A patient tracking device for insertion into a body cavity includes a flexible conformable sensor housing having a sensor cavity therein. The housing conforms to the body cavity when inserted therein. A sensor is disposed within the housing.

A head stabilization device or HFD includes a plurality of integrated markers. The HFD may be in the form of a skull clamp, vacuum bag, combinations thereof, or other supporting structure. The integrated markers include MRI markers detectable by an MRI scanner and fiducial markers detectable by a registration tool of a navigation system. The markers provide a reference point relative to an operation site in a patient for use in a navigation guided procedure and aid in registering or calibrating the location of the patient with captured images used in the navigation guided procedure.

A method for localizing a nodule of a patient includes inserting a delivery tool into tissue of a patient, such as lung tissue, releasing the magnetic fiducial into or adjacent a nodule from the delivery tool, and locating the magnetic fiducial with a localization tool.

A method for performing a surgical procedure includes planning a resection of a bone of a patient. A volume of the bone is removed according to the planned resection using a surgical tool. As the bone is removed, data corresponding to a shape and volume of the removed bone is tracked with a computer system operatively coupled to the surgical tool. A prosthesis is implanted onto the bone of the patient based on the tracked data corresponding to the shape of the removed bone.

In general, devices, systems, and methods for fiducial identification and tracking are provided.

In general, devices, systems, and methods for fiducial identification and tracking are provided.

Provided herein are systems, devices, assemblies, and methods for generating exciter signals, for example, to activate a remotely located tag. The systems, devices, assemblies, and methods find use in a variety of application including medical applications for the locating of a tag in a subject.

Systems and methods for treating a lung of a patient. One embodiment of a method comprises positioning a leadless marker in the lung of the patient relative to the target, and collecting position data of the marker. This method further comprises determining the location of the marker in an external reference frame outside of the patient based on the collected position data, and providing an objective output in the external reference frame that is responsive to movement of the marker. The objective output is provided at a frequency (i.e., periodicity) that results in a clinically acceptable tracking error. In addition, the objective output can also be provided at least substantially contemporaneously with collecting the position data used to determine the location of the marker.

Provided herein are systems and methods comprising localization agents. For example, provided herein are systems and methods for the placement of localization devices within biological systems and the detection of such localization devices for targeted surgeries or other medical procedures. For example, provided herein are systems comprising one or more miniature detectable devices that are placed into a target location and activated by remote introduction of a magnetic field.

A gastrectomy device includes an elongated member defining a centerline that extends through proximal and distal ends thereof. A shape modification member coupled to the elongated member is movable relative to the centerline of the elongated member. The shape modification member is movable between a first state, adjacent to the elongated member, and a second state, spaced from the elongated member. The shape modification member conforms to a portion of a patient's stomach in the second state.
