(b)(4).Date sent to the fda: 08/16/2019.H3 device evaluation summary: the actual device components were received for evaluation.A fracture was observed in the body of sample a.The needle was received in two pieces, only one of the mating fracture surface was examined for this evaluation.A scanning electron microscope (sem) was used to examine the fracture surface and surrounding area of the needle.The fracture surface was 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, a cup-and-cone shaped fractures and macroscopic plastic deformation observed coincidental to the fracture provide additional evidence that the failure was induced by mechanical deformation leading to ductile overload.These 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 from mechanical deformation, indents and scratches, due to gripping, bending and overstressing of the needle. there is no evidence of any material flaw that would cause premature failure.H3 device evaluation summary: an empty opened box and twenty-two unopened samples of product code pdp6659, lot # pbu418 were received for evaluation.During the visual inspection of the thirteen samples, no defects were found on the packages.The samples were opened, and the swage and attachment area were noted to be as expected.No needles breakage was observed.The sutures were dispensed without problems and examined along of the strand and no defects were observed.Also, the sample was tested by resistance test to needle and met the requirements.The manufacturing records were reviewed, and the manufacturing/packaging criteria were met prior to the release of this batch.Per the conditions of the sample received, no performance breakage needle were found.Representative samples returned to support investigation of 2 device issues captured in reports 2210968-2019-84229 and 2210968-2019-84230.Analysis results have been included in follow-up reports for each.
