  • Patent number: 11925321
    Abstract: A steerable catheter driven by a robotic controller comprises: a catheter body having a tool channel extending from a proximal to a distal end; and a positioning mechanism configured to be coupled with an imaging device and to be slidably inserted into and/or withdrawn from the catheter body through the tool channel. The positioning mechanism and/or the catheter body include an anti-twist feature configured to interlock the catheter body to the imaging device at the distal end of the catheter body so as to prevent rotation of the imaging device within the tool channel. Anti-twist features include bumps or recesses formed in the tool channel inner surface to be interlocked with one or more features formed on the positioning mechanism outer surface. Position and/or orientation of the imaging device remain substantially unchanged with respect to the tool channel when the catheter body is steered by an actuating force.

  • Patent number: 11786106
    Abstract: An endoscope imaging system comprises a robotic controlled steerable catheter and an imaging device removably arranged in a tool channel of the catheter. One or more sensors or markers are configured to map a positional relation of the catheter with respect to an orientation of the imaging device. A controller drives the steerable catheter to manipulate the distal end thereof, while the imaging device acquires an image of a subject or sample. While the imaging device acquires the image, a processor calculates a change in positional relation of the catheter with respect to the orientation of the imaging device based on information provided by the one or more sensors or markers. An output unit provides an indication for remapping the orientation of the steerable catheter with respect to the orientation of the imaging device.
