Abstract
The present disclosure provides a modular stent assembly for deployment within a lumen. The assembly may include primary and secondary stent portions. Each stent portion includes a sheet having an incomplete annular profile. The sheet includes a graft material disposed on a wire matrix. Each stent portion further includes an aperture positioned in the sheet, and first and second side walls. The first side wall extends between the aperture and a first longitudinal edge of the sheet. The second side wall extends between the aperture and a second longitudinal edge of the sheet, which is spaced apart from the first edge. The stent portions mate to define an interior space in which is positioned an expandable securement stent. An outer wall of the securement stent is sized to compress the side walls of the stent portions between the body of the securement stent and a wall defining the lumen.
