Abstract: Provided herein are devices related to the removal of uroliths, including kidney, ureteral and/or bladder stones. In one embodiment, the device comprises a mesh or sponge that is removably connected to a catheter, adapted for the removal of urolith fragments of the size 2 mm or less. In one embodiment, the device includes a catheter that is either solid or hollow, the latter for the irrigation of various types of fluid (either standard irrigation fluid (e.g. saline or water) or a material (e.g. blood, fibrin glue, etc.) that would form a clot like substance within the interstices of the device thereby increasing its ability to entrap fragments within the interstices of the basket or nearby.
