Welded sinusoidal wave stent
First Claim
1. A medical device for use in supporting a luminal surface of a human or animal body comprising a malleable or resilient wire having a proximal end, a distal end, and a preformed series of peaks alternating with valleys;
- each peak and contiguous valley constituting a wave;
the device being formed in a hollow cylindrical shape comprising a plurality of circumferential revolutions of the wire and having a number of waves per circumferential revolution;
wherein a first wave of a circumferential revolution having an off-peak point aligns to a second wave of an adjoining circumferential revolution having an off-valley point and wherein the first and second waves of at least one pair so aligned are affixed to each other at a contact point comprising the off-peak point of the first wave and the off-valley point of the second wave.

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.
