Nitinol Retrieval Coil

Stone Cone™ Nitinol Retrieval Coil product shot.
Stone Cone™ Nitinol Retrieval Coil product shot.
Designed to sweep multiple stone fragments.

The Stone Cone Nitinol Retrieval Coil is designed to act as an effective backboard, minimizing retropulsion to keep the procedure simple. It is designed to help increase procedural efficiency by minimizing retropulsion of stones up the ureter and into the kidney — potentially eliminating the need for a flexible scope during the case.1
