Abstract
A stent shaped as a three-dimensional body which is formed by interlaced threads (1) arranged in multistart turns of a helical line. The threads (1) are arranged in at least two groups (2 and 3) of the helical turns featuring opposite senses of helix. The stent ends are established by sections (5) where the turns of one helical line merge into those of the other helical line, said sections appearing as a single length of the thread (1).
Claims47
An implantable endoprosthetic device shaped as a three-dimensional body whose surface is formed by at least two groups of turns made of interlaced threads and arranged along helical lines having opposite senses of helix, and at least one end face of said three-dimensional body is formed by sections where the turns of one helical line pass into the turns of the other helical line to define bending points;
- wherein portions of said threads cross to define an interlacing pattern, said crossing portions being configured to slide with respect to one another.
An implantable endoprosthetic device shaped as a three-dimensional body having first and second ends and a side surface disposed between the first and second ends, the side surface being formed by two groups of elongated elements, each of the elongated elements being formed from an thread extending in a helical configuration along a longitudinal axis of the said body, the elements of the first group having a common first direction of winding and the elements of the second group having a common second direction of winding opposite to the first direction;
- wherein the elements of the first group are interlaced with elements of the second group;
- and
- wherein at least one end of said first or said second end of said three-dimensional body is formed by at least one section where the first direction of winding of at least one element of the first group passes into the second direction of winding of at least one element of the second group to define a bending point thereat.
An implantable endoprosthetic device for placement within a body lumen, comprising:
- a body having first and second ends;
- at least two elongate elements defining said body, said elongate elements configured to provide said body with an interlacing pattern;
- wherein portions of said elongate elements cross to define said interlacing pattern, said crossing portions being configured to slide with respect to one another;
- and
- wherein at least one of said first or said second ends of said body is formed by turns of said elongate elements to define bending points thereat.
