It is used for stone manipulation and removal from the urinary system. Its nitinol memory structure allows it to keep its shape and turn easily in difficult applications. Its unique zero-pointed structure is placed in the anatomical structure in the calyx and ureter and surrounds the stone. This structure does not damage neighboring tissues as well as prevents perforation. 2.4, 3 and 4 Fr variants facilitate the continuous deflexion of the flexible ureteroscope. The helical basket adds a plus feature to capture the stone. It is offered in sterile disposable packages. We have different handle models that meet different usage needs.
