A visual inspection was performed on the returned device.The reported peeled/delaminated was confirmed.The reported difficult to advance could not be tested due to the device condition.A review of the production records and the corrective and preventive actions (capa) database was performed and revealed no indication of a product quality issue.Additionally, a query of the complaint handling database for the reported lot revealed no indication of a lot specific issue.The investigation was unable to determine a conclusive cause for the reported difficulties.It was reported that the guide wire encountered difficulty during advancement and was observed to have peeled polymer once removed from the anatomy.Factors that may contribute to difficulty during advancement include, but are not limited to, outer diameter of the guide wire, device support, buildup of procedural contaminants, user technique, challenging anatomy, interaction with accessory devices, and/or damage to the guide wire.Additionally, factors that may contribute to polymer peeling include, but are not limited to, material properties, equipment setup, inadvertent handling damage, device placement technique, guiding catheter support, anatomical conditions/patient anatomical morphology, inner diameter of guide wire lumen of delivery/supporting device, outer diameter of the guide wire, condition of the guide wire, condition of the delivery/supporting device, and coagulation of blood or procedural contaminates.In this case, based on the information provided, it is unknown what may have contributed to the reported polymer peeling or difficulty during advancement.Additionally, during analysis of the returned wire, an irregular texture was noted on the core.Fourier transform infrared spectroscopy (ftir) was performed on the texture, and it was identified to possibly be a component of skin lotion.It is unlikely this texture originated from manufacturing.There is no indication of a product quality issue with respect to manufacture, design, or labeling; therefore, no product-related corrective action will be implemented in this case.
