Kinking implies a focal, reversible narrowing of the lumen which may have many root causes.Significant kinks will be identified prior to use, at which time the cannula can be exchanged for another.Smaller kinks that occur during the procedure may be due to anatomic anomalies and not the device.However, the kinking may result in a cannula exchange that disrupts cardiopulmonary bypass.The device was not returned for evaluation, as the device availability is unknown.The root cause of this event remains indeterminable.If new information becomes available, a supplemental report will be submitted.The device history record (dhr) was reviewed and showed that this device met all manufacturing and sterilization specifications for product release prior to distribution.No issues were identified that would have impacted this event.Edwards will continue to review and monitor all events.Trends are monitored on a monthly basis and if action is required, appropriate investigation will be performed.
