Patent CA-2212300-A1 (CA)
Title: In vitro or in vivo gelfying chitosan and therapeutic uses thereof
Inventor: COMBES CRYSTELLE
IPC: A61L26/00
Filed: 1997-08-04
Abstract: The present invention relates to composition, method and applications of loaded or unloaded Chitosan-.beta.-Glycerophosphate hydrogels are proposed for cosmetic,  medical  and  surgical  applications.  Solid .beta.-Glycerophosphate is added and dissolved at low positive temperature (10°C) within 0.5 to 3.0% w/v Chitosan in aqueous acidic solutions. The aqueous Chitosan-.beta.-Glycerophosphate solutions,  initially stored at low positive  temperatures,  preferentially  at  4°C,  are endothermally gelated within the temperature range of 30 to 60°C, preferentially at 37°C. The said Chitosan-.beta.-Glycerophosphate  solution  spontaneously  transforms into a gel at the desired gelation temperature. Gelation can be ex vivo within any receivers or molds, or in situ in animals or humans so as to fill a tissue defect or cavity.  Encapsulation of  living  cells  or cellular matters is carried out by incorporating the said cells or cellular matters within the aqueous Chitosan-.beta.-Glycerophosphate  solution  at  a  low positive temperature  (ideally at  4°C),  then by  gelating  the cells  loaded Chitosan-.beta.-Glycerophosphate  solution at the selected gelation temperature  (ideally at 37°C). Chitosan-.beta.-Glycerophosphate hydrogels without encapsulated living cells are selected for surgical reconstructive and regeneration uses and drug delivery purposes.  Chitosan-.beta.-Glycerophosphate  with  encapsulated living cells are applied to the culture and engineering of artificial tissues as well as to the reconstruction of tissues. Engineering and regeneration of articular cartilage and cartilageous tissues are targeted through the injection and in situ gelation or the implantation of chondrogenic cells loaded in Chitosan-.beta.-Glycerophosphate systems.

Title: Decentered noncorrective lens for eyewear
Inventor: HOUSTON MALCOLM NEAL
IPC: A61F9/02
Filed: 1996-12-04
Abstract: Disclosed is an optically corrected lens for nonprescription eyeglasses. In a preferred embodiment, the anterior surface of the lens lies on a portion of a first sphere having a first center. The posterior surface of the lens lies on the surface of a second sphere having a second center. The first and second centers are offset from one another to provide a tapered lens. The lens is oriented on the head of the wearer by a frame that maintains the lens in a position such that a line drawn through the first and second centers is maintained substantially in parallel to the normal sight line of the wearer. Lenses are thus provided which have improved optics when mounted in an as-worn orientation such that they exhibit both vertical "rake" and horizontal "wrap".  Methods of making the lenses, and eyewear incorporating the lenses, are also disclosed.

Title: Vena cava delivery system
Inventor: CATHCART BRUCE C
IPC: A61B17/22
Filed: 1996-05-23
Abstract: A delivery system (10) for delivery and deployment of devices (23) having abrading portions (24) within a patient's lumen. A lumen in a flexible catheter (13) that extends proximally from a distal end (15) of the catheter receives the device in a compact form. At least one impervious segment (20) positioned in the lumen overlies the abrading portions of the device to shield and buffer the catheter from the abrading portions. The segment is of a relatively short length so that the catheter remains relatively flexible therealong to ease the transit of the catheter through the patient's lumen to a delivery site. Additional segments (50, 51, 52) may be disposed in the catheter distally of the segment or the segment may move with the device to the distal end to buffer the catheter during deployment of the device.  Additional segments mate with the segment so that engaged segments are relatively radially deflectable.

The method and apparatus can include a conveyor (28) configured to provide the moving substrate (26) at a selected substrate speed, and a transporter (30) configured to deliver a component web (24) at a selected component web speed which differs from the substrate speed. A rotatable applicator roll (32) has an appointed rotational direction (36), and an outside applicator surface (34). The applicator roll is configured to be rotated at a rate which provides to the applicator surface (34) a surface speed which is substantially equal to the substrate speed. At least one deceleration carriage (40) is assembled to rotate with the applicator roll (32) and is configured to receive and hold a selected portion of the component web (24). Thedeceleration carriage is configured to translate along a carriage movement path (42) from an appointed first position (44) to an appointed second position (46) while moving substantially opposite to the rotation direction (36), and is configured to be repositionable along a carriage return path (50) to the first position (44). A divider, such as rotary cutter (52), coordinates with the applicator roll (32) to intermittently separate the component web (24) into individual component web segments (22), which can then be assembled to the moving substrate (26).

Patent CA-2226737-A1 (CA)
Title: A device for joining members
Inventor: LANGEGGER JOSEF
IPC: F16B5/00
Filed: 1996-05-31
Abstract: The invention concerns a device for connecting, for example, two wooden parts which are to be bonded together and have mutually abutting flat surfaces. The device comprises two sections (31, 32), each of which is provided with barblike projections (35). The two sections (31, 32) are movably guided in the axial direction (36) and mutually spring-loaded. The sections are held at a spacing by a spacer which is destroyed as a result of an impact being applied to one of the wooden parts to be connected. The two sections (31, 32) are consequently moved towards each other owing to the spring-loading and the two wooden parts are urged against each other such that they are held rigidly.

Patent CA-2241895-A1 (CA)
Title: Restoration systems for an optical telecommunications network
Inventor: LIU SHOA-KAI
IPC: H04Q3/00
Filed: 1996-12-27
Abstract: An optical telecommunication network has a plurality of optical cross-connect switching nodes linked together by optical cables to form transmission paths for traffic between sending and destination stations. A centralized operation support system (OSS) is coupled to each node for receiving failure alarms and port status messages for failed cables from the switching nodes and terminal sites. The collected data is used to select alternate routes through the network using the spare capacity of the optical cross-connect switches and available wavelengths within the network. Any connection(s) to put into effect an alternate routing plan is broadcast to the affected nodes or terminal sites. A Real-Time Multiple Wavelength Routing (RMWR) algorithm is used by the OSS or by decentralized switching nodes to select, coordinate and route traffic among selected paths to bypass the failed cable such that wavelength collisions or adjacent cross-talk do not degrade the network performance. The OSS is uptated when network restoration is performed by a switching node in the path of the failed cable.
