An attempt was made use an nc euphoria balloon catheter to pre-dilate a moderately tortuous, severely calcified lesion, with 80% proximal stenosis and 90% distal stenosis, in the mid-distal left-anterior descending artery.There was no damage noted to the device packaging.There were no issues noted when removing the device from the hoop.There was no difficulty removing either the outer protective sheath covering the balloon, or the stylette.The balloon was prepped in the hoop to activate the hydrophilic coating.The device was inspected with no issues noted.(b)(6) prep was performed with no issues.The lesion was pre-dilated.The device passed through a previously deployed stent.Resistance was not encountered when advancing the device and excessive force was not used.The device was not kinked or re-straightened during use.The balloon would not inflate.It is reported that a portion of the catheter detached during delivery through the vessel.The catheter was completely separated into two pieces at the site of balloon shaft fracture.This was noted as the balloon was being withdrawn from the patient via the sheath and only the proximal segment came out.The remaining distal segment was then visualized with fluoroscopy to confirm it¿s presence still in the body and it¿s location.The detached portion does not remain in the patient.Another nc euphorias device (2.0x20mm) was inflated to low pressure was used to trap the fractured catheter inside a 6f non-mdt catheter that was being used during the case.The 6f non-mdt catheter, the fractured balloon catheter and additional balloon were then removed from the body as a single unit with no complications.No patient injury is reported.

Evaluation summary: the device returned with a detachment on the hypotube 48.5cm distal to the strain relief.The hypotube material was oval and jagged on both sides of the detachment site.Kinks were evident on the hypotube 0.5cm , 2.5cm and 14cm proximal to the detachment site.It was not possible to perform inflation testing due to the detachment.There was no stretching to the balloon bonds.There was damage to the guide wire entry port.No other damage visible to the distal shaft.If information is provided in the future, a supplemental report will be issued.
