Manufacturer Narrative

The reported event of balloon could not maintain its inflation was not confirmed.However, visual examination found three cracks at catheter tip.Crack 1 located outer surface of tip was less than 0.5 mm long, crack 2 and 3 could not be measured because they were inside of the lumen.It was unable to determine if edges of cracks matched up.The balloon was inflated with 1.7 ml air and 0.9 ml water as recommended in japanese product ifu.The balloon inflated clear and concentric and remained inflated for 5 min.Without leakage.No visible damages were observed from the balloon and windings.The through lumen was found to be patent and did not leak.Further evaluation regarding supplier related quality issues is under investigation.A device history record review was completed and concluded a non conformance report was found.Complaint histories for all reported events are reviewed against trending control limits on a monthly basis and any excursions above the control limits are assessed and documented as a part of the monthly review.

Manufacturer Narrative
|
An engineering evaluation was initiated to assess for any manufacturing-related processes which could be correlated to the complaint.Based on the investigation, the most probable root cause for the high incidence of crack defects in the catheter tip area is associated to the units handling when inserting and removing the mandrel during the manufacturing process.In addition, an opportunity was identified to align the instructions of the tip inspection in the different procedures used in the operations where the tip area is inspected.A capa was generated to address the issue.Complaint histories for all reported events are reviewed against trending control limits, and any excursions above the control limits are assessed and documented as part of this monthly review.
