Abstract
A wire stent having a preformed series of peaks alternating with valleys. The wire is formed from a malleable or resilient material and can be wound into a continuous helix. Each pair of peaks and valleys constitutes a wave. The stent has a number of waves per circumferential revolution such that the adjoining waves align off-peak to off-valley with one or more such adjoining waves being affixed to each other at the off-peak to off-valley locations. The waves can be welded at all locations or only at the circumferential revolutions at the proximal and distal ends of the stent, or intermittently, or in barber pole fashion or along one or more longitudinal axes.
