A system for performing a surgical procedure includes a controller including a memory and a processor, the memory storing instructions, which when executed by the processor cause the processor to receive an image captured by a camera, generate a segmented image by applying a first threshold value to the image captured by the camera, identify a lumen within the segmented image, determine a centroid of the lumen within the segmented image, and align a portion of a surgical device operably coupled to the controller with the centroid of the lumen.

A system is suggested comprising an optical sensing means and a processing unit. The optical sensing means may include an optical guide with a distal end, wherein the optical guide may be configured to be arranged in a device to be inserted into tissue in a region of interest. The processing unit may be configured to receive information of a region of interest including different tissue types as well as of a path through the tissues, to determine a sequence of tissue types along the path, to determine a tissue type at the distal end of the optical guide based on information received from the optical sensing means, to compare the determined tissue type with the tissue types on the path, to determine possible positions of the distal end of the optical guide on the path based on the comparison of tissue types, and to generate a signal indicative for the possible positions.

A method for determining a shape of a lumen in an anatomical structure comprises reading information from a plurality of strain sensors disposed substantially along a length of a flexible medical device when the flexible medical device is positioned in the lumen. When the flexible medical device is positioned in the lumen, the flexible medical device conforms to the shape of the lumen. The method further comprises computationally determining, by a processing system, the shape of the lumen based on the information from the plurality of strain sensors.

A medical device that includes a carrier member, one or more operative components disposed in the carrier member, an optical fiber at least partly disposed in the carrier member, and at least one fiber Bragg grating (FBG) sensor array associated with the optical fiber and disposed in the carrier member. The carrier member includes an insertion end and side walls that contact the subject's body during positioning of the carrier member in the subject's body. The at least one FBG sensor array measures contact forces at one or both of the insertion end and along the side walls of the carrier member during positioning of the carrier member in the subject's body. A multi-core optical fiber configured for use in a medical device for positioning in a subject's body is also provided. A system and method for guiding positioning of a medical device in a subject's body is also provided.

Techniques for segmenting a percutaneous medical procedure based on one or more determinable phases. The techniques may include obtaining a first set of features over a first time period. The first set of features may be derived from instrument telemetry data corresponding to an endoluminal scope instrument. The technique may also include obtaining a second set of features over the first time period. The second set of features may be derived from instrument telemetry data corresponding to a percutaneous needle instrument. Based on the first set of features and the second set of features, the techniques may classify at least a portion of the first time period as a first phase of the percutaneous medical procedure.

The systems and methods of the present disclosure are used for guiding a medical instrument towards a target, the method positioning a medical instrument at a first location within a patient anatomy, wherein the medical instrument comprises at least one sensor, determining a first biomarker measurement using the at least one sensor, determining a second biomarker measurement using the at least one sensor, comparing the first biomarker measurement with the second biomarker measurement to determine a proximity to the target to provide a first comparison, and providing guidance for moving the medical instrument based on results of the first comparison.

The present disclosure relates to systems, devices, and methods to augment a two-dimensional image.

A method and system of correcting alignment of catheter relative to a target including receiving signals from an inertial measurement unit located at a distal end of a catheter, determining movement of the distal end of the catheter caused by physiological forces, receiving images depicting the distal end of the catheter and the target, identifying the distal end of the catheter and the target in the images, determining an orientation of the distal end of the catheter relative to the target and articulating the distal tip of the catheter in response to the detected movement to achieve and maintain an orientation towards the target such that a tool extended from an opening at the distal end of the catheter would intersect the target.
