A surgical instrument (100) for placement of a movement restriction device (10) for use in a surgical procedure for treating reflux disease in a patient. The instrument comprises a sleeve (113) and a holding device (111) configured to engage the movement restriction device, wherein the holding device is configured to be placed within the sleeve and be displaceable in relation to the sleeve. The instrument further comprises a first handling portion (101) connected to the sleeve, and a second handling portion (102) connected to the holding device. The handling of at least one of the first and second handling portion creates relative displacement of the holding device in relation to the sleeve, which disengages the holding device from the movement restriction device for performing the placement of the movement restriction device.

A surgical instrument includes an end effector, and a shaft assembly. The end effector includes an ultrasonic blade, a rotating body, and a clamp arm movable between an open and a closed position. The shaft assembly extends along an axis and includes clamp arm clocking assembly and a clamp arm pivot assembly. The clamp arm clocking assembly can drive the rotating body and the clamp arm between a first clocked position and a second clocked position. The clamp arm pivot assembly includes an actuator body defining a track, where the actuator body can actuate to drive the clamp arm between the open position and the closed position while the actuator body is in a rotational position relative to the ultrasonic blade. The track houses a portion of the clamp arm in the first clocked position and the second clocked position while the actuator body is in the rotational position.

A tool for surgically removing tissue of a patient includes a body, a flexible rotating shaft that drives a distal cutting tool and is drivingly coupled to a motor supported by bearings in a flexible tubular sheath to allow the shaft to rotate and be shifted longitudinally. Steering cables in the sheath control the flexion of the sheath. A processor controls the operation to ensure that the cutting tool operates within a predetermined resection area, controlling a combination of motor speed, sheath flexion, and shaft retraction to assist surgery in the resection area.

Provided herein are methods of analyzing tissue using a magnetic resonance imaging (MRI) compatible tissue analysis device that includes radio¬frequency (RF) tracking and imaging elements. Related kits, systems, and computer program products are also provided.

Systems, devices, and methods for providing an endoluminal transhepatic access to a patient pancreaticobiliary system in an endoscopic procedure are disclosed. An example of a transhepatic access procedure comprises navigating a steerable elongate instrument through a body cavity or channel and exiting to a access site of liver, puncturing the liver from the access site, extending the steerable elongate instrument through the liver and into the pancreaticobiliary system and performing an operation therein. Following the operation, the steerable elongate instrument can be retreated, and the access site of liver can be closed with a closure means. Apparatus and methods of training a machine-learning model and using said model to identify patient candidacy for retrograde access based on images of patient anatomy are also disclosed.

An external endoluminal fixator device to fix rectal prolapse and/or vaginal and/or uterine and/or urinary bladder prolapse by passing through it, includes a head configured at distal end of the external endoluminal fixator device such that the head passes through an anorectum or a vagina of a body. The device then includes a hollow shaft connected with the head which is in angulation corresponding to usage in the anorectum or a sacral hollow or the vagina of the body and an endoluminal fixator device handle connected with the hollow shaft at proximal end of the external endoluminal fixator device, configured to remain outside of anus or vagina to have a sturdy grip so as to push up the head of the endoluminal fixator device either trans-anally or vaginally with the anorectum or the vagina against undersurface of the anterior abdominal wall.

A patient's stomach may be secured to the patient's diaphragm. A method to accomplish this includes visualizing a wall of a patient's stomach adjacent the patient's diaphragm from within the patient's stomach, inserting a fastener deployment apparatus down the patient's esophagus and into the mammalian's stomach, and fastening the patient's stomach to the patient's diaphragm with the fastener deployment apparatus and from within the stomach. The procedure may be employed to advantage to treat a hiatal hernia, for example, either alone or in conjunction with the restoration of the patient's gastroesophageal flap valve.

A surgical instrument includes a handle with a main body having a central axis, a lever pivotable around a pivot axis fixed with respect to the main body. The lever includes a finger abutment section including a lower finger rest contacting the ventral sides of a user's first and second fingers during pivoting movement of the finger abutment section towards the central axis, and an upper finger rest contacting the dorsal sides of both the fingers during pivoting movement of the finger abutment section away from the central axis; and a septum fixed to lower and upper finger rests and extending therebetween forming a separate first and second finger receiving portion for respectively receiving a first and a second fingers. The lever pivots around the pivot axis such that during pivoting of the lever, the septum central plane remains substantially coplanar with a plane parallel to the central axis.

Certain aspects of the present disclosure provide methods and apparatus for managing an esophagus of a subject during a medical procedure, such as cardiac tissue ablation or bronchial tissue ablation. Managing the esophagus may include displacing the esophagus, imaging the esophagus, and/or measuring temperature at one or more locations inside the esophagus. One example esophageal management system generally includes a tube configured for insertion through a mouth and into the esophagus of the subject. The tube generally includes a first port located at a proximal end of the tube and in fluid communication with a distal portion of the tube via a first path, a second port located at the proximal end of the tube, and a third port located between the proximal end of the tube and a distal end of the tube and in fluid communication with the second port via a second path.

This application is directed to a medical instrument with a hollow shaft, an actuating unit at the proximal end and an instrument tip with an instrument at the distal end, wherein the instrument can be actuated via an actuating element in the shaft, the element being in an connection with the actuating unit and the instrument tip being pivotable via a joint mechanism, the joint mechanism having pivoting members connected with a proximal-side drive via steering wires running in the direction of the shaft in such a way that movement of the proximal-side drive causes a corresponding movement of the distal-side pivoting members and a pivoting of the instrument tip and wherein the proximal-side drive includes a spatially adjustable disk on which the steering wires are mounted. In order that the steering wires may be controlled precisely and reproducibly, the drive for the spatially adjustable disk is a motorized drive.
