A surgical apparatus system for minimally invasive surgery (MIS) which includes a wrist assembly. The wrist assembly includes a first jaw, a first actuation hub, and a cable redirecting hub operably coupled to the first actuation hub, a second jaw, a second actuation hub, a housing for the first and second jaws, a first cable, a second cable, a third cable, rotational position sensors, and a control system. The first and second jaws of the wrist assembly are movably opposed, and the cables are configured such that applying tensions upon them cables produces rotation about a jaw axis. The wrist assembly may further include a hinge-rotary assembly to configured to provide rotation about a pitch axis and/or a roll axis. The wrist assembly may further include a fourth cable configured such that applying tensions upon the fourth cable and the opposing cable produces rotation about a pitch axis.

A system for crushing and/or removing body stones, includes a source causing shock waves and/or ultrasonic waves, and a probe, wherein the source and the probe are reversibly connectable to one another via an interface for transmitting the shock waves and/or ultrasonic waves to the probe. The probe includes an identification element for identifying the probe, the identification element being arranged in or on the probe in a sound-protected manner. The identification element is preferably an RFID element.

An apparatus includes an occlusion device operable to fit securely in an anatomical passageway within a head of a human. The occlusion device is configured to move unitarily with the head when the occlusion device is installed in the anatomical passageway. The occlusion device is further configured to prevent passage of fluid through the anatomical passageway when the occlusion device is installed in the anatomical passageway. A position sensor is fixedly integrated into the occlusion device. The position sensor generates signals indicating a position of the occlusion device in three-dimensional space, thereby indicating the position of the head in three-dimensional space. A connector communicatively coupled to the position sensor is operable to receive and transmit the signals generated by the position sensor.

Systems and methods for forming an anastomosis between two adjacent walls of a digestive tract are provided. The system can include a first and second magnetic implants that are configured to magnetically couple to each other through the two adjacent walls of the digestive tract to compress a portion of the two adjacent walls therebetween and form a necrotic area that becomes surrounded by a scarred edge following a healing time period. The system can also include a retention member that can extend outwardly from a corresponding one of the first and second magnetic implants, the retention member being configured to retain the first and second magnetic implants in position and prevent passage thereof through the necrotic area during the healing time period.

A surgical instrument includes a shaft defining an axis, an end effector coupled to a distal portion thereof, a fixed handle coupled to a proximal portion thereof, a drive bar, a movable handle, and a linkage. The drive bar is disposed within the shaft and operably coupled to the end effector. The movable handle is movable relative to the fixed handle between open and closed positions and is coupled to the drive bar via a first pin on the axis. The linkage includes a first end portion coupled to the movable handle via a second pin and a second end portion coupled to the shaft via a third pin on the axis. In the closed position of the movable handle, the second pin is disposed in a near-over-center position relative to the axis to reduce a force necessary to maintain the movable handle in the closed position.

A vascular closure device configured to seal a puncture site in the vessel wall in a more efficient manner is disclosed. The vascular closure device includes a guide member that extends through a portion of the sealing device and that is removable from the portion the sealing device.

A disposable bidirectional ratchet, which has a tubular hollow handle with an interior surface having teeth thereon; a toggle mounted movably within the handle; a knob connected to an end of the toggle moves the toggle inside the handle; a plurality of pins on another end of the toggle; a plurality of actuators each comprising: fingers, levers, toes and a head, and having a post guide formed therein; a plurality of posts affixed to a clutch; and, wherein the actuators are movable affixed to the clutch via the posts, and the pin position selects the direction of engagement via adjustment of the actuator position via applying force to the levers, which moves the lateral edges of the actuator towards or away from the teeth.

Drug delivery articles, resident articles, and retrieval systems e.g., for gram-level dosing, are generally provided. In some embodiments, the articles are configured for transesophageal administration, transesophageal retrieval, and/or gastric retention to/in a subject. In certain embodiments, the article includes dimensions configured for transesophageal administration with a gastric resident system. In some cases, the article may be configured to control drug release e.g., with zero-order drug kinetics with no potential for burst release for weeks to months. In some embodiments, the articles described herein comprise biocompatible materials and/or are safe for gastric retention. In certain embodiments, the article includes dimensions configured for transesophageal retrieval. In some cases, the articles described herein may comprise relatively large doses of drug (e.g., greater than or equal to 1 gram).

A method and system of bending medical device components for customization to a particular medical procedure and patient while generally maintaining the ideal performance of the component. A medical professional embeds the medical device component into a bending tool. The medical professional then aligns an intended curve region of the medical device component within a bending region of the bending tool and imparts a curve in the bending region. Finally, the medical professional withdraws the medical device component from the bending tool, and utilizes the bent medical device component in the medical procedure. The system may be a kit comprising various medical device components for a particular medical procedure and a suitable bending tool for those components.
