摘要： An illustrative stent may comprise an elongated tubular member having a first end and a second end and an intermediate region disposed therebetween. The elongated tubular member configured to move between a collapsed configuration and an expanded configuration. The elongated tubular member may comprise at least one twisted filament, such as a knitted filament having a plurality of twisted knit stitches with intermediate rung portions extending between adjacent twisted knit stitches, or a plurality of helical filaments twisted with a plurality of longitudinal filaments.

摘要： The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to delivery systems configured to position a distal portion of a medical device within a restricted anatomical area. In one example, a delivery system may include a flexible elongate member with an inner member within a lumen of the flexible elongate member. A stent may be constrained therebetween. The stent may be configured to move between a first configuration to a second deployed configuration when unconstrained from the flexible elongate member. When the stent moves from the first configuration to the second configuration, the inner member may change from a first length to a second, shorter length. Other embodiments are contemplated.
