Abstract
Delivery devices for delivering a stented prosthesis to a target site are disclosed. Certain disclosed delivery devices include a handle assembly including an actuator, a shaft assembly interconnected to the handle assembly, and are configured to releasably retain the stented prosthesis to the delivery device with at least one elongate tension member. The delivery devices further include a torque shaft that is configured to apply and adjust the amount of tension in the each tension member. For example, the torque shaft can be configured to wind and unwind each elongate tension member around the torque shaft to correspondingly compress and expand the stented prosthesis. The torque shaft can be controlled with an actuator provided in the handle assembly, for example. In some embodiments, the actuator is further configured to axially move the torque shaft.
