Low Profile Stepped Delivery System
First Claim
1. A system for actuating a trigger wire in a delivery device, the system comprising:
- a handle having a handle proximal end, a handle distal end, and a longitudinal lumen between the proximal and distal ends;
a rod disposed within the longitudinal lumen, the rod having a rod proximal end, a rod distal end, a first longitudinal surface with a first engagement mechanism disposed at a first angular orientation between the rod proximal end and the rod distal end, and a second longitudinal surface having a second engagement mechanism disposed at a second angular orientation between the proximal rod end and the distal rod end, wherein the rod is movable from a first axial position to a second axial position;
a wire coiling assembly disposed within the handle, the wire coiling assembly;
comprising a first rotary gear having a rotation linked to an axial movement of the first engagement mechanism,a second rotary gear linked to an axial movement of the second engagement mechanism,a first wire spool coupled to the rotation of the first rotary gear, the first wire spool windingly attached to a first retractable wire, anda second wire spool coupled to the rotation of second rotary gear, the second wire spool attached to a second trigger wire.

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.
