During preparation for the procedure, the technician found that the penumbra system aspiration pump max 220 (pump max) would not turn on and, therefore, it was not used in the procedure.The procedure was completed using manual aspiration.

Results: a pipe cleaner was inserted into the vacuum inlet and blood was present.Conclusions: evaluation of the returned pump max revealed that the pump had blood inside the vacuum inlet.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 likely contributed to the pump not producing aspiration.During the functional test, the pump max was powered on and the fan ran but no aspiration was observed.Penumbra pumps are visually inspected and functionally tested during incoming inspection by quality.The manufacturing records for this lot were reviewed and did not reveal any outstanding discrepancies, design, or quality concerns.
