The patient was undergoing a thrombectomy procedure using a penumbra system aspiration pump max 220v (pump max).During the procedure, the aspiration tubing (tubing) was accidently connected directly to the pump max rather than the canister.Consequently, blood was aspirated into the pump max and, therefore, it was removed.The procedure was completed using a new pump max.There was no report of an adverse effect to the patient.
|
Results: dried blood was on the pump housing and inside the vacuum inlet.Conclusions: evaluation of the returned pump max confirmed blood was aspirated into the pump.If fluid enters the vacuum pump assembly, the pump may not function properly.Penumbra pumps are visually inspected and functionally tested during incoming quality inspection.The manufacturing records for this lot were reviewed and did not reveal any outstanding discrepancies, design, or quality concerns.
