Abstract
Described here are methods and devices for forming tracts in tissue. Some of the devices feature an elongate member, a suction member coupled to a distal portion of the elongate member, and a tissue-piercing member slidably housed within the elongate member for forming a tract in tissue. Other devices feature more than one suction member. Methods for forming tracts in tissue are also described here. In some methods, a device is advanced adjacent tissue, where the device features one or more suction members and a tissue-piercing member. Suction is applied so that the tissue is drawn against the one or more suction members, and a tissue-piercing member is advanced in a first direction through the drawn tissue to form a tract in or through the tissue. Kits incorporating one or more of the devices described here, in conjunction with one or more tools or the like, are also described here.
