1. Apparatus, comprising:
a delivery tool, comprising:
a first catheter;
a second catheter;
having a steerable distal portion, and
extending through the first catheter such that the steerable distal portion of the second catheter is disposed out of a distal end of the first catheter;
an extracorporeal second-catheter controller:
coupled to a proximal portion of the second catheter, and
operably coupled, via the second catheter, to the steerable distal portion of the second catheter such that operating the extracorporeal second-catheter controller steers the steerable distal portion of the second catheter;
a rod:
having a steerable distal portion, and
extending through the second catheter and out of a distal end of the second catheter such that the steerable distal portion of the rod is disposed out of the distal end of the second catheter; and
an extracorporeal rod-controller:
coupled to a proximal portion of the rod, and
operably coupled, via the rod, to the steerable distal portion of the rod such that operating the extracorporeal rod-controller steers the steerable distal portion of the rod independently of the steering of the steerable distal portion of the second catheter by the extracorporeal second-catheter controller; and
a prosthetic valve:
comprising a first frame, and a second frame coupled to the first frame, wherein the apparatus has a delivery state in which (i) the prosthetic valve is compressed onto the steerable distal portion of the rod, distal to the distal end of the second catheter, and (ii) the prosthetic valve is transfemorally and transseptally advanceable into a left atrium of a heart of a subject by transfemorally and transseptally advancing the delivery tool.
