1. A catheter assembly for crimping an expandable prosthesis, the catheter assembly comprising:

  • a handle assembly located on the proximal end of the catheter assembly;

    a distal tip assembly located on the distal end of the catheter assembly and having a distal tip assembly diameter;

    a first elongate member, the first elongate member extending from the handle assembly towards the distal tip assembly; and

    a crimping funnel slidably positioned over the first elongate member and the distal tip assembly, the crimping funnel comprising;

    a distal end having a first diameter;

    a proximal end having a second diameter smaller than the first diameter, the proximal end having an axial split, wherein the second diameter is less than the distal tip assembly diameter; and

    a first collar encompassing a portion of the proximal end, wherein the first collar is configured to hold the axial split in the proximal end together when the first collar is at a first axial location along the proximal end, and wherein the first collar is configured to allow the axial split in the proximal end to open when the first collar is at a second axial location along the proximal end,wherein the axial split allows the second diameter of the proximal end of the crimping funnel to increase to a diameter larger than the distal tip assembly, when the first collar is in the second axial location,wherein the crimping funnel is positioned over the first elongate member such that the first elongate member is disposed within the proximal end of the crimping funnel and the distal tip assembly is disposed within or distal of the distal end of the crimping funnel such that the distal tip assembly is disposed distal of the first diameter with the first collar at the first axial location.
