摘要： A one-piece expandable flat bearing structure formed by at least partially elastically deformable struts which are separated from each other by openings in the bearing structure. The bearing structure can assume at least one compressed condition and at least one expanded condition and has at least one expansion direction. The bearing structure has anchor regions, from which spring struts, which are elastically resilient with respect to the anchor regions, extend to a resiliently deflectable end of the spring struts, a hinge strut adjoining said end. The spring struts and the hinge struts are of such a configuration and arrangement that both the compressed condition of the bearing structure and also the expanded condition of the bearing structure is stabilized by a spring action emanating from the spring struts.

摘要： Preferred embodiments of an implantable medical device with a high degree of flexibility is shown and described. One aspect includes an implantable stent having an intermediate portion with a helical winding and first and second end portions. The implantable stent further includes a coupling portion with a helical winding, and bridges joining struts of defining the helical windings. The stent also includes a paddle providing a bridge joining the ends or the helical windings. Another aspect relates to a radially self-expansible stent with a plurality of radiopaque markers attached to it. The markers are shaped and located at the stent end such that the compressive stress exerted on the end annulus of the stent during release of the stent is shared between the markers and the inflection zones that do not carry a marker.

摘要： 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.

摘要： A self-expanding stent comprising a series of zig-zag stenting rings (A, B, C, D, E, F, D1, D2) spaced along the axis and with adjacent said rings connected by connecting links (12, 14) spaced around the circumference of the rings, the links (12) between any two axially adjacent rings A, B being circumferentially staggered relative to the links (14) between the rings B and C, each ring being constituted by a succession of alternating struts (18) with points of inflection (16, 16′, 16″) therebetween. The points of inflection at one end of at least one of the rings are staggered in their location along the longitudinal axis whereby, with axial withdrawal of a surrounding sheath at a stenting site, to deploy the self-expanding stent, the individual points of inflection at said one ring end escape from the sheath sequentially, with continued withdrawal of the sheath, rather than simultaneously.

摘要： Stent exhibiting a succession of turns around the axis, adjacent turns being connected by connector portions distributed around the circumference of the prosthesis, each of the turns being made up of struts that extend the length of the turn and are interspersed by inflection zones located at the axial ends of each of the turns. When the prosthesis expands radially, gaps open up between adjacent struts of each of the turns, the inflection zones being distributed regularly around the circumference so that the gaps are substantially the same size as each other around the circumference of the turn, characterised in that at least every second turn exhibits a stagger zone within which the said gap between adjacent said struts is of an individual size different from that common to the other gaps of that second turn.
