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 to a minimum, prevents shrinkage and migration 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.
Customised products Individual mesh implants according to customer requirements complement the comprehensive, indication-specific portfolio of mesh implants. This has been made possible thanks to a special approval process for customised products.

Implantation
A longitudinal incision is made in the anterior vagina and free preparation is performed of the vaginal wall up to the vaginal stump. The pararectal space is visualised up to the sciatic spine. The needles are inserted at the anterior upper edge and the lower anterior edge of the obturator foramen, and the arms on both sides are then guided under digital monitoring. TiLOOP® Four is fixed to the needle and the anchor introduced. This procedure is performed on both sides. The TiLOOP® Four is fixed to the base of the vagina. The vagina is closed and tension-free elevation is then performed.
Titanisation
Chemical vapour deposition (CVD) is a process for the metallisation of complex components while at the same time achieving strong 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 stage, atoms/molecules are highly energetic. However, 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. These ionised titanium atoms have free electrons at their surfaces.
In addition to the precursor, the plasma also excites the surfaces of the plastic implants with the result that their surfaces also have free electrons. The ionised titanium atoms come into contact with the ionised surface of the implant resulting in the formation of covalent bonds with the free electrons. Covalent bonds are seen as the strongest of chemical bonds; the titanium is thus almost permanently 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 that it appears to be transparent and is also highly flexible.
Because the titanium precursor 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.
Indication
TiLOOP® mesh implants were developed for a variety of indications in urological, gynaecological and surgical patient treatment within the broad range of procedures that use surgical mesh implants.
TiLOOP® mesh implants are particularly used for supporting and strengthening of connective tissue structures and ligaments.
TiLOOP® Four: cystocele; for pelvic floor reconstruction (surgical treatment of complex cystocele defects)
The tension-free TiLOOP® Four pelvic floor mesh is used for the stabilisation and elevation of cystoceles or in cases of vaginal stump prolapse.
