1. A delivery device for implanting a stented prosthetic heart valve, the delivery device comprising:
a handle;
an inner shaft assembly extending from the handle and including a shaft and a valve retainer, the inner shaft assembly defining a guide wire lumen, the valve retainer terminating at a proximal face that surrounds a proximal opening of the guide wire lumen;
an outer sheath assembly including a capsule slidably received over the inner shaft assembly, wherein the capsule is configured to compressibly retain a stented prosthetic heart valve;
a guide wire exit port proximal of the capsule and distal of the handle, the guide wire exit port being open to the guide wire lumen;
a connector assembly comprising a first tube and a second tube that define a guide wire passageway between the proximal opening and the guide wire exit port, the first tube connected to the outer sheath assembly and defining the guide wire exit port, the second tube connected to the valve retainer; and
a first support body along an exterior of the outer sheath assembly proximal of the guide wire exit port, the first support body configured to slidably receive a guide wire.
