Event Description
|
Medtronic received information from the customer that a bio-medicus nextgen insertion kit was used as an arterial cannula for an emergency ascending aorta replacement.An issue was noticed after the procedure, that wire remnants at the tip of the cannula spring remained in the patient's blood vessel.The remnants in the blood vessel were confirmed by x-ray and were removed with an additional procedure.There was no adverse effect to the patient.Additional information received from the customer: the guidewire was pulled out with the guidewire clamped through the cannula with tube forceps (although it was unknown how much force it was clamped with).The guidewire broke and it remained inside the blood vessel about 20 to 30cm from the renal artery to the proximal.At the time of removal, even though it was pulled out from around the renal artery and warfarin was taken, it could be confirmed visually that a small amount of thrombus was adhering to the guidewire.It was not considered by the customer to be a product-derived defect.However, the event was submitted to medtronic calling attention to the event due to incorrect usage of the device.
