Additional Manufacturer Narrative
Device evaluated by mfr: the device was returned for analysis.The stent was detached from the balloon.Stent damage was noted along the entire length of the stent with stent struts squashed.The balloon did not appear to have been subjected to any positive pressure.As part of the device analysis, the device was attached to an encore inflation unit and the balloon was inflated to its rated burst pressure with no leaks or restrictions noted.The balloon deflated within 12.5 seconds with no issues noted.A visual and tactile examination identified no issues along the length of the catheter device.No other issues were identified during the product analysis.The manufacturing batch record review confirmed that the device met all material, assembly and performance specifications.The most probable root cause is operational context as device performance was limited due to anatomical procedural factors.(b)(4).
