A collection of devices intended to assist treatment of a blocked ureter and to help maintain ureteral patency through natural orifice or percutaneous access. It includes a polymeric ureteral stent, a device(s) intended to trap, retrieve, and/or manipulate urinary stones (e.g., urinary stone retrieval basket), and typically devices associated with access/stent-implantation (e.g., guidewire). This is a single-use device.
