A steerable sheath includes an inner liner extending from a proximal end to a distal end of the steerable sheath. The inner liner includes a non-deflectable portion and a deflectable portion. The steerable sheath includes a first pull wire positioned along a first helical path around the circumference of the inner liner from a proximal end to a distal end of the non-deflectable portion of the inner liner and along a first straight path from a proximal end of the deflectable portion to a distal end of the deflectable portion. The steerable sheath includes a second pull wire positioned along a second helical path around the circumference of the inner liner from the proximal end to the distal end of the non-deflectable portion and along a second straight path from the proximal end of the deflectable portion to the distal end of the deflectable portion.

Retainer structures () maintain stented valves () on the balloon () of a balloon catheter during delivery of the valve to an implantation node and subsequent expansion of the valve. The retainer structures define a raised edge relative to the outer surface of the balloon and limit movement of the valve longitudinally relative to the balloon. Deflation of the balloon following expansion of the valve stent releases the valve.
