It was reported that the procedure was to treat a lesion in the non-calcified, non-tortuous mid right coronary artery.Due to resistance with the guiding catheter during advancement of the 3.0x18 mm xience prime stent delivery system (sds), the device failed to cross the lesion.After several attempts were made, force was applied and the proximal shaft was kinked.The kink location was outside the patient.Resistance was felt with the guiding catheter during retraction and the sds was removed as a whole unit.The procedure was successfully completed with a same size xience prime stent.There were no adverse patient effects and no reported clinically significant delay in the procedure.No additional information was provided.

(b)(4).The device was returned for analysis.The reported shaft kink was able to be confirmed.The reported difficulty to position and the reported difficulty to remove were unable to be confirmed.Based on a visual, dimensional and functional inspection of the returned device, there is no indication of a product quality issue with respect to manufacture, design or labeling.Based on the information provided, the reported difficulties appear to be related to circumstances of the procedure.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot.Additionally, a review of the complaint history identified no other similar incidents from this lot.It should be noted that the xience prime everolimus eluting coronary stent system instructions for use states: if unusual resistance is felt before the stent exits the guiding catheter, do not force passage.Resistance may indicate a problem and the use of excessive force may result in stent damage or dislodgement.Maintain guide wire placement across the lesion and remove the delivery system and guiding catheter as a single unit.Based on the information reviewed, there is no evidence to indicate the presence a potential quality issue with respect to manufacture, design or labeling.
