Low profile stepped delivery system
First Claim
1. A delivery handle for use in a endoluminal prosthetic deployment system comprising:
- a housing;
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 smooth portion disposed proximate the proximal end and a first toothed portion 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 and opposite the first toothed portion, and a second toothed portion disposed proximate the proximal end and opposite the second smooth portion;
a gear assembly engageable with the rod having a first gear engageable with the first toothed portion, and a second gear engageable with the second toothed portion, andat least one trigger wire engaged with one of the first or second gears of the gear assembly.

Abstract
A low profile stepped delivery system for retracting trigger wires from a prosthesis to release the prosthesis from a delivery device. A rod is disposed within an axial bore of a handle. The rod has a first longitudinal surface and a second longitudinal surface. A first engagement mechanism is disposed on the first longitudinal surface and a second engagement mechanism disposed on the second longitudinal surface. A wire coiling assembly is disposed at an end of the of the handle and comprises a first rotary gear that is adapted to be rotated by the first engagement mechanism, a second rotary gear that is adapted to be rotated by the second engagement mechanism, a first wire spool that is coupled to a rotation of the first rotary gear, and a second wire spool that is coupled to the rotation of second rotary gear. The first wire spool is configured to secure a first trigger wire and the second wire spool is configured to secure a second trigger wire.
