A stone retrieval suction device (100) facilitates the retention and then relocation and/or removal of objects disposed in a patient's urinary system (208). The device includes an elongated member (102) for placement in a channel of a flexible ureteroscope (214). The elongated member defines a suction passageway which extends longitudinally therethrough. The elongated member (102) is flexible enough to bend with the flexible ureteroscope, and it is strong enough to prevent collapse of the suction passageway when suction is provided through the suction passageway by a vacuum source. The elongated member includes a distal portion (112) for contacting and retaining an object when the suction is provided.
L'invention concerne un dispositif d'aspiration et d'extraction de calculs rénaux (100), qui facilite la rétention puis le replacement et/ou le retrait d'objets disposés dans le système urinaire d'un patient (208). Le dispositif comprend un élément allongé (102) qui s'introduit dans un canal d'un urétérorénoscope souple (214). L'élément allongé délimite un passage d'aspiration longitudinal. L'élément allongé (102) est suffisamment souple pour se plier avec l'urétérorénoscope souple; il est suffisamment solide pour empêcher l'effondrement du passage d'aspiration lorsqu'une aspiration est appliquée par une source à vide, au travers du passage d'aspiration. L'élément allongé comprend une partie distale (112) qui va au contact d'un objet et le retient lorsque l'aspiration se produit.
