ARTIFICIAL CARDIAC VALVE CUSP AND METHODS OF ITS PRODUCING Russian patent published in 2008 - IPC A61F2/24 C08L77/00 C08J5/10 B29C39/00 

FIELD: medicine.

SUBSTANCE: invention relates medical technique and can be used while producing of artificial cardiac valves with one or more cusps from polymer composite. Producing method of artificial cardiac valves cusp consists in form manufacturing for cusp molding. Then the molding of cusp is made of the polymer composite containing 78-92 mas.% polyamid and 8-22 mas.% opaque medium, dispersed in polyamid. As preferential opaque medium barium sulphate is used. Polymer material can contain fine acetylene black in quantity of 1-2 mas.%. In one of the method realisation variants molding form is made according to molding sizes 1-5% less than necessary and cusp after the molding is placed in anticoagulating agent solution till swelling on 1-5%. Invention allows simplifying and decreasing the cost on the cusp producing method, improving hemocompatibility and construction reliability of artificial cardiac valve in more burden areas.

EFFECT: improvement of reliability of artificial cardiac valve with simplifying and cost decreasing of producing method.
