1. A crimping device comprising:
a housing having a lumen configured to receive a prosthetic heart valve; and
a crimping band adjustably coupled to the housing and comprising a first end portion, a second end portion, and a loop, wherein the loop of the crimping band is disposed within the lumen of the housing and can be moved between a first configuration and a second configuration, wherein in the first configuration, the loop of the crimping band has a first diameter and is configured such that the prosthetic heart valve in a radially expanded configuration can be positioned radially within the loop, wherein in the second configuration, the loop of the crimping band has a second diameter and is configured to apply a radial force on the prosthetic heart valve to move the prosthetic heart valve from the radially expanded configuration to a radially compressed configuration, and wherein the loop of the crimping band is configured to contact less than one half of an axial length of the prosthetic heart valve,
wherein the housing comprises a band opening extending from the lumen of the housing to an outer surface of the housing, wherein in the band opening is configured such that the crimping band can extend therethrough.
