Age at time of event: 18 years or older.(b)(4).Device evaluated by mfr: the device was returned for analysis.A visual examination on the balloon identified no issues with the balloon.The balloon was not folded.There was no damage to the blades.A visual examination on the catheter shaft identified a break in the inner shaft of the balloon approximately 1mm proximal to the distal end of the tip.As a result of the break in the inner shaft, liquid leaked out through the tip during attempts to inflate the balloon.The break is consistent with excessive tensile force having been applied to the shaft during the removal of the balloon protector.The balloon protector was not received for analysis.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 investigation conclusion is handling damage as the complaint was caused by handling of the device or portion of the device without direct patient contact.(b)(4).

Reportable based on device analysis completed on 15-mar-2018.It was reported that difficulty in withdrawing the catheter from the protective hoop and balloon rupture occurred.The 75% stenosed target lesion was located in the mildly tortuous and mildly calcified superficial femoral artery (sfa).A 4.00mm/1.5cm/140cm small peripheral cutting balloon¿ was selected for use.During preparation, when taking out the balloon catheter from the protective hoop, it was noted that slight resistance was felt.Furthermore, the balloon catheter was advanced to the lesion; however, it was noted that at first inflation, balloon ruptured at "4atm".The procedure was completed with a different device.No patient complications were reported.However, device analysis revealed a break in the inner shaft approximately 1mm proximal to the distal end of the tip.
