After further review of additional information received the following sections have been updated accordingly: b5, d4, g3, h1, h2, h3 and h6 as reported, an 8mm 4cm saberx radianz unit failed in the cordis r&d lab in miami lakes.No patients or other institutions were involved.During inflation testing the product exhibited a pinhole failure at the proximal end of the balloon.The device was not returned, only an image was provided.One picture related to the reported failure was attached to the complaint.The image shows the distal section of the catheter.When pressurized, a leakage in the balloon is observed.No other anomalies of the product are noted in the attached picture.A product history record (phr) review of lot 82246656 revealed no anomalies or non-conformances during the manufacturing and inspection processes that can be associated with the reported event.The reported ¿balloon leakage - during positive pressure¿ was confirmed via picture analysis as a leakage of water was noted in the images provided.However, the exact cause cannot be determined.This device was not in a clinical setting, this was noted during testing at a cordis facility.Therefore, it is likely handling of the device and environmental factors may have contributed to the failure noted.According to the warnings in the safety information in the instructions for use, ¿without twisting, slide the forming tube off the balloon.Attach a syringe filled with sterile heparinized saline or similar isotonic solution to the flushing needle.Remove the protection sheath from the flushing needle, insert the needle into the tip of the catheter and flush the guidewire lumen.Attach a 3-way stopcock to the inflation port, which is marked ¿balloon¿.Attach a partially filled syringe with heparinized saline to the stopcock, open the stopcock to the balloon and induce negative pressure.Hold the syringe and proximal end of the catheter above the distal end of the catheter and hold the balloon vertically with the balloon tip pointing down.While maintaining negative pressure close the stopcock to the inflation port.Remove the syringe and purge the air.To ensure air contained in the balloon and inflation lumen is removed, apply negative pressure twice as instructed and repeat steps 4 - 6.Prepare an angioplasty inflation system with a 50% solution of contrast medium in sterile saline or similar solution.Purge the air from the inflation device.Connect the inflation device to the 3-way stopcock that is connected to the catheter inflation port, open the stopcock to the catheter and slowly fill the inflation lumen and the balloon will slowly fill with diluted contrast medium.Caution: do not apply positive or negative pressure to the balloon at this time.¿ 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.
