Stent
First Claim
1. A stent in the form of a substantially tubular body, comprising:
- multiple serpentine, annularly expandable elements, said serpentine elements having first and second ends facing in an axial direction of the stent, said first and second ends having arcs; and
Y-shaped connectors connecting at least three axially adjacent ones of the serpentine elements, each of said connectors having a single base arm and two fork arms having a forking point exclusively connected to the single base arm, said single base arm being connected to one of the arcs of the second end of one of the adjacent serpentine elements, said two fork arms being connected to two neighboring ones of the arcs of the first end of another one of the adjacent serpentine elements in one to one correspondence,wherein in a non-expanded state of the stent the connectors extend in a circumferential direction of the stent and have a curvature in the circumferential direction, said curvature in an expanded state of the stent having a size in the circumferential direction so that at least a portion of the base arm and a portion of the fork arms of the connectors protrude radially outwardly over a circumference of each of the serpentine elements.

Abstract
A stent in the form of a generally tubular body has multiple annularly expandable serpentine elements. The serpentine elements have arcs at the first and second element ends which point in the axial direction of the stent. Annularly expandable serpentine elements which follow one another in the axial direction are connected to one another via connectors which are arranged at the ends of the adjacent elements. The connectors extend in the circumferential direction of the stent in the non-expanded state of the stent and have a curvature in the circumferential direction. In the expanded state of the stent, the curvature is so great in the circumferential direction that the connectors project radially outward beyond the circumference of the serpentine elements.
