  • Publication number: 20240382168
    Abstract: Some devices, systems, and methods obtain a fluoroscopic image and corresponding C-arm positional information of the fluoroscopic image, wherein the fluoroscopic image depicts a distal end of a bendable medical device, and wherein the C-arm positional information indicates a rotation angle of a C-arm of a C-arm scanner; obtain an orientation of the distal end in an image plane of the fluoroscopic image, wherein the image plane is defined in a detector reference frame; obtain an instructed direction; determine, in the image plane, a movement direction of the distal end that corresponds to the instructed direction; map the movement direction from the image plane to a distal-end reference frame of the distal end, wherein the mapping is based on an orientation of the distal end in an intermediate reference frame and on the C-arm positional information; and control the distal end to move according to the mapped movement direction.

  • Patent number: 12082883
    Abstract: Exemplary methods and systems that provide a curved path trajectory that can be used with a bendable medical device. The curved pathway can comprise straight and curved concatenated arc segments. The methods and systems can provide planning, visualizing and treatment of, for example, temporal lobe epilepsy (TLE) using laser interstitial thermal therapy (LITT) or tumors using ablation therapy. With curved pathway, the physician can create plan for intervention to avoid critical structure and to cover more target volume for treatment/diagnosis than straight pathway.

  • 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.
