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.

Claims

1. A device for forming a tract in tissue comprising:

an elongate member;

a suction member coupled to a distal portion of the elongate member, the suction member defining a basal surface and an underside surface, the underside surface configured to support an adjacent tissue portion as the adjacent tissue portion is drawn against the underside surface by a suction load which may be applied to the suction member; and

a tissue-piercing member slidably housed within the elongate member and configured to create a tract in across the adjacent tissue portion to accommodate passage of one or more tools for conducting a procedure through the tract, wherein the tissue-piercing member is configured to be advanced across at least a portion of the adjacent tissue portion such that the tract created is a self-sealing tract that generally seals without supplemental closure devices after the one or more tools have been withdrawn from the tract.

2. The device of claim 1, wherein the elongate member is flexible.

3. The device of claim 1, wherein the suction member is coupled to the elongate member via a flexible portion.

4. The device of claim 3, wherein the flexible portion is a hinge.

5. The device of claim 1, wherein the elongate member is articulatable.

6. The device of claim 1, wherein the tissue-piercing member is articulatable.

7. The device of claim 1, wherein the suction member is articulatable.

8. The device of claim 1, wherein the suction member has one or more tissue apposition members thereon.

9. The device of claim 8, wherein the tissue apposition member is a rib.

10. The device of claim 1, further comprising one or more sensors.

11. The device of claim 1, wherein the tissue-piercing member is a needle.

12. The device of claim 11, wherein the needle is hollow.

13. The device of claim 1, wherein the suction member is connected to a vacuum source.

14. The device of claim 1, wherein the elongate member has one or more lumens therethrough.
