ABSTRACT:
A tooless pulse generator to lead connection for an implantable cardiac stimulator includes first and second transversely extending slots formed in the header and intersecting the lead cavities formed therein. Fitted into the rectangular slots are first and second rectangular plates, each having an elongated hole therethrough. Leaf-type springs incorporated into the rectangular slots normally urge the two plates in opposite directions causing the apertures therein to be non-aligned. By squeezing on rubber buttons affixed to the ends of the respective plates and bonded to the header, the apertures formed through the plates can be brought into alignment, allowing the lead body and the proximal pin to be easily inserted through the aligned openings and into the connector block. When the squeezing force is released, the springs again urge the apertures in the plates out of alignment and, in doing so, they deform the plastic sheath of the lead body and tightly grip same to prevent the leads from being pulled free of the lead cavities formed in the header even when a tension force of about three lbs. is applied to the leads.
