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.
