Abstract
The present embodiments provide a method for delivering a stent comprising providing a stent in a delivery state, where the stent comprises a plurality of interconnected strut segments that enable expansion of the stent from a delivery state to a deployed state. Stacking a frontal surface of a first strut segment at least partially behind a rear surface of a second strut segment in the delivery state. Aligning a sharpened tip of a first barb at least partially circumferentially behind at least one strut segment in the delivery state such that the sharpened tip is not radially exposed. Expanding the stent from the delivery state to a deployed state, wherein the first barb is exposed to a patient in the deployed state.

A method for delivering a stent, comprising:
- providing a stent in a delivery state, wherein the stent comprises a plurality of interconnected strut segments that enable expansion of the stent from the delivery state to a deployed state;
- stacking a frontal surface of a first strut segment at least partially behind a rear surface of a second strut segment in the delivery state;
- aligning a sharpened tip of a first barb at least partially circumferentially behind at least one strut segment in the delivery state such that the sharpened tip is not radially exposed;
- and
- expanding the stent from the delivery state to a deployed state, wherein the first barb is exposed to a patient in the deployed state.
A method for delivering a stent, comprising:
- providing a stent in a delivery state, wherein the stent comprises a plurality of interconnected strut segments that enable expansion of the stent from a delivery state to a deployed state;
- positioning a first barb at least partially laterally between first and second strut segments in the deployed state;
- and
- positioning the first barb at least partially on an opposing side of the second strut segment in the delivery state.
A method for delivering a stent, comprising:
- delivering a stent in a delivery state to a target site, wherein the stent comprises a plurality of interconnected strut segments that enable expansion of the stent from a delivery state to a deployed state;
- expanding the stent from a delivery state to a deployed state, wherein a first barb moves to a position at least partially between first and second strut segments in the deployed state, from a position at least partially on an opposing side of the second strut segment in the delivery state.
