Abstract: Delivery devices and device elements that provide steering capabilities and methods of steering such delivery devices during the delivery of a stented prosthesis to a target site. Various delivery devices include a shaft assembly having a plurality of lumens through which tension members that compressively retain the stented prosthesis to the shaft assembly are routed. By selectively tensioning one or more tension members, the shaft assembly can be pulled or steered in a desired direction. Various embodiments include one or more steering or stiffening rods that can reinforce the device or counteract any unintended bending or steering of the delivery device.

Abstract: A system including a prosthetic heart valve and a delivery device. The prosthesis includes a stent frame supporting a valve structure. The stent frame is transitionable between compressed and expanded conditions. The delivery device includes outer and inner shaft assemblies. The outer shaft assembly includes a capsule extending distally from an outer shaft. The inner shaft assembly is coaxially received within the outer shaft assembly, and includes an inner shaft, a valve retainer, and a tip unit. A proximal section of the tip unit extends from, and has an outer diameter greater than, the inner shaft. In a delivery state, the prosthesis is contained in the compressed condition over the inner shaft assembly by the capsule, a first region of the stent frame is connected to the valve retainer, and at least a portion of a second region of the stent frame contacts the proximal section of the tip unit.
