Title (EN) CATHETER FOR OPENING AN OBSTRUCTION IN A BODY VESSEL AND METHOD FOR OPENING SUCH OBSTRUCTION USING THE CATHETER
(FR) CATHÉTER POUR OUVRIR UNE OBSTRUCTION DANS UN VAISSEAU CORPOREL ET PROCÉDÉ POUR OUVRIR UNE TELLE OBSTRUCTION À L'AIDE DU CATHÉTER
Abstract:
(EN) The present invention concerns a catheter (10) for opening an obstruction in a body vessel, the catheter comprising: a distal portion (11) having a rotatable boring element (21) comprising a screw thread (21), the boring element (22) being arranged upon rotation to draw itself distally into the obstruction; and a shaft portion (26) extending between the distal portion (11) and a proximal portion (12); wherein the shaft portion (26) comprises a hand-rotatable knob system (23) such that the rotation of the knob (23) applies a rotational torque in the desired direction to the shaft portion (26), which is, in turn, transmitted to rotate the boring element (21) as desired; and wherein the screw thread (21) has a pitch (P) between 0.5 mm and 5 mm. The present invention also concerns a method for opening an obstruction in bodily vessel using the catheter.
(FR) La présente invention concerne un cathéter (10) pour ouvrir une obstruction dans un vaisseau corporel, le cathéter comprenant : une partie distale (11) ayant un élément de forage rotatif (21) comprenant un filetage de vis (21), l'élément de forage (22) étant agencé lors de la rotation pour s'étendre de manière distale dans l'obstruction ; et une partie tige (26) s'étendant entre la partie distale (11) et une partie proximale (12) ; la partie tige (26) comprenant un système de bouton tournant à la main (23) de telle sorte que la rotation du bouton (23) applique un couple de rotation dans la direction désirée à la partie tige (26), qui est, à son tour, transmis pour faire tourner l'élément de forage (21) selon les besoins ; et le filetage de vis (21) ayant un pas (P) compris entre 0,5 mm et 5 mm. La présente invention concerne également un procédé d'ouverture d'une obstruction dans un vaisseau corporel à l'aide du cathéter.
