Prevention of displacement of prosthetic devices within aneurysms

InactiveUS20080275536A1Augmenting resistance to migrationAvoid lateral displacementStentsBlood vesselsStent graftingImplanted device
Devices and methods are provided for reducing the lateral displacement of an endovascular device, e.g. a stent graft, within an aneurysm sac. A stabilization system comprising one or more stabilizing elements is inserted within the aneurysm space between an implanted device and the vessel wall. Filling this space prevents changes in curvature of the implanted endovascular device, and prevents longitudinal displacement, thereby providing for improved long-term stability and durability of endovascular repair.

System and method for sealing couplings in downhole tubing strings

For oil production systems, an interior two-part seal ring of resilient material is disposed within a coupling sleeve which receives threaded tubing ends in its opposite ends. The seal is asymmetric, with tapered ends of different lengths and taper angles. A length for mill end engagement is shorter than the length for field end engagement which may be made up and disconnected repeatedly. The seal configuration includes a principal body with a inwardly directed ridge between its tapered ends and a reinforcing ring of different, less permeable material, abutting the ridge and closing off one or more radial ports in the wall of the body. The central body also includes a circumferential gas groove about is periphery, which together with the radial ports, facilitates collection and release of gases permeating the seal body under high down-hole pressures.

Corrosion-resistant tension member, particularly a tendon for prestressed concrete

A corrosion-resistant tension member, particularly a tendon for prestressed concrete, comprising a bundle of tension elements arranged inside a sheathing, has at its ends anchoring devices each with an anchor plate. On the side of the anchor plate facing away from the open air side, a seal having tension elements running through it and having a sealing plate are arranged, the sealing plate being fixed in place on the side facing away from the anchor plate opposite the anchor body against longitudinal displacement. Between the anchor plate and a pressure plate butting against the sealing plate, pressure-transferring means, for example, a pressure tube, are provided, having a length calculated in such a way that a longitudinal displacement of the anchor plate that occurs when the tension elements are being tensioned, actuates the exertion of surface pressure to the sealing plate for activating the seal.

Shin Guard Compression Sleeve

Tools and techniques for providing protection to a foot and leg with a shin guard compression sleeve underlying a shin guard are presented. A shin guard compression sleeve may comprise a toe shoe having individual toe apertures and pockets intended to contain the toes of a foot received therein, and, an elastic tubular liner operatively associated with the toe shoe. The elastic tubular liner may compressively receive a portion of a leg and have a length sufficient to extend beyond the top of a shin guard receiving the sleeve, such that the tubular liner defines a first layer under the shin guard, and a second layer overlapping the first layer when folded over. The second layer may hook over an end portion of the shin guard, thereby sandwiching the shin guard between the first and second layers of the elastic tubular liner.
