ABSTRACT:
A pacemaker terminal for connecting an electrode lead having a proximal end includes a first section fixed to the pacemaker and a second section moveably engaged with the first section. A spring element is interposed between the first and second sections to exert a force to displace the moveable section from the fixed section. Both sections have transverse holes which, upon application of squeezing pressure to the terminal to overcome the spring action, become aligned so as to allow insertion of the proximal end of the electrode lead. Thereafter, upon release of the pressure, the spring element displaces the sections so as to capture the electrode lead securely in the holes. The holes may be provided with an internal thread, such as an asymmetrial sawtooth pattern, to aid in holding the lead in place and maintaining electrical contact with it.
