Low profile stepped delivery system

A system for delivering an endoluminal prosthesis, the system comprising:

• a handle having a handle proximal end, a handle distal end, and a longitudinal bore;
• an elongated tubular member having a tubular member proximal end, a tubular member distal end, and at least one lumen between the tubular member proximal end and the tubular member distal end, the elongated tubular member being secured to the handle proximal end at the tubular member distal end;
• a sheath disposed at the tubular member proximal end, the sheath slidably mounted about the elongated tubular member in a longitudinal direction;
• an endoluminal prosthesis disposed at the tubular member proximal end, the endoluminal prosthesis being radially constrained by the sheath;
• a first trigger wire extending from the handle through the at least one lumen to the proximal end of the elongated tubular member, the first trigger wire coupled to a movement of the sheath;
• a second trigger wired extending from the handle through the at least one lumen to the proximal end of the elongated tubular member, the second trigger wire retaining the endoluminal prosthesis;
• and
• a wire coiling assembly disposed in the distal end of the handle, the wire coiling assembly comprising a rod having a first longitudinal surface with a first plurality of teeth, a second longitudinal surface having a second plurality of teeth, and a coiling mechanism comprising a first gear linked to the first plurality of teeth, a second gear linked to the second plurality of teeth, a first spool securing the first trigger wire and coupled to the rotation of the first gear, and a second spool securing the second trigger wire and coupled to the rotation of the second gear.
