Tabbed stent with minimum compressed profile
First Claim
1. A structure comprising a stent, said stent comprising:
- a first segment comprising;
a first connected crown having a crown width; and
a first unconnected neighbor crown folded over said first connected crown;
a first tab having a length substantially greater than said crown width comprising;
a first tab end; and
a second tab end, wherein said first connected crown is connected to said first tab between said first tab end and said second tab end wherein said first connected crown is connected to approximately a middle of said first tab between said first tab end and said second tab end.

Abstract
A structure and method associated with a tabbed stent that facilitates folding of its unconnected crowns over the adjacent connected crowns, to thus minimize the stent'"'"'s compressed diameter. The middles of tabs and connected crowns are moved radially inwards with respect to unconnected neighbor crowns such that when in a compressed configuration the unconnected neighbor crowns overlap the connected crowns. The tabs of tabbed stent facilitate folding of the unconnected neighbor crowns over the connected crowns connected to the tabs. In this manner, the compressed profile of the tabbed stent and the crossing profile of the catheter containing the tabbed stent is minimized.

18. A method of loading a stent into a sheath comprising:
-
moving an unconnected crown of a segment closer to a connected crown connected to a tab of said stent; and
moving a middle of said tab and said connected crown radially inwards with respect to said unconnected crown, wherein said unconnected crown overlaps said connected crown. - View Dependent Claims (19, 20, 21, 22)
