Stent having less invasive ends

摘要

The present examples provide a stent for use in a medical procedure that comprises at least one apex having first and second generally straight portions and a curved portion disposed between the first and second straight portions. The curved portion may comprise at least one region having a cross-sectional area that is less than a cross-sectional area of the first and second straight portions, which may facilitate compression of the stent and insertion of the stent into smaller vessels. The stent may be used alone, or in conjunction with a stent-graft, and may comprise one or more barbs configured to engage an inner wall of a vessel or duct.

1. A stent for use in a medical procedure, the stent comprising:
at least one apex comprising a strut having first and second generally straight portions and a curved portion disposed between the first and second generally straight portions, where the curved portion comprises at least one region having a cross-sectional area that is less than a respective cross-sectional area of each of the first and second generally straight portions, where the cross-sectional area of the curved portion is measured as being perpendicular to the strut at the at least one region of the curved portion, where the respective cross-sectional area of each of the first and second generally straight portions is measured as being perpendicular to the strut at the respective one of the first and second generally straight portions, and where the first and second generally straight portions each have a respective portion aligned with a longitudinal axis of the stent in an expanded state.
