DynaMesh®

Tailored Implants Made of PVDF

Effective Porosity

Optimal integration

During incorporation the filaments are enclosed by an internal and external granuloma. When filament distance is too small there is a risk that the whole of the intervening space will be filled with scar tissue (closed pores). The scar plates that develop in this way cause patients great discomfort. Sufficiently large pores can prevent this.

How is this prevented?
PP implants must have a pore diameter of at least 1 mm in all directions – under loading as well (!) (because of the lower granuloma thickness, just 0.6 mm is sufficient in the case of PVDF) – for the pores to remain open. Only in this way can local autochthonous tissue form through a pore [literature number 6,8].

Hernia

DynaMesh® warp-knitted fabrics provide this prerequisite because of their optimal pore geometry and the high effective porosity* (up to 69 %) achieved through this geometry .

Textile porosity refers to the permeable component of a mesh before the body has reacted to the implant.

*Effective porosity refers to the permeable component of a mesh after the body has reacted to the implant.

Rule of thumb:
A “pore” less than 1 mm in diameter is closed by the body with scar tissue = 0% effective porosity
