  • Publication number: 20090035350
    Abstract: The present invention is directed to polymeric compositions comprising a biodegradable copolymer that possesses shape-memory properties and implantable devices (e.g., drug-delivery stents) formed of materials (e.g., a coating) containing such compositions. The polymeric compositions can also contain at least one non-fouling moiety, at least additional biocompatible polymer, at least one biobeneficial material, at least one bioactive agent, or a combination thereof. The polymeric compositions are formulated to possess good mechanical, physical and biological properties. Moreover, implantable devices formed of materials comprising such compositions can be delivered to the treatment site in a conveniently compressed size and then can expand to dimensions appropriate for their medical functions.

  • Publication number: 20080305138
    Abstract: The invention provides a method of preparing an antimicrobial sponge material for medicinal use, comprising the steps of: treating an anionic polysaccharide with a solution of a silver salt to produce a complex of the anionic polysaccharide with silver; dispersing said complex in aqueous ascorbic acid to form an acidified dispersion, followed by freeze-drying or solvent-drying the dispersion to form the sponge material. Also provided is a photostabilized antimicrobial sponge material comprising an anionic polysaccharide complexed with silver (I) ions, wherein the sponge further comprises ascorbic acid, and the sponge has a substantially white colour that is substantially stable against discoloration on exposure to light. Also provided are wound dressings comprising such materials, and the use of such materials in medicine.
