Shock Z is a lab test that subjects the suture material to considerable pressure for the purpose of evaluating its elastoplastic properties.
It is performed on threads that are to be used for suturing tissues which have to withstand physiological variations in pressure, as is the case with the abdominal wall.
Monomax®, a monofilament suture specially designed for abdominal wall closure, was tested under these conditions and resisted variations in pressure equivalent to the abdominal pressure, without becoming deformed, for a long period of time. The results of this test show that Monomax® has unique elastoplastic properties.
