Claim 8:
9. A delivery device for delivering a stented prosthetic heart valve including a valve structure carried by a stent frame configured to self-expand from a collapsed condition to a normal, expanded condition, the delivery device comprising:
an inner shaft forming a lumen;
a spindle extending from the inner shaft along a spindle axis, wherein the spindle defines a first hole open to the lumen and an exterior of the spindle, and a second hole open to the lumen and the exterior of the spindle, and the second hole is distally spaced from the first hole in an axial direction of the spindle axis;
a first cord slidably disposed within the lumen and extending through the first hole for selectively cinching the stented prosthetic heart valve at a first axial location of the stented prosthetic heart valve;
a second cord slidably disposed within the lumen and extending through the second hole for selectively cinching the stented prosthetic heart valve at a second axial location of the stented prosthetic heart valve, wherein the second axial location is distally spaced from the first axial location in the axial direction of the spindle axis; and
a lateral control feature configured to bias the spindle to a selected lateral location relative to the stented prosthetic heart valve tethered to the spindle in a tethered and expanded state, wherein the lateral control feature includes a first spring configured to apply a tension to the first cord, and the first spring is located within the spindle and interconnects the first cord to a tension control rod.
