Tracheal prosthesis, made of bacterial cellulose

Tracheal prosthesis is one of the potential biomedical applications of the innovative technology, based on the use of bacterial cellulose and developed by the  Bionanocellulose Team of the Institute of Technical Biochemistry.

Tracheal prosthesis products available on the market are made mainly of synthetic materials, often reinforced by metallic elements or carbon fibres, which reduce implant functionality, while increasing the incidence of rejection.

The method developed by the team enables a fragment of tracheal prosthesis to be made of bacterial cellulose in the form of an elastic coil. Such a prosthesis mimics the natural fragment of the trachea in the section from the larynx to the tracheal bifurcation. With the use of a mercerisation process, the bacterial cellulose takes the form ringed cartilage assuiming the function of tracheal cartilages.

This prosthesis is characterised by mechanical properties close to those of natural tissue and is made exclusively of biocompatible and biodegradable material, which increases its potential for acceptance by the human body.

This product, offered for use in surgery of soft and hard tissues, is dedicated to medical and pharmaceutical manufacturers.
