Abstract:

An endoprosthesis configured to shift between a collapsed configuration and an expanded configuration may include a tubular scaffold formed from a single filament knitted about a central longitudinal axis and defining a length from a proximal end to a distal end, the tubular scaffold including a plurality of rows of loops and a plurality of rows of rungs arranged around the central longitudinal axis in an alternating fashion; and a polymeric covering extending along the tubular scaffold. Each row of loops and each row of rungs extends longitudinally along the tubular scaffold between the proximal end and the distal end. The tubular scaffold includes a first cutout region extending along a majority of the length of the tubular scaffold and a second cutout region extending along a majority of the length of the tubular scaffold. The polymeric covering is uninterrupted along the first cutout region and the second cutout region.
