Results: dried blood was observed throughout the penumbra system 3d revascularization device (psr3d).The delivery wire was kinked approximately 162.0 and 171.0 cm from the proximal end.Conclusions: evaluation of the returned device revealed it was removed from its packaging hoop and the packaging hoop was not returned for evaluation.The psr3d was re-loaded into a demonstration packaging hoop and removed from the packaging hoop without issue.Therefore, the root cause of the reported issue could not be determined.Further evaluation revealed the delivery wire was kinked and dried blood was observed throughout the psr3d.Since the psr3d was reportedly not used in the procedure, the root cause of this damage and blood could not be determined.Penumbra psr3ds are inspected during in-process inspection and during quality inspection after manufacturing.The manufacturing records for this lot were reviewed and did not reveal any outstanding discrepancies, design, or quality concerns.

During preparation for a thrombectomy procedure, a penumbra system 3d revascularization device (psr3d) would not come out of the dispenser hoop.The issue with the psr3d occurred prior to use and therefore, the psr3d was not used in the procedure.The procedure was completed using a new psr3d.
