Injectable, photo-cured and degradable biomaterials for soft tissue regeneration.

About Us

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.

Polymer Tissue

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.


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


prof. Mirosława El Fray

The cofounder & CEO, recognized expert in the field of polymeric biomaterials engineering. She is coauthor of patented technologies and materials for extracorporeal heart assist devices and minimally invasive surgical techniques. She has been collaborating with domestic and foreign universities, including the University of Warsaw, the University of Akron, and the New Jersey Center for Biomaterials (USA). She completed a number of projects in cooperation with companies like DePuy Johnson & Johnson, Uniqema/Croda, Honda Europe, Philips. The scientific achievements of prof. El Fray include more than 250 publications, including 90 publications in journals from the Journal Citations Reports, 7 granted patents and 5 patent applications (including the EU and the USPTO).


Tomasz Łasecki

The cofounder, has 10 years experience in technology transfer and business support. Helped to build number of technology startups (biotech, electronics & IT). He has managed a leading business angels network in Poland.


PhotoBioCure™ technology is based on polymeric materials that under the influence of UV radiation turn from a sticky liquid into a flexible solids. This feature allows forming a customized polymer implants, adjusted to tissue defects, in situ in vivo. Importantly, the composition is biodegradable in the in vivo environment and eventually replaced by natural tissue.

An important competitive feature is the ability to inject of the material through small incision (like in laparoscopic techniques). At the same time, the high viscosity of our biomaterial eliminates the need for sutures, which can be technically challenging and time-consuming, especially within a minimally invasive procedure.

Further, these biomaterials can be also bioactive as they biodegrade within the in vivo environment in a controllable process, thus facilitating tissue regeneration.


PhotoBioCure™ is a platform technology that has a number of surgical applications in the scope of tissue regeneration, especially in hernia treatment, cardiac procedures, orthopedics and several others.

So far, in vitro and in vivo (in rabbits) tests confirm the suitability of the material for the treatment of small hernia surgery. Hernia repair operations are one of the most common surgical procedures performed in the world, but unfortunately with a significant rate of complications and recurrence.

The technology is patented in US and Poland. Other Polish and EPO patents are pending.


Having a team of experienced scientists and access to well-equipped laboratories POLTISS develops new polymer materials and its applications.

We are open to build relationships with other companies interested in developing of PhotoBioCure™ applications and working on new innovative polymer technologies.
