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

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.

  • Model RCC Manual Lever Actuated Crimper

    Diameter Length Max Radial Force Die Material
    0 - 29 mm 38 mm 425 N POM Acetal Copolymer

  • Model RCD Air Actuated Crimper

    Diameter Length Max Radial Force Die Material
    0 - 26 mm 38 mm 425 N POM Acetal Copolymer

  • Model RCS Manual Screw Actuated Crimper

    Diameter Length Max Radial Force Die Material
    0 - 26 mm 38 mm 425 N POM Acetal Copolymer

Heart Valve Sized, Medium Force

Size range and force range covers typical prosthetic heart valve applications. Used in many other applications where a larger or stronger low-cost crimper is needed.

  • Model RVD Air Actuated Crimper

    Diameter Length Max Radial Force Die Material
    0 - 41 mm 25 or 50 mm 600 N POM Acetal Copolymer

  • Model RVS Hand Crank Actuated Crimper

    Diameter Length Max Radial Force Die Material
    0 - 41 mm 25 or 50 mm 600 N POM Acetal Copolymer

  • Model RVSS Hand Crank, Steam Sterilizable Crimper

    Diameter Length Max Radial Force Die Material
    0 - 41 mm 25 or 50 mm 600 N Polysulfone

Heart Valve-Sized, High Force

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.

  • Model CX with TQP Torque Pal™ Module and RSS Crimper

    Diameter Length Max Radial Force Die Material
    0 - 36 mm 50 mm 2700 N POM Acetal with PTFE

  • Model RSS Hand Crank Crimper

    Diameter Length Max Radial Force Die Material
    0 - 36 mm 50 mm 2700 N POM Acetal with PTFE
