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):

Minimally reactive surface

If you want to minimise adverse foreign body reactions and scarring associated with textile implants, besides using biocompatible material you have to provide the least possible contact area. The following formula applies: thread surface = bioreactive surface area of the implant. Our implants have a comparatively minimal reactive surface area, which means that they cause […]

Atraumatic selvedges

DynaMesh®products are not simply cut from a flat piece of mesh. Using our special warp knitting machines we are able to produce smooth and therefore atraumatic selvedges (no “sawtooth” edges). These “soft” selvedges make it easy for the surgeon to place and adjust the implant – without irritating or even damaging the surrounding tissue. And […]

Optimal dynamometry

Hernia surgery Textile implants must reinforce tissue, support muscles and protect organs. They have to cushion different forces without limiting mobility – including the extreme stresses associated with coughing, sneezing and laughing. What is needed therefore is an optimal interaction between predefined stability and elasticity. We achieve the optimal balance between these two properties. Pelvic […]

High tear propagation resistance

Conventional textile implants have a weak point: once torn or cut a zipper effect frequently occurs – the mesh continues to tear (mesh rupture). This does not happen with DynaMesh® products. The multiple meshing technique used in our warp-knitted structures does not allow this unwanted effect to occur in the first place. Tear propagation resistance […]

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 […]

visible in MRI

DynaMesh® visible – A better internal view without risk During MRI scans, in imaging terms the part of the body being analysed is scanned step by step and deconstructed into many “wafer-thin optical slices”. At the end, these “slices” are reconstructed to form 3-dimensional images or motion sequences (remodelling): The position of the DynaMesh® visible […]
