  • Patent number: 7001400
    Abstract: Devices, systems, and methods for suturing of body lumens allow the suturing of vascular puncture sites located at the distal end of a percutaneous tissue tract. An elongated articulated foot near a distal end of a shaft is inserted through the penetration and actuated so that the foot extends along the lumenal axis. The foot carries suturing attachment cuffs, and needles are advanced from the shaft through the vessel wall outside of the penetration and into engagement with the needle cuffs after the foot has been drawn proximally up against the endothelial surface of the blood vessel. The cross-section of the shaft within the tissue tract can be minimized by laterally deflecting the needles as they leave the shaft, while tapered depressions within the foot can guide the advancing needles into engagement with the cuffs. The cuffs lockingly engage the needles and can be withdrawn proximally along the needle paths and through the tissue tract so as to form a loop of suture across the puncture.

  • Patent number: 5967878
    Abstract: A method and system is disclosed for lapping row edges of a substrate work piece with a flat lapping element. The substrate work piece comprises a section of wafer having parallel aligned multiple row edges to be individually lapped. The wafer has different bow characteristics imparted to different substrate work piece. The bow characteristic of the substrate work piece to be lapped is determined, load points are selected on the work piece which will counteract the bow characteristic, and a pusher with push pads located at the selected load points pushes the work piece at those load points so that the pushing flexes the substrate work piece to counteract the bow characteristic to lap the row edge.

  • Patent number: 5911850
    Abstract: A method and tool are disclosed for separating a diced magnetic disk file slider from a tape to be removed by a picker. The diced slider is adhesively mounted on a wafer tape, at its attachment surface, with the air bearing surface away from the tape. The tape is positioned in a first plane, and a pushing device is projected into the tape near the leading edge of the slider to push the tape and the slider into a second plane at an angle away from the first plane. The pushing device is moved along the tape toward the trailing edge of the slider to cause the taut tape to peel from the mounted slider. A vacuum picker adjacent the tape engages the slider at the air bearing surface and removes the slider from the tape as the tape is peeled from the slider. A row of sliders may be separated by a corresponding row of pushers.

  • Patent number: 5896729
    Abstract: A container for shipping and handling devices is described. The container is particularly well suited to store sliders used in magnetic storage systems. The container includes a bottom piece and a detachable top piece. The bottom piece includes a base with a channel (also referred to as a device chamber) and two side walls. At least one device is stored in a channel in the base. The detachable top piece is secured to the bottom piece with a locking device. The locking device may include two substantially straight edges and two curved outer ridges. When the top piece is attached to the bottom piece, each of the curved outer ridges of the locking device extends into a groove in the inner surface of the side walls. The devices are contained within the container by a pair of slider stop devices.
