1. A delivery device comprising:
- an inner shaft having one or more delivery platforms for deployment of one or more intraluminal devices;
an outer sheath surrounding the inner shaft and configured to cover the one or more delivery platforms pre-deployment and to be withdrawn from one of the one or more delivery platforms as part of a deployment of one of the one or more intraluminal devices;
a handle housing having a trigger mechanically linked to the outer sheath such that actuation of the trigger withdraws the outer sheath from covering one of the one or more delivery platforms;
an interlock that when in a locked position is engaged with the trigger and the inner shaft to thereby prevent movement of the outer sheath when the interlock is engaged;
a ramp interface between the interlock and the inner shaft, wherein the ramp interface is configured to adjust the position of the inner shaft relative to the outer sheath when the interlock is removed from engagement with the inner shaft; and
wherein the ramp interface comprises a first ramp on a protrusion of the interlock and a second ramp on the inner shaft, wherein sliding disengagement of the first and second ramps forces the inner shaft to move.

10. A delivery device for deploying a medical implant within a vessel, the delivery device comprising:
-
an inner shaft having one or more delivery platforms for deployment of one or more medical implants; an outer sheath having a proximal end and a distal end, the outer sheath adapted to extend over the one or more medical implants on the inner shaft in a collapsed position and to be retractable to expose the one or more collapsed medical implants for deployment; an interlock that when in a locked position is configured to prevent retraction of the outer sheath; and a handle having; a control mechanism including an actuation assembly coupled to the proximal end of the outer sheath for retracting the outer sheath with respect to the inner shaft; one or more slots therein configured to receive the interlock, wherein the delivery device is further configured such that retraction of the outer sheath is prevented when the one or more slots receive the interlock; and an interface configured such that disengagement of the interlock from the interface on the handle causes the inner shaft to advance within the outer sheath. - View Dependent Claims (11, 12, 13, 14, 15)
