Abstract
Described here are methods for forming one or more tracts in tissue. The tracts may be formed in any suitable or desirable tissue, and may seal relatively quickly without the need for a supplemental closure device. In some variations, the methods comprise advancing a tissue-locating member adjacent to a tissue wall, deforming at least a portion of the tissue wall with the tissue-locating member, and advancing a tissue-piercing member through the deformed tissue to form the tract, where the tract provides access for one or more tools. Also described here are methods of forming tracts through rotated or tented tissue. Any of the methods described here may also be used with tissue having at least one irregular surface.
