Abstract

The delivery systems disclosed herein can create simultaneous movement of an inner and an outer sheath of the delivery system. The delivery systems can generally include a handle assembly and a delivery catheter. In certain embodiments, the inner shaft and the outer sheath can be slidably controlled by a control element in the handle. The handle assembly can include a housing with a thumbwheel acting as the control element. In certain embodiments, movement of the inner shaft and the outer sheath can be caused via a gear-type system. In certain embodiments, the handle assembly can include a rotatable housing. A control element can rotate the housing, which can cause a first boss associated with the outer sheath and a second boss associated with the inner shaft to move in opposite directions.
