Abstract
A crimping device for reducing the size of prosthetic heart valve devices and other medical devices. A hydraulically operated piston advances a pusher toward an opening of a funnel. An interior surface of the funnel is configured to provide substantially uniform compression forces to a prosthetic heart valve device between the pusher and the funnel as the pusher advances the prosthetic heart valve device into the funnel. A system may comprise the crimping device and a prosthetic heart valve device positioned between the pusher and the funnel. A technique for using the crimping device includes delivering a pressurized fluid and crimping a prosthetic heart valve device using the interior surface of the funnel.
