TiMESH


US customers: For product details please refer to our US-Website.

The TiMESH mesh implant is used in hernia surgery for all kinds of hernias and surgical techniques including IPOM. Thanks to its outstanding biocompatibility, it ensures excellent quality of life and shorter convalescence.


Benefits

Outstanding biocompatibility  The mesh implant is titanised, very lightweight and hydrophilic and thus outstandingly biocompatible.

Excellent quality of life combined with shorter convalescence  Outstanding biocompatibility keeps inflammation rates, shrinkage and migration to a minimum and ensures shorter convalescence. The implant is not recognized as a foreign body, and postoperative pain is prevented.

Globally unique technology  The nanotechnological finishing process for the covalent bonding of polypropylene and the titanium-dioxide surface is patented and thus completely unique.

Practice

Implantation

TiMESH is suitable for the treatment of all kinds of hernias (inguinal, incisional, ventral, umbilical, femoral, parastomal, hiatal), using open and laparoscopic implantation (e. g. TAPP, TEP).

The following implantation options are available for the treatment of incisional hernias with TiMESH:

  1. in the peritoneum
  2. between the abdominal wall and the peritoneum  
  3. before the deep muscle layer

Knowledge

Titanisation

Chemical vapour deposition (CVD) is a process for the metallisation of complex components, while at the same time achieving well-adherent bonds. However, as this process involves temperatures in excess of 150 °C, it is not an option for many prosthetic materials which would not be shape-retentive at such temperatures (e.g. polypropylene).

For that reason, the titanisation of plastic implants takes place at low temperatures using a special plasma-coating process known as PACVD (plasma-activated chemical vapour deposition).

Plasma is the term used for an excited (ionised) gas. In that state, the atoms/molecules are highly energetic. Nevertheless, plasma is not hot. In everyday life, we are familiar with plasma in fluorescent tubes. The electrically charged gas components emit light as the result of their highly energetic state, but the fluorescent tube remains cold.

In the titanisation process, gaseous titanium is introduced into the coating chamber as a precursor.  By adding energy in form of plasma, the precursor is split into individual ionised atoms. At their surface, these ionised titanium atoms have free electrons.

In addition to the precursor, the plasma also excites the surfaces of the plastic implants, with the result that their surfaces also show free electrons. The ionised titanium atoms come into contact with the ionised surface of the implant, resulting in the respective free electrons forming covalent bonds. Covalent bonds are seen as the strongest of chemical bonds; the titanium is thus almost indissolubly bonded to the plastic.

This process creates a composite material, whose surface is coated with an ultra-thin, approx. 30 – 50 nm (1 nanometre = 1 millionth of a millimetre), highly biocompatible layer of titanium.  The coating is so thin as to be transparent, but also highly flexible.

Because the titanium cursor is introduced in gaseous form, it reaches all parts of the plastic implant. As the result, the entire surface, including gaps in between complex shapes, is completely and evenly titanised.

Application Range

Indication

TiMESH is used for the surgical treatment of tissue defects.

TiMESH is particularly suitable for the laparoscopic and open treatment of direct and indirect inguinal, femoral, umbilical and incisional hernias (including preperitonaeal and intraperitonaeal mesh positioning) as well as for parietal tissue strengthening and repairs to the abdominal wall.
