Technological Competence

Besides the synthesis of absorbable polymers, almost all possibilities for polymer processing from the melt and polymer solutions are available. This allows top-grade absorbable and non-absorbable fibers, yarns, monofilaments, non-woven materials, foils and membranes to be created from the polymers.

In combination with established textile processes (braiding, warp knitting, weaving and weft knitting), we implement developments from the molecule to the textile end product quickly and efficiently. The use of technologies and competencies for developing and manufacturing products is also possible outside the medical sector.

The development and production of medical products is certified according to ISO 13485 and takes place in clean rooms of class ISO 8.

Polymerisation of Absorbable Polymers
polymerisation reactor

Polymerisation of absorbable polymers in small and large polymerisation reactors in batch sizes from 1 kg to 50 kg, under clean room conditions. In addition to standard polymers, custom polymers can be synthesized if the client desires. Polymers can be added to the compounder to produce polymer blends.

Extrusion Techniques
filament extrusion

Multifilament extrusion

POY, FOY and FDY multifilament yarns in both mono- and bicomponent technology, across broad titer and strength ranges. In the mono-component area, production takes place under clean room conditions.

Monofilament extrusion

Monofilament extrusion and drawing in both mono- and bicomponent technology. Additives can be precisely dosed using gravimetric dosing. Production takes place under clean room conditions.



Injection Moulding
micro injection moulding

The babyplast micro injection moulding equipment enables the production of microparticles and inserts (e.g. pins), vascular closure systems after puncture, or the connecting by moulding of a textile implant with a needle adapter under clean room conditions.


Foil and Membrane Production
membrane production

Using coating knife and phase inversion technology, foils and membranes can be developed and manufactured under clean room conditions and used for adhesion prophylaxes and wound closure.

In addition to flat foil and membranes, capillary membranes can also be produced, which can be used as a nerve guidance channel, for example.

Punching in the clean room

On the hydraulic swivel arm punching machine type 1028 C from schoen + sandt, punching work up to a maximum area of 470 x 530 mm can be carried out in a class 8 clean room on customer order. What is needed is the individual punching tool, for which ITVP can provide assistance.

Coating Technology
coated sutures

Besides coating multifilament sutures, the various coating technologies can also be used to completely coat the surface of braided stents. Their surfaces are therefore made impermeable for application in the trachea and esophagus.

Using functional coating, medical implants are equipped antimicrobially or their surfaces are biologized. Moreover, the degradation behavior of absorbable implants can be adjusted to the indication using a coating.

Textile Technology
warp knitting in 2-D and 3-D technique

Non-woven Technology
clean room technology

A variety of non-woven technology is offered in close cooperation with the ITV Denkendorf. With spun-bounded technology, the melt-blow process and electro- and centrifuge spinning, a broad spectrum of filament diameters and porosities can be created: Custom-made for your product.

Possible applications include patches for occluders, scaffolds for regenerative medicine, but also products as complex as heart valves or meniscus replacements.
