Embodiments of the present disclosure provide a surgical robot system may include an end-effector element configured for controlled movement and positioning and tracking of surgical instruments and objects relative to an image of a patient's anatomical structure. In some embodiments the end-effector and instruments may be tracked by surgical robot system and displayed to a user. In some embodiments, tracking of a target anatomical structure and objects, both in a navigation space and an image space, may be provided by a dynamic reference base located at a position away from the target anatomical structure.

A detection system and method uses an implantable magnetic marker comprising at least one piece of a large Barkhausen jump material (LBJ). The marker is deployed to mark a tissue site in the body for subsequent surgery, and the magnetic detection system includes a handheld probe to excite the marker below the switching field for bistable switching of the marker causing a harmonic response to be generated in a sub-bistable mode that allows the marker to be detected and localised. The marker implanted may also be shorter than the critical length required to initiate bistable switching of the LBJ material.

The disclosure provides for a systems and methods for monitoring uterine contractions of a uterus of a mammal by reconstructing three-dimensional images of uterine surface electrical activity based on a noninvasively obtained body-uterus geometry and a plurality of body surface electrical potential maps.

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.

A medical procedure system, including a medical instrument to be inserted into a body part, and including position-tracking transducers to provide position signals, a distal end, and at least one radiopaque marker, a position tracking sub-system to compute a position including at least one location and orientation of the distal end in a position-tracking sub-system coordinate frame responsively to the position signals, a fluoroscope to capture fluoroscopic images of an interior of the body part and the radiopaque marker(s), and a registration sub-system to render, to a display, the captured fluoroscopic images including at least one marker-image of the radiopaque marker(s), and at least one graphical representation indicative of the computed position of the distal end, receive user-alignment input aligning the graphical representation(s) with the marker-image(s), and register the position-tracking sub-system coordinate frame with a coordinate frame of the fluoroscope responsively to the received user-alignment input.

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

Example methods and systems may be used intraoperatively to help surgeons perform accurate and replicable surgeries, such as knee arthroplasty surgeries. An example system combines real time measurement and tracking components with functionality to compile data collected by the hardware to register a bone of a patient, calculate an axis (e.g., mechanical axis) of the leg of the patient, assist a surgeon in placing cut guides, and verify a placement of an inserted prosthesis.

In an endoscope apparatus including a processor, the processor specifies the position of a specific region and sets a reference scale in a picked-up image that is obtained from the image pickup of a subject on which the specific region formed by auxiliary measurement light is formed. Then, the processor extracts a region of interest, determines a measurement portion, calculates a measured value obtained from the measurement of the measurement portion, on the basis of the reference scale, and generates a measured value marker using the measured value. Further, the processor creates a specific image in which the measured value marker is superimposed on the picked-up image.

A sacral lead system including a sacral lead configured to for insertion within a sacral foramen of a patient. The sacral lead supports one or more electrodes which may be configured as one or more stimulation electrodes and/or one or more sensing electrodes. The sacral lead is configured to deliver a stimulation signal to a patient using at least one stimulation electrode and sense an evoked signal produced in response to the stimulation signal using at least one sensing electrode. The sacral lead system may be configured to position the at least one stimulation electrode and/or the at least one sensing electrode within, dorsal, or ventral to the sacral foramen. The sacral lead system may include stimulation circuitry configured to generate the stimulation signal and sensing circuitry configured to receive a signal indicative of the evoked signal.

An implantable array, such as an electrode array, is provided. The array is suitable for being placed in anatomic tissue of a human or animal body, and has a structure for referencing predefined distinct points of the implantable electrode array in magnetic resonance images. A structure is arranged in a predefined portion of the implantable array, where the structure has multiple patterns, each pattern having a predefined form and formed from a material having a magnetic susceptibility which is different from the magnetic susceptibility of the anatomic tissue surrounding the implantable array when placed in the human or animal body. Each pattern is in a predefined spatial relationship with one of the predefined distinct points.
