Abstract
A prosthesis can be configured to be deployed within a body cavity. The prosthesis has an expandable frame, a plurality of proximal anchors, and a plurality of distal anchors, where the various anchors are connected to the frame. Radial expansion of the frame can cause the ends of the proximal anchors and the ends of the distal anchors to draw closer together.

21. A prosthesis configured to grasp intralumenal tissue when deployed within a body cavity, the prosthesis comprising:
-
an expandable frame comprising a proximal end and a distal end and a longitudinal axis extending therethrough, the frame configured to radially expand and contract for deployment within the body cavity; a plurality of proximal anchors each connected to the frame so that when the frame is in an expanded configuration an end of each proximal anchor is positioned radially outward from the frame and extends generally distally; and a plurality of distal anchors each connected to the frame so that when the frame is in an expanded configuration an end of each distal anchor is positioned radially outward from the frame and extends generally proximally, wherein the ends of the distal anchors are axially spaced from the ends of the proximal anchors when the frame is in an expanded configuration; wherein at least some of the anchors comprise a looped anchor comprising a first segment and a second segment extending radially outward from the frame in a direction generally toward one end of the frame, the first and second segments joining to form a loop at a location radially outward from the frame; and wherein the frame is configured such that radial expansion of the frame causes the ends of the proximal anchors and the ends of the distal anchors to draw closer together. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
