Abstract: A freeze drying vessel having a drying chamber and moveable transfer belts each moved by a driven drum. Each transfer belt includes a transfer surface that transports frozen particles. Each transfer surface is arranged vertically in the chamber and moves in an opposite direction than a lower transfer surface. A removal device is located adjacent each driven drum that removes frozen particles from an end of each transfer surface, respectively, to enable removed frozen particles to flow downward to a lower transfer surface. A heating element is located adjacent each transfer belt to sublimate the frozen particles to form freeze dried product.

Abstract: The device of the present invention comprises a bifurcated graft fabricated from expanded PTFE (ePTFE). The inventive device is double walled so that following insertion into an aneurysm, fluid can be injected between the walls to expand the device thereby opening the inner tubular graft for receiving blood flow and locking the device into place in the aorta. The injected fluid may polymerize so that the device is permanently held in its expanded form. One embodiment of the device is fabricated with pockets or channels. After the device is delivered and expanded additional stiffening struts can be inserted into these pockets. In this way the basic device can be furled and tightly compressed for delivery (something not possible with a stent containing device). After the device is expanded, a stent-like structure can be inserted endovascularly giving the strength and resiliency of a stent-containing prosthesis.

Abstract: A wedge security device to be positioned on a floor at the inside bottom edge of an inwardly opening door includes a wedge shape member including an upper and lower surface leading at a front acute angle such that the bottom edge of the door will ride up on the upper surface of the wedge with a rounded surface extension allowing the wedge to rock backwardly when the edge of the door engages the wedge, a resilient compressible pad to facilitate wedging of the member under the door and a rubber appendages pad on the bottom of the wedge shape to prevent sliding along the floor surface with a pair of guide member with slots to allow the door to move toward and up on the wedge shape, but prevent its movement backwardly away from engagement once it has been wedged into position.
