Age at time of event: 18 years or older (b)(4).
Device evaluated by mfr: returned product consisted of a quantum maverick balloon catheter.
The balloon was loosely folded.
There was contrast in the inflation lumen.
There was blood in between balloon folds.
The outer shaft, inner shaft, balloon and tip were microscopically examined.
The hypotube shaft was completely separated 56.
5 cm from the tip.
The fracture faces were oval as if kinked prior to separation.
There were numerous hypotube kinks.
There was tip damage.
There was no evidence of any material or manufacturing deficiencies contributing to the damage.
The manufacturing batch record review confirmed that the device met all material, assembly and performance specifications.
The most probable root cause is operational context as device performance was limited due to anatomical procedural factors.

Reportable based on device analysis completed on 08-feb-2017.
It was reported that shaft kink occurred.
The target lesion was located in a coronary artery.
A 3.
25mm x 12mm quantum¿ maverick¿ balloon catheter was advanced for dilation.
However, it was noted that the shaft was kinked.
The procedure was completed with another of the same device.
No patient complications were reported and the patient's status was stable.
However, returned device analysis revealed hypotube break.
