Additional Manufacturer Narrative
Device is a combination product.(b)(4).Device evaluated by mfr.: stent delivery system was returned for analysis.A visual examination of the stent found that proximal stent rows 1, 4 and 5 were damaged and a stent strut was lifted and pulled distally.The undamaged section of the crimped stent od (outer diameter) was measured and the result 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 a hypotube kink 450 mm distal from the distal end of the strain relief.This type of damage is consistent with excessive force being applied to the delivery system.A visual and tactile examination of the outer and the inner lumen and mid-shaft section found no issues with the shaft polymer extrusion.No other issues were identified during the product analysis.The most probable root cause is operational context as device performance was limited due to anatomical/procedural factors.(b)(4).
