Abstract
A crimping device includes a housing and a crimping band. The housing has a lumen for receiving a prosthetic valve. The crimping band is adjustably coupled to the housing and has a first end portion, a second end portion, and a loop. The loop of the crimping band is disposed within the lumen and move between first and second configurations. In the first configuration, the loop has a first diameter and is configured such that the prosthetic valve in a radially expanded configuration can be positioned radially within the loop. In the second configuration, the loop has a second diameter and is configured to apply a radial force on the prosthetic valve to move the prosthetic valve to a radially compressed configuration. The loop of the crimping band is configured to contact less than half of an axial length of the prosthetic valve.
