Title: Needle shield assembly having a single-use lock
Inventor: NEWMAN ALBERT
IPC: A61M5/32
Filed: 1997-05-27
Abstract: A needle shield assembly having a single-use lock includes a needle cannula having a proximal end connected to a hub. A collar is connected to the hub and an elongate rigid needle cover removably engages the hub and covers the needle cannula. An elongate needle shield is hingedly connected to the collar. The needle shield has two side walls defining a longitudinal opening. The needle shield is capable of pivoting from an open position where the needle cannula is exposed, to a closed needle protecting position where the needle cannula is within the longitudinal opening of the needle shield. Structure is provided for preventing the needle shield from being pivoted into the closed needle protecting position until the needle cover is removed. Structure is also provided for automatically locking the needle shield in the closed needle protecting position when the needle shield is pivoted into the closed position.

Abstract: L'invention concerne un procédé qui permet d'améliorer les critères de taxation dans un réseau téléphonique mobile, et qui consiste à choisir une cellule ou un groupe de cellules du réseau téléphonique mobile comme groupe de cellules spéciales. Les cellules du groupe peuvent se trouver dans les zones relevant de plusieurs centres de commutation mobiles. Lorsqu'une communication est établie, un point de contrôle du service (SCP) situé dans un réseau intelligent détermine si la cellule d'emplacement d'un abonné appelant et la cellule d'emplacement d'un abonné appelé appartiennent au groupe des cellules spéciales. On peut également tenir compte des numéros d'abonné. Le point de contrôle du service (SCP) applique ensuite un critère de taxation spécialement déterminé pour le groupe. Lorsque la position de la cellule de l'abonné appelant et la position de la cellule de l'abonné appelé se trouve dans différentes zones de centre de commutation mobile (MSC1/SSP1, MSC2/SSP2), l'information relative à la cellule de l'abonné appelé est transmise au point de contrôle du service (SCP1) relié au centre de commutation mobile (MSC1/SSP1) de l'abonné appelant, soit directement soit par un message conforme à la signalisation utilisée entre les centres de commutation mobile.

Patent CA-2210096-A1 (CA)
Inventor: NEWTON WILLIAM P
IPC: E05F1/16
Filed: 1997-07-09
Abstract: A coupling between a twisted rod and a torsion spring of a spiral counterbalance is found to be subject to deformation against the twisted rod from compressive force of the grip of the terminal convolutions of the torsion spring. This problem is solved by using a metal cylinder in the rotation transmission sleeve of the coupling to resist the compressive force and prevent deformation so that the twisted rod can move freely within the coupling. This solution also allows the use of a stronger torsion spring to exert a larger counterbalance force.

Title: Method for the manufacture of minimal volume capsules containing biological material
Inventor: LAMBERTI FRANCIS
IPC: A61K35/39
Filed: 1996-04-24
Abstract: The present invention provides methods and a device for producing minimal volume capsules containing viable cells or cellular aggregates. The methods and device use a two-phase aqueous emulsion system to form a dispersion of liquid capsule-forming materials in a continuous liquid phase to which is added a suspension of biological material. Alternatively, the biological material can be added to one or the other of the liquid phases. The composition of this emulsion is adjusted to promote the thermodynamically-driven process for particle engulfment by the dispersed droplets of liquid capsule-forming materials. Subsequently, the droplets engulf the biological material to form a liquid film surrounding the tissue and are converted to solid form, resulting in encapsulation of the biological material in minimum volume capsules.

Title: Method and apparatus for temporarily immobilizing a local area of tissue
Inventor: GRUNDEMAN PAUL F
IPC: A61B19/00
Filed: 1996-09-19
Abstract: A method and apparatus for temporarily immobilizing a local area of tissue. In particular, the present invention provides a method and apparatus for temporarily immobilizing a local area of heart tissue to thereby permit surgery on a coronary vessel in that area without significant deterioration of the pumping function of the beating heart. The local area of heart tissue is immobilized to a degree sufficient to permit minimally invasive or micro-surgery on that area of the heart. The present invention features a suction device to accomplish the immobilization. The suction device is coupled to a source of negative pressure. The suction device has a series of suction ports on one surface. Suction through the device causes suction to be maintained at the ports.  The device further is shaped to conform to the surface of the heart. Thus, when the device is placed on the surface of the heart and suction is created, the suction through the ports engages the surface of the heart. The suction device is further fixed or immobilized to a stationary object, such as an operating table or a sternal or rib retractor. Thus, the local area of the heart near the suction device is temporarily fixed or immobilized relative to the stationary object while suction is maintained. In such a fashion, the coronary artery may be immobilized even though the heart itself is still beating so that a bypass graft may be performed. In addition the suction device may be used in either a conventional, open-chest environment or in a minimally-invasive environment, e.g. endoscopic.
