Abstract
The present invention is an improved endovascular device particularly useful for use in transjugular intrahepatic portosystemic shunt (TIPS) procedures. The device employs a two-part stent-graft construction that provides a low permeability membrane to line the shunt and an uncovered stent portion designed to reside in the portal vein. The device provides numerous benefits over previous stents and stent-grafts used in TIPS procedures, including being more compact to deliver, being easier to accurately deploy, a controlled compacted surface with tucked apices, an improved stent winding pattern, and being more flexible in delivery and use.
