  • a delivery catheter comprising an outer sheath with a proximal end portion and an inner sheath extending at least partially through the outer sheath, the inner sheath having a proximal end portion;

    a handle at a proximal end portion of the delivery catheter;

    a screw member positioned at least partially within the handle, the screw member configured for rotation about an axis within the handle, the screw member including an internal thread;

    a carriage positioned within the screw member and engaging the internal thread, the carriage coupled to the proximal end portion of the outer sheath; and

    an alignment member within the screw member, the alignment member contacting the carriage to limit rotation of the carriage about the axis as the screw member is rotated;

    wherein rotation of the screw member in a first direction about the axis causes the carriage to move in a first longitudinal direction within the screw member causing the outer sheath to move in the first longitudinal direction relative to the handle.
