  • Heparin-mixed menstruation through a saline infusion for scraped off debris It is possible to allow the injection of brine, easily removing thrombus debris through a structure that can absorb the physiological saline solution containing the debris are sucked through the debris on the opposite side.

Abstract

Selon un dispositif d'outil entrant dans un vaisseau sanguin bloqué par l'intermédiaire d'une vraie lumière et retirant un thrombus, proposé par la présente invention, le dispositif d'outil est amélioré par la modification d'un procédé classique de support simple d'un dispositif d'athérectomie à l'aide d'un support de ballonnet, et est ainsi configuré par couplage d'un support de ballonnet, d'un outil de perforation pour perforer une lumière et d'un dispositif d'athérectomie pour couper un thrombus, de telle sorte que le dispositif d'outil peut toujours commencer à passer à travers une partie de lésion à partir du centre d'un vaisseau sanguin et peut se poursuivre sans s'échapper de l'intérieur d'une vraie lumière.
