Manufacturing review: a manufacturing review was not required as this is the only complaint reported to date for this product and lot.Investigation summary: one of the introducer sheath segment from the denali filter delivery system was returned for evaluation.During the visual evaluation, a filter arm was noted to be perforating the sheath near the distal end of the sheath hub.An x-ray image was taken and the filter was noted to be within the sheath segment.Therefore the investigation is confirmed for the failure to advance and identified material puncture issue as the filter was noted stuck inside the sheath and the filter limb was perforated the introducer sheath.A definitive root cause for the reported failure to advance and identified material puncture issue could not be determined based upon the provided information.Labeling review: a review of product labeling documentation (e.G., procedural instructions, indications, warnings, precautions, cautions, possible complications, contraindications, nursing guide, and unit label) did not find any product labeling inadequacy.(expiry date: 03/2025).
