The actual sample has not been received for analysis.Retained samples of incident code and lot number were retrieved for analysis.The primary packs of retain samples were visually inspected for attribute defects like pseudo seal, pin hole, product in seal, press marks on pack but no such defects were observed.The primary packs were opened and sutures and needles were found intact.The sutures were physically inspected for any attribute defects like kinks, weak spots, broken piece, fray, brittleness, detached needles but no such defects were observed.The needles were inspected for any attribute defects like bend, cracked barrel, fins but no such defects were observed.The retain samples were tested for knot pull tensile strength & needle pull test and found to meet the specification.From the above analysis, it is evident that there was no issue related to the suture quality and processing of this incident lot.

Product complaint # : (b)(4).A failed suture needle was submitted for fractographic evaluation.A fracture was observed in the body of the sample and was received in two pieces.Only one of the mating fracture surfaces was examined for this evaluation, the mating fracture surface was not provided for this evaluation.A microscope was used to examine the fracture surfaces and surrounding area of the needles.The fracture surfaces were examined in multiple locations in order to determine the fracture mode.The evaluation revealed the fracture was composed of both microvoid coalescence, which is evidence of a ductile overload failure and intragranular, which is evidence of a brittle failure.This was a mixed mode fracture.The manufacturing records were reviewed and the manufacturing/packaging criteria were met prior to the release of this batch.
