Results: dried blood was found on the pump housing.Blood was present inside the pump.Conclusions: evaluation of the returned pump max revealed blood within the vacuum assembly and on the pump housing.If the aspiration tubing is connected directly to the vacuum inlet rather than the pump canister, supplied by penumbra, blood will likely be aspirated directly into the vacuum assembly.Fluid being aspirated into the pump will likely cause the device to become non-functional.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.

The patient was undergoing a thrombectomy procedure using a penumbra system aspiration pump max 110 (pump max).During the procedure, the hospital staff accidentally connected the aspiration tubing (tubing) directly to the pump max rather than the canister.Consequently, blood was aspirated into the pump max and it stopped working; therefore, the pump max was disconnected.The procedure was completed using manual aspiration.There was no report of an adverse effect to the patient.
