(b)(4).As received, the specimen presents an overall length of 151.60cm and a finished diameter of.03415" to.03425".A gage bushing certified to be.0355" was passed over the length of the device.The specimen presents numerous bends and offset coil damage over the distal 7.0cm and scattered bends and scraped ptfe coating over the length of the device.The specimen presents scraped ptfe coating located 51.0 to 57.5cm and 112.0 to 116.0cm from the distal tip, with a 3mm stretched coil segment 31.0 to 31.3cm from the distal tip.The specimen also presents dried deposits of blood-like material and other biomaterial deposits on and between the coil wraps and within the coil lumen throughout the length of the device, consistent with clinical use.No other damage or inconsistencies are noted to the specimen at this time.All joints appear to be correct and intact by visual examination and by non-destructive testing.Except where noted, the specimen device appears visually and dimensionally correct.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).
