Patent

CA 2451255

The invention includes a medical hydrogel made from polymerized polysaccharide macromers. The macromers are preferably polysaccharides decorated with polymerizable groups, for example, methacrylates. The macromers may also be made into polymers of at least two macromers polymerized together. These polymers are preferably multi-armed or high-molecular weight and used for medical uses, for example, making coatings on medical devices. Macromers of N- vinylpyrrolidone are also disclosed herein.

L'invention a trait à un hydrogel médical obtenu à partir de macromères polysaccharidiques polymérisés. Les macromères sont de préférence des polysaccharides assortis de groupes polymérisables, par exemple, des méthacrylates. Les macromères peuvent aussi être transformés en polymères d'au moins deux macromères polymérisés ensemble. Ces polymères ont de préférence une masse moléculaire multibras ou élevée et ils sont utilisés à des fins médicales, par exemple, pour former des revêtements sur des dispositifs médicaux. L'invention concerne également des macromères de N-vinylpyrrolidone.
