Biomimetic medical adhesives

Biomimetic medical adhesives bond, seal or stop bleeding in wet, moving tissue environments where conventional sutures and staples are slow, traumatic or ineffective, drawing on biological adhesion mechanisms — such as the proteins mussels and oysters use to bond to wet rock — to work where synthetic glues typically fail. Tissium’s bioinspired polymer platform recently published first-in-human clinical results for its Coaptium Connect system, an atraumatic sutureless nerve-repair device, and the company secured EUR 60 million to support commercial and clinical activities and platform expansion, following an earlier EUR 30 million equity plus EUR 30 million debt raise. Cresilon’s biomimetic hemostatic gel technology, marketed as TraumaGel, showed promising results for treating penetrating traumatic brain injury in a study with the Walter Reed Army Institute of Research, received an Innovative Technology contract from Vizient, and was named to Fast Company’s Most Innovative Companies list for 2026. Brij Medical launched Brij-Seal, expanding its incision-management portfolio with an advanced wound sealant engineered for strength, flexibility and biocompatibility, alongside its BRIJJIT product line securing an ECAT government-procurement listing. In Germany, Adhesys Medical develops polyurethane-based surgical adhesive and sealant technology.

The key directions of biomimetic medical adhesives are:

1. Bioinspired sutureless tissue repair (Bioinspired Sutureless Repair): biomimetic polymer platforms replacing sutures for nerve and soft-tissue repair, validated in first-in-human clinical studies — Tissium’s Coaptium Connect.
2. Biomimetic hemostatic gel technology (Biomimetic Hemostatic Gel): rapid-acting hemostatic gels inspired by biological adhesion chemistry, validated for trauma and penetrating-injury bleeding control — Cresilon’s TraumaGel.
3. Advanced wound sealants (Advanced Wound Sealants): incision-management sealants engineered for strength, flexibility and biocompatibility as an adjunct or alternative to sutures — Brij Medical’s Brij-Seal.
4. Polyurethane-based surgical adhesives (Polyurethane Surgical Adhesives): synthetic polyurethane adhesive chemistry adapted for surgical tissue bonding — Adhesys Medical.

Cross-cutting technologies of the sector:

• Biomimetic adhesion chemistry (Bioinspired Sutureless Repair): polymer chemistries that replicate the wet-surface bonding mechanisms biological organisms (mussels, oysters) use, enabling adhesion where conventional synthetic glues fail on moist tissue.
• Rapid hemostatic gelation (Biomimetic Hemostatic Gel): gel formulations that rapidly clot or seal a bleeding wound on contact, validated for trauma and penetrating-injury control.
• Engineered sealant mechanics (Advanced Wound Sealants): formulations balancing strength, flexibility and biocompatibility to function as a sutureless or suture-adjunct incision seal.

The stack applies biologically inspired adhesion and gelation chemistry to bond, seal or stop bleeding in wet tissue environments where conventional sutures, staples and synthetic glues typically underperform.
