Abstract
A stone retrieval suction device facilitates the retention and then relocation and/or removal of objects disposed in a patient's urinary system. The device includes an elongated member for placement in a channel of a flexible ureteroscope. The elongated member defines a suction passageway which extends longitudinally therethrough. The elongated member 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 for contacting and retaining an object when the suction is provided.
