  • Publication number: 20220071759
    Abstract: Methods, apparatuses and systems are described for delivering a stent through an access hole of a body lumen and covering up the access hole after deploying the stent. Stents are described that include a stent body defining a body lumen contact surface area and a deployable member configured to deploy from the stent body and increase the body lumen contact surface area of the stent. Deployable members that hinge, unroll, extend, expand, and coaxially translate with respect to the stent body are described. A system for delivering a stent into a body lumen are described that may include a coverage member configured to at least partially cover the hole in the wall of the stent upon withdrawing a tubular member through the hole in the wall of the stent. Coverage members may include a self-sealing membrane, a flap valve, or a hinged valve.

  • Patent number: 5723225
    Abstract: Four sheet SPF/DB panels having thick perpendicular webs formed between face sheets for areas of high compressive stress while other areas have relatively thinner webs so that the overall weight of the panel is not excessive. The thick webs are constructed by welding doubler strips or grids to core sheets when the core sheets are welded together into a core assembly prior to panel formation. When the core assembly so formed is superplastically deformed, the outer edges of the doubler strips bond to the face sheet and then are stretched into the centers of the thick webs, thereby thickening them for additional compressive strength. Normally such are used to reinforce edge joints between panels or supporting structure.

  • Patent number: 5316293
    Abstract: A toy ball, preferably a football, that emits light and bomb-emulating sounds when spiraled. It comprises a foam body defining a central bore with open ends, conical end caps associated with the ends, and an electronic circuit responsive to a centrifugal switch. The circuit and its battery are fitted within a tubular canister, preferably coaxially disposed in the bore. Rubber tethers suspend the canister between the end caps. A D-ring bracket flexibly connects one end of each tether to the canister. An S-hook connects the other tether end to an end cap. When the ball spirals during flight, a sound simulating a bomb dropped from an aircraft is emitted from piezoceramic transducers mounted on the lids of the canister. Sound horns extend from the transducers to the end caps to conduct the sound. Radially spaced apart light emitting diodes mounted in recesses in the outer surface of the ball are activated by the circuit.
