A software designer is suing a California company, claiming its medical device used to treat aneurysms malfunctioned and caused him to suffer brain damage.
The Penumbra Coil 400 was used to treat an aneurysm Dennis Montgomery suffered in 2013, according to his lawyer, Peter Mullenix. He said during the surgery at Overlake Hospital in Bellevue, the doctor placed 90 percent of the coil into the aneurysm, but the last 10 percent got stuck in the intracranial artery.
