An angioplasty stent comprises a body comprising a plurality of successive segments connected in pairs by bridge means so that the successive segments can be oriented relative to one another for the purposes of bending of the body in any direction defined by a linear combination of respective orientation axes defined by the bridge connection means. During the radial expansion of the stent, the axial contraction of the segments resulting from the opening-out of the respective loops is compensated by axial projection of the bridge elements from the respective concave portions. The wall of the body comprises arms for supporting a lumen as well as regions which are selectively deformable during the expansion of the stent, the arms and the selectively deformable regions having different cross-sections and/or cross-sectional areas. At least one portion of the body may have a substantially reticular structure, the branches of which define geometrical figures identifiable as fractals.
A stent for supporting the wall of a vessel, the stent having a tubular body capable of being expanded from a radially contracted position to a radially expanded position, the stent comprising:
A stent for supporting the wall of a vessel comprising a tubular body capable of being expanded from a radially contracted position to a radially expanded position, the tubular body including a plurality of annular segments, each annular segment connected to at least one other annular segment by at least two bridge connectors, the plurality of annular segments including first and second annular segments having a wave shape, the first and second annular segments being connected by first and second bridge connectors, the first and second bridge connectors having a shape defining a sinusoidal path of greater than 360° from the first annular segment to the second annular segment.
A method of making a stent for supporting a vessel wall comprising:
A stent for supporting the wall of a vessel comprising a tubular body capable of being expanded from a radially contracted position to a radially expanded position, the tubular body including a plurality of annular segments, each annular segment connected to at least one other annular segment by at least two bridge connectors, the plurality of annular segments including first and second annular segments having a shape defining a sinusoidal path which includes a plurality of alternating peaks connected by a plurality of arm sections, the first and second annular segments being connected by first and second bridge connectors, the first and second bridge connectors defining a sinusoidal path of approximately 720° from the first annular segment to the second annular segment, the first bridge connector being connected between a first peak of the first annular segment and a first peak of the second annular segment and the second bridge connector being connected between a second peak of the first annular segment and a second peak of the second annular segment.
A stent for supporting the wall of a vessel, the stent having a tubular body capable of being expanded from a radially contracted position to a radially expanded position, the stent comprising:
