Manufacturer Narrative
|
The catheter without distal part of the balloon was returned.
The balloon portion was broken at about 1cm from the tip.
The device history records (dhr) of the device concerned was reviewed: the production lot, to which the device concerned belongs, passed all in-process inspections including the shaft-pressurized test and the balloon-wrapping test for every product, and the finished product inspections including the shaft tensile strength test and the repetitive balloon inflation/deflation test on representative samples based on sampling plan.
No nonconformity or abnormality in the manufacturing processes of the device concerned was found.
Probable cause(s) and our comment: the balloon was damaged by the hardened sharp edge of the anastomosis and should have been ruptured when the balloon was inflated.
While removing it from the patient, the bulky portion of the ruptured balloon was caught on the sheath and could not be pulled back any more.
Further attempts to forcibly pull back the device resulted in breakage of the balloon and the tip.

Event Description
|
Ohicho3 is an otw-type pta balloon catheter compatible with 0.
035 inch guidewire.
Ohicho3 has no approval in usa.
However, we intend to report this case as the event occurred on the similar device for "metacross otw" (otw type pta balloon dilatation catheter, 0.
035" guidewire compatible) in us under 510(k)# k152080".
The balloon rupture occurred when the balloon was repeatedly inflated at approximately 22 atm.
When it was pulled out, the tip of the catheter was broken.
The tip of the catheter with distal part of the balloon broke may have remained inside the body because it was not found.
