According to the reporter, during balloon inflation inside the patient¿s vein, the physician felt adequate pressure was applied to open the vessel, and it was not until they deflated the balloon that they noticed blood infiltration.Upon further investigation, it was found that the proximal end of the balloon leaked where it was attached to the shaft closest to the exit port causing pressure in the balloon to not be sustained and had leakage of contrast.It was stated that there was no burst occurred, just a subtle leak detected by infiltration of blood while in vessel.No defects/damages found on the product where the leak was observed (crack, cut, etc.).There were 3-4 inflations (in total) applied to the device prior to the issue occurring.Also, prior to use, it was observed that the hooked pin in the distal tip of the balloon catheter was very difficult to remove but it was removed as normal by pulling it out using their fingers, but it required more force than normal.Tego was not utilized.There was no luer adapter issue.Chg (chlorhexidine gluconate) wash the cleaning agent used on the insertion site prior to product placement.A sheath was in place as normal but the leak did not occur at site of insertion.A 3ml luer lock syringe (hand syringe) filled with 50/50 contrast and saline (inflation fluid) was being utilized with the device and balloon was said to be inflated by syringe.Aside from saline, there was no other cleaning agent used on the device.Introducer sheath was also used; sheath french size and brand were 6fr.Merit and the make and size of guidewire were angled glide,.035.The device did not pass through a previously deployed stent.No resistance encountered when advancing the device.No excessive force used during delivery and during withdrawal.The device was flushed per ifu (instruction for use) with no issues identified.It was said that there was just a minuscule amount of blood loss and no blood transfusion was required.No medical intervention/treatment provided due to the event.Catheter was not repaired as nothing could be done to repair it.Also, they did not pull out another catheter as the physician determined that the balloon have held sufficient pressure to open the vessel, and therefore further intervention was not required.Balloon leak did not also affect the case or outcome as it was very small so the procedure was still completed.There was no reported patient injury.
