An endoscopic surgical cutting stapler with a chain articulation is provided, in which a joint is implemented by a chain articulation, teeth are provided at two ends of a chain plate of the chain articulation, and teeth of adjacent chain plates in the same row are engaged. Through mesh transmission of engaged teeth of the adjacent chain plates in the same row, an angle of a most proximal chain plate of the chain articulation is gradually multiplied at several stages and transmitted to an end effector. The end effector can rotate for 90° with small drive motion of the operating mechanism, thereby achieving precise placement of the chain articulation after rotation. The end effector can be precisely aligned with a part to be cut and stapled, and a radius of curvature of the chain articulation can be significantly increased.

Robotic and / or surgical devices, systems, and methods include kinematic linkage structures and associated control systems configured to facilitate preparation of the system for use. One or more kinematic linkage sub-systems may include joints that are actively driven, passive, or a mix of both. A set-up mode employs an intuitive user interface in which one or more joints are initially held static by a brake or joint drive system. The user may articulate the joint(s) by manually pushing against the linkage with a force, torque, or the like that exceeds a manual articulation threshold. Articulation of the moving joints is facilitated by modifying the signals transmitted to the brake or drive system. The system may sense completion of the reconfiguration from a velocity of the joint(s) falling below a threshold, optionally for a desired dwell time. The system may provide a detent-like manual articulation that is not limited to mechanically pre-defined detent joint configurations. Embodiments of the invention provide, and can be particularly well-suited for manual movement of a platform supporting a plurality of surgical manipulators in a robotic surgical system or the like without having to add additional input devices.

A stent-graft having an exo-skeleton attached to a tubular graft, the tubular graft having a peripheral wall defining a lumen therein extending between first and second ends. The exo-skeleton may assume contracted and enlarged conditions, and includes one or more serpentine elements, each extending both peripherally and axially along at least a portion of the peripheral wall. Coiled-sheet stents are provided on the ends of the tubular graft for anchoring the ends within a body passage. Each serpentine element is a zigzag structure extending peripherally about the peripheral wall, with a plurality of serpentine elements distributed axially along the peripheral wall. The serpentine elements are individually attached to the peripheral wall and / or connector elements may extend between adjacent serpentine elements. Alternatively, each serpentine element may define a generally sinusoidal shape extending axially along the peripheral wall. The tubular graft may have a bifurcated end from which a tubular graft extension segment may extend and to which a docking limb may be attached. A plurality of serpentine elements may also be attached to the extension segment and the docking limb.

An improved four-bar hinge assembly for attaching a trunk deck lid to a vehicle body in which the control link of the four-bar linkage has its usual vehicle-mounted pivot pin replaced by the rotatably driven output drive shaft of a power drive mechanism that is rigidly and directly coupled to the control link to swing to the same and thereby power actuate the four-bar linkage in order to pivot the deck lid between open and closed positions. The hinge elements are located on the weather side of the vehicle body components and the drive shaft extends through the vehicle sheet metal into the weather sealed trunk compartment so that the electro-mechanical drive components are mounted within the weather sealed trunk.

A drive shaft assembly for a downhole motor includes a drive shaft formed with convexly spherical bearing surfaces on each end, and end housings with concavely spherical bearing surfaces for mating contact with the spherical bearing surfaces of the drive shaft, thereby facilitating omni-directional articulation between the drive shaft and the end housings while transferring axial thrust loads between the drive shaft and end housings across the interface of the mating spherical bearing surfaces. Torque is transferred between the drive shaft and end housings through two or alternatively four swivelling drive keys mounted to each end of the drive shaft and engageable with complementary drive key slots in the end housings. Full and constant torque-transferring contact is thus provided between the swivelling drive keys and the end housings irrespective of any angular offset between the drive shaft and the end housings, resulting from omni-directional articulation of the drive shaft relative to the end housing. The omni-directional center of rotation at each end of the drive shaft coincides with the geometric centerpoint of the corresponding convexly spherical bearing surface, which corresponds to the intersection of the drive shaft's rotational axis, the end housing's rotational axis, and the drive key swivel axis.

A catheter capable of articulating in two and three directions is provided. Articulation at the distal tip of the catheter is facilitated by applying selective tension on a steering wire disposed in a lumen that resides peripheral to a central working lumen. Tension on the steering wire through the peripheral lumen causes the catheter tip to bend while the central working lumen resists compression.

Devices and methods for preventing knee sprain injuries. To protect the knee joint from knee sprain injuries, the device comprises a sensing part configured to sense data associated with knee motion; an analyzing part configured to analyze the knee motion data to determine a knee articulation; and a stimulating part configured to stimulate one or more lower limb muscles to initiate an earlier muscle reaction than would naturally occur in response to the determined knee joint articulation. The determined knee joint articulation may include knee joint articulation or a particular type of articulation such as a knee sprain movement associated with knee sprain. The methods involve sensing data associated with knee joint motion, analyzing the data to determine a knee joint articulation; and stimulating one or more lower limb muscles to initiate an early muscle reaction within the determined knee joint articulation.

Exemplary embodiments of devices and method for affecting at least one anatomical tissue can be provided. A configuration can be provided that includes a structure which is expandable (i) having and / or (ii) forming at least one opening or a working space through which the anatomical tissue(s) is placed in the structure. For example, the structure, prior to being expanding, can have at least one partially rigid portion. In addition, or as an alternative, upon a partial or complete expansion thereof, the structure can be controllable to have a plurality of shapes. Further, the structure can be controllable to provide the working space with multiple shapes and / or multiple sizes.

It is constituted on the basis of a tongue (1) which is conveniently attached to the boot, which is divided into a number of sectors (3), in which are some receptacles (5) which hold sheets (6) of material resistant to impact and ductile in order to facilitate the adaptation thereof to the form of the boot when closed. The sectors (3) are delimited by some lines of stitching (4) which facilitate the relative inclination between sectors (3) and therefore the articulation of the tongue (1) when the boot is flexed achieving greater user comfort.

The present invention relates a vascular prosthesis and related assembly methods that includes a plurality of modular segments inter-engaged by flexible, and preferably lockable, inter-engageable elements forming joints or other connector areas. The segments may have a number of different mechanical properties and may be assembled by the clinician, through mechanical or chemical joining, to customize the prosthesis for a specific patient or application.
