Abstract
A delivery device () for a collapsible prosthetic heart valve may include an operating handle () having a housing () and a carriage selectively () fixed or movable relative to the housing, and a catheter assembly (). The catheter assembly may have an inner shaft () around which a compartment () is defined, an outer shaft () surrounding at least a portion of the inner shaft, a distal sheath () fixedly connected to the outer shaft, and a mechanism configured to apply a distal force to the outer shaft while the carriage () is fixed relative to the housing () 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 ().
