1. A system for crimping a prosthetic valve comprising:
a funnel having a first funnel diameter at a proximal end, a tapered funnel region, and a second funnel diameter at a distal end smaller than the first funnel diameter;
a retaining tube having: a first tube diameter at a proximal-most end,
a second tube diameter at a distal-most end,
a tapered region extending from the distal-most end and separating the first tube diameter and the second tube diameter, and
a constant diameter region of the first tube diameter extending from the tapered region to the proximal-most end,
wherein the second tube diameter is smaller than the first tube diameter, the first tube diameter is smaller than the second funnel diameter, and the retaining tube is configured to slide entirely through the funnel; and
a delivery device including:
a distal tip,
an inner shaft, and
an outer sheath having a sheath diameter smaller than the second tube diameter;
wherein the funnel is configured to provide a first crimping of the prosthetic valve, the retaining tube is configured to provide a second crimping of the prosthetic valve that is smaller than the first crimping, and the outer sheath is configured to provide a third crimping of the prosthetic valve that is smaller than the second crimping.
