Abstract

As described herein vascular anchoring systems are used to position an implant in a vascular area such as a bifurcated vasculature with relatively high fluid flow, for instance, in an area of a pulmonary artery with associated left and right pulmonary arteries. Implementations include an anchoring trunk member having a first anchoring trunk section and a second anchoring trunk section. Further implementations include a first anchoring branch member extending from the anchoring trunk member. Still further implementations include a second anchoring branch member extending from the anchoring trunk member.
