Abstract
A prosthesis can comprise an expandable frame, a plurality of distal anchors and a plurality of proximal anchors. The anchors can extend outwardly from the frame. The frame can be configured to radially expand and contract for deployment within a body cavity. The frame and anchors can have one of many different shapes and configurations. For example, when the frame is in an expanded configuration, the frame can have a larger cross-sectional dimension in a middle portion of the frame and a smaller cross-sectional dimension in a proximal portion and a distal portion of the frame, wherein the middle portion is between the proximal and distal portions. As another example, the anchors can have looped ends, the entire anchor may loop out from the frame.

32. A prosthesis configured to atraumatically engage intralumenal tissue when deployed within a body cavity, the prosthesis comprising:
-
an expandable frame comprising a proximal end and a distal end and having a longitudinal axis extending between the proximal end and the distal end, the frame configured to radially expand and contract for deployment within the body cavity; and a plurality of distal anchors each connected to the frame at a base and having a looped atraumatic end; wherein when the frame is in an expanded configuration; each of the plurality of distal anchors extends from the base generally distally before extending generally proximally and radially outwardly from the frame; and the looped atraumatic end of each distal anchor is circumferentially aligned with the base where the distal anchor connects to the frame so that the looped atraumatic end and the base are both located within a common plane that is parallel to and intersects the longitudinal axis. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46)

47. A prosthesis configured to atraumatically engage intralumenal tissue when deployed within a body cavity, the prosthesis comprising:
-
an expandable frame comprising a proximal end and a distal end and having a longitudinal axis extending between the proximal end and the distal end, the frame configured to radially expand and contract for deployment within the body cavity; and a plurality of distal anchors each connected to the frame at a base and having a looped atraumatic end, wherein each of the plurality of distal anchors is connected to the frame with a single strut; wherein when the frame is in an expanded configuration each of the plurality of distal anchors extends from the base generally distally before extending generally proximally and radially outwardly from the frame. - View Dependent Claims (48, 49, 50, 51)
