This cannula is used to divert large volumes of blood from the heart to the cardiopulmonary bypass machine during cardiac surgery procedures.If not detected prior to use, the bypass machine may alarm for decreased flow.A partial or complete separation will require exchange of the cannula, temporary interruption of bypass, and in a worst case scenario retrieval of the device fragment.Depending on the location of the fracture/separation, it may also result in significant blood loss and the potential for injury is not remote.In this case, the connector of a cannula almost came apart during an ecmo insertion and there was no injury to the patient.The device was not returned for evaluation at this time.Therefore, the root cause for the event remains indeterminable.The device history record (dhr) review is pending.A supplemental report will be submitted upon completion of the dhr review.A supplemental report will also be submitted if the device is returned and a product evaluation is completed.

It was reported that the connector of a venous cannulae almost came apart during an ecmo insertion.As reported, the connector came off the end of a 22fr venous cannulae cannula.The cannula was in the patient¿s groin.The doctor had just connected it to the ecmo circuit and was attempting to push the tubing on farther when the connector came out of the cannula.Ecmo was discontinued but air had entered the circuit, so a new circuit had to be set up and used.The doctor used the cannula, (still positioned in the groin), placed another 3/8x3/8 connector in place of the one that came off the cannula and went back on ecmo.There was no injury to the patient.
