Up until this point is has been impossible to test efficiently stent for inclusions.""However," he says, "a newly developed inclusion detection test has provided a way to efficiently test every single nitinol stent before implantation. On the basis of this test, a citizen petition was filed with FDA, requesting the test's implementation."
