Abstract
A method for retrieving a previously inserted prosthetic valve is disclosed. In one example, a loader assembly is inserted through a hub of a delivery sheath device. The delivery sheath device includes an expandable sheath that extends into a blood vessel of a patient. The loader assembly is advanced in a distal direction until a distal section of the loader assembly extends into the expandable sheath which is attached to a distal end of the hub. The distal section has a larger inner diameter than a middle tube section of the loader assembly. A delivery catheter is retracted to move a prosthetic valve attached thereto in a proximal direction until the prosthetic valve is received within the distal section. The loader assembly and the delivery catheter are removed from a proximal end of the hub while the prosthetic valve is retained within the distal section.
