The device was not returned for analysis.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Additionally, a review of the complaint history identified no other incidents from this lot.The investigation was unable to determine a conclusive cause for the reported deflation issues; however, factors that may contribute to deflation issues include, but are not limited to, manufacturing damage, contrast mixing, bent/kinked shaft while inside the anatomy affecting the deflation lumen and/or stretched outer member (om) thereby reducing the deflation lumen.There is no indication of a product quality issue with respect to manufacture, design or labeling.

It was reported that the procedure was to treat a mildly calcified, tortuous and 90% stenosed lesion in the distal right coronary artery.Following pre-dilatation with a non-abbott balloon, a 4.0x18mm xience skypoint stent was advanced to the lesion and the stent deployed and implanted at 14 atmospheres for 10 seconds; however, deflation seemed slow.The delivery system was successfully removed, without reported issue.There was no adverse patient effect or a clinically significant delay.No additional information was provided.
