(b)(4).Additional information: concomitant medical products, device evaluated by mfr.Device evaluation summary: the actual device was received for evaluation.A fracture was observed at the tip of the needle.One side of the needle was received, the mating fracture surface was not provided for this evaluation.The fracture surfaces were microscopically examined in multiple locations in order to determine the fracture mode.The evaluation revealed the fracture was composed of microvoid coalescence, which is evidence of a ductile overload failure.Mechanical damage observed coincidental to the fracture provides additional evidence that the failure was induced by mechanical deformation leading to ductile overload.This was a ductile fracture.The manufacturing records were reviewed, and the manufacturing/packaging criteria were met prior to the release of this batch.The evidence of this examination indicates that the breakage occurred at the tip of the needle during use due to tensile overload.There is no evidence of any material flaw or defect that would cause premature failure.In order to avoid this kind of damage grasp the needle in an area one-third (1/3) to one-half (1/2) of the distance from the attachment end to the point.Representative samples were received for analysis an empty box and eighteen unopened samples of product code j259, lot mp2304.During the visual inspection of thirteen unopened samples, no defects were found on the packages.The samples were opened, and the swage and attachment area were as expected; also, the tip and body of the needles were examined no defects or needle breakage were observed.The sutures were dispensed without problems and examined along of the strand and no defect were observed.Also, the samples were tested by resistance test to needle and the needles met the requirements.Per the condition of the representative samples, no performance breakage needle were found on the sample.
