US Patent 12115089 Clamshell iris-style crimper for medical devices

A crimper includes atop iris shell defining atop iris channel. The crimper also includes abase iris shell coupled to the top iris shell at a pivot connection, the base iris shell defining a base iris channel. The top iris shell is configured to rotate about the pivot connection relative to the base shell from an open state to a closed state. When in the open state, the base iris channel is exposed for loading the expandable medical device. When in the closed state, the top iris channel and the base iris channel define a crimper chamber. The crimper also includes a handle configured to operate the clamshell crimper. The actuation of the handle decreases a volume of the crimper chamber to transition the expandable medical device from the uncompressed state to the compressed state.
