Apparatuses, systems, and methods for crimping prosthetic implants onto a delivery apparatus are disclosed. In some examples, a system for crimping a prosthetic valve to a delivery apparatus includes a support body having a central channel and a support surface that extends around the central channel, the support surface configured to receive the prosthetic heart valve thereon and the central channel configured for the delivery apparatus to extend therethrough. The system further includes a crimping device including a channel configured to receive the prosthetic heart valve and a first opening to the channel on a first side of the crimping device, the first opening configured to receive the support body therethrough.
