ABSTRACT:
A stent in the form of a generally tubular member has a diameter allowing for insertion into a body passageway and is radially expandable upon application of an outward force. A series of annular units are axially arranged to construct the stent. Each annular unit includes a plurality of generally ellipsoidal or polygonal elements equiangularly arranged around the stent axis, the elements being axially elongate and having a center opening. A tie member connects opposed ends of adjacent elements. Adjacent annular units are interconnected at their tie members by a connecting member.
