  • Patent number: 9744021
    Abstract: Devices, systems, and methods for implanting radially expandable prostheses in the body lumens rely on tacking or anchoring the prostheses with separately introduced fasteners. The prostheses may be self-expanding or balloon expandable, and may include a single lumen or more than one lumen. After initial placement, a fastener applier system is introduced within the expanded prostheses to deploy a plurality of fasteners to at least one prosthesis end. The fasteners are usually helical fasteners which are releasably restrained on the fastener driver, and are delivered by rotation of the fastener driver. The fasteners may be applied singly, typically in circumferentially spaced-apart patterns about the interior of at least one end of the prosthesis. A lumen extension or lumens may be coupled to the prosthesis to extend the reach of the prosthesis within the implantation site. Fasteners may also be applied to the lumen extensions.

    Abstract: A rivet includes a sleeve, which has a flange, and a core member, which is inserted into the sleeve. The distal end of the sleeve is coupled to a plurality of pivoting pieces via thin hinges. By inserting the core member into the sleeve, each pivoting piece is pushed against the core member to pivot outward, and a laminated member, which is located between the flange and each pivoting piece, is fixed. A projection is arranged on the basal end surface of each pivoting piece. A hook portion is arranged on the head of the core member to project radially outward of the core member. When the core member is inserted into the sleeve, the hook portion of the core member moves past the projection of each pivoting piece in an outwardly pivoted state to fix the pivoting piece.

The sleeve has a toggle opening so that the toggle can rotate from a first position in which the toggle is substantially located within the sleeve to a second position in which surface engaging portions of the toggle extend beyond the sleeve. A lower portion of the sleeve has a toggle rotation surface to facilitate rotation of the toggle.

  • Patent number: 5798021
    Abstract: A clamping apparatus for use in clamping a fitting to a pipe or other fitting. The apparatus may be used without supporting the outer surface of the pipe on the opposite side of the fitting, and in the case of a buried pipe, only a portion of the pipe needs to be excavated. The apparatus comprises a clamping plate for engaging an outer surface of the fitting with an adjusting stem threadingly engaged with the clamping plate. A locking bar is pivotally and rotatably attached to an end of the adjusting stem. A weight differential between long and short ends of said locking bar and a cable are used to pivot the locking bar between a first position thereof wherein the locking bar and a portion of the stem may be inserted through aligned openings in the fitting and pipe and a second position.

  • Patent number: 5535570
    Abstract: A wall anchor comprising the combination of a round locking nut and a unique swing-toggle holds a greater weight, while using a smaller drill hole, than existing with typical toggle bolt anchors. The swing-toggle is generally in the configuration of a cylinder, inwardly sliced open from both its opposing ends an arc distance greater than the diameter of the toggle bolt being accommodated and a length to still allow flush and fast securement behind the wall. A pair of projections inwardly facing from the cylinder walls seat between adjacent threads of the toggle bolt in facilitating the securement, while their placement allows for a downwardly pivoting of the swing-toggle once the anchor is inserted through the drill hole in the wall.

  • Patent number: 5507611
    Abstract: A key bolt fastener has a shank with a locking key-receiving adaptation at one end. The locking key is shaped like a tweezers, having a first end that joins two arms in a resilient fashion, and a bifurcate second end in which the ends of the two arms are normally in spaced apart relationship. When the locking key is retained to the key-receiving adaptation by a pin transversely disposed in the shank and passing through slots in the arms at substantially right angles, the locking key is slidable within the adaptation to an unlocked position where the first end of the locking key extends directly outwardly of the shank and forms an extension thereof. The locking key is also slidable to a locked position wherein the locking key is substantially perpendicular to the shank and a key lock abuts the bolt shank to retain the locking key in locked position. The locking key is yieldable at the bifurcate second end to enable the key lock abutment to be moved from locked position to unlocked position.

  • Patent number: 5499894
    Abstract: A keybolt (40) includes a bolt member (10) and a key member (12). The key member includes a first leg (22) and a second leg (24) which are biased apart. The first leg includes steps (21) thereon. The key member is rotationally and slidably movable in a recess (20) on said bolt member. The key member is held in said recess by a rivet (14) which extends through elongated channels (42) in the leg members. The key member is movable between a locked position in which it extends generally traversely of the axis of the bolt member so as to hold the keybolt in an aperture through which it extends. The key member is movable to an unlocked position wherein it is rotatable to extend coaxially with the bolt member and wherein the keybolt may be readily installed or removed from appropriately sized apertures.

  • Patent number: 5464311
    Abstract: A blind bolt comprising a headed bolt with a male screw at the side opposite its head having an external diameter which can be inserted into through-holes of architecture members to be tightened; a rotating washer made of a cylindrical member having an external diameter which can be inserted into the through-holes of architecture members, and having on both end surfaces slopes in parallel to each other each of which has a longitudinal diameter larger than that of the internal diameter of each of said architecture members; and a nut which is screwed to the male screw. Thus, the blind bolt can be inserted into through-holes of architecture members from one side and also can be nut-tightened from the same one side thereby tightening the architecture members.

  • Patent number: 5376097
    Abstract: A fastening system device having dimensions of very small magnitudes for attaching a mesh prosthesis or tissue to body tissue. The device has a shaft member which has a continuous outer peripheral surface and so constructed such that the outer surface is a continuous surface and has a continuous curved cross-section where the center of curvature is in the radial direction of the longitudinal axis; the shaft has sufficient columnar resistance to bending to permit the shaft member to penetrate body tissue. A head member extends radially from the shaft member at a second end and is so dimensioned and proportioned to form a bearing surface for bearing against the mesh prosthesis. A resiliently collapsible anchor member is integrally fixed to the first end of the shaft and separately forms a conical distal tip.

  • Patent number: 5244324
    Abstract: A number of improvements to anchoring retainers are disclosed. The improvements ensure that the retainers are securely attached to walls, and that they do not move during attachment after being attached by a threaded fastener. In one inventive feature, an improved cap for securing the fastener to the wall is disclosed wherein the cap has a thickened portion. In another feature, flip caps are disclosed which secure the anchor within a bore in the wall. In an additional feature of the invention, a tab and groove engagement insures that portions of the retainer do not move relative to each other as the threaded fastener is tightened. Finally, in another feature of the invention, structure is included into the retainer which assists the retainer in folding towards a secured position in the wall.
