An anastomotic ring device for forming a hollow rivet (ring) attachment between tissue lumens facilitates laparoscopic or endoscopic implantation by including features that facilitate actuation from a stressed, generally cylindrical shape. Economical manufacturer is achieved by weaving open ended strands into a generally cylindrical stent shape that is imparted with a Shape Memory Effect (SME) to actuate to a hollow rivet (ring) shape. Alternatively or in addition to SME inherent in the woven strands, an actuating force may be received from a helical spring element incorporated into the ring. Self-actuating ring devices are enhanced by forming woven strands into petals that diverge from opposing petals such that the strands encounter less friction when actuating. Each of these features alone or in combination enhance clinical use of anastomotic ring devices, such as a bariatric gastric bypass procedure.

The invention is directed to a suture clinch that may be placed upon suture extensions of a placed suture to securely lock the extensions in a desired location. The clinch operates to replace a tied knot and retain the suture in a fixed relationship with little or no damage to the suture itself. The clinch comprises a mating pair of interlocking members that restrict movements of the suture. The interlocking members may be placed upon the suture extensions from alongside the suture extensions and compressed to a first condition where the interlocking members may be advanced, retracted or adjusted, and subsequently further compressed to a second condition where the interlocking members are fully engaged to fully restrict the movement of the suture. In another aspect, the clinch may be provided in a flat form comprising a first component and a second component. The first and second components fit together in a mating relationship that entraps at least a portion of the suture between tractive faces of the first and second components, respectively. Each end of the first and second components may have a recessed central portion that leaves two extensions along the sides of each end of the components. The extensions of the second component are subsequently folded over the first component to provide secure entrapment of the suture between the tractive faces of the first and second components. The tractive faces operate to engage the suture and hold it securely in place without damaging or challenging the suture. The clinch may comprise of plastic, metallic materials such as stainless steel or titanium, or a combination of both where the plastic is chosen for its value as an atraumatic interface and the metal for its radiopacity or durability.

A stent delivery system includes a stent having at least one eyelet and at least one rivet and a holder supporting the stent, wherein the holder includes a first section having a first diameter and a second section having a second diameter. A sheath covers the stent and the holder. The rivets are attached to each of the eyelets. A first inner diameter of the stent at the position of the rivets is smaller than a second inner diameter of the stent at other positions because the rivets protrude inwardly. A shoulder is formed on the holder due to the difference between the first diameter and the second diameter of the holder. The shoulder is positioned distally adjacent the rivets. The shoulder interferes with the protruding rivets, thereby restraining the longitudinal movement of the stent relative to the holder. Although the sheath is pulled back, the stent does not jump out of the stent delivery system. As a result, the stent delivery system allows the stent to be released in a controlled manner upon its deployment.

Improved method and apparatus for interlocking hemmed together edges of inner and outer vehicle body panels with an improved interlock joint. The inner panel blank is draw stamped and provided with PLP holes in a stamping press. A plurality of conventional hardware components are then welded to the inner panel. Then interlock holes are formed by a piercing tool moving through the inner panel border from its outboard to its inboard side while the inner panel is held by clamps and PLP pins. The hole piercing punch thus leaves cold worked upset material slightly raised inboard, rather than outboard, around the pierced interlock hole margin. Then the inner panel subassembly is married to the outer panel and transferred to a hemming station and again precisely clamped and positioned by PLP pins, whereupon hemming press gates are operable for hemming the flange lip of the outer panel over the inner panel border. The final hemming steel of each gate carries staking punches that individually strike a precision registered portion of such hemmed lip to deform it into locking engagement with the associated interlock hole. The upset material is thus flattened and accurately worked into embedment into the interior surface of the hemmed flange lip, rather than into the interior surface of the outer panel, thereby avoiding creating read through problems on the outer panel.

There is provided method for joining dissimilar metals of a steel product and a light metal product with each other, wherein the light metal product and a rivet made of an iron-base metal are connected with each other beforehand in a previous process preceding spot welding, and subsequently, the rivet and the steel product are spot welded with each other. Then, a cavity for use in clinching the light metal product is formed, and upon the stem of the rivet is embedded into the light metal product to penetrate therethrough, light metal is caused to undergo plastic flow into the cavity of the rivet, for clinching the light metal product to be thereby clinched with the rivet whereupon spot welding for forming a weld nugget only within the scope of an interface between the stem of the rivet, and the steel product is carried out. Thus, the present invention can implement the spot welding between iron—iron similar metals, without a constraint on, and a problem with conditions applicable to the spot welding and a high joint strength can be obtained owing to the synergistic effect of the spot welding and connection by clinching of the aluminum alloy product with the iron-base rivet, added thereto.

Automotive load cells having centralized, multi-axis, loose tolerance overload/limit stops provide improved strain gauge response. The modular, integrated stop assemblies magnify sensor substrate deflection by use of opposed concave (Belleville) springs are used in direct contact with the substrate to accommodate ±Z axis deflection and Mx/My moment angular rotation. A flanged guide member on the load stud permits a wide range of geometries. The substrate is thickened around the load stud hole and the outboard support bolt holes. Hollow rivets assist in design modularity. Strain gauges are placed at the yield zones symmetrically with respect to the X axis. The substrate hole Mx/My gap is larger than the stop bracket hole to insure a positive stop for Mx/My moments prior to yield. The inventive multi-axis stop assembly is used in any type load cell, including rectangular, thinned, notched, necked/dogbone, or cantilever substrates with any strain gauge layout configuration.
