POLTISS (Polymer Tissue) is a medical device company, which was founded in 2015 to introduce PhotoBioCure™ technology of modern, light activated, adhesive polymer biomaterials to the market.

Our aim is to develop the technology and a wide range of applications, such as soft tissue regeneration.

Our technology is based on polymeric materials, which under the influence of UV radiation turns from a sticky paste into a flexible solids. The composition is fully biodegradable in a living environment and eventually replaced by natural tissue.

PhotoBioCure™ properties are especially relevant to minimally invasive surgery that is increasingly performed to reduce postoperative complications, recovery times, and patient discomfort.


We are supported by YouNick Mint fund which is specialized in healthcare technologies commercialization.


POLTISS closely cooperates with the Division of Biomaterials and Microbiological Technologies of West Pomeranian University of Technology, Szczecin, Poland.
