A distraction system can include a distraction implant comprising a magnetic element and a distraction mechanism configured to expand the distraction implant in response to rotation of the magnetic element. The distraction system can include an external device comprising a motor configured to rotate a driver magnet while in a powered state, the driver magnet configured to rotate the magnetic element, a computing device configured. The computing device can be configured to measure an electrical current drawn by the motor during rotation of the driver magnet. The computing device can be configured to maintain the motor in the powered state in response to a mean value of the electrical current being greater than or equal to a mean value threshold, and a standard deviation value of the electrical current being less than or equal to a standard deviation threshold.

A plurality of structures that resiliently attract one another are provided for implanting in a patient around a body tissue structure of the patient. For example, the body tissue structure may be the esophagus, and the plurality of structures may be implanted in an annulus around the outside of the esophagus, the annulus being substantially coaxial with the esophagus. The attraction may be between annularly adjacent ones of the structures in the annulus, and it may be provided, for example, by magnets or springs. The array of structures is preferably self-limiting with respect to the smallest area that it can encompass, and this smallest area is preferably large enough to prevent the apparatus from applying excessive pressure to tissue passing through that area.

Embodiments are directed to a medical robot system including a robot coupled to an end-effectuator element with the robot configured to control movement and positioning of the end-effectuator in relation to the patient. One embodiment is a method for removing bone with a robot system comprising: taking a two-dimensional slice through a computed tomography scan volume of target anatomy; placing a perimeter on a pathway to the target anatomy; and controlling a drill assembly with the robot system to remove bone along the pathway in the intersection of the perimeter and the two-dimensional slice.

A method and system for use in surgery, which includes a grasper having a jaw, and a grasper housing having a proximal end and distal end and defining a docking opening, and a tool having a tool housing having a proximal end, a distal end and defining an inner surface, and a robotic device operably coupled to the proximal end of the grasper housing, and configured to actuate the jaw of the grasper. The tool housing having an operative assembly at the distal end of the tool housing, and the tool housing defining a docking assembly at the proximal end of the tool housing. The operative assembly having a fulcrum operably coupled to the tool housing, a first lever operably connected to the fulcrum, an instrument operably coupled to the first lever, and an actuator operably coupled to the tool housing and the first lever.

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.

Systems and methods for removing a material from a lumen or duct include a guide wire to navigate to the material and a cutting assembly that can then be guided along the guide wire to reach the material. A proximal wire end can be connected to a pump device configured to provide an irrigation substance along a delivery channel of the guide wire and release the irrigation substance at a distal wire end. A power source can apply a current to the guide wire to magnetize a coupling assembly disposed on the guide wire. The cutting assembly can couple to the guide wire by engaging a locking mechanism of the cutting assembly with a coupling assembly of the guide wire. The locking mechanism can receive torque provided by a motor coupled to the proximal wire end of the guide wire to rotate the cutting tool of the cutting assembly to remove the material.

Embodiments of the disclosure include a tissue and/or access device that allows for adjustability of placement of a needle for accessing a blood vessel of an individual in need thereof, particularly when used with an imaging device. The adjustability originates from both angle of the needle for insertion into the body of the individual and longitudinal placement of the needle on the body of the individual. In specific embodiments, a needle guide through which the needle traverses is detachable.

A surgical tool for use with a robotic system that includes a tool drive assembly that is operatively coupled to a control unit of the robotic system that is operable by inputs from an operator and is configured to robotically-generate output motions. A drive system is configured to interface with a corresponding portion of the tool drive assembly for receiving the robotically-generated output motions and applying the output motions to a drive shaft assembly which is configured to apply control motions to a surgical end effector operably coupled thereto. A manually-actuatable control system operably interfaces with the drive shaft assembly to facilitate the selective application of manually-generated control motions to the drive shaft assembly.

A magnetizer system for use with a medical device including ferrous elements. The magnetizer can include a magnetizer body defining a cavity, the magnetizer body having a body opening in communication with the cavity, the magnetizer body including one or more magnets configured to generate a magnetic field configured to imprint a magnetic signature on ferrous elements within the cavity. The magnetizer can include one or more mechanisms configured to detect the presence of the medical device.

A method for adjusting the operation of a surgical instrument using machine learning in a surgical suite is disclosed.
