ABSTRACT:
A medical device for use in the interior of a body lumen including a catheter and a radially expandable stent mounted on the catheter. The radially expandable stent is in the form of a hollow cylinder defined by a sequence of spaced apart wire elements with each of the wire elements extending 360 degrees around the cylinder and the wire elements having extendible, sinusoidal zig-zags lying flat with respect to the cylinder. The zig-zags are shaped in a generally longitudinal direction along the cylinder at one point and then reverse their direction so that the zig-zags may open as the wire element is expanded. The adjacent wire elements are flexibly connected together in an end-to-end fashion by helical winding.
