Abstract
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.
Claims20
A stent, the stent comprising:
- an elongated tubular member having a longitudinal axis and configured to move between a collapsed configuration and a radially expanded configuration, the elongated tubular member comprising a plurality of rows, wherein each row of the plurality of rows includes a plurality of twisted knit stitches each including a loop with an overlapping base portion and a plurality of rung portions separating adjacent loops;
- wherein at least some loops are connected to the overlapping base portion of a longitudinally adjacent loop;
- and
- wherein one or more of the plurality of rows includes a different number of twisted knit stitches than another one of the plurality of rows.
A stent, the stent comprising:
- an elongated tubular member having a longitudinal axis and configured to move between a collapsed configuration and a radially expanded configuration, the elongated tubular member comprising a plurality of twisted knit stitches each including a loop with an overlapping base portion, wherein at least some loops are connected to the overlapping base portion of a longitudinally adjacent loop;
- and
- wherein the elongated tubular member includes a first portion having a first knit pattern and a second portion having a second knit pattern different from the first knit pattern, wherein the second portion has a lower radial force in the radially expanded configuration than the first portion.
A stent, the stent comprising:
- an elongated tubular member having a longitudinal axis and configured to move between a collapsed configuration and a radially expanded configuration, the elongated tubular member comprising a plurality of twisted knit stitches each including a loop with an overlapping base portion, and a plurality of rung portions separating adjacent loops;
- and
- wherein at least some loops are connected to the overlapping base portion of a longitudinally adjacent loop, and at least some loops are connected to a longitudinally adjacent rung portion.
