    摘要： A delivery apparatus for delivering a prosthetic implant includes a handle body, an outer shaft, and an inner shaft. The handle body includes a proximal end, a distal end, and a longitudinal axis extending between the proximal end and the distal end. The outer shaft includes a proximal end movably coupled to the handle body. The inner shaft extends through a lumen of the outer shaft and is fixed relative to the handle body. The inner shaft includes a first reinforcement layer and a second reinforcement layer. The first reinforcement layer extends from a proximal end portion of the inner shaft to a first distal location of the inner shaft. The second reinforcement layer extends from the proximal end portion of the inner shaft to a second distal location of the inner shaft, and the second distal location is proximal to the first distal location.

    摘要： Embodiments of a nosecone for a transcatheter delivery apparatus are disclosed. The nosecone can include a distal portion and a proximal portion. A longitudinal axis can extend from a distal end of the distal portion to a proximal end of the proximal portion. The proximal portion can have a shoulder region adjacent the distal portion of the nosecone and a body region proximal to the shoulder region. An outer surface of the nosecone can have a cross-sectional profile taken along the longitudinal axis of the nosecone. The cross-sectional profile of the body region can have a convex shape when viewed from a centroid of the body region.

    摘要： A delivery apparatus includes a handle body, a carriage, a first shaft, a second shaft, and a drive member assembly. The handle body includes proximal and distal ends and a cavity disposed between the proximal and distal ends. The carriage is disposed within the cavity and is axially movable relative to the handle body. The first shaft has a proximal end fixed relative to the carriage. The second shaft extends through a lumen of the first shaft and is fixed relative to the handle body. The drive member assembly includes a knob and a plurality of body members. The knob and each body member are formed as separate components. The drive member assembly is coupled to the carriage and the handle body such that rotating the knob relative to the handle body moves the carriage and the first shaft axially relative to the handle body and the second shaft.

    摘要： A prosthetic implant delivery assembly includes a prosthetic implant including an expandable stent and a catheter for delivering the prosthetic implant. The expandable stent includes apices circumferentially-spaced apart relative to each other. At least some of the apices include an aperture disposed therein. The catheter includes arms disposed at an end of a shaft, and the arms are moveable between a radially compressed state and a radially expanded state via a sheath. The arms each include a hook portion for releasably engaging the apertures of the apices. The arms are configured to move from the radially compressed state to the radially expanded state when the plurality arms is exposed from within the sheath such that the hook portion disengages from the apices of the prosthetic implant and releases the expandable stent from the catheter.
