Title
(EN) APPARATUS AND METHOD FOR ADVANCING CATHETERS OR OTHER MEDICAL DEVICES THROUGH A LUMEN
(FR) APPAREIL ET PROCÉDÉ POUR FAIRE AVANCER DES CATHÉTERS OU D'AUTRES DISPOSITIFS MÉDICAUX À TRAVERS UNE LUMIÈRE
Abstract
(EN)
Devices, systems, and methods are disclosed that help deliver an outer catheter or other medical devices to locations within a patient's body. The device comprises a transporter catheter configured to be located in a lumen of an outer catheter, the transporter catheter comprising a shaft, at least one orienting balloon and at least one anchoring balloon, the orienting balloon positioned on the shaft adjacent to the distal end of the shaft and configured to slidably engage an inner surface of a patient's vasculature, the anchoring balloon located on the shaft between the orienting balloon and the proximal end of the shaft, the anchoring balloon configured to non-slidably anchor the transporter catheter to the outer catheter, and the transporter catheter is configured to be pushed and/or torqued to advance and maneuver the outer catheter through a patient's vasculature.

L'invention concerne des dispositifs, des systèmes et des procédés qui aident à poser un cathéter externe ou d'autres dispositifs médicaux à des emplacements dans le corps d'un patient. Le dispositif comprend un cathéter de transport configuré pour être situé dans une lumière d'un cathéter externe, le cathéter de transport comprenant un arbre, au moins un ballonnet d'orientation et au moins un ballonnet d'ancrage, le ballonnet d'orientation étant positionné sur l'arbre de manière adjacente à l'extrémité distale de l'arbre et configuré pour mettre en prise de manière coulissante une surface interne du système vasculaire d'un patient, le ballonnet d'ancrage étant situé sur l'arbre entre le ballonnet d'orientation et l'extrémité proximale de l'arbre, le ballonnet d'ancrage étant configuré pour ancrer le cathéter de transport au cathéter externe de manière non-coulissante, et le cathéter de transport étant configuré pour être poussé et/ou soumis à un couple pour faire avancer et manœuvrer le cathéter externe à travers le système vasculaire d'un patient.
