC DEVICES

摘要

A temporary cardiac pacing wire (10), or a similar device, includes an electrically conductive lead (18) which is folded over on itself to form a plug assembly (566) for connection to a pacing or monitoring apparatus (30). In the case of a bipolar temporary cardiac pacing wire (10), flexible wires (18, 20) are employed, one of which (18) has two elongated conductive sections (26, 28) near its proximal end, which form the plug assembly (566). The plug assembly (566) can be provided with a resilient insulating sheath (564) covering and insulating its entire length. The insulating sheath (564) automatically retracts in accordion-like fashion as the plug assembly (566) is connected to the pacing or monitoring apparatus (30, 530) and also automatically or manually extends as the plug assembly (566) is withdrawn from the pacing or monitoring apparatus (30, 530). The insulating sheath (564) can be provided with a coil spring (684) to encourage automatic extension of the sheath (564) and with an end flap (686) to further insulate the tip of an otherwise uninsulated plug assembly (566).
