Beschreibung
Zusammenfassung:	A hub is slidable along a straight track, and an introducer sheath is fixed to and extends distally from the hub. A proximal handle is longitudinally slidable along the straight track and defines a helical track that has a travel length along the longitudinal axis. The hub and the proximal handle are mated, whereby rotation of the handle about the hub causes longitudinal travel of the hub and retraction of the introducer sheath from a prosthesis radially constrained within the introducer sheath. The hub proximally slidable along with straight track, thereby enabling retraction of the introducer sheath from the prosthesis by at least one of travel of the hub along the helical track during rotation of the proximal handle about the longitudinal axis, and by proximal longitudinal movement of the proximal handle along the straight track.
