CA 2715298

The present invention provides a porous structure that works very effectively to seal a puncture site with optimum porosity, absorbent capacity and perfect anatomical fit. The plug density and other fiber properties/geometry (total denier; number of filaments; etc) have provided an efficient structure that allows instantaneous absorption of blood during deployment. The final size of the plug with absorbed fluids provides an anatomical fit and seals the puncture site within few minutes after deployment.

La présente invention concerne une structure poreuse qui permet de fermer efficacement un site de perforation et qui se distingue par sa porosité optimale, son aptitude à l'absorption, et sa parfaite compatibilité anatomique. La densité du bouchon, et la géométrie des fibres ainsi que leurs autres propriétés (titre total en deniers, nombre de filaments, etc.), confèrent au bouchon une structure efficace permettant une absorption instantanée du sang pendant le déploiement. Les dimensions finales du bouchon après absorption des fluides lui confèrent une conformation anatomique appropriée et permettent l'occlusion du site de perforation dans les quelques minutes qui suivent le déploiement.
