Abstract
A percutaneous access device implantable beneath the skin of a patient includes a turret assembly containing current limiters, electrical contacts and fluid couplings and includes a sealing device having a small screw fastener at the bottom of the turret assembly. A screwdriver is provided configured to have access through a required air inlet passage to provide rapid removal and replacement of a new turret. The screwdriver includes a shaft having an eccentric drive socket. A handle has a roller clutch bearing pressed in place to allow the handle to freely turn clockwise to tighten the screw but locks the handle to the shaft for screw extraction in the counterclockwise direction. A driver captively engages a fastener for assembling a first part having a shoulder to a mating fitting having an aperture. The driver includes a shaft having a fastener-engaging end, and a mechanism, operably engageable between the shaft and the first part, for holding the fastener in a full forward position against the shoulder of the first part during attachment of the fastener to the aperture of the mating fitting.
