摘要:
Stent as a body generally tubular shape with several similar elements to coils (3, 3a), annularly extending, where like elements streamers (3, 3a) have arches (9, 9a, 9b) at their first ends and second (8, 19, 21) pointing in the axial direction of the stent (1), wherein like streamers (3, 3a), annularly extending consecutive to each other in the axial direction elements are connected together by connectors (4, 4a, 4b) which are arranged at the ends (8, 21) of adjacent elements (3, 3a), wherein the stent (1, 1a, 1b) being in an unexpanded state the connectors (4, 4a ) extend in the circumferential direction of the stent (1, 1a, 1b) and have a curvature (K1) in the circumferential direction (U); wherein when the stent (1, 1a, 1b) is in an expanded state, the curvature (K1) in the circumferential direction (U) is so great that the connectors (4, 4a, 4b) protrude radially outwardly above the perimeter of the like elements streamers (3, 3a), wherein the connectors (4) having a pattern "Y", where a key arm (10) of the connector (4) is connected via an arc (9) the end (21) of the first element (3) and each of the two fork arms (11, 12) of the connector (4) as "Y" is connected by one of two arches (9) adjacent the end (8 ) the other element (3).Estent en forma de un cuerpo en forma general tubular con varios elementos similares a serpentinas (3, 3a), anularmente extensibles, en donde los elementos similares a serpentinas (3, 3a) presentan arcos (9, 9a, 9b) en sus extremidades primera y segunda (8, 19, 21) que señalan en la dirección axial del estent (1), en donde elementos similares a serpentinas (3, 3a), anularmente extensibles consecutivos entre sí en dirección axial están conectados entre sí mediante conectores (4, 4a, 4b), que están dispuestos en los extremos (8, 21) de los elementos adyacentes (3, 3a), en donde, estando el estent (1, 1a, 1b) en un estado no expandido los conectores (4, 4a) se extienden en la dirección perimetral del estent (1, 1a, 1b) y tienen una cur
