Systems and devices for crimping a medical device and associated methods are disclosed herein. A crimping device configured in accordance with embodiments of the present technology can include, for example, a frame including a stationary plate, a movable member, and a plurality of blades arranged to form a channel and each including a pin that projects through a slot on the movable member and a corresponding slot on the stationary plate. The crimping device can be actuated to move the movable member relative to the stationary plate to drive the pins along paths defined by the slots to thereby drive the blades radially inward to crimp a medical device positioned within the channel.
