A stent for assisting urinary release in a male patient includes a first segment, a second segment, and a connecting member disposed between the first and second segments. The first segment includes a multi-winged malecot. When the stent is properly positioned within the patient's urinary system, the first segment is located on one side of the external sphincter with the multi- winged malecot located within the bladder to inhibit migration of the stent, and the second segment is located on the other side of the external sphincter and also tends to inhibit migration of the stent. The connecting segment is sized to extend through the external sphincter to couple the first and second segments together while not interfering with the normal operation of the external sphincter.
Un stent pour aider l'évacuation urinaire chez un patient de sexe masculin inclut un premier segment, un segment et un élément de liaison entre les deux segments. Le premier segment inclut un dispositif de Malécot à plusieurs branches. Lorsque le stent est correctement placé dans le système urinaire du patient, le premier segment est situé d'un côté du sphincter, le dispositif de Malécot à plusieurs branches étant situé à l'intérieur de la vessie de façon à bloquer la migration du stent, le second segment se trouvant de l'autre côté du sphincter externe, ayant tendance lui-même à bloquer la migration du stent. Les dimensions de l'élément de liaison sont prévue pour la traversée du sphincter externe de façon à assurer un couplage entre les deux segments sans interférer avec le fonctionnement normal du sphincter externe.
