Abstract
The system (2) includes a catheter drive unit (22) and a catheter (24) extending therefrom movably mounted to a catheter drive sled (26). The catheter drive unit rotates and translates the catheter core (34) within the catheter sheath (36). The sled has a serrated, conical drive unit interface (82), with a bag-piercing tip (86) mateable with a translator drive output (92) so that a sterile drape (112) enclosing the catheter drive unit is automatically pierced when the catheter drive unit is mounted to the sled. A control unit (6) is spaced apart from the catheter drive unit and provides power and commands to the catheter drive unit and receives information and data from the catheter drive unit. The rotator and translator drive motors (54, 90) are operated from both the control unit and the catheter drive unit. Both the control unit and catheter drive unit have translation displacement displays (10, 30).
