These simple radial compression machines have no electronics. They are suitable for a variety of applications in medical device manufacturing, R&D labs, and catheter labs. Designed with low-cost fabrication in mind, these crimpers are a bit less accurate and less powerful than the more expensive Blockwise crimpers, and are available in relatively short working lengths.

General-Purpose, Low-Force

Model RC

The world’s lowest-priced stent crimper. Zero die-to-die gap, easy viewing, variety of actuation methods. Used for many applications including precrimping (sizing) balloon-expandable stents, clamping or holding, and certain self-expanding stent loading applications.

Heart Valve-Sized, High Force

Model RSS

Blockwise’s lowest priced stent crimper is also very powerful. This innovative and proprietary mechanism provides high mechanical advantage, enabling the highest radial force available in a hand-actuated mechanism.  High visibility of the product. Useful for balloon-expandable heart valves and other balloon-expandable stents that don’t require heated dies. Suitable as a disposable tool in some applications.
