Abstract:
1. A method for manufacturing a stent, the method comprising: forming a first continuous wire into a first circumferential ring having an outer surface facing away from a longitudinal axis and having a sinusoidal shape defined by a plurality of peaks connected to a plurality of valleys by a plurality of segments; forming a second continuous wire into a second circumferential ring having an outer surface facing away from a longitudinal axis and having a sinusoidal shape defined by a plurality of peaks connected to a plurality of valleys by a plurality of segments; deforming a peak of the first ring such that a deformed peak portion is unitary with and flanked by non-deformed peak portions on opposite sides, the deformed peak portion having i) an outer surface recessed below outer surfaces of the flanking non-deformed peak portions, and ii) an extension that protrudes in a longitudinal direction away from the first ring and consists of displaced material of the first continuous wire; and abutting and connecting the extension of the deformed peak portion to a valley of the second ring so as to space the non-deformed peak portions from the valley; wherein said connecting comprises welding.
