Age at the time of event: 18 years or older.The device was returned together with a non bsc introducer sheath.A visual examination of the balloon noted that the balloon was unfolded and crinkled which indicates that the balloon had been inflated and the crinkling of the balloon material may have occurred during attempts to remove the device.Blood was also noted within the balloon material which is evidence of a device leak.The device was then attached to an encore inflation unit and vacuum was applied.The device was then removed from the torn introducer sheath; however, due to the condition of the balloon material, resistance was encountered during withdrawal of the balloon from the hub of the introducer sheath.The device was again attached to an encore inflation device filled with glycerol/h20 solution and positive pressure was applied; however, the balloon could not be inflated due to the presence of solidified blood within the inflation lumen and balloon.The device was soaked in a water bath and was removed from the bath and subsequently was reattached to an encore inflation device and positive pressure was applied; however, liquid was observed escaping from a pinhole leak in the balloon material approximately 9mm distal to the distal edge of the proximal markerband.No issues were noted with the balloon material.An examination of the device identified that one of the blades was slightly damaged on the device.A microscopic examination identified that 1mm of one of the blades was lifted from the balloon material.This damage can potentially be a result of the resistance encountered during the advancement or withdrawal of the device.The remaining 19mm of the blade and the entire pad was intact and fully bonded to the balloon material.All other blades were intact and fully bonded to the balloon material.No other issues were noted with the blades or pads.No issues noted as well with the tip or markerbands.A visual and tactile examination of the device observed multiple kinks along the length of the device.No other issues were noted with the shaft.The manufacturing batch record review confirmed that the device met all material, assembly and performance specifications.The investigation conclusion is operational context as the product meets the design & manufacture specification but due to anatomical/procedural factors encountered during the procedure, performance was limited.(b)(4).

Reportable based on device analysis completed on 20-dec-2017.It was reported that the non bsc introducer sheath became detached upon removal of the balloon catheter.The 90% target lesion was located on a mildly tortuous and mildly calcified shunt vessel.A 6.00mm / 2.0cm / 50cm otw peripheral cutting balloon¿ was inserted through a non bsc introducer sheath for percutaneous transluminal angioplasty.The balloon was inflated 3 times at 6atms respectively for 30seconds; however, it was noted that the non bsc introducer sheath became detached upon removal of the balloon catheter.There were no patient complications reported.However, device analysis results revealed that about 1mm from one of the blades became lifted.
