Abstract: The present technology relates to ureteroscopy, laser ablation of ureteral and renal stone, capture and removal of stone fragments. In one embodiment, the device includes an optical instrument operably connected to a large vacuum channel that is about 1.5 mm to about 8.0 mm in width. In another embodiment, the device includes two single-time use disposable or potentially reusable units, such as a large vacuum endoscope removal tip and a wireless and modular battery-powered handpiece.

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.
