Abstract
A delivery device for a collapsible prosthetic heart valve may include an operating handle having a housing and a carriage 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 spline tube surrounding at least a portion of the inner shaft. The spline tube may have thinner portions having a first maximum thickness in a radial direction of the inner shaft and thicker portions having a second maximum thickness in the radial direction that is greater than the first maximum thickness. The spline tube and the outer shaft may together define one or more channels that provide liquid communication between the operating handle and the compartment.
