Stent Crimper, Radial Compression, Balloon-Expandable Stent Crimping - Blockwise Engineering

These machines compress balloon-expandable stents, attaching them to balloon catheters. These machines also serve as general-purpose radial compression machines for various applications. Optional film sheathing protects fragile product surfaces. The machines comprise two parts: 1) a "compression station", the mechanism that provides a variable-diameter, cylinder-shaped opening, and 2) the machine base that controls the process.

Electric Actuation - Model CX

The world's best stent crimper. Superior precision and repeatability of diameter or force control make it the the best machine for production. Total flexibility in recipe setup and manual control make it the best machine for R&D. Very easy to learn, use, and calibrate.

Simple Manually-Controlled Pneumatic Actuation - Model RJ

Uses the same compression stations as the CX machine, but does not provide computerized control or timing. Force is adjusted by setting the regulated air pressure, and diameter is adjusted by a stop-screw. A toggle valve opens and closes the compression station.
