Device evaluated by mfr: the complaint device was returned for evaluation.A kink was observed in the sheath assembly at 4.0 cm from femoral marker to the proximal end.The telescope assembly was not able to properly pull back, advance, or retract.During image characterization testing, no image appeared in the system due to electrical open at distal.The white marker band was found completely intact and visible in corrected location on the shaft.The distance from the distal end of the transducer housing to the distal edge of the ro marker measured 5.5 mm.The observed distance is within specification.The distance from the distal tip to the femoral marker was measured as 109.8 cm.The observed distance is not within specification.The imaging window has a flatten section and appears to be about 5 cm longer then specification.The manufacturing batch record review confirmed that the device met all material, assembly and performance specifications.The most probable root cause was unable to be determined.(b)(4).
