WallFlex™ Biliary Transhepatic Stent System


The most frequently implanted biliary metal stent throughout the U.S., Canada and Europe – is available with a transhepatic delivery system designed specifically to meet the needs of IRs. This third generation stent platform from BSC was built on clinical evidence and industry-leading innovation and is available in fully covered, partially covered and uncovered options for the palliative treatment of biliary strictures produced by malignant neoplasms. The fully covered stent is also approved for the treatment of benign biliary strictures.
