Abstract
A setscrewless connector assembly mounted on an implantable tissue stimulation device has an actuator mechanism for fixing, sealing and electrically isolating one or more electrical leads inserted into one or more corresponding lead receptacles within the connector assembly. Fixing and sealing of a lead are accomplished by compressing a resilient lead lock seal of O-ring shape, disposed in an annular recess, with a lip portion of a plunger drawn toward a molded support by the actuator mechanism. In a preferred embodiment, constant-force, high resolution compression of the lead lock seal by the plunger is provided by an actuator comprising a longitudinally extending shaft having a threaded end threadedly coupled to the plunger and an opposite end disposed within the molded support. A driver element, accessible from a side of the connector assembly, is coupled to the opposite end of the threaded shaft. The actuator preferably includes a transmission in which the driver element is journaled in a side wall of the molded support and includes a driver bevel gear in mesh with a driven bevel gear mounted on the opposite end of the threaded shaft. The mechanism is actuated by rotating the d…
