Abstract

Pushing a self-expanding stent from one of its ends, during release of the stent at a stenting site in a bodily lumen, by proximal withdrawal of a surrounding sheath, can impose unacceptably high stresses on parts of the strut network of the stent. For location of stents in a bodily lumen, it is customary to equip the end annulus of a stent with radiopaque markers. The present invention involves arranging the markers so that they share with non-marker portions of the end annulus the stresses imposed in the stent by the end pushing, whereby the high stresses are shared more equally by all the struts of the stent in the end annulus.
