Abstract: A migration barrier includes a first barrier wall and a second barrier wall wherein at least one of the first and second barrier walls together provide a stable base structure that maintains the barrier assembly in an upright, standing position.

Abstract: A storage accessory is configured for selective attachment to a wall support member. The storage accessory includes a hanging tab and a locking tab. The locking tab is movable between an unlocked position and a locked position. In the unlocked position, the locking tab is configured not to penetrate a groove in a wall support member and thus to allow removal of the hanging tab from a wall support member. In the locked position, the locking tab is configured to penetrate a groove in a wall support member and thus to prevent removal of the hanging tab from a wall support member.

Abstract: The present invention relates to a support bracket for a hanger bar. The support bracket has a body having an aperture that receives an upper portion of a support hook. The body also has at least two protrusions that secure the support hook to the body.

Abstract: An anchor for securing a shelf having one or more wires to a wall is provided. The anchor has an elongate body and a head. The head has first and second grooves for receiving a wire of the shelf, wherein the first groove has an opening for receiving the wire in a direction substantially transverse to the longitudinal axis of the body and the second groove has an opening for receiving a wire of the shelf in a direction substantially parallel to the longitudinal axis of the body.

Abstract: A wire shelf having a hanger rod which permits uninterrupted hanger travel along its length, said shelf comprising. The hanger rod is secured to either the front support rod or an intermediate support rod by a plurality of support hooks. Each support hook has an end secured to the support rod, and another end secured to the hanger rod.

Abstract: An anchor for securing wire shelving and the like to a wall is provided, the anchor comprises:a spool-like head comprising a front portion, a rear portion, and an intermediate semi-circular arcuate groove extending about the entire circumference of the head, such that a portion of the wire shelving may be secured in the groove, and a means for securing the head to a wall structure.A shelving system employing this anchor is also provided, as well as a support plate/fastener combination for use in this shelving system. The support plate employs a semi-circular aperture which provides additional securing of the fastener.

Abstract: A shunt system for implantation in the body which can be used for transferring cerebrospinal fluid is disclosed. The shunt system comprises a body having an upper and lower surface and a distal and proximal end. The body includes a central cavity opening through the upper surface at a first and second port. A proximal fluid flow channel extends through the proximal end of the body and opens at a third port on the upper surface. A distal fluid flow channel extends through the distal end of the body and opens at a fourth port on the upper surface. A resilient dome comprised of a self-sealing material is attached to and extends over the upper surface of the body. A first portion of the resilient dome extends over the first and third ports on the upper surface defining a first chamber. The first portion of the resilient dome cooperates upon flexing with the third port to occlude the third port.

Abstract: Apparatus for securing a steel rod shelf to a vertical wall including a back clip anchor for lockingly engaging the rear support rod of the shelf and being mountable to the wall by means of an expandable anchor, a support brace for lockingly engaging and supporting the front support rods of the shelf, an end bracket for supporting an end of the shelf including a pair of spaced expandable anchors mountable to the vertical wall, and an expandable anchor for mounting the support brace to the wall. The back clip anchors and expandable anchors are fabricated from nylon or other flexible plastic material. The shelf apparatus is specifically designed to insure rapid and reliable installation particularly on walls constructed of dry wall or the like.

Abstract: An optical section of an intraocular lens has a pair of spaced apart threaded recesses which are threadingly locked to threaded shank sections of an iris retention loop. The shank sections are integrally joined to such loop so each shank section acts as an anchor preventing a screwing movement of the other shank relative to the optical section. A method is described of expanding a shank section of a lens retention member in situ within a threaded or other undercut recess of an optical section of an intraocular lens.

Abstract: An intraocular lens with an iris retention loop that is attached to an optical section of the lens by a pair of shank sections. Each shank section has a noncircular cross sectional area to provide a more flattened contact surface for engaging an inner edge of the iris. Such structure reduces cutting of the iris when the iris is stretched over these shank sections to retain the lens in the eye.

Abstract: An expansion device for temporary implantation beneath the skin and subcutaneous layer, there to be enlarged whereby to increase the surface area of tissue which overlays it, to provide a flap for use in plastic and reconstructive surgery. The device comprises an envelope with a substantially non-extensible base and a cover. Together the base and cover form an envelope. The cover is flexible, and when empty it is slack. The volume of the envelope is adjustably variable as a function of the amount of fluid it contains. Means is provided for admitting fluid to the envelope without puncturing the base or the cover.

Abstract: A compression implant to resist the flow of urine through the urethra comprising a cap, an external planar pressure face on the cap, a base, an external bearing face on the base, and a peripheral wall continuously interconnecting the cap and the base. A peripheral fold in the peripheral wall enables the face to move toward and away from the base by changing the shape of the fold without elastic stretching of the material which forms the wall. The cap, base and peripheral wall together define an internal cavity which can be filled with an adjustably variable amount of fluid whereby to adjust the firmness of the capsule and thereby to adjust the force which it exerts against the urethra after implantation.
