Method and system for reversibly controlled drilling of luminal occlusions

摘要

A luminal drilling system includes a drilling device and a control unit. The drilling device includes an elongate member having a drive shaft with a drill tip. The control unit includes a motor connectable to the drive shaft and control circuitry which rotationally oscillates the drive shaft with the direction of rotation automatically reversing whenever the load on the motor and/or drive shaft exceeds a threshold value.
