Low profile stepped delivery system

A delivery handle for an endoluminal prosthetic deployment system, the delivery handle comprising:

• a housing;
• and
• a rod slideably disposed within the housing, the rod comprising:
• a first end;
• a second end;
• an upper surface disposed between the first end and the second end, the upper surface having a first portion with a first set of gear teeth and a first smooth portion adjacent the first set of gear teeth;
• and
• a lower surface opposite the upper surface and disposed between the first end and the second end, the upper surface having a second smooth portion opposite the first set of gear teeth, and a second set of gear teeth adjacent the second smooth portion and opposite the first set of gear teeth;
• a gear assembly configured to sequentially engage the first and second sets of gear teeth, wherein the gear assembly comprises a first gear engageable with the first set of gear teeth and a second gear engageable with the second set of gear teeth,
• wherein a first trigger wire is engaged with the first gear and a second trigger wire is engaged with the second gear.

A delivery handle, the delivery handle

• comprising a housing, and a rod slideably disposed within the housing, the rod comprising:
• a distal end having an enlarged diameter portion;
• a proximal end axially opposite the distal end;
• a first surface disposed between the distal end and the proximal end, the first surface having a first portion disposed proximate the proximal end and having a set of gear teeth and a first smooth portion disposed proximate the distal end;
• and
• a second surface disposed between the distal end and the proximal end, the second surface having a second smooth portion disposed proximate the distal end, a third smooth portion disposed proximate the proximal end, and a second portion having a second set of gear teeth disposed between the second smooth portion and the third smooth portion
• a gear assembly engageable with the rod, the gear assembly comprising a first gear engageable with the first set of gear teeth, and a second gear engageable with the second set of gear teeth, and
• at least one trigger wire engaged with the gear assembly.
