Manufacturer Narrative

The device was returned to edwards for evaluation.Evaluation is in progress.These cannulae are used to divert large volumes of blood between the patient circulation and the cardiopulmonary bypass machine during cardiac surgery and, on occasion, ecmo (off-label use).In this case, a massive amount of air was aspirated to the extra-corporeal tube right after the initiation of the cardiopulmonary bypass.The connector of the cannula was found loose.The cannula was pushed into the connector and secured.Based on the information received the cause of the event cannot be determined.Once additional information is received a supplemental mdr will be submitted.Edwards lifesciences will continue to monitor all reported events.

Event Description
|
Edwards received information that a small amount of air was aspirated to the extra-corporeal tube right after the cardiopulmonary bypass (cpb) was started during use.The duration was about ten (10) to fifteen (15) seconds.Cannula was checked then the connector was almost halfway off the 25fr cannula body.The cannula was pushed into the connector, but it was loose due to the blood adhesion.The connector was fixed by tie gun at two sites and operation was continued.The customer commented that the air was not aspirated into the patient and no blood leakage was observed from the connector.The customer also commented they checked the connection after surgery and the connector was looser to the cannula body when comparing to the same type of the products.The customer used it in the standard way and the connector was not disconnected and connected.The patient status was reported as "recovered".The cannula was used for minimally invasive cardiac surgery (mics) to perform mitral valvuloplasty.The customer requested a preventive action such as gluing the connector.The device will be returned for evaluation.

Edwards received information that a small amount of air was aspirated to the extra-corporeal tube right after the cardiopulmonary bypass (cpb) was started during use.The duration of air aspiration was about ten (10) to fifteen (15) seconds after the cpb was started.Cannula was checked then the connector was almost halfway off the 25fr cannula body.The cannula was pushed into the connector, but it was loose due to the blood adhesion.The connector was fixed by tie gun at two sites and operation was continued.The problem occurred within ten (10) minutes after the cannula was inserted to the patient.The cpb was not pulling vacuum on the venous side as the cpb was just started.The cpb had drawn about 1.5 litter of blood by the gravity drainage but it was not much air to cause air block.The air was not aspirated into the patient and no blood leakage was observed from the connector.After surgery, the connection was checked and the connector was looser to the cannula body when comparing to other products of the same model.The customer commented that maybe it was related to blood adhesion on the connector.The customer used it in the standard way and the connector was not disconnected and connected.The patient status was reported as "recovered".The cannula was used for minimally invasive cardiac surgery (mics) to perform mitral valvuloplasty.The total cpb time was two-hundred seventy-one (271) minutes.The customer requested a preventive action such as gluing the connector.The device was returned for evaluation.

H3.Device evaluation: customer complaint of disconnected connector was not confirmed with assessment.Device was returned with visible traces of blood and was examined in the biohazard area of the lab.As received, the connector of the cannula was intact and remained attached to the rest of the cannula.Connector was not loose and would not disconnect from cannula when manipulated.No visual damage or other abnormalities were found to the returned device.Photos provided appeared consistent with lab findings.H10.Additional manufacturer narrative: updated sections b5, d4 (expiration date), h3, h4, and h6 (method).Manufacturing records were reviewed and no non-conformities were recorded that would have contributed to this event.
