Meet the One-Of-A-Kind CVAC System

Most kidney stone treatments leave stone fragments behind in the body.1 These leftover pieces are linked to more unplanned post-procedure health events, such as ER visits, hospital stays, and additional procedures.*,2

 

That’s why the unique, vacuum-based CVAC System is designed to help your physician completely remove kidney stones during the procedure itself.
