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.

Systems, methods, and devices are provided for assisting or performing guided interventional procedures using custom templates. The system uses pre-procedure scans of a patient's anatomy to identify targets and critical structures. A template is then manufactured containing guide elements. During a procedure, the template may be aligned to the patient and instruments passed though the guide elements and into various targets. The template may be aligned using one or more of, for example, a position sensing system or a live imaging modality to register the patient to the template. The system makes optional use of devices designed to immobilize or track an organ during therapy.

Embodiments of the invention provide a system and method for resecting a tissue mass. The system for resecting a tissue mass includes a surgical instrument and a first sensor for measuring a signal corresponding to the position and orientation of the tissue mass. The first sensor is dimensioned to fit insider or next to the tissue mass. The system also includes a second sensor attached to the surgical instrument configured to measure the position and orientation of the surgical instrument. The second sensor is configured to receive the signal from the first sensor. A controller is in communication with the first sensor and/or the second sensor, and the controller executes a stored program to calculate a distance between the first sensor and the second sensor. Accordingly, visual, auditory, haptic or other feedback is provided to the clinician to guide the surgical instrument to the surgical margin.

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.

For the field of determining the position of an invasive device (1) a solution for improving the localization of the invasive device (1) is specified. This is achieved by an arrangement and a method for determining the position of an invasive device (1), wherein an optical shape sensing system for sensing a position and/or shape of the invasive device (1) is provided, wherein the system is arranged to localize at least one point P.sub.i on the invasive device (1) at a position x.sub.i, y.sub.i, z.sub.i, with some en-or margin (2Δx.sub.i, 2Δy.sub.i, 2Δz.sub.i) in a region of interest (3), localizing and reconstructing at least one point P.sub.i on the invasive device (1) at a position x.sub.i, y.sub.i, z.sub.i, with some error margin (2Δx.sub.i, 2Δy.sub.i, 2Δz.sub.i) in a region of interest (3) by the optical shape sensing system. An MRI system is also provided for measuring the position x.sub.i, y.sub.i, z.sub.i of the point P.sub.i on the invasive device (1) within the error margin in the region of interest at least in one spatial direction by the MRI system, wherein a signal of the magnetization in the error margin (2Δx.sub.i, 2Δy.sub.i, 2Δz.sub.i) is read out by the MRI system and a position of the invasive device (1) is determined based on the signal. The position x.sub.i, y.sub.i, z.sub.i, of the point P.sub.i on the invasive device (1) in the region of interest (3) determined by the optical shape sensing system is corrected with the x.sub.i, y.sub.i, z.sub.i, of the point P.sub.i on the invasive device (1) in the region of interest (3) determined by the MRI system by a calculating system to an actual position of the point P.sub.i on the invasive device (1).

A surgical instrument for treating the stomach tissue of a patient is disclosed. The surgical instrument comprises a handle comprising a display, a shaft extending from the handle, and an end effector extending from said shaft. The surgical system comprises a tissue treatment system configured to treat the stomach tissue along a path, an imaging system configured to capture a tissue image of the stomach tissue, and a controller configured to determine an edge of the stomach tissue, generate an image representing at least a portion of the edge of the stomach tissue, and display the image along with at least a portion of the tissue image on the display.

A localization tool for localizing and marking a nodule of a patient includes a magnetic portion for locating a magnetic fiducial marker disposed in or adjacent the nodule, and an electrocautery element for marking the nodule or tissue adjacent the nodule upon locating the magnetic fiducial marker.

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.

Embodiments of the invention provide devices, systems, and methods that precisely identify a minimum of one predetermined spot which is hidden under a skin. The system comprises a locator device and corresponding implanted target device. The port locator device preferably comprises one magnet with north and south magnetic pole, a body and a suspending component. The body may utilize specific geometry which improves accuracy. The implanted target device may include at least one magnet and at least one target or a plurality of targets and at least one magnet. Various configurations can be provided that precisely identify a single spot or a plurality of spots which are hidden under a skin.

A method includes, receiving from a calibration probe multiple data points acquired in an organ of a patient, each data point including (i) a respective position of the calibration probe, and (ii) a respective set of electrical values indicative of respective impedances between the position and multiple electrodes attached externally to the patient. A mapping between sets of the electrical values and respective positions in the organ is constructed, by performing for each received data point: if the mapping already contains one or more existing data points in a predefined vicinity of the data point, the one or more existing data points are adjusted responsively to the received data point, and if the predefined vicinity does not contain any existing data points, the received data point is added to the mapping. A position of a medical probe is subsequently tracked in the organ using the mapping.
