Stent, assembled of interconnected ring segments designed in a pattern of curved filaments forming stable but flexible structure

摘要

The tubular stent (1) is made of an endless assembly of ring segments (3) designed in a pattern of curved filaments (4, 5, 6, 13). The segments (3) are joined by specifically shaped elements (9, 10). Each of the joint elements (9, 10) is provided with a u-shaped section (11). The specific arrangement of the pattern results in a self-stabilizing framework (2), stable, but still flexible.
