Event Description
|
It was reported that the stent moved on balloon and stent damage occurred.Vascular access was obtained via radial artery.The 12x3.50mm, concentric and de novo target lesion with a bend of <=45 degrees was located in the mildly tortuous and mildly calcified ostial left anterior descending artery.After a choice floppy guidewire and a non-boston scientific guide catheter crossed the lesion, pre-dilatation was peformed with a non-boston scientific balloon catheter.A 12 x 3.50 promus premier drug-eluting stent was advanced; however, the stent failed to cross the lesion.The stent was deformed and moved from the balloon.The device was removed from the patient's body and the procedure was completed with another of same device.No patient complications were reported and the patient's status was stable.

Manufacturer Narrative

Device evaluated by mfr.: promus premier ous mr 12 x 3.50mm stent delivery system (sds) was returned for analysis.An examination of the crimped stent found the stent moved on the balloon, with distal stent struts pulled distally over the tip of the device.The crimped stent outer diameter measured during manufacture and was within maximum crimped stent profile measurement.The balloon cones were reviewed, and no issues were noted.The balloon wings were tightly wrapped and evenly folded and were not subjected to positive pressure.A visual and microscopic examination of the bumper tip showed no signs of damage.A visual and tactile examination of the hypotube found multiple hypotube kinks at several locations along the hypotube shaft.A visual examination of the outer and inner lumen and mid-shaft section found no issues along the shaft polymer extrusion.An attempt was made to load a recommended guide catheter but it could not be loaded through the tip due to the damaged stent covering the tip.No other issues were identified during the product analysis.
