Updated on

Carson Block, the renowned short-seller and founder of research firm Muddy Waters LLC, has taken a short position in St. Jude Medical Inc., denouncing the security of its cardiac devices in an effort that could derail the company’s purchase by Abbott Laboratories.

In a report to investors Thursday, Block warned that tens of thousands of Americans are living with ticking time bombs: St. Jude pacemakers and defibrillators that are easily compromised, causing potentially fatal disruptions.
