The cracks in the EndoWrist monopolar curved scissors can cause leaks that "may create a pathway for electrosurgical energy to leak to tissue during use and potentially cause thermal injury," according to the warning. "These micro-cracks may not be visible to the user."

"To date, in over a million surgeries with these instruments, the company has no confirmed evidence of patient injury attributable to this issue," Intuitive told CNBC today.
