Title: Bi-caval cannula
Inventor: HUYBREGTS MARINUS ADRIANUS JOS
IPC: A61F2/958
Filed: 1993-07-08
Abstract: A single cannula for draining venous blood with which both partial and total bypass of the heart can be realized. To prevent incision in the right atrium, the cannula is inserted via an incision in the wall of one of the venae cava, is lead through the entrance of the vena cava in the right atrium, through the right atrium to the entrance of the other vena cava in the right atrium, and into the not-incised vena cava. To this purpose, the cannula is so designed that both a connection with the inferior vena cava as well as the superior vena cava is provided. This is done by providing the cannula with a bend, and by positioning a side opening in this bend. To realize total bypass and to provide cooling and isolation of the heart during operations, an inflatable cooling mantle is positioned around the part of the cannula that resides in the right atrium. Furthermore, provisions are made which, during total bypass, enable realization of selective and simultaneous access to the right atrium and to the mouth of the coronary sinus in the right atrium.
Patent CA-2142595-A1 (CA)
Title: Elastic membrane
Inventor: LUCK GERALD
IPC: B61D17/22
Filed: 1994-05-24
Abstract: ELASTIC MEMBRANE                 ABSTRACT    The elastic membrane is designed as a flat, three-dimensional object.  It has prominences and depressions.          This makes possible a deformation which is substantially free of stress, in particular free of tensile stress, simultaneously in all three dimensions.  The elastic membranes of this type which are known today suffer from the disadvantage that they are not substantially free of stress, and in particular free of tensile stress, in all three dimensions and therefore cannot meet certain requirements.

Patent CA-2157661-A1 (CA)
Inventor: DENT PAUL W
IPC: H04B7/08
Filed: 1995-01-27
Abstract: On démodule un signal a liaison descendante AMDC en filtrant des corrélations du signal reçu avec une séquence de signature connue. Contrairement au récepteur Rake classique le dispositif de filtrage n'est pas nécessairement un filtre à réponse impulsionnelle finie (FIR) (102) dont les coefficients sont égaux aux conjugués des estimations (105) de mise en dérivation des canaux. Dans cette invention le filtrage s'effectue de manière à maximiser le rapport signal/bruit de sortie étant donné qu'une partie du bruit parvient de la même station de base que le signal pour qu'il soit coloré par le même canal que le signal. Pour cela on remplace le filtre combinateur FIR (102) du RAKE avec un filtre plus général tel qu'un filtre à réponse impulsionnelle infinie (IIR) (202) ou un filtre FIR (402).

Patent CA-2166284-A1 (CA)
Inventor: ROBROCK RICHARD BARKER II
IPC: H04L12/56
Filed: 1994-06-16
Abstract: A Broadband Intelligent Network employs an ATM fast-packet switch to route signaling cells from a calling party to a switch port directly connected to a Service Control Point (SCP) (61). The signaling cells carry a service request that requires the support of a network resource, and, in the specific case described herein, the support of the Line Information Data Base (LIDB) (150) to facilitate the establishment of a switched virtual connected to a called party (54). The SCP (61) acts on the information in the signaling cells and selects the required resource, i.e., the LIDB (150), and then sends a query cell(s) to the LIDB (150) through a permanent virtual connection in the ATM switch (51). The LIDB (150), in turn, acts on the information in the query cell(s) to assemble a response cell(s) with the requested information. The response cell(s) is sent to the SCP (61) through the permanent virtual connection in the ATM switch (51), thereby enabling the SCP to complete call processing, establish the requested connection, and generate a billing record (65).
Patent CA-2166428-A1 (CA)
Title: Surgical attachment device
Inventor: DOBKIN WILLIAM R
IPC: A61B46/23
Filed: 1996-01-02
Abstract: Apparatus for securing one or more suction tubes, hoses, electrical and/or endoscopic cables, and intravenous and cardiovascular bypass tubing during an operation.  The apparatus is a surgical attachment device that comprises a member (preferably molded plastic) having at least one opening adjacent a first surface thereof. A first portion of each opening is designed to slidably secure the tubes, hoses or cables.  A second portion of each opening immediately adjacent the first surface is smaller than the dimension of the first portion.  The first portion of each opening tapers from a narrow dimension at the center of the member to a wide dimension at opposite ends of the member.  Each opening has a plurality of inwardly projecting tapered ribs disposed around its internal periphery that taper from their narrowest dimension at the center of the opening to their widest dimension at the ends of each opening.  The inwardmost edges of the plurality of tapered ribs have a dimension nominally equal to or narrower than the narrowest dimension of the tapered opening.  The tapered ribs assist in securing the tubes, hoses or cables in the opening and prevent unwanted sliding thereof.  The inwardmost edges of the ribs contact the tubes, hoses or cables when they is inserted into the opening.  One pair of ribs or projections are larger than the others and are initially encountered when a hose or tube is pressed into the first portion of the opening.  This configuration secures the various hoses and tubes, and the like, within the second portion of the opening and prevents their inadvertent pull-out.  An adhesive layer is disposed on a second external surface of the member for securing it to a surgical drape during an operation.  The surgical attachment device may be flexible or deformable between the first and second portions of each opening to permit passage of nonflexible tubes, hoses or cables through the second portion of the opening.  This may be achieved by adding additional lower slots separated from selected openings by hinge areas that provide for easy flexing of the member at the openings to permit insertion of the tubes, hose, or cables therein.  The flexible portion comprises one or more living hinge areas that flex to open each of the openings.

Patent CA-2174933-A1 (CA)
Inventor: MARSHALL BARRY J
IPC: C12Q1/04
Filed: 1994-10-25
Abstract: L'invention concerne un procédé de détection in vivo d'hélicobacter producteur d'uréase au niveau de la grande tubérosité de l'estomac. L'excipient dense est divisé en deux groupes séparés qui sont combinés avec des réactifs colorés séparés, l'un de ces indicateurs contenant également de l'urée. Les excipients sont des substances solubles dans le bol alimentaire, de préférence des perles de sucre d'un diamètre allant d'approximativement 0,2 mm à 3,0 mm compris. Les excipients traités et l'urée sont encapsulés dans une capsule soluble à administrer au patient. La densité des excipients provoque la migration de la capsule vers la muqueuse gastrique où elle se dissout. Les réactifs et l'urée entrent alors en contact direct avec la muqueuse gastrique. L'urée réagit avec l'uréase éventuellement présente dans l'estomac, ce qui dégage de l'ammoniaque et donc accroît le PH à l'intérieur de l'estomac. Les deux réactifs réagissent à l'accroissement du PH de façon différente, par un changement de couleur que l'on observe au moyen d'un endoscope. Une premier réactif préféré est le bleu de bromothymol (dibromotymo/sulfone-phtaléine) qui vire au jaune en présence d'uréase, et un second réactif préféré est le rouge du phénole (phénolsulfone-phtaléine) qui vire au rouge en présence d'uréase.
