    摘要： Various aspects of the present disclosure are directed apparatuses, systems and methods that include forming a constraining mechanism for an implantable medical device delivery. The apparatuses, systems and methods may include reducing a diameter of the implantable medical device from a deployed diameter to a reduced diameter and interlocking one or more fibers along a length of the implantable medical device while the implantable medical device is in the reduced diameter to form the constraining mechanism.

    摘要： A delivery apparatus can include a handle, a first shaft extending from the handle and having a proximal end portion coupled to the handle and a distal end portion and a second shaft extending coaxially over the first shaft and having a proximal end portion coupled to the handle and a distal end portion. The delivery apparatus can further include a shoulder coupled to the distal end portion of the second shaft and having a flared end portion configured to abut a prosthetic valve positioned around the first shaft in a radially compressed state, an extension portion extending from the shoulder, and at least one radiopaque marker disposed on the extension portion at a location within the prosthetic valve when the prosthetic valve is in a radially compressed configuration on the first shaft.
