BIDIRECTIONAL TORQUE WRENCH
A torque wrench (model 6628) is included in the sterile tray with the pulse generator, and is designed for
tightening and loosening #2-56 setscrews, captured setscrews, and setscrews on this and other Boston
Scientific pulse generators and lead accessories that have setscrews t hat spin freely when fully retracted
(these setscrews typically have white seal plugs).
This torque wrench is bidirectional, and is preset to apply adequate torque to the setscrew and will ratchet
when the setscrew is secure. The ratchet release mechanism prevents overtightening that could result in
device damage. To facilitate the loosening of tight extended setscrews, this wrench applies more torque in the
counterclockwise d irection than in the clockwise direction.
NOTE: As an additional safeguard, the tip of the torque wrench is designed to break off if used to overtighten
beyond preset torque levels. If t his occurs, the broken tip must be extracted from the setscrew using forceps.
This torque wrench may also be used for loosening setscrews on other Boston Scientific pulse generators
and lead accessories that have setscrews that tighten against a stop when fully retracted (these setscrews
typically have clear seal plugs). However, when retracting these setscrews, stop turning the torque w rench
when the setscrew has com e in contact with the stop. The additional counterclockwise torque of this wrench
may cause these setscrews to become stuck if tightened against the stop.
Loosening Stuck Setscrews
Follow these steps to loosen stuck setscrews:
1. From a perpendicular position, tilt the torque wrench to the side 20º to 30º from the vertical center axis of
thesetscrew(Figure7onpage66).
