1. An occlusion crossing device comprising:
a catheter comprising:
a driveshaft having a distal end with a drill tip; and
an outer shaft having a lumen configured to accommodate the driveshaft and to allow the driveshaft to rotate therein; and
a handle attached to a proximal end of the catheter, the handle comprising:
a lock configured to transition between a locked configuration and an unlocked configuration, wherein the lock in the locked configuration locks the driveshaft relative to the outer shaft, and wherein the lock in the unlocked configuration enables the driveshaft to be removed from the outer shaft; and
a button or ring configured to control bending of the catheter when the lock is in the locked configuration, wherein actuation of the button or ring causes a longitudinal force to be applied on the driveshaft relative to the outer shaft to bend the catheter.
