TRANSCATHETER PROSTHETIC HEART VALVE DELIVERY DEVICE WITH SUPPORT EXTENSIONS AND METHOD OF LOADING A PROSTHETIC HEART VALVE TO A 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.
