Abstract

DISPOSITIVO MéDICO BIOATIVO COMPREENDENDO UM STENT RECOBERTO. Dispositivo médico bioativo compreendendo um stent recoberto por uma celulose bacteriana (1) incorporando elementos para captura e aderência acelerada de células endoteliais progenitoras (4), sendo á dita superficie acoplada pelo menos uma camada de um covalente biolígante (3) que se integra especificamente a receptores de células endoteliais progenítoras CEPs (4) presentes na circulação sangúínea. Dita celulose bacteriana (1) tem a forma de uma película cilíndrica, sendo um polissacarideo sintetizado pela bactéria Acetobacter xylinum.BIOACTIVE MEDICAL DEVICE UNDERSTANDING A COVERED STENT. A bioactive medical device comprising a bacterial cellulose-covered stent (1) incorporating elements for accelerated capture and adherence of progenitor endothelial cells (4), said surface being coupled with at least one layer of a covalent bioligant (3) that specifically integrates the progenitor endothelial cell receptors CEPs (4) present in the bloodstream. Said bacterial cellulose (1) has the form of a cylindrical film, being a polysaccharide synthesized by the bacterium Acetobacter xylinum.
