Abstract
A medical lead adaptor that provides a rapid, secure, insulated connection of the lead connector end assembly of a cardiac lead having electrodes adapted to be placed in or on the body with an external medical device. The adaptor connector assembly is configured with an elongated receptacle to accept a bipolar, in-line, or a unipolar lead connector end sharing common dimensions. The elongated receptacle includes connector pin and ring receptacle contacts spaced apart from one another. In a preferred embodiment, an elongated slot extends laterally with respect to the elongated receptacle and cooperates with a lock mechanism to permit lateral insertion of the lead connector end assembly. A stylet wire is then inserted into a cardiac lead body lumen, in the elongated receptacle. When inserted therein, the lead connector ring or pin is nested into contact with the ring or pin receptacle contacts and is held there by the lock mechanism.
