Patent CA-2340417-C (CA)
Title: Methods for forming regional tissue adherent barriers and drug delivery systems
Inventor: SAWHNEY AMARPREET S
IPC: A61K31/78
Filed: 1999-08-13
Granted: 2008-11-18
Abstract: Methods are provided for forming hydrogel barriers in situ that adhere to tissue and prevent the formation of post-surgical adhesions or deliver drugs or other therapeutic agents to a body cavity. The hydrogels are cross-linked, resorb or degrade over a period of time, and may be formed by free radical polymerization initiated by a redox system or thermal initiation, or electrophilic-neutrophilic mechanism, wherein two components of an initiating sytem are simultaneously or sequentially poured into a body cavity to obtain widespread dispersal and coating of all or most visceral organs within that cavity prior to gelation and polymerization of the regional barrier. The hydrogel materials are selected to have a low stress at break in tension or torsion, and so as to have a close to equilibrium hydration level when formed.

Abstract: Acrylate copolymer pressure-sensitive adhesive constructions are described which provide excellent retention of rivet properties.  Tenting around rivets is minimized even after undergoing thermal aging while in contact with additive rich films like PVC. This is achieved by the inclusion of a synergistic amount of an N-vinyl lactam monomer and acid monomer with the bulk of the monomers being an alkyl acrylate save and/or methacrylate esters. A concomitant increase in cohesive strength is also achieved which affords good removal characteristics. The use of appropriate adhesive blends is further disclosed which allows retention of these features while also improving cold temperature properties.

Abstract: The present invention provides a film-forming composition comprising a particulate polymer or emulsified liquid pre-polymer, water and a coalescent aid comprising an ester having the formula RCOOX wherein R and X are independent lyhydrocarbyl or substituted hydrocarbyl, and at least one of R and X contain at least two unsaturated carbon-carbon bonds. The coalescent aid helps lower the minimum film formation temperature of low glass transition temperature coatings and high glass transition temperature coatings and allows optimum film formation at ambient temperatures. The coalescent aid of this coating composition is not volatile like conventional coalescent aids but rather remains part of the film and air oxidizes to cure the film. This coating composition also exhibits properties of adhesion and gloss superior to that of coating compositions containing conventional coalescent aids. Additionally, this coalescent aid can be made from natural or synthetic oils.

Abstract: L'invention concerne un dispositif de filtration pour prélever un échantillon de filtrat d'un liquide contenant des particules solides. Ce dispositif de filtration comprend deux parties filtres (100, 102) et au moins une fente filtrante (108) située entre les parties filtres (100, 102). Ces parties filtres (100, 102) sont adaptées pour bouger relativement l'une à l'autre, de manière à ce que la largeur de la fente filtrante (108) change lorsque les parties filtres (100, 102) bougent relativement l'une à l'autre.
