Sized for Heart Valves

Disassembles Easily

Variety of Actuation Types

Models RVS, RVD, RVJ, RVSS

The Blockwise type M2 radial compression stations are simple, low-cost crimpers with no electronics, suitable for a wide variety of applications in medical device manufacturing, R&D labs, and catheter labs

These crimpers are sized appropriately for typical prosthetic heart valves, and designed to be easily disassembled for cleaning. Compared with more expensive Blockwise crimpers, type M2 is shorter in length, slightly less powerful, and slightly less accurate at small diameters. Type “M2” compression stations have 9 dies made from POM acetal copolymer. The design is type of Zero-G™ mechanism, with essentially zero die-to-die gap.
