Methods and devices described herein facilitate improved access of locations within the body by providing a variety of dissection modes on a single access device.

A medical manipulator system includes a manipulator, an operating unit for entering operation commands, motors for actuating a working unit, and a controller for energizing the motors based on operation commands supplied from the operating unit. When an activation resetting switch and a resetting switch are operated according to a predetermined procedure, the controller performs a resetting process to return the motors to an origin. The controller is capable of controlling three manipulators. The activation resetting switch is shared by the three manipulators, and there are three resetting switches corresponding to the three manipulators.

An endoscopic instrument comprises a shaft, comprising a proximal end and a distal end. A grip comprising a handle is arranged at said proximal end of said shaft and a tool having at least an open and a closed position is arranged at said distal end of said shaft. Said shaft comprises at least two sections, a first section and a second section, which can be articulated with respect to said first section. Said second section comprises said tool. Said instrument further comprises an actuating element, by means of which said handle is in operative connection with said second section and with which an articulation of said second section can be initiated. Said first section or said actuating element and said tool are connected by a control element, by means of which said tool can be moved back and forth between said closed position and said open position in the course of an articulation of said second section, such that both the articulation of said second section and an opening / closing of said tool can be accomplished by the movement of said actuating element.

Surgical instrument with wireless communication between control unit and sensor transponders. The surgical instrument (10), such as an endoscopic or laparoscopic instrument, comprising, according to various embodiments, an end effector (12) comprising at least one sensor transponder (368). The surgical instrument also comprises a shaft (8) having a distal end connected to the end effector (12) and a handle (6) connected to a proximate end of the shaft (8). The handle (6) comprises a control unit (300) in communication with the sensor transponder (368) via at least one inductive coupling (302,320,324). The surgical instrument (10) may be a power assist motorized device including a battery for powering (at least partially) the surgical instrument (10) during use. The surgical instrument (10) may be adapted to provide user feedback regarding the load being experienced by the end effector.

Devices and methods for improving the function of a valve (e.g., mitral valve) by positioning a spacing filling device outside and adjacent the heart wall such that the device applies an inward force against the heart wall acting on the valve. A substantially equal and opposite force may be provided by securing the device to the heart wall, and / or a substantially equal and opposite outward force may be applied against anatomical structure outside the heart wall. The inward force is sufficient to change the function of the valve, and may increase coaptation of the leaflets, for example. The space filling device may be implanted by a surgical approach, a transthoracic approach, or a transluminal approach, for example. The space filling portion may be delivered utilizing a delivery catheter navigated via the selected approach, and the space filling portion may be expandable between a smaller delivery configuration and a larger deployed configuration.

Devices and methods for improving the function of a valve (e.g., mitral valve) by positioning an implantable device outside and adjacent the heart wall such that the device alters the shape of the heart wall acting on the valve. The implantable device may alter the shape of the heart wall acting on the valve by applying an inward force and / or by circumferential shortening (cinching). The shape change of the heart wall acting on the valve is sufficient to change the function of the valve, and may increase coaptation of the leaflets, for example, to reduce regurgitation.

A system according to the present invention helps to reduce consumption of food by a patient. In one aspect, the system includes a banding apparatus which may be applied to around part of a patient's stomach to reduce that part to a reduced diameter. Another aspect provides wrapping apparatus that may extend from the banding apparatus and around an upper pouch of the stomach to inhibit expansion of the upper pouch beyond a predetermined volume. The wrapping apparatus further may be anchored relative to part of the patient's body to mitigate diaphragmatic hernia.

A surgical ring (1) designed to be implanted around (a) biological organ(s), the ring (1) being formed by a flexible band (2) including a first and second extremity (3, 4), the flexible band (2) being designed to be closed near its two extremities (3, 4) by a closure system so as to form a closed loop featuring an internal contact surface (2A) external 10 surface (2B). The closure system includes a means of encircling (5) that is integral with the first extremity (3) and arranged to evolve between a de-latching configuration, where the means of encircling (5) forms an open collar freeing the second extremity (4), and a latching configuration where the means of encircling (5) forms a closed collar designed to surround the second extremity (4) so as to unite it with the first extremity (3), the closed collar having opposite front (6) and rear (7) faces, between which an encircling opening extends that is designed to accept the second extremity (4).
