Abstract
A connector system for use with a sealed implantable medical device having at least one lead receiving channel for slidably receiving a connecting end of an electrical lead comprises a support member fixed to the medical device having a threaded bore generally parallel to and spaced from the lead receiving channel, an annular seal member mounted on the support member at the open end of the lead receiving channel and coaxial and aligned therewith, and a plunger adapted for attachment to the medical device and having an inlet bore for reception of the electrical lead and an annular flange coaxial with the inlet bore. When positioned for attachment to the medical device, the annular flange is coaxial with the lead receiving channel and aligned and engageable with its associated annular seal member. A driver bevel gear is mounted on the plunger for rotation about a driver axis extending transverse of the inlet bore and a driven bevel gear is mounted on the plunger for rotation about a driven axis extending perpendicular to the driver axis and meshingly engaged with the driver bevel gear. The driven bevel gear includes an integral threaded stud coaxial therewith threadedly engaged with …
