PROPERTIES OF TIMESH® TITANIZED POLYMERS
INERTNESS: TiMesh® is a composite mesh comprised of polypropylene and titanium. Both materials have widespread usage in implantation surgery.
MOLECULAR PERMEABILITY (pores/openings): A mesh material should be permeable for rapid fibrinous fixation of the mesh to the host tissue2. This reduces the risk of seroma formation by eliminating the potential space between the mesh and the host tissue2. TiMesh's thinness (0.3mm for Light and 0.2mm for Extra Light) means the mesh is characterized by excellent handling properties.8,6
PLIABILITY: Because TiMesh® is light weight and thin, it is extremely pliable (flexible). The rigidity and thickness are important determining factors in a surgeon's decision making because these factors impact conformability. The conformability determines the distance between the mesh-tissue interface. TiMesh® will conform around the anatomy leaving the area as pliable as normal tissue5.
TRANSPARENCY: TiMesh® is extremely transparent. This is due to the interstice (pore) size and because it is light weight (contributes to thinness). It is important to be able to see through the mesh when determining mesh coverage of the defect as well as for placing sutures or tacks.
MECHANICAL INTEGRITY: Even though TiMesh® is light weight, this does not mean it is more susceptible to failure. The main task of the biomaterials used for hernia repair is to strengthen the abdominal wall. However, the mesh and the resulting tissue reaction should not reduce the mobility and flexibility of the abdominal wall. The human abdominal wall fails at a load of 16 Newtons when the intra-abdominal pressure is 20kPa4. This results in a minimum load criterion for a hernia repair material assuming it is well fixed to the surrounding tissue. The Extra-light and Light TiMesh® materials are able to maintain tensile loads of up to 26 and 47 Newtons, respectively, prior to failure6.
BIOCOMPATIBILITY: TiMesh® demonstrates a high degree of biocompatibility. This is because of the titanium surface as well as the reduced amount of material. Optimal mesh features include those with a low potential for reactivity and inflammatory response.2
