(b)(4).The customer returned one unopened sac kit for analysis.The kit was opened to further analyze the components.Visual inspection of the components revealed no kinking or bending of the guide wire.However, major bending of the guide wire tubing was observed.Several creases and folds were also observed on the product packaging.The damage observed is consistent with defects related to storage and shipping.Both welds were present and appeared full and spherical.The packaging clearly states, "do not bend".The guide wire total length measured 350 mm which is within the specifications of 345-355mm.The guide wire outer diameter (od) measured 0.51mm which is within the specifications of 0.508mm-0.533mm.Functional inspection of the guide wire was performed per the instructions-for-use (ifu) provided with the kit which states, "insert desired tip of spring-wire guide through introducer needle into artery (until depth-marking [if provided] on wire enters hub of needle).Thread tip of indwelling catheter over spring-wire guide." the undamaged portions of the guide wire were threaded through the returned 20 ga introducer needle with no resistance.A manual tug test confirmed the distal and proximal welds were attached.The manufacturing site was previously consulted regarding the observed failure mode for related complaints.They indicated that the observed kink, in addition to the creasing in the packaging, is consistent with damage caused by shipping and handling.As part of the guide wire manufacturing process, each guidewire is passed through a ring gauge so it is unlikely that this defect would have been present prior to release from the manufacturing site.A device history record review was performed with no relevant findings.The guide wire product drawing was reviewed as part of this complaint investigation.The instructions for use (ifu) provided with this kit warns the user, "precaution: use of excessive force may damage catheter or guidewire.Do not use if package is damaged." corrective action is not required at this time as the probable root cause is storage and shipping related.The customer report of a kinked guide wire prior to use was not confirmed through complaint investigation of the returned sample.However, major bending of the guide wire tubing and several folds and creases on the outside packaging were observed.The guide wire met all relevant dimensional requirements, and a device history record review was performed with no relevant findings.The lidstock clearly states "do not bend." based on the customer description and the sample received, storage and shipping caused or contributed to this event.Teleflex will continue to monitor and trend for complaints of this nature.
