    Abstract: Embodiments of a prosthetic valve delivery apparatus are disclosed. The delivery apparatus includes a first portion configured to maintain a fixed spatial relationship relative to a first end of the prosthetic valve and a second portion configured to maintain a fixed spatial relationship relative to a second end of the prosthetic valve during radial expansion of the prosthetic valve. The first portion includes one or more reference radiopaque markers and the second portion includes an indicator radiopaque marker. A position of the indicator radiopaque marker relative to the one or more reference radiopaque markers measures an axial distance between the first and second ends of the prosthetic valve indicative of a corresponding diameter of the prosthetic valve as it is radially expanded from a radially compressed state to a radially expanded state.

    Abstract: A prosthetic valve delivery apparatus can comprise a handle, a gearbox, an input torque shaft and a plurality of output torque shafts. The input torque shaft can extend distally from the handle and can have a distal end portion operatively connected to the gearbox. The output torque shafts can be operatively connected to and extend distally from the gearbox. Rotation of the input torque shaft can cause rotation of the output torque shafts via the gear box.

    Abstract: An expandable sheath is disclosed herein, which has a first polymeric layer and a braided layer positioned radially outward of the first polymeric layer. The braided layer includes a plurality of filaments braided together. The expandable sheaths further include a resilient elastic layer positioned radially outward of the braided layer. The elastic layer is configured to apply radial force to the braided layer and the first polymeric layer. The expandable sheath further includes a second polymeric layer positioned radially outward of the elastic layer and bonded to the first polymeric layer such that the braided layer and the elastic layer are encapsulated between the first and second polymeric layers. Methods of making and using the devices disclosed herein are also disclosed, as are crimping devices that may be used in methods of making the devices disclosed herein.
