Customer complaint of pinhole cannula leakage was confirmed with assessment.Device was returned with visible traces of blood and examined in the biohazard area of the lab.As received, wire reinforced section of the cannula body was observed to be kinked.A leak test was performed on the cannula and leakage was observed from the cannula body.No other visual damage, contamination, or other abnormalities were found to the device.If device is used during cardiopulmonary bypass (cpb), leaks in devices with high flow, such as arterial or venous cannulae, will most likely require an exchange of the device.This will require a temporary interruption of cpb.Since the patient¿s blood flow is dependent on cpb during this portion of the procedure the risk of injury is not remote.The root cause of this event cannot be determined at this time.The instructions for use (ifu) warns, ¿wire reinforced cannulae should be clamped in the non-reinforced section located at the connector end since clamping of the reinforced section may produce permanent cannula deformation, thereby impeding flow through the cannula and risking puncture or tearing of the cannula." the device history record (dhr) review was completed and this device passed all manufacturing and sterilization inspections prior to release for distribution.There were no issues identified that would have impacted this event.Edwards will continue to review and monitor all reported events.Trends are monitored on a monthly basis and if action is required, appropriate investigation will be performed.
