<p>A stent (10) includes a cylindrical frame (11) and a plurality of connecting segments (13) connecting opposed portions of the frame. The frame may be formed from either of a single loop of resilient wire formed into a series of arcuate sections (12) and longitudinal connecting sections, two pieces of resilient wire each formed into a half-frame having a series of arcuate sections and longitudinal connecting sections or from a piece of laser cut hypotubing. For the resilient wire frames, the connecting segments may be either of a single metal or plastic band wrapped around opposed longitudinal sections, joined individual bands wrapped around opposed longitudinal sections, or a piece of solder joining opposed longitudinal sections. For the hypotubing frame, the connecting segments are pieces of remaining hypotubing joining opposed longitudinal sections.</p> |
