As reported, during a percutaneous transluminal angioplasty (pta) the smart control 8 x 80 stent delivery system was attempted to be delivered to the intended target lesion.It was noted that the distal tip of the catheter was frayed.Therefore, the physician stopped using it, and new smart control was used instead.The procedure was finished successfully.There was no reported patient injury.The product was clinically used and it will not be returned for analysis.The target lesion was the superficial femoral artery (sfa).The lesion was reported to be: mildly calcified and not tortuous.The lesion was crossed with an unknown guidewire.Additional information has been requested.

Complaint conclusion: during an angioplasty, the physician had difficulty tracking a smart control 8 x 80mm stent delivery system (sds) to the target lesion and noted that the distal tip of the sds was frayed.The device was exchanged and the procedure successfully completed with no reported patient injury.The event involved a patient undergoing angioplasty of a mildly calcified, non-tortuous lesion in the superficial femoral artery.The lesion was successfully crossed with an unknown guidewire.The site reported that the sds packaging was inspected prior to use and no damages were noted.No difficulty was experienced when removing the device from the packaging and the device was noted to be un-damaged.The product was prepped according to the instructions for use (ifu) with no problems experienced.The smart control sds was loaded on the guidewire but difficulty was experienced in tracking the device to the target lesion.The physician noted that the distal tip of the sds was frayed.It is unclear from the report whether this damage was noted after product removal or not.The procedure was completed with a similar device with no reported patient injury.The product was not returned for evaluation.A review of the manufacturing records revealed that this lot of products met specification prior to release.The product ifu details that if resistance is met during delivery system introduction, the system should be withdrawn and another system should be used.Pushing the sds against resistance, which can be encountered during sds advancement through calcified, tortuous or stenotic vasculature, can cause the outer member to compress.Based on the limited information available for review, it is not possible to determine what factors may have contributed to the reported issue.Without the return of the device for analysis, the reported customer complaint could not be confirmed and no determination of possible contributing factors could be made.Based on the device history record review, there is no indication that the event is related to the device manufacturing process.Therefore, no corrective actions will be taken at this time.
