The patient was undergoing a thrombectomy procedure using a penumbra system aspiration pump max 110 (pump max).During the procedure, the physician noticed that the pump max had gotten very warm and smelled hot.It was reported that the pump max also had reduced aspiration power; therefore, it was removed.The procedure was completed using manual aspiration with a syringe.The patient had deficits post procedure caused by the index stroke that the patient was originally being treated for.

Results: the pump max was able to power on and produce a vacuum pressure of approximately -29.0 inhg.The pump max was ran continuously for approximately 30 minutes and the vacuum pressure remained the same and no unusual smell was noticed.Conclusions: evaluation of the returned pump max revealed an undamaged device.During functional testing, the pump max was powered on and was able to produce a vacuum pressure within specification.The reported smell and reduce aspiration power could not be confirmed.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.
