Title: Surgical clip
Inventor: BEARDSLEY JOHN W
IPC: A61B17/128
Filed: 1997-08-26
Abstract: A surgical clip with advantageous closure characteristics is disclosed which includes a bail portion having first and second back portions joined at an apex, and rectilinear leg portions extending from the back portions. The apex is preferably characterized by an angle of no more than about 100°. Preferably the outer surface of at least one back portion includes a compression ridge to concentrate the compression force applied by the jaws of the applying instrument to a preselected region of the clip.

Patent CA-2218458-A1 (CA)
Inventor: BERSHTEVN MIKHAIL
IPC: G06F17/50
Filed: 1997-10-16
Abstract: A method and apparatus for combining emulation and simulation of a logic design. The method and apparatus can be used with a logic design that includes gate-level descriptions, behavioral representations, structural representations, or a combination thereof. The emulation and simulation portions are combined in a manner that minimizes the time for transferring data between the two portions. Simulation is performed by one or more microprocessors while emulation is performed in reconfigurable hardware such as field programmable gate arrays. When multiple microprocessors are employed, independent portions of the logic design are selected to be executed on the multiple synchronized microprocessors. Reconfigurable hardware also performs event detecting and scheduling operations to aid the simulation, and to reduce processing time.
Patent CA-2220377-A1 (CA)
Inventor: YU CHENG DER TONY
IPC: A61K9/70
Filed: 1997-11-06
Abstract: The invention provides methods and means for enhancing the epidermal, transdermal and dermal permeation of a topically applied pharmacologically active agent (e.g., a drug or medicament) which has a low rateof skin penetration in the absence of a permeation enhancer and which is unstable and degrades during long-term storage with particular permeation enhancers. Alsoprovided by the invention are methods and means to increase the skin penetrationof a pharmacologically active agent which has a normally low rate of skin permeation and causes the instability and degradation of a permeation enhancer with which it is combined over a long period of time. Provided by the invention are at least one first composition containing a drug, a pharmaceutically acceptable salt, chemical derivative, or formulation thereof, in a dermatologically acceptable vehicle, and at least one second composition containing a permeation enhancer inan acceptable vehicle. The compositions are physically separated until application to a body or skin surface and are topically applied, either at the same time, orsequentially within a short time of each other, and mixed or blended to form a final active composition, preferably on the skin. In addition, a premixture of the compositions can be made and applied to the skin in accordance with the invention. The invention allows a therapeutically effective amount of drug to be delivered into the skin and systemic circulation and provides significant enhancement of a drug's otherwise low level of skin permeation by the action of permeation enhancer in the active composition at the point of use.

Title: Recombinant bacterial system with environmentally limited viability
Inventor: TINGE STEVEN A
IPC: A61K35/76
Filed: 1996-06-07
Abstract: Disclosed in an Environmentally Limited Viability System (ELVS) for microorganisms based on differences between permissive and non-permissive environments. Viability of the microorganisms are limited to a permissive environment by specifically expressing one or more essential genes only in the permissive environment, and/or expressing one or more lethal genes only in the non-permissive environment. Temporary viability in a non-permissive environment can be achieved by temporarily expressing one or more essential genes in a non-permissive environment, and/or temporarily delaying expression of one or more lethal genes in the non-permissive environment. Environmentally Limited Viabilty Systems are also disclosed involving coordinate expression of a combination of required genes and lethal genes. Microorganisms containing an Environmentally Limited Viability System are useful for release into permissive and non-permissive environments. Temperature regulated Environmentally Limited Viability Systems are particularly suited for delivery of expression products, such as antigens, using recombinant avirulent Salmonella by limiting their growth to the warmer environment inside the host, or by allowing growth for only a limited time in the host.
