Cerebral vasculature stent

摘要

An improved expandable stent for implantation in a body lumen, such as an artery and in particular for use in neurovasculature. The stent (10) consists of a plurality of radially expandable cut cylindrical elements (12) or rings generally aligned on a common axis and interconnected by one or more interconnective elements (13), in a manner to optimize flexibility and to achieve desired transitions in flexibility. The individual radially expandable circumferentially extending elements (12) are disposed in an undulating pattern and the overall stent pattern provides a structure that is visible by such methods as fluoroscopy.
