Explore more information about influences of mesh porosity and other key parameters driving mesh performance.

Pore size

 

Having large pores does not require having to accept low weight (surface density).

 

Tensile strength

 

Tensile strength (minimum) and surface density (weight) are correlated.

 

 

The ideal mesh

Meshes long term tolerance depends on their physical and mechanical properties

Macroporosity should reach 1.5 mm for optimal tissue ingrowth and shrinkage minimization4

The weight, as sole parameter, does not matter
