1. A prosthetic heart valve delivery device, comprising:
- an elongate catheter tube having a first end portion, a second end portion, a first lumen, a second lumen, and a third lumen, wherein the first lumen is radially centrally disposed, the second lumen is disposed radially outwardly from the first lumen, and the third lumen is disposed radially outwardly from the first lumen and circumferentially spaced relative to the second lumen;
an elongate flexible member disposed in the second lumen of the catheter tube; and
an elongate stability member disposed in and axially moveable relative to the third lumen of the catheter tube and the flexible member, wherein the stability member comprises a C-shape and is relatively stiffer than the catheter tube and the flexible member.

17. A prosthetic heart valve delivery assembly comprising:
-
a prosthetic heart valve comprising an annular frame and a plurality of leaflets supported by the frame, wherein the frame is radially compressible to a compressed configuration and radially expandable from the compressed configuration to an expanded configuration; and a delivery apparatus comprising a catheter tube, a valve catheter, an elongate flexible member, and a stability member, wherein the catheter tube has a first lumen, a second lumen, and a third lumen, the first lumen being radially centrally disposed on the catheter tube, the second lumen being disposed radially outwardly from the first lumen, the third lumen being disposed radially outwardly from the first lumen and circumferentially spaced relative to the second lumen, and the valve catheter extending coaxially through the first lumen, wherein the prosthetic heart valve is mounted to a distal end portion of the valve catheter in the compressed configuration, wherein the flexible member is disposed in the second lumen of the catheter tube, and wherein the stability member disposed in and axially moveable relative to the third lumen of the catheter tube, wherein the stability member comprises a C-shape and is configured to be relatively stiffer than the catheter tube and the flexible member. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
