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 .
