Patent CA-2261419-A1 (CA)
Inventor: WONG HARRY YAN
IPC: A61B17/00
Filed: 1999-02-02
Abstract: The invention described herein details an embodiment of an instrument that can be used as a means to extract various types of foreign bodies that are lodged and/or become entrapped in a body orifice such as the nasal passage or the outer ear canal.   The preferred embodiment of the invention is constructed of a molded plastic in a shape of an elongated cylindrical shaft, of sufficient length and diameter to be held in a persons hand like a pencil A contact surface at one end of the shaft is modified to present a concave surface to engage the outer surface of a foreign body such as a marble, bead, or nut.  That has become lodged in a tight-fitting orifice. On or near the contact surface there is an opening that is connected to a channel running through the cylindrical shaft.  This channel is connected to a compressible bulb attached to the opposite end of the channel, and in the preferred embodiment herein, is an integral part of the handle.  This bulb is positioned on the handle in approximately the same position that the index finger would be, if the instrument were to be held like a pencil. Inside the bulb is a predetermined and sufficient volume of a liquid quick-setting adhesive material.   When the bulb is depressed a fixed volume of adhesive material is expelled from the bulb, into and along the channel, and out the opening and onto the concave surface. Once the adhesive material has been expressed from the opening, the operator of the instrument will be able to manually advance the instrument in the orifice until it contacts the entrapped foreign body. The instrument is held in place against the foreign body as the adhesive hardens, after which the foreign body, now attached too the contact surface, can be removed by grasping the instrument and applying a gentle traction of the device from the orifice.

Title: Covalent polar lipid conjugates with biologically-active compounds for use in salves
Inventor: STOWELL MICHAEL H B
IPC: A61K47/48
Filed: 1996-07-23
Abstract: This invention herein describes a method of facilitating the entry of drugs into cells and tissues at pharmokinetically useful levels and also a method of targeting drugs to specific organelles within the cell.  This polar lipid/drug conjugate targeting invention embodies an advance over other drug targeting methods because through this method, intracellular drug concentrations may reach levels which are orders of magnitude higher than those achieved otherwise. Furthermore, it refines the drug delivery process by allowing therapeutic agents to be directed to certain intracellular structures. This technology is appropriate for use with antiproliferative, antibiotic, antimycotic, antiviral and antineoplastic drugs, in particular in combination with a multiplicity of other emollients and agents to make up topically-active substances such as salves, for rapid and efficient introduction of such agents through the epidermis for treatment of skin diseases and other disorders.
Patent CA-2263978-A1 (CA)
Title: Enhanced stimulation of erythropoiesis
Inventor: MUELLER SUSAN
IPC: A61K38/18
Filed: 1997-08-27
Abstract: The present invention is directed to compositions comprising heme-containing components and to methods that stimulate erythropoiesis comprising administration of a composition of the invention, such as purified hemoglobin. Surprisingly, heme-containing components such as hemoglobin can induce erythopoiesis in the presence of decreased concentrations of erythropoietin (Epo) and, in fact, function synergistically with Epo. Further, hemecontaining components can be used alone or in conjunction with Epo for the treatment of anemias and other disorders due to decreases in erythropoietin or iron. It has been discovered that, in the presence of Epo, both hemoglobin and cross-linked hemoglobin can compensate for the reduction in erythroid cell growth and differentiation that occurs in the presence of reduced concentrations of Epo. The effect is specific to erythropoiesis, as evidenced by a lack of growth of non-erythroid progenitors such as CFU-GM.

Abstract: An optical device (300) comprises a multilayer structure, formed by wafer bonding, incorporating in sequence a silicon dioxide layer (304), a buried silicide layer (306), a contact layer (308) and a silicon surface layer (310). The surface layer (310) is selectively etched to form an exposed rib (312). An upper surface of the rib (312) is doped to form an elongate electrode (314) therealong. The surface layer (310) is selectively etched to the contact layer (308) in regions remote from the rib (312) to form via channels (316a, 316b) for making electrical connection to the contact layer (308). The rib (312) forms a waveguide along which radiation propagates. When the electrode (314) is biased relative to the contact layer (308), charge carriers are injected into the rib (312) and induce refractive index changes in a central region (324) thereof where most of the radiation propagates along the rib (312). The silicide layer (306) provides an efficient current conduction path for injecting the carriers, thereby providing enhanced device operating bandwidth and reduced power dissipation.
