Northampton hospital's new diamond-tipped drill blasts calcium off arteries at 170,000rpm A new treatment that drills hardened calcium off of severely blocked arteries in the heart has come to Northampton General Hospital.
The specialist surgery, known as "rotablation", uses a 2mm diamond-dust tipped burr rotating at 170,000rpm to blast through coronary lesions.
It opens up new options for patients who would otherwise need open-heart surgery. Northampton Chronicle and Echo
