METHODS FOR FORMING TRACTS IN TISSUE
First Claim
1. A method for forming a tract in a tissue comprising:
- 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, wherein the tract provides access for one or more tools.

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.

- 13. The method of clam 2, further comprising deforming at least a portion of the tissue after the tissue-piercing member has been advanced, wherein deforming the tissue comprises changing the orientation of the tissue wall from a second configuration to a third configuration.
- 19. The method of 1, wherein the tract seals after the tissue-piercing member has been withdrawn.
-
22. A method for forming a tract in a tissue having an irregular tissue surface comprising:
-
advancing a tissue-locating member adjacent to a tissue wall; reshaping at least a portion of the tissue wall, wherein the tissue wall has an irregular surface; and advancing a tissue-piercing member through the reshaped tissue to form the tract, wherein the tract provides access for one or more tools.

23. A method for forming a tract in a tented tissue comprising:
-
advancing a tissue-locating member adjacent to a tissue wall; tenting at least a portion of the tissue wall; and advancing a tissue-piercing member through the tented tissue to form the tract, wherein the tenting immobilizes at least a portion of the tissue wall during advancement of the tissue-piercing member therethrough.

-
24. A method for forming a tract in a rotated tissue comprising:
-
advancing a tissue-locating member adjacent to a tissue wall; rotating at least a portion of the tissue wall; and advancing a tissue-piercing member through the rotated tissue to form the tract, wherein the rotating helps to position the tissue-piercing member relative to the tissue wall.
-
-
25. A method for forming a tract in a tissue comprising:
-
advancing a tissue-locating member adjacent to a tissue wall; advancing a tissue-piercing member into the tissue wall in a first direction; deforming at least a portion of the tissue wall; and further advancing the tissue-piercing member in a second direction, wherein the first and second directions are different.
