摘要：
Tissue tract-forming devices, methods, and kits are disclosed. In some variations, a method for forming a tract in a tissue wall having an interior surface and an exterior surface may comprise advancing an anchor member through the tissue wall and into a lumen defined by the tissue wall, the anchor member comprising a proximal portion, a distal portion, and an intermediate portion therebetween, wherein the proximal and intermediate portions are angled with respect to each other and the intermediate and distal portions are angled with respect to each other, positioning the anchor member so that the intermediate portion contacts the interior surface of the tissue wall and the distal portion is angled toward the interior surface of the tissue wall, and advancing a tissue-piercing member into the tissue wall while the intermediate portion is in contact with the interior surface of the tissue wall, to form a tract.
