The XenX device combines several features in one device which facilitate an endoscopic procedure. The XenX easily tracks past ureteral kidney stone and is navigated under fluoroscopy like a urologic guidewire. Once in place, a self expandable braided structure is deployed to block the ureteral lumen and prevent stone particle migration towards the kidney. The braided structure enables a constant irrigation flow for clear uretroscopic vision during the procedure. Following stone fragmentation and if required the physician can choose to propagate a urinary stent over the device for ureteral placement.
