Event Description
|
It was reported that the blade lifted.
The 90% stenosed target lesion was located in the moderately tortuous forearm shunt.
A 6.
00mm/50cm 2cm peripheral cutting balloon was selected for use.
During procedure, severe resistance was noted upon removing the device from the sheath after dilation.
However, it was noted that the blade of the cutting balloon got lifted about 3mm on the proximal side.
The procedure was completed with the device.
No patient complications were reported.

It was reported that the blade lifted.
The 90% stenosed target lesion was located in the moderately tortuous forearm shunt.
A 6.
00mm/50cm 2cm peripheral cutting balloon was selected for use.
During procedure, severe resistance was noted upon removing the device from the sheath after dilation.
However, it was noted that the blade of the cutting balloon got lifted about 3mm on the proximal side.
The procedure was completed with the device.
No patient complications were reported.
The device was returned for analysis.
A visual and microscopic examination was performed on the returned device.
It was noted that a section of one of the blades approximately 6mm in length was partially detached from the proximal end of the balloon material.
The remaining section of blade and measuring approximately 14mm in length and the entire blade pad remained undamaged and fully bonded to the balloon material.
The entire 2cm of blade was accounted for.
All other blades were intact and fully bonded to the balloon material.
A visual examination identified that the balloon was not folded which indicates that the balloon was subjected to positive pressure.
Blood was identified within the balloon and inflation lumen which is evidence of a device leak.
The returned device was attached to an encore inflation unit.
Positive pressure was applied when liquid was observed to be leaking from a balloon pinhole located approximately 11mm proximal of the distal markerband.
An examination of the balloon material and markerband identified no issues which could potentially have contributed to this complaint.
No issue was observed with the tip or markerbands of the device which could have contributed to the complaint incident.
A visual and tactile examination identified that the shaft was kinked at the distal edge of the strain relief.
No other issues were identified during the product analysis.
