Abstract
Delivery devices and methods for delivering a stented prosthesis to a target site are disclosed. Disclosed delivery devices include a handle assembly including an actuator, an inner 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 tension management device that is configured to limit the amount of tension that can be applied via the actuator to the at least one tension member. Certain embodiments are configured to apply different tension limits to different tension members that are controlled by a one or more actuators. Other various embodiments include one or more tension adjustors to selectively adjust one or more tension limits.
