1. A percutaneous valve delivery system, comprising:
an outer sheath;
an inner catheter disposed within the outer sheath, the inner catheter including a plurality of lumens formed therein;
a tubular member slidably received within one of the plurality of lumens and extending distally from a distal end of the inner catheter;
a nose cone fixedly attached to a distal end of the tubular member;
a handle attached to the outer sheath, wherein the handle is configured to shift the outer sheath between a first position and a second position relative to the inner catheter; and
a valve replacement implant releasably coupled to the inner catheter between a distal end of the inner catheter and a proximal end of the nose cone,
wherein in the first position, the nose cone includes a proximal portion configured to matingly engage a distal end of the outer sheath when in contact therewith, and when in the first position a distal end of the inner catheter is spaced proximally from the nose cone,
wherein the tubular member extends axially through the valve replacement implant when the valve replacement implant is coupled to the inner catheter,
wherein the nose cone is spaced distally from the outer sheath in the second position,
wherein the nose cone is disposed distally of the valve replacement implant when the valve replacement implant is coupled to the inner catheter.
