Abstract
Example embodiments include an endoprosthesis that has a first annular segment that is radially expandable and a second annular segment that is also radially expandable. An axial segment, which includes one or more struts, is operatively associated with the first annular segment and the second annular segment to maintain a specified distance between the first annular segment and the second annular segment.
Claims22
An endoprosthesis that is radially expandable, comprising:
- a first portion including an annular segment that is orientated about a central axis;
- and
- a second portion coupled to the first portion and including one or more axial segments extending along the central axis.
An endoprosthesis comprising:
- a first annular portion oriented about a central axis;
- a second annular portion oriented about the central axis;
- and
- a connection portion including one or more axial segments with a first end and a second end, the first end being connected to the first annular portion, the second end being connected to the second annular portion.

An endoprosthesis comprising:
- a first column segment including a first proximal end, a first distal end, and a first plurality of undulating column struts that extend from the first proximal end toward the first distal end of the first column segment;
- a second column segment including a second proximal end, a second distal end, and a second plurality of undulating column struts that extend from the second proximal end toward the second distal end of the second column segment;
- and
- a column interface that couples the first column segment to the second column segment.
