1. A stent delivery system comprising:

  • a) a first introducer having proximal and distal ends comprising;

    i) a first outer catheter having proximal and distal ends, the first outer catheter comprising;

    A) a first proximal outer catheter having proximal and distal ends and a first proximal outer diameter; and

    B) a first distal outer catheter having proximal and distal ends and a first distal outer diameter;

    wherein the first proximal outer catheter distal end is connected to the first distal outer catheter proximal end;

    wherein the first proximal outer diameter is less than the first distal outer diameter;

    ii) a first inner shaft located coaxially within said first outer catheter, the first inner shaft having proximal and distal ends, a first stent retaining area located on a distal portion of the first inner shaft; and

    b) a second introducer having proximal and distal ends comprising;

    i) a second outer catheter having proximal and distal ends, the second outer catheter comprising;

    A) a second proximal catheter having proximal and distal ends and second proximal outer diameter; and

    B) a second distal catheter having proximal and distal ends and a second distal outer diameter;

    wherein the second proximal outer diameter is less than the second distal outer diameter; and

    wherein the second proximal catheter distal end is connected to the second distal catheter proximal end;

    ii) a second inner shaft located coaxially within said second outer catheter, the second shaft having proximal and distal ends, a second stent retaining area located on-a distal portion of the second inner shaft;

    wherein the stent delivery system includes an endoscope comprising a working channel having an inner diameter; and

    wherein said first and second introducers are adapted to be disposed in an adjacent configuration within the working channel of the endoscope.
