(b)(4).During processing of this complaint, attempts were made to obtain complete event, patient and device information.(b)(4).The device was not returned for analysis.A review of the lot history record revealed no manufacturing nonconformities that would have contributed to this complaint.Additionally, a review of the complaint history identified no similar incidents from this lot.It was reported that once the 3.0x38mm xience prime stent was deployed, negative pressure was held for a few seconds prior to retraction of the stent delivery system which became stuck on the implanted stent.It should be noted the xience prime long length everolimus eluting coronary stent system instructions for use states: deflate the balloon by pulling negative on the inflation device.Larger and longer balloons will take more time (up to 30 seconds) to deflate than smaller and shorter balloons.Confirm balloon deflation under fluoroscopy and wait 10 - 15 seconds longer.The investigation determined that the reported difficult to remove appears to be related to the use error.Based on the information reviewed, there is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.

It was reported that the procedure was to treat a 99% stenosed, mildly tortuous, and heavily calcified lesion in the mid right coronary artery.A 3.0x38mm xience prime stent was deployed; however, negative pressure was only held for a few seconds and during retrieval of the stent delivery system (sds) it became stuck with the implanted stent.The sds, guide wire, and delivery catheter were all removed as a unit and the procedure was completed with the stent being successfully implanted.There was no clinically significant delay in the procedure and no adverse patient effects.No additional information was provided.
