Future-orientated

More than a hundred years ago the company began manufacturing sterile catgut, and later also successfully established itself as the producer of sterile liquid medicinal products. Production efficiency at the plant in Upper Franconia is not only a tradition but also has a great future: the combination of precise craftsmanship and high-tech industrial manufacturing processes meets the highest quality demands for routine production, small-scale production and special designs.

In a cleanroom area of more than 2000 m², we manufacture textile implants, surgical suture material, infusion and irrigation solutions in accordance with the latest research and state-of-the-art technology. In addition, interdisciplinary teams of in-house and external doctors, pharmacists, biologists, chemists, and engineers develop new, improved, and better-tolerated materials, as well as novel methods of treatment.

Our new logistics centre with a floor space of 6,100 m² is now available to improve the shipping process and for the storage of drugs and medical devices.

Looking back:

In the year 1866, Carl Wiessner founded a company that would come to combine tradition and innovation in many ways.

At the beginning of the 20th century he started the industrial manufacture of sterile catgut. The years that followed were eventful, culminating in 1945 with the destruction caused by World War II, which led to the company being relocated to northern Bavaria. Nine years later, in 1954, the new plant was opened in Naila in Upper Franconia. Amalgamating Carl Wiessner’s catgut production plant with SERAG in 1961 to form SERAG-WIESSNER brought the company much greater production potential. From this time onwards, development has been dynamic and future-orientated:
