A transmitting element for generating a magnetic field for tracking of an object includes a first spiral trace that extends from a first outer origin inward to a central origin in a first direction. A second spiral trace can extend from the central origin outward to a second outer origin in the first direction. The second spiral trace can extend from the central origin to the second outer origin in the first direction. The first spiral trace and the second spiral trace can be physically connected at the central origin to form the fluorolucent magnetic transmitting element and at least a portion of the first spiral trace overlaps at least a portion of the second spiral trace.

A system and method for reducing spondylolisthesis. The system includes a bracket comprising a first opening and a second opening, a first and second rod, and a first and second knob. The system may be placed onto a patient's back, the rods may be inserted through the first opening and the second opening and further into a first vertebral part and a second vertebral part. Tightening of a first knob and a second knob on the first and second rod allow for repositioning of the vertebra. Once repositioned, an interspinous implant may be inserted into the interspinous process space, connecting the vertebrae.

The present disclosure relates to a method and a data processing system for generating navigable images of at least one region of interest ROI of a patient for a fluoroscopy-based navigation system using an X-ray imaging system, a localization system and an imaging kit, said imaging kit being configured to allow images registration in a preferred referential and tracking of surgical tools.

A salvage device for localizing a tissue marker clip includes an elongate handle having a metal ball connected to its distal end, and a probe connected to a distal end of the radiopaque fiducial element. A lumen extends through at least a portion of the elongate handle, the metal ball and the probe, terminating at a distal tip of the probe. A deployable tissue engagement member is housed at least partially within the lumen and connected to a proximal switch.

A device to be used by an operator which may grasp objects in a sterile or non-sterile field, and may facilitate the precise placement and passage of a needle or pin into tissues while using X-ray guidance. The device provides a secure hold while keeping the hands remote from the radiation field, and by permitting non-obstructed viewing of the held instrument and tissues. A radiolucent hammer may be used to help drive a needle into firm tissues without obscuring visualization.

An IM tibial nail aiming guide for providing proximal and distal screw fixation in an intramedullary nailing (IMN) of a tibia includes an attachment that connects and disconnects easily from a jig's proximal handle. Specifically, the IM tibial nail aiming guide functions as an aiming guide for accurate fixation of all the respective proximal and distal screw holes in a tibial nail. The IM tibial nail aiming guide has a length and angle that are adjustable, affording the ability to use this IM tibial nail aiming guide with any tibial nail. This IM tibial nail aiming guide is made of radiolucent material that allows for a confirmatory fluoroscopic imaging to verify that both the proximal and distal screws are fixated appropriately. The IM tibial nail aiming guide permits a more accurate, safe, versatile, and efficient approach to tibial IMN.

A system includes a first tool having a base, a nut, and a tool guide. The base extends from a first end to a second end and includes at least one thread disposed along a length thereof. The first end includes a foot having a widthwise dimension that is greater than a diameter of the at least one thread. The nut is configured to be disposed along the length of the base and to engage at least one thread. The tool guide is configured to be slideably disposed along the length of the base and has a body including a flange portion. The flange portion defines an opening for receiving at least one of a pin and a cutting tool. Rotation of the first nut causes the nut to translate along the length of the base thereby causing the tool guide to move along the length of the base.

A transmitting element for generating a magnetic field for tracking of an object includes a first spiral trace that extends from a first outer origin inward to a central origin in a first direction. A second spiral trace can extend from the central origin outward to a second outer origin in the first direction. The second spiral trace can extend from the central origin to the second outer origin in the first direction. The first spiral trace and the second spiral trace can be physically connected at the central origin to form the fluorolucent magnetic transmitting element and at least a portion of the first spiral trace overlaps at least a portion of the second spiral trace.

A substantially radiolucent cranial stabilization pin is adapted for use with a fixture for immobilizing a patient's head during a medical procedure. The pin includes a tip and a body, which are secured together to form the pin. The tip and body are constructed from non-ferrous, non-magnetic materials that are biocompatible. The tip and body are safe for use with, and compatible with, imaging techniques including MR imaging and CT imaging. In some examples the tip is a titanium insert and the body is molded within and around at least a portion of the tip. In some versions, the tip includes a hollow portion and one or more projections extending within the hollow portion. The molded body flows into the hollow portion and around the one or more projections of the tip creating a secure pin suitable to withstand torque and axial forces observed in use.

Various systems, devices, and methods for facilitating efficient anatomical registration in surgical navigation are disclosed. Such systems and devices can have a data collection unit and a scaling device. The scaling device has a main body having an anatomical registration feature defined therein and at least one scaling marker pathway that is selectively oriented with respect to the anatomical registration feature to facilitate repeatable gross placement of a scaling marker relative to a selected anatomical feature. The scaling marker is selectively displaceable along a scaling marker pathway about and between a first end and a second end thereof to fine-tune scaling marker placement prior to image capture.
