Tailored Implants Made of PVDF

Excellent Material: PVDF

The filament (“yarn”) we spin from the high-tech polymer PVDF is the first guarantee of the high quality of DynaMesh®products: a filament with many positive “natural” properties.  The textile structures warp-knitted from this are the second guarantee.

Very high body compatibility
PVDF filaments have excellent biocompatibility and reduce adverse foreign body reactions, such as scar contractions or pain. In addition, they are finer and smoother than conventional filaments. So PVDF is associated with substantially lower granuloma formation (scar tissue) compared with conventional polymers [2,3,4].

Reduced bacterial adherence
Scientific studies* from Aachen University (RWTH) Hospital demonstrate that lower quantities of bacteria adhere to textile implants made from pure PVDF (reduced bacterial adherence).
This is a significant finding for all open techniques because the risk of infection drops substantially with lower bacterial adherence.

A comparison of 100% PVDF (polyvinylidene fluoride) with 100% PP (polypropylene) and 50% PP + 50% absorbable component. In this study, cultures of reference strains of relevant bacteria were applied to different meshes. A subsequent fluorescence measurement clearly showed that the smallest quantity of bacteria had colonised meshes made from pure PVDF.


High ageing resistance
It is not just experience that shows that PVDF provides lasting success in many surgical disciplines. A long-term study over seven years has demonstrated that the condition of the PVDF surface remains unchanged. Thread and warp-knitted fabric remain stable and othing becomes brittle [2].

A long-term trial (7 years):

  • PVDF loses only 7.5% tensile strength
  • PP loses 46.6% tensile strength
    and stiffens
