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