DEVICE SYSTEM AND METHOD FOR RESHAPING TISSUE OPENINGS
First Claim
1. A device for resizing/reshaping a tissue opening comprising a cage structure being positionable within the tissue opening and being radially expandable therein via inflation of at least one balloon positioned within said cage structure, wherein the device enables flow of a biological fluid through the tissue opening when said at least one balloon is fully inflated and said cage structure is fully expanded and biased against a tissue defining the tissue opening.

21. A method of resizing/reshaping a tissue opening comprising:
-
(a) positioning a cage structure within said tissue opening; (b) expanding said cage structure within the tissue opening thereby biasing outward tissue defining the tissue opening while enabling biological fluid to flow through the tissue opening, thereby resizing/reshaping the tissue opening; and (c) controlling said flow through said cage structure. - View Dependent Claims (25, 26)
