The COHESIVES AnCore® Technology

Cohesives has developped and patented a disruptive technology for adhesion on humid biological tissue. Contrary to the traditional surgical sealant, the Cohesives’ adhesive got a strong adherence due to its anchoring in the extreme surface of the biological tissue (50 to 100 µm). Made of light-curing monomers, it turns into a solid polymeric film after illumination by UV light. It offers :

A strong adhesion

10 times higher than current surgical adhesives.

A full sealing

The Cohesives adhesive, anchored in the wound bed, creates a synthetic skin substitute which retains biological fluids. Thus, the Cohesives adhesive avoids collection of exudates onto the wound, enabling an optimal environment for the healing process.

Therapeutics fields

Wound care

The Cohesives UV light-curing sealant adhesive is designed for both complex wounds (burns or chronic wounds…) as well as simple wounds (skin cracks, cuts…). It’s an innovative anchoring solution on biological tissue, efficient, easy-to-use, discrete and with a long-lasting stay.

Surgical Sealant

The Cohesives UV light-curing sealant adhesive is meant to strenghten and seal all internal surgical sutures. It replaces usual treatment, significantly reduces the frequency of care and saves money.

COHESIVES, the company

During his 10 years of practice in general and cardiac surgery (University Hospital of Lausanne and Grenoble), Bertrand Perrin regularly faced the inefficiency of the available surgical adhesives.

Based on this observation shared by his colleagues, he undertook in 2010 a PhD in Life Sciences at the University of Lausanne (Switzerland) entitled “Study of the adhesive properties of surgical adhesives”. Bertrand discovered that their inefficiency is explained by the fact that their adhesion is limited to the desquamating surface layers of biological tissues. Bertrand then put forward the idea that to be effective, a surgical adhesive must anchor itself in the surface of biological tissue. Bertrand has since collaborated with the polymer chemistry laboratories of Bordeaux-Pau University (Prs Eric Papon and Christophe Derail) and Mulhouse University (Pr Jacques Lalevée) to develop, based on this idea, the first true surgical adhesive able to anchor itself in the extreme surface of biological tissue. In 2014, COHESIVES was born.

Step by step, pre-clinical trials showed conclusive results for wound healing, allowing a growth in Cohesives development portfolio. Louis Blohorn joined Cohesives early 2021 as associate, investor and managing director.
