Manufacturer Narrative

The device was received at boston scientific for analysis.Visual inspection noted no abnormalities.Functional tests were performed, and the sheath failed standard manufacturing testing when air was observed in the flush line during the aspiration test.The sheath passed the hemostasis valve test which was released without a dilator inserted during the test.The sheath was able to maintain the appropriate pressure.An air pressure test was performed to find the location of leaks.The sheath handle was disassembled to find the area where the leak occurred, and no leak was found.The reported field observation was confirmed through cis analysis.Boston scientific manufacturing processes include extensive inspections to ensure that all finished devices meet specifications.To reduce the potential for air ingress into the sheath and the risk of embolism, the polarsheath instructions for use (ifu) was revised to emphasize best practices during use of this device.On april 13, 2021, boston scientific issued a field safety notice (92688876-fa) to communicate these ifu updates to all global customers in the interest of minimizing the risk of air embolism and promoting consistent use of the ifu in all geographies.
