The reported packaging lot (5293472) for item number h965457591 had purchased component item number 10610018 (angiodynamics lot 639175 [sl# pl01598]) and (b)(4) [sl# pl01763]) packaged in it.A review of the device history records was performed for the indicated packaging and component lots for any deviations related to the reported defect of the complaint.The review confirms that the lots met all material, assembly and performance specifications.The recent angiodynamics complaint report was reviewed for the mini stick product family and the failure mode "guidewire fractured/migrated." no adverse trend was identified.Although the guidewire was not returned for evaluation, a supplier corrective action response (scar) was sent to heraeus medical, angiodynamics' guidewire supplier, for information purposes.Although the exact cause of the reported event is unable to be determined without a sample evaluation, a possible root cause for the fractured guidewire may be the end user pulled the wire back through the needle.The directions for use packaged with the mini stick states: "the guidewire should not be withdrawn through the introducer needle.If the guidewire must be withdrawn while still inside the needle, simultaneously remove both the needle and the wire as a unit to prevent the needle from damaging the guidewire." ((b)(4)).
