The 5f 5mm x 4mm x 40cm powerflex p3 percutaneous transluminal angioplasty (pta) dilatation catheter was inflated in the anatomic part with stenosis; however, it ruptured within its nominal pressure.
This was a shunt percutaneous transluminal angioplasty (pta) case and was completed using a new non-cordis balloon catheter.
There was no reported patient injury.
The intended procedure was anastomotic stenosis which has severe acute angulation.
The lesion had ninety nine percent of stenosis and no calcification.
The device was stored, handled and prepped per the instructions for use (ifu).
There was no difficulty removing the product from the hoop, the protective balloon cover, the stylet or any of the sterile packaging components.
There were no kinks or other damages noted prior to inserting the product into the patient.
The catheter was passed with finger support from the body surface.
The contrast to saline ratio was 1:1.
A cordis indeflator was used successfully with other devices.
There was no resistance/friction while inserting the balloon through the rotating hemostatic valve or through the guide catheter.
There was no difficulty advancing the balloon catheter through the vessel.
The product was removed intact (in one piece) from the patient.
The device was not returned for analysis as it was discarded.
A product history record (phr) review of lot 82160256 revealed no anomalies or non-conformances during the manufacturing and inspection processes that can be associated with the reported event.
The reported ¿balloon burst-at/below rbp¿ could not be confirmed as the device was not returned for analysis.
The exact cause could not be determined.
The procedure performed was a shunt percutaneous transluminal angioplasty (pta) case.
Arteriovenous shunts are often scarred and fibrous in nature and therefore often resistant to balloon expansion increasing the likelihood of damage to the balloon.
However, without the return of the device for analysis it is difficult to draw a clinical conclusion between the device and the event reported.
According to the instructions for use ¿if resistance is met during manipulation, determine the cause of the resistance before proceeding.
Balloon pressure should not exceed the rated burst pressure.
The rated burst pressure is based on the results of in vitro testing.
At least 99.
9% of the balloons (with a 95% confidence), will not burst at or below their rated burst pressure.
Use of a pressure monitoring device is recommended to prevent over pressurization.
Use only the recommended balloon inflation medium.
Never use air or any gaseous medium to inflate the balloon.
¿ neither the phr nor the information available suggests a design or manufacturing related cause for the reported event.
Therefore, no corrective or preventive action will be taken at this time.
