The lead screw engages the lead screw nut and rotation of the lead screw causes the delivery sleeve to retract relative to the valve catheter and the prosthetic valve for exposing the prosthetic valve. The flexible extensions of the mop allow expansion of the valve while maintaining the attachment during placement of the valve at a native valve site. ...
