Title
(EN) TRANSURETHRAL CATHETER DEVICE FOR BLEEDING CONTROL IN PELVIC FRACTURES
(FR) DISPOSITIF DE CATHÉTER TRANSURÉTRAL POUR LE CONTRÔLE DU SAIGNEMENT DANS DES FRACTURES PELVIENNES
Abstract
(EN)
The inventions relates to a transurethral catheter device for bleeding control in pelvic fractures. The catheter device comprises an expandable body assembly with at least one expandable body. The expandable body assembly comprises a proximal portion, a center portion and a distal portion. The expandable body assembly is configured to be expanded from a collapsed state to an expanded state by expanding the at least one expandable body. The expandable body assembly is further configured to be inserted into the urinary bladder of a patient via the urethra in the collapsed state. In the expanded state, the proximal portion has a length l1 and a width w1, the center portion a length l2 and a width w2, the distal portion a length l3 and a width w3, and the expandable body assembly a total length l. A displacement volume V of the expandable body assembly in the expanded state is larger than 0.5 liters. The width w2 is smaller than 50% of the width w3. The width w1 is larger than a width w1 of the proximal portion in the collapsed state and the width w3 is larger than a width w3 of the distal portion in the collapsed state. The length l1 is smaller than25% of the total length l. This allows for arranging the expandable body assembly in the expanded state in the urinary bladder such that the proximal portion is adjacent to the internal urethral orifice of the urinary bladder and the center portion is adjacent to the ureter orifices of the urinary bladder, but not in contact with the ureter orifices.

L'invention concerne un dispositif de cathéter transurétral pour le contrôle du saignement dans des fractures pelviennes. Le dispositif de cathéter comprend un ensemble corps extensible avec au moins un corps extensible. L'ensemble corps extensible comprend une partie proximale, une partie centrale et une partie distale. L'ensemble corps extensible est configuré pour être déployé d'un état plié à un état déployé par expansion du ou des corps extensibles. L'ensemble corps extensible est en outre conçu pour être inséré dans la vessie d'un patient par l'intermédiaire de l'urètre à l'état plié. Dans l'état déployé, la partie proximale a une longueur l i et une largeurW i, la partie centrale a une longueur 12 et une largeur w2, la partie distale a une longueur l3 et une largeur W3, et l'ensemble corps extensible a une longueur totale 1. Un volume de déplacement V de l'ensemble corps extensible dans l'état déployé est supérieur à0.5 litres. La largeurW2 est inférieure à50% de la largeur w3. La largeurWi est supérieure à une Largeur fvi de la partie proximale dans l'état plié et la largeur w3 est supérieure à une largeur w3 de la partie distale dans l'état plié. La longueur l \ est inférieure à25% de la longueur totale 1. Ceci permet d'agencer l'ensemble corps extensible dans l'état déployé dans la vessie de telle sorte que la partie proximale est adjacente à l'orifice urétral interne de la vessie et la partie centrale est adjacente aux orifices urétéraux de la vessie, mais pas en contact avec les orifices urétéraux.
