Abstract

Un guide de microtube possède un microtube combiné à un noyau libre et flottant librement.Le tube de guidage est globalement creux et pourvu d'un axe principal et d'un anneau distal. L'axe principal et l'anneau distal sont constitués de plastique souple. L'anneau distal peut s'aligner au noyau et se redresser pour être inséré dans le corps d'un patient. Il se déploi lorsque le noyau est retiré pour former une boucle. Un fil-guide est reçu par le tube de guidage. Il avance dans l'anneau distal afin d'amener le diamètre de l'anneau distal à se dilater, se rétracter ou se redresser complètement. Le diamètre de l'anneau distal est ainsi réglable par l'utilisateur.
