Methods and apparatus for regulating the flow of matter through body tubing
First Claim
1. A method of implanting and securing a device into a food passageway in a patient, the device including at least one deflectable member, comprising:
- delivering the device into the passageway with the member at least partially deflected to a first geometry; and
releasing the member so that it conforms to a second geometry that is different from the first geometry.

Abstract
A self-retracting body, which may have a bore, may be inserted into a biological passage. A dilating balloon may be used to expand the body toward an inner wall of the passage. The body may include an anchor that may engage the wall. The anchor may include a tip that is within the body before the body expands and extends away from the body during expansion. The body may include an opening that may receive a portion of the wall. The portion may be fixed to the body. The body may retract toward a central portion of the passage after the anchor engages the wall. The wall may be drawn toward the central passage and the diameter of the passage may be reduced. In some embodiments, a liner may be provided for the passage. In some embodiments, a baffle may be provided for the passage.

6. Apparatus for use in pulling in on a wall of a tissue passage comprising:
-
a first structure adapted for disposition in the tissue passage; and
a plurality of metal anchors coupled to the first structure and adapted to penetrate the wall to secure the first structure to the wall, the anchors being further adapted to have a first geometrical shape during delivery into the passage, and a second, different geometrical shape upon deployment into the wall. - View Dependent Claims (7, 8, 9, 10, 11)

12. A method of pulling in on a wall of a tissue passage comprising:
-
delivering into the tissue passage a structure that includes a plurality of resilient anchors, the anchors having a first geometrical shape during the delivering; and
deploying the anchors into the wall to secure the structure to the wall, the anchors changing to a second, different geometrical shape during the deploying. - View Dependent Claims (13, 14, 15)
