STENTS HAVING BARBS PROTECTED DURING DELIVERY |
| 摘要 |
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. |

1. 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. |
