Abstract
A steerable catheter driven by a robotic controller comprises: a catheter body having a catheter tip and tool channel which spans from a proximal end of the catheter body and through the catheter tip along a catheter axis. The catheter tip includes a ramp-like surface formed inside part of the tool channel diameter. The ramp-like surface is an inclined flat surface formed at an angle with respect to a plane parallel to the catheter axis, such that the angle increases as the ramp-like surface spans from distal end towards the proximal end of the catheter tip. A housing mechanism permanently attached to an imaging device is configured to lock the imaging device to the ramp-like surface so as to prevent rotation of the imaging device with respect to the tool channel and/or prevent twisting of the catheter tip with respect to the imaging device.
