Patent CA-2514332-A1 (CA)
Title: Tissue pathogen inactivation/removal process
Inventor: SHIMP LAWRENCE A
IPC: A61L2/00
Filed: 2004-01-28
Abstract: Bone such as cortical or cancellous bone or connective tissue are centrifuged as a solution is applied to the tissue in a continuous process. The centrifuge creates forces, which cause the flowing solution to penetrate substantially all of the cavities of the tissue. The solution, which may be alcohol, a detergent, an oxidizer, or a surfactant, with or without water, flushes the cavities of the tissue and removes and inactivates viral and bacterial contaminants. In a second embodiment, bone or connective tissue is centrifuged in a batch process to remove contaminants from cavities in the tissue by first spinning the tissue dry and then submerging the tissue in a viral/bacteria cleansing solution and centrifuging the submerged tissue and solution at a sufficiently high speed and radius from the spin axis to create substantially high G forces on the tissue and solution to force the solution into and through the tissue cavities. The solution with the flushed contaminants is then removed from the vicinity of the tissue. In a further embodiment, an enzyme is centrifuged with the tissue to digest lipids and proteins which are then removed with a flushing solution which may also inactivate viral and bacterial contaminants. In yet a further embodiment, the centrifuge can be used to infuse biologically and/or structurally useful materials into the tissue. Further, the lipids and proteins may be removed by a chemically active agent such as oxo anions.

Title: Dispersing agent for sustained-release preparation
Inventor: HORI MASUHISA
IPC: A61P43/00
Filed: 2004-02-18
Abstract: It is intended to provide a bilayer dispersant for sustained release preparations which contains a water-insoluble solvent and a water-soluble solvent, and a sustained release preparation wherein microcapsules containing a physiologically active substance are dispersed by using the above dispersant. When this preparation is subcutaneously administered, the early release of the physiologically active substance immediately after the administration is remarkably suppressed and thus the physiologically active substance is released at a constant rate over a long period of time from immediately after the administration. Moreover, the preparation is excellent in the dispersion properties and needle penetration properties as an injection.

Title: Pocket pager protector
Inventor: LEFEBVRE MARC
IPC: H05K5/00
Filed: 2005-08-29
Abstract: A shock and water resistant wireless pager enclosure comprises a bottom having thickened walls, a top lip and interior foam strips. The top edges of the strips are coplanar with the top. A transparent film is supported thereon and on the lip and secured by a cover removably hinged to the bottom by a protrusion at one end, through which a hinge pin passes. The protrusion and pin are accepted in a trough in the bottom. The bottom is rounded about the trough to facilitate the hinged motion. The pin prevents the cover from sliding laterally from the bottom. The bottom secures the pager, the cover is fixed thereto by screws, pinching the film between them. A cover loop proximate the protrusion facilitates opening of the cover and provides a mechanism for attaching a clip. The cover may be multi-coloured for easy identification. The bottom contains a ribbon strip to facilitate pager removal and/or an RFID device to locate the enclosure and thus the pager and/or the user.
