The impella cp catheter failed while implanted in patient.The flow started out between 3.2 and 3.4 and then dropped to 1.2.The catheter was removed, flushed out, and re-implanted, but flow never went above 1.2.It was eventually replaced with a 2.5 l pump that was not sufficient to support the patient.A right axillary cutdown was performed and 5l pump was place.Although unrelated to the pump failure, the patient expired in the operating room.Per site reporter: (b)(4) reps were present during surgery.The device will be returned for failure analysis.
