Patent CA-2386294-A1 (CA)
Inventor: DEWEY CHARLES H
IPC: E21B23/01
Filed: 2002-05-14
Abstract: A method and apparatus to affix a tool downhole in a cased wellbore, one embodiment comprising a tubular body with a slot along its length. A portion of the slot is V-shaped to accommodate a wedge with a corresponding V-shape. The outside of the tubular body has integral teeth. To set the apparatus, the wedge is driven into the V-shaped slot. This movement widens the slot and expands the diameter of the tubular body until it intersects with the casing. The teeth on the outside of the body bite into the casing wall to affix the tool to the casing.

Abstract: The present invention is a stent that is designed to have optimal strength a nd radio-opacity with good biocompatibility. To achieve optimal radio-opacity, the stent design of the present invention is adjusted to the specific radio- opacity and strength characteristics of the metal from which the stent is fabricated. What is more, coatings such as parylene may be needed to avoid corrosion from stents with less biocompatible materials and/or dissimilar metal on the stent's outer surface. The achievement of optimal radio-opacity  occurs in a stent that ideally is only 0.004 inches wall thickness or less. Such a stent would have a pre-deployment outer diameter (profile) that would  be at least 0.003 inches less than currently marketed stents. Ideally, the sten described herein would have a wall thickness between 0.0025 inches and 0.004 inches.

Abstract: This invention relates to an improved method for the production of a pour-in - place composite article. These composite articles composite an exterior covering (2) and a flexible polyurethane foam core. This method comprises inserting a support armature (4) into a pre-sewn exterior covering (2), positioning an exterior covering in a shaped mold (1), and applying pressurized gas to the outside surface of the exterior covering at the point  directly opposite the position that the reaction mixture will be injected in to the mold through air inlet (10). The pressurized gas is either applied to th e outside surface of the exterior covering either at some point prior to injection of the reaction mixture into the shaped mold, or the pressurized g as is applied simultaneously with the injection of the reaction mixture into th e shaped mold. The application of pressurized gas is discontinued once the injection step is completed, allowing the reaction mixture to fully react an d expand to conform the composite article to the shape of the mold.

Abstract: An interface arrangement is disclosed for ensuring proper dosing as well as achieving a safe operation and handling of a dry powder inhaler (DPI) used f or administration of a powder to be inhaled. The interface of the present invention primarily handles the loading of a cassette (4) carrying pre-meter ed doses into the dry powder inhaler (8). An important characteristic is that t he interface by utilizing a particular coding prevents a user from loading a cassette not containing the proper powder. Additionally the interface inform s a user when a new mouthpiece has to be replaced after being used for a pre- defined number of inhalation operations. Additionally the interface informs a user when a present cassette has delivered its last dose and should be exchanged. Also information on the number of further cassettes already utilized will control that another cassette still is permitted to be loaded.  If this counter exceeds a pre-defined number of used cassettes the inhaler then is be definition worn out, whereby the present dry powder inhaler has t o be scrapped. In that case the last cassette will not be able to be released from the inhaler device but will accompany the inhaler when it is discarded.
