Abstract
A device for crimping an expandable medical device and loading the expandable medical device into a delivery system includes an actuator, a compression assembly, and a pusher. The compression assembly is disposed in a compression chamber of the actuator and includes a plurality of compression elements coupled to each other to form a central cavity. The compression elements are coupled to the actuator such that rotation of the actuator causes the compression elements to rotate such that the central cavity radially compresses from an expanded configuration to a compressed configuration. The pusher includes a pusher rod and is configured to translate relative to the actuator towards the compression chamber when the cavity is in the compressed configuration such that the pusher rod may enter the cavity and push the medical device out of the cavity into delivery system.
