In an indwelling device including a device body and an engaging part connected to the device body and capable of abutting on a bodily wall, the engaging part can abut on the bodily wall in a state that a region of the engaging part, excluding end parts, is expanded radially outward from an outer peripheral surface of the device body.

A uterine manipulator includes a housing and a shaft extending distally from the housing. An end effector assembly is disposed at a distal end portion of the shaft. The end effector assembly includes a cervical cup and a uterine manipulating tip portion extending distally from the cervical cup. A position sensor is supported by the cervical cup. The position sensor is configured to identify a location of the cervical cup.

The inventions provided herein relate to tissue markers and uses thereof, e.g., to mark a target tissue site (e.g., a biopsy site in a breast tissue) or to produce a cell scaffold. The tissue markers described herein are designed to be resistant to fast migration (e.g., immediate migration after implantation through a needle track) and slow migration (e.g., over an extended period of time) upon implantation at a target tissue site (e.g., a biopsy site in a breast tissue), without using an adhesive. Additionally or alternatively, the tissue markers described herein can be readily detectable by at least one imaging modality, e.g., but not limited to magnetic resonance imaging, X-ray imaging, ultrasound imaging, or a combination thereof.

In a method and system for reducing motion artifacts in magnetic resonance image data acquired from a facial region of a patient, the patient is positioned in an imaging region of a magnetic resonance imaging device configured to perform a magnetic resonance measurement of the facial region of the patient, the magnetic resonance measurement is performed to acquire magnetic resonance image data of the facial region of the patient, and a motion correction technique is employed exploiting an accessibility to the facial region of the patient during the magnetic resonance measurement. The motion correction technique advantageously reduces an influence of a patient motion on the magnetic resonance image data.

A method of performing bariatric surgery using a robotic surgical system includes positioning a gastrectomy device in a selected location in a stomach; applying an adherent material to the stomach along a desired transection line; and cutting the stomach along the desired transection line delineated by the adherent material.

An indwelling clip includes a clip main body having a pair of arm plate portions that can be opened in a substantially V shape with an elastic force and claw portions formed on respective tip portions of the arm plate portions. The indwelling clip also includes a fastening ring attached to the arm plate portions so as to be movable along a longitudinal direction of the pair of arm plate portions and be able to close the pair of arm plate portions by moving in a direction of the claw portions. An outer surface of the claw portion is provided with a fluorescent body containing a fluorescent pigment emitting red or near infrared light by being irradiated with excitation light.

A stable affixation system for dental implantation includes a fixation tray having, for rapid placement, a housing defining a chamber whose inner surface is configured to house a flowable or malleable material (configured to harden) and be placed over one or more teeth during guided dental implantation surgery. A mechanism for urging the material against the teeth may comprise side walls having an inwardly directed extra flexible arm extension or an inwardly directed step. A lock mechanism may comprise a wedge positioned over the fixation tray to reduce or eliminate freedom of movement of the tray. For rapid removal, the system may include mechanisms (for example an element rotating inside the tray) for applying force on the tray and material and for ensuring that the material adheres more strongly to the tray than to the teeth. The system is sturdy enough to withstand forces including from various angles and leverage.

An indwelling clip includes a pair of arm plate portions that can be opened in a substantially V shape with an elastic force and claw portions formed on respective tip portions of the arm plate portions. The indwelling clip also includes a fastening ring attached to the arm plate portions so as to be movable along a longitudinal direction of the pair of arm plate portions and be able to close the pair of arm plate portions by moving in a direction toward the claw portions. The arm plate portion is provided with a fluorescent body containing a fluorescent pigment emitting red or near infrared light by being irradiated with excitation light. According to some embodiments, the indwelling clip allows easy visual recognition of light emission of a fluorescent body from the outside of a hollow organ and enables excellent attachment stability to the inner wall of the hollow organ.

A tissue segmentation device, controller, and methods therefore are disclosed. The device has an active electrode, a return electrode, a mechanical force application mechanism, voltage and current sensors, and a controller. The controller has a processing component, configured to assign a circuit status to a circuit comprising the at least one electrode. IF (PF0) and ((Vrms/Irms)T), THEN the circuit status is open. IF (PF0) and ((Vrms/Irms)<T), THEN the circuit status is short. PF is a power factor of power applied to the electrosurgical device. T is a threshold value.

A surgical instrument for treating the tissue of a patient is disclosed. The surgical instrument comprises a housing including a handle, a housing frame comprising a housing connector, and a drive system comprising at least one electric motor. The surgical instrument further comprises a shaft assembly releasably assembled to the housing including a shaft frame comprising a proximal connector and a distal connector, wherein the proximal connector is releasably coupled to the housing connector and a shaft drive system comprising at least one rotatable shaft operably coupled to the electric motor. The surgical instrument further comprises an end effector releasably assembled to the shaft assembly including an end effector frame comprising an end effector connector releasably coupled to the distal connector of the shaft assembly, a plurality of staple cartridges removably stored in the end effector, and a plurality of end effector drivers operably coupled to the rotatable shaft.
