Generally, systems, methods, and apparatus related to the use of a dynamic imaging modality in an image guided intervention are disclosed herein. More specifically, the use of such modalities in sealing a bodily opening, such as those that may be formed during an invasive medical procedure are disclosed herein. In some embodiments, a method includes viewing a representation of an instrument within a body of a patient, adjusting a position of the instrument based on the viewing such that a portion of the instrument is at a location within the body of the patient, and delivering a sealant via the instrument to the location within the body of the patient. The sealant is configured to seal an opening in the body part.

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.

A surgical stapler comprising stored or storable staple cartridges is disclosed. The staple cartridges can have different unfired sizes. In at least one instance, a first stored staple cartridge comprises first staples having a first unfired height and a second stored staple cartridge comprises second staples having a second unfired height which is different than the first unfired height.

Provided herein are systems, devices, assemblies, and methods for localization of a tag in a tissue of a patient. For example, provided herein are systems, devices, and methods employing a detection component that is attached to or integrated with a surgical device, where the detection component detects a signal from a tag in a patient, where the tag is activated by remote introduction of a magnetic field.

A surgical instrument comprising a touchscreen display is disclosed.

A guidance system utilizes ultrasound imaging or other suitable imaging technology. In one embodiment, the guidance system includes an imaging device including a probe for producing an image of an internal body portion target, such as a vessel. One or more sensors may be associated with the probe. The system may include a medical device, such as a needle, separate from the probe, the medical device having a magnetic field associated therewith. The system may include a processor that uses data relating to the magnetic field sensed by the one or more sensors to determine a position and/or orientation of the medical device. The system may also include a display that shows an image of the internal body portion target taken by the ultrasound imaging probe and a depiction of the medical device positioned and/or oriented with respect to the image.

A system for tracking the position of one or more medical devices for insertion into the body of a patient is disclosed. The system may also be used to locate one or medical devices at a later time after placement thereof. The present system employs multiple radiating elements that can be simultaneously detected by a sensor unit of the system, wherein at least one of the radiating elements is included with the medical device. Another of the radiating elements may be placed at a predetermined point on the skin of the patient to serve as a landmark to help determine the location of the medical device with respect to the landmark. Detection of the radiating elements by the sensor unit enables the relative positions of the radiating elements to be ascertained and depicted on a display, to assist a clinician in accurately positioning the medical device, such as a catheter.

Described is a method for detecting and displaying the movement of a temporomandibular joint which connects a lower jaw and an upper jaw by magnetic resonance imaging. A marker is secured to the lower jaw, a marker movement curve is generated using magnetic resonance imaging measurement data sets during a first measurement interval, during which the lower jaw is moved relative to the upper jaw, and a point which corresponds to a first position of the lower jaw relative to the upper jaw is ascertained on the movement curve. An image data set is generated during a second measurement interval, during which the temporomandibular joint is not moved, and a first model, which represents at least one part of the upper jaw and/or a temporal bone part that comprises the temporomandibular joint socket, and a second model, which represents at least one part of the lower jaw, are ascertained therefrom. A movement curve of the second model relative to the first model is calculated and displayed using the marker movement curve.

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.

A wireless pressure sensing unit (20) comprises a membrane (25) forming an outer wall portion of a cavity and two permanent magnets (26,28) inside the cavity. One magnet is coupled to the membrane, and at least one magnet is free to oscillate with a rotational movement. At least one is free to oscillate with a rotational movement. The oscillation takes place at a resonance frequency, which is a function of the sensed pressure, which pressure influences the spacing between the two permanent magnets. This oscillation frequency can be sensed remotely by measuring a magnetic field altered by the oscillation. The wireless pressure sensing unit may be provided on a catheter (21) or guidewire.
