A system for performing a surgical procedure includes a camera configured to capture real-time near infrared images, an injection system configured to inject a fluorescent dye into a patient's blood stream, and a workstation operably coupled to the camera for retrieving a three-dimensional (3D) model of the patient's anatomy based on pre-procedure images, retrieve an indication of a targeted critical structure within the 3D model, observe, using the captured real-time near infrared images, perfusion of the fluorescent dye through tissue to identify critical structures illuminated by near-infrared light, and register the real-time near-infrared images to the 3D model using the identified illuminated targeted critical structure in the real-time near infrared images captured by the camera and the identified targeted critical structure in the 3D model as a landmark.

The present disclosure relates to systems and methods to perform a surgical procedure. The systems and methods utilize MRI-compatible fiducial markers including a body having at least one feature configured to receive an MRI-compatible and MRI-visible material and to allow registration of a navigational tool. The MRI-compatible fiducial markers can be affixed to a bone of a patient. The registered navigational tool can be used to advance a surgical tool along a navigational path to perform a surgical procedure.

An anatomical sensing system-guided prostate procedure device that includes a housing having a proximal end and a distal end. The housing may be divided into a distal housing section, a mid housing section, and a proximal housing section, wherein the distal housing section is configured for insertion into the anus and retention in the rectum of a subject. The device further includes an instrument convergence point disposed between the proximal end and the distal end, the convergence point configured to allow an instrument pass though the instrument convergence point at a variable angle; and an instrument angle orienting system at the proximal end of the housing, the angle orienting system directing an orientation of the variable angle about the convergence point. Methods of the using an anatomical sensing system-guided prostate procedure device and system including the same.

Device 1 for fixation to the skull 2 of a patient that can serve as a fiducial marker in scan guided surgical operations using a surgical instrument. The device 1 comprises a material translucent for the applied electromagnetic waves of the scan and a fiducial marker and where the device 1 comprises means to fixate the device in a well-defined manner to the surgical instrument.

Disclosed are systems and methods of lymphatic specimen tracking, visualization, and lymph node drainage pathway determination. An exemplary method includes receiving computed tomographic (CT) image data corresponding to a CT scan, generating a three-dimensional (3D) model of at least a portion of a patient's body based on the CT image data, identifying one or more lymph nodes in the 3D model, performing a registration of the 3D model with one or more physical locations in the patient's body, determining an expected lymph node drainage pathway away from a region of interest through one or more lymph nodes, and displaying the 3D model and the expected lymph node drainage pathway.

A method for detecting a magnetic marker comprises generating a driving magnetic field comprising first and second frequencies and detecting a response magnetic field comprising first and second response components. The magnetic marker provides a non-linear response to the driving signal. A primary portion of the response components is generated by the magnetic marker, and secondary portion of the response components is generated by a secondary magnetic source. The method comprises determining a driving factor representing a ratio of the frequencies in the driving signal; determining a correction factor corresponding to the secondary ortion of the second response component, based on the first response component and the driving factor; determining a detection signal corresponding to the primary portion of the second response component, based on the second response component and the determined correction factor; and generating an output signal based on a strength of the detection signal.

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.
