ABSTRACT:
A method for making an implantable stent includes the steps of (i) providing a plurality of elongate stent wires; (ii) forming said wires into a hollow tubular structure having opposed first and second open ends; (iii) terminating said wires at the second end; (iv) aligning the wires at the second end into a plurality of mated adjacent wires to define a plurality of abutting regions; (v) welding the mated adjacent wires to one and the other at the abutting regions to define a plurality of welds; and optionally (vi) chemically or electro-chemically removing a portion of the welds. The method may further include the steps of (a) extending at least one of the mated stent wires to provide an extended stent wire; (b) looping the extended stent wire so the extended end abuts a proximal pair of stent wires; and (c) welding the extended and looped wire to the proximal pair of wires. The step of looping may include the forming of the wire into an equilaterally arched loop having an apex, but not having other sharp bends.
