The present disclosure is directed to systems and methods for intraoperative medical imaging A computing system may access, from a database, a first tomogram derived from scanning a volume within a subject prior to an invasive procedure. The first tomogram may identify a target within the volume of the subject. The computing system may acquire data via an endoscopic device within the subject at a time instance during the invasive procedure. The computing system may provide, for display, in the first tomogram of the subject, a first relative location of a distal end of the endoscopic device and the target based on the data. The computing system may receive a second tomogram of the volume at the time instance. The computing system may register the second tomogram with the first tomogram to determine a second relative location of the distal end and the target.

A method for displaying guidance information using a graphical user interface during an medical procedure comprises displaying, in a first mode of the graphical user interface, first image data from a perspective corresponding to a distal end of an elongate device. The first image data includes a virtual roadmap. The method also comprises transitioning from the first mode of the graphical user interface to a second mode of the graphical user interface. The transition is based on an occurrence of a triggering condition. The method also comprises displaying, in the second mode of the graphical user interface, second image data from a perspective corresponding to the distal end of the elongate device. The second image data includes a target indicator corresponding to a target location and an alignment indicator corresponding to an expected location of the medical procedure at the target location.

A method for cleaning the lens of a visualization device integrated into a ventilation tube positioned inside a patient, wherein the tube comprises a ventilation lumen and the lens is positioned proximal to the distal end of the ventilation lumen, the method comprising providing a suction catheter comprising a brush at its distal end; positioning the catheter inside the ventilation lumen such that the brush protrudes from the distal end of the ventilation lumen; and manipulating the catheter at its proximal end to cause the brush to make contact with the lens in order to clean the lens.

A parameter value regarding an endoscope operation at an arbitrary position on a course is calculated from a three-dimensional image indicating a luminal structure. Specifically, one of a clockwise direction and a counterclockwise direction around an axis is set to positive, the other is set to negative, and a rotation angle of the endoscope due to a rotation operation at a position of a target is calculated so that a sum of a cumulative total of rotation angles of the endoscope due to a rotation operation performed until the distal end portion of the endoscope arrives at the position of the target after the distal end portion of the endoscope is inserted into a luminal structure, and the rotation angle of the endoscope due to the rotation operation at the position of the target falls within a predetermined angle range.

Certain aspects relate to biopsy apparatuses, systems and techniques for biopsy using a biopsy pattern. Some aspects relate to moving a distal portion of a medical instrument to one or more sample locations of the biopsy pattern and guiding the instrument to obtain tissue samples from the sample locations within the biopsy pattern. Some aspects relate to obtaining the biopsy pattern and adjusting the sample locations within the biopsy pattern based on various factors such as anatomical features.

A medical tracking system includes a percutaneous needle, a localization element and a navigation system is disclosed. The percutaneous needle has an elongate shaft extending between a proximal end portion, which is attached to a handle, and distal end portion that terminates at a distal tip. An inner surface of the elongate shaft defines a working channel that extends from a port at the proximal end portion to the distal tip. The localization element is incorporated into the elongate shaft distal from the handle and proximate the distal end portion. The navigation system is configured for tracking the localization element and to provide a real-time display of a position and orientation of the distal tip relative to an anatomy of a patient.

A method for treating tissue through a branched luminal network of a patient is provided. A pathway to a point of interest in branched luminal network of a patient is generated. An extended working channel is advanced transorally into the branched luminal network and along the pathway to the point of interest. The extended working channel may be positioned in a substantially fixed orientation at the point interest. A tool is advanced though the extended working channel to the point of interest. Tissue at the point of interest is treated.

An energy delivery system for performing tissue ablation at the distal end of an Electromagnetic Navigation Bronchoscopy (ENB) instrument. The system is insertable through an instrument channel of a steerable instrument cord in an ENB instrument, and comprise a coaxial cable with a radiating tip portion. The tip portion comprises a first conductive element electrically connected to the coaxial cable's inner conductor and a second conductive element electrically isolated from the inner conductor. The conductive elements are arranged to act as: an active electrode and a return electrode for delivering the RF energy into tissue surrounding the radiating tip portion, and an antenna for radiating the microwave energy as a localized microwave field. The system may be arranged to delivery energy according to a predetermined profile comprising interleaving periods of RF and microwave energy or a combination thereof, or a dynamic profile based on detected tissue impedance.

Methods and systems for navigating to a target through a patient's bronchial tree are disclosed including a bronchoscope, a probe insertable into a working channel of the bronchoscope and including a location sensor, and a workstation in operative communication with the probe and the bronchoscope, the workstation including a user interface that guides a user through a navigation plan and is configured to present a central navigation view including a plurality of views configured for assisting the user in navigating the bronchoscope through central airways of the patient's bronchial tree toward the target, a peripheral navigation view including a plurality of views configured for assisting the user in navigating the probe through peripheral airways of the patient's bronchial tree to the target, and a target alignment view including a plurality of views configured for assisting the user in aligning a distal tip of the probe with the target.

A method, system and program product are provided for planning an intervention procedure in a body lumen. A CT scan of the body lumen is performed. A virtual rendering is created of the inside of the body lumen corresponding to an interventional camera image. Then a virtual tape corresponding to a planned path for the intervention procedure is projected onto a wall of the body lumen. The virtual tape is projected onto the lumen wall, which is relatively distant from the camera point on the virtual rendering, so the tape does not appear to oscillate like a central thread. Also, since the virtual tape is located on the lumen wall, it does not occlude the center of the lumen, allowing a user to better visualize the lumen during planning, during fly through, and even during an actual intervention.
