Kyphoplasty and vertebroplasty expose physicians to such high levels of radiation that some have developed cataracts and some have to stop operating to avoid exceeding their maximum radiation dose. Protect your physicians during cement injection with Medtronic's Kyphon cement delivery system (CDS). CDS allows physicians to deliver multiple types of cement up to 48 inches away from the radiation source without sacrificing tactile feel. Operation only requires one hand. Each trigger squeeze dispenses a precise amount of cement. The device reduces radiation exposure during cementing by 70%.
