1. A system for crimping a prosthetic valve comprising:
- a first funnel, the first funnel comprising a first diameter, a tapered section, and a second diameter smaller than the first diameter;
a second funnel, the second funnel comprising a first diameter, a tapered section, and a second diameter smaller than the first diameter;
a delivery device, the delivery device comprising a strut support and an outer sheath, at least a portion of the delivery device configured to extend through the first funnel and the second funnel; and
an actuator, the actuator configured to attach to the prosthetic valve and pull the prosthetic valve through at least one of the first funnel and the second funnel;
wherein the first diameter of the first funnel is larger than the first diameter of the second funnel.

23. A method for crimping a prosthetic valve comprising:
-
attaching the prosthetic valve to an actuator; advancing a first funnel over the prosthetic valve such that the prosthetic valve moves through the first funnel, the first funnel comprising a first diameter, a tapered section, and a second diameter smaller than the first diameter; advancing a second funnel over the prosthetic valve such that the prosthetic valve moves into the second funnel and onto a strut support of a delivery device, the second funnel comprising a first diameter, a tapered section, and a second diameter smaller than the first diameter; and advancing an outer sheath of the delivery device over the prosthetic valve on the strut support; wherein the first diameter of the first funnel is larger than the first diameter of the second funnel. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31)
