    摘要： A stent with a preferably cylindrical circumferential wall (1) designed as an open, lattice-like, expandable supporting structure with a longitudinal axis (L) is provided, said stent comprising - helix webs (2.1, 2.2, 2.3) running around helically in windings (W) about the longitudinal axis (L) with a helical primary form and a meandering secondary form, which forms meander bends (3.1, 3.2) with a direction of curvature alternating in the circumferential direction (U) and also forms sub-webs (4.1, 4.2) connecting the meander bend (3.1, 3.2), and - connection webs (7) bridging the helix webs (2.1, 2.2, 2.3) of two adjacent windings (W) with a primary direction of extension (H) parallel to the longitudinal axis (L), said connection webs being joined at their sub-web-side ends (8) to adjacent sub-webs (4.1) of the respective helix web (2.1, 2.2, 2.3) and having a flat, zigzag-like shape with two end branches (9.1, 9.2) and an intermediate central branch (10), wherein the end branches (9.1, 9.2) each lead via a termination bend (12) at least approximately at right angles into the respective sub-web (4.1) and the comers in the mouth region (M) between the termination bends (12) and the sub-webs (4.1) are provided with a recess (14).

    摘要： A method of forming a stent includes forming a wave form from a formable material. The wave form includes a plurality of substantially straight portions and a plurality of curved portions, each curved portion connecting adjacent substantially straight portions. The method includes wrapping the wave form around a mandrel at an angle to form a helical coil comprising a plurality of turns, connecting a first curved portion of a first turn to an adjacent second curved portion of a second turn at a position along the wave form to define an end of the stent, and removing excess material from an end of the wave form extending past the first curved portion while smoothing the end of the stent.

    摘要： A stent for a vessel implanted in the vessel of the living body including a main body portion of the stent formed into a tube by a yarn formed of a biodegradable polymer exhibiting a shape memory function. The main body portion of the stent is shape-memorized to a size that can be implanted in the vessel. The main body portion of the stent is implanted in the vessel of the living body as it is contracted in diameter by an external force, and is enlarged in diameter by being heated with the temperature of the living body. The main body portion of the stent is formed by winding a yarn formed of a biodegradable polymer in a tube form as the yarn is bent in a zigzag design. The main body portion of the stent is enlarged or contracted in diameter with the bends of the yarn as the displacing portions.
