Title (EN) RE-ENTRY DEVICE FOR PERIPHERAL ARTERIAL RECANALIZATION PROCEDURES
(FR) DISPOSITIF DE RENTRÉE POUR PROCÉDURES DE RECANALISATION ARTÉRIELLE PÉRIPHÉRIQUE
Abstract:
(EN) A re-entry device (1) for recanalization procedures of an arterial vessel by an intraluminal or subintimal technique comprises a catheter (10) having a distal end (12) with a curved tip (13) by an angle (a) of between 30° and 90°, and an angled-tip stylet (2) intended to be inserted into the inner lumen of the catheter (10) to exit from a distal opening (14) thereof. The angled-tip stylet (2) is made of a metal material and has a distal end (22) with a curved tip (23) ending in a sharped apex (24). In particular, the distal end (22) of the an angled-tip stylet (2) is tapered and has a length of between 3cm and 5cm, and the curved tip (23) is bent by an angle (β) of between 30° and 50°: such a structure makes the apex (24) adjustable also outside the two- dimensional plane defined by the curved tip (13) of the catheter (10) to facilitate the penetration of the arterial wall.
(FR) L'invention concerne un dispositif de rentrée (1) pour des procédures de recanalisation d'un vaisseau artériel par une technique intraluminale ou sous-intimale qui comprend un cathéter (10) ayant une extrémité distale (12) avec une pointe incurvée (13) d'un angle (a) compris entre 30° et 90°, et un stylet à pointe inclinée (2) destiné à être inséré dans la lumière interne du cathéter (10) pour sortir d'une ouverture distale (14) de celui-ci. Le stylet à pointe inclinée (2) est constitué d'un matériau métallique et a une extrémité distale (22) avec une pointe incurvée (23) se terminant par un sommet de pointe (24). En particulier, l'extrémité distale (22) du stylet à pointe inclinée (2) est effilée et a une longueur comprise entre 3 cm et 5 cm, et la pointe incurvée (23) est courbée selon un angle (β) compris entre 30° et 50° : une telle structure rend le sommet (24) également réglable à l'extérieur du plan bidimensionnel défini par la pointe incurvée (13) du cathéter pour faciliter la pénétration de la paroi artérielle.
