The clamp device is essential to occlude the aorta and provide the necessary cardiac isolation required to perform minimally invasive cardiac surgery procedures.If the balloon bursts during a procedure, the heart would fill and warm, the operative site may be obscured and the procedure may need to convert to an open procedure.In this case, the patient was noted to be fine.This device was not returned for evaluation at this time and follow up is in progress.The investigation is on-going and a supplemental report will be submitted upon receipt of additional information.
