  • 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.

  • Publication number: 20230240513
    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.

  • Publication number: 20230201522
    Abstract: A packaging assembly for storing a steerable catheter ready for connection with a robotic system, comprises: a packaging enclosure and an alignment member configured to hold the steerable catheter in a predetermined shape. The alignment member is a carrier tube configured to align one end of the steerable catheter for connection with an actuator unit. The package and the alignment member are designed such that the steerable catheter can be connected to the actuator unit without changing the predetermined shape and while the catheter is still in the package. A robotic system is configured to connect to the steerable catheter included in the packaging assembly. The robotic system completes an initialization process to set acceptor parts of the actuator unit to a position corresponding to the predetermined shape in which the catheter is packaged.
