Abstract
A delivery device (10) for a collapsible prosthetic heart valve may include an operating handle (20, 220, 320) having a housing (30, 230, 330) and a carriage selectively (40) fixed or movable relative to the housing, and a catheter assembly (16, 116, 216, 416). The catheter assembly may have an inner shaft (26, 126, 226, 326, 426) around which a compartment (23) is defined, an outer shaft (22) surrounding at least a portion of the inner shaft, a distal sheath (24) fixedly connected to the outer shaft, and a mechanism configured to apply a distal force to the outer shaft while the carriage (40) is fixed relative to the housing (30, 230, 330) to stretch the outer shaft from a compressed length to an extended length. The extended length may be greater than the compressed length along an axis of elongation of the outer shaft (22).
