Covalon Receives Patents in France, Germany and UK for Drug Delivery via Therapeutic Hydrogels.MISSISSAUGA, Ontario -- Covalon Technologies Ltd. ("Covalon") (TSX TSX Toronto Stock Exchange (TSE before April, 2002) TSX Transfer from Stack Pointer to Index TSX True Space Extension VENTURE:COV COV Composés Organiques Volatiles (French) COV Compuestos Orgánicos Volátiles (Spanish: Volatile Organic Compounds) COV Coefficient of Variation COV City of Villians (game) ) has received notice that patents have issued in France, Germany and the United Kingdom for its technology entitled: "Drug delivery via therapeutic hydrogels". The technology can be used as a drug delivery platform involving the retention of a drug within liposomes Liposomes Aqueous compartments enclosed by lipid bilayer membranes; liposomes are also known as lipid vesicles. Phospholipid molecules consist of an elongated nonpolar (hydrophobic) structure with a polar (hydrophilic) structure at one end. which are microscopic spheres of lipid designed to act as time-release drug depots. The medical devices that may benefit form the technology include wound dressings, implantable medical devices and wound closure systems useful for helping to reduce hospital acquired infection. The type of therapeutic agent that can be encapsulated within the liposomes is not restricted to a single type of antiseptic or combination of one or more of these. The hydrogel hy·dro·gel n. A colloidal gel in which the particles are dispersed in water. hydrogel a gel that contains water. hydrogel Wound care A polymer absorptive wound dressing.
