Abstract: A connector assembly for effectuating electrical and mechanical coupling between an implantable device and a lead comprises a main body portion and a rotating lever which collectively define a socket for receiving the terminal end of the lead therein. When the lever is in an unlocked or open position, very little insertion force is required to introduce the terminal end of the lead into the socket. When the lever is rotated to its closed position, a J-groove connection between the lever and the main body portion causes the lever to be drawn toward the main body portion. This inward travel of the lever causes an annular sealing grommet in the connector assembly to be compressed around the circumference of the lead body, effectuating a frictional and fluid-tight connection between the lead and the implantable device. In another embodiment of the invention, compression of the sealing grommet is accomplished by pressing downward on a slide element.
