Medtronic Lost Patient Records in Cyber Attack

Medtronic Inc., the world's largest stand-alone medical device maker, was the victim of a cyber attack and lost some patient records in separate incidents last year, it said in a regulatory filing. "Medtronic, along with two other large medical device manufacturers, discovered an unauthorized intrusion to our systems that was believed to originate from hackers in Asia," the company said in a 10-K filing with the U.S. Securities and Exchange Commission.
