Claim:
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sheath surrounding the inner shaft and configured to cover the one or more delivery platforms pre-deployment and to be withdrawn from one of the one or more delivery platform as part of a deployment of one of the one or more intraluminal devices; an outer sheath rack comprising a plurality of teeth, the outer sheath rack coupled to the outer sheath; a handle housing, wherein the inner shaft and the outer sheath rack are at least partially positioned within the handle housing, the handle housing comprising at least one pawl configured to engage with the plurality of teeth on the outer sheath rack to prevent re-sheathing of the outer sheath over the one or more delivery platforms after a deployment; and a retraction override switch coupled to the outer sheath rack and the inner shaft, wherein actuation of the retraction override switch is configured to disengage the at least one pawl from the plurality of teeth on the outer sheath rack to allow re-sheathing of the outer sheath over the one or more delivery platforms after a deployment; wherein the outer sheath rack and outer sheath are coupled to the retraction override switch such that actuation of the retraction override switch causes the outer sheath rack to move out of engagement with the at least one pawl, wherein the retraction override switch is configured such that actuation of the retraction override switch causes the retraction override switch to rotate with respect to the handle housing, and wherein the outer sheath rack is configured such that actuation of the retraction override switch causes the outer sheath rack and the outer sheath to rotate with respect to the handle housing.
