  • Patent number: 10828158
    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.

  • Publication number: 20190091021
    Abstract: A delivery device for a collapsible prosthetic heart valve includes a shaft having a longitudinal axis, at least a portion of the shaft being tubular with a wall thickness, a proximal end, and a distal end; and a retainer affixed to the shaft distally of the portion of the shaft, the retainer having at least one retainer pocket adapted to receive at least one retainer tab of the valve. The portion of the shaft includes an articulating pattern formed through the wall thickness, the portion of the shaft from the proximal end to the distal end being positioned along the longitudinal axis when the articulating pattern is in a relaxed condition, and at least a part of the portion of the shaft being oriented at an angle transverse to the longitudinal axis when the articulating pattern is in a flexed condition.
