(b)(4).Device evaluated by manufacturer: the complaint device was received for evaluation.Based on the returned condition of the device, the telescope assembly was not able to properly pull back, advance, or retract.Since the telescope cannot advance the transducer distal housing (tdh) to the most distal position, the distance from the distal end of the transducer housing to the tip of the catheter was not measured.Fluid was leaking from an open hole in the sheath lap joint from the femoral marker at the proximal end when the catheter was flushed.No other issues or defects were observed.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).
