CUFF FOR HEART'S ARTIFICIAL VALVE AND METHOD OF MAKING THE CUFF Russian patent published in 2006 - IPC A61F2/24 A61L27/28 C23C18/44

Abstract RU 2286116 C2

FIELD: medicine; cardio surgery.

SUBSTANCE: cuff for heart's artificial valve is made of synthetic material. Tissue is impregnated with particles of restored silver. To produce cuff, synthetic material is subject to degreasing and impregnation of compound of silver solution. Then material is subject to drying and compound impregnated the material is restored till achieving metal silver. Material, covered with silver, is washed away of residuals of reagents. Then silver, that covers material, is passivated. Septic myocardium can be prevented due to improvement in antibacterial properties of cuff.

EFFECT: improved efficiency of operation; prolonged service life.
