Event Description
|
It was reported that balloon leak occurred.The target lesion was located in a coronary artery.After pre-dilatation was performed, a 20 x 3.00 rebel stent was advanced to treat the lesion.However, after the device was positioned in the right location, negative pressure was applied and backflow of blood was noted in the inflation device from the inflation port.The device was completely removed from the patient's body and the procedure was completed with another 20 x 3.00 rebel stent.No patient complications were reported and the patient's status was fine.According to the physician, the actual balloon looked like it was already broken inside the system.

Manufacturer Narrative

Device evaluated by mfr., eval summary attached, method codes, result codes, conclusion codes updated.Device evaluated by mfr: returned product consisted of a rebel stent delivery system (sds) with stent.The stent, balloon, shaft, tip and markerbands were microscopically examined.There was blood in the hub, and inflation lumen.The balloon was tightly folded with the stent secure between the markerbands.There were numerous kinks throughout the hypotube.The proximal end of the stent was damaged with a strut bent/flared.The end of the core wire was protruding out of the outer shaft.Engineering lightly stretched the outer shaft causing the core wire to recess back within the outer shaft.Functional testing was performed by attaching an inflation device filled with water to the device.When positive pressure was applied, a stream of water emitted from the hole in the shaft causing the device not to inflate.Inspection of the remainder of the device revealed no other damage or irregularities.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 most probable root cause is operational context as device performance was limited due to anatomical/procedural factors.(b)(4).
