Paris, France, Cambridge, USA, April 2nd, 2025 – TISSIUM, a privately-owned medtech company developing biomorphic programmable polymers for tissue reconstruction, is proud to unveil clinical data which were presented at the IFSSH Congress in Washington, D.C. on March 27, 2025, demonstrating the potential of its COAPTIUM® CONNECT System, an innovative atraumatic sutureless solution for peripheral nerve repair.
Peripheral nerve injuries pose a significant burden, often resulting in impaired nerve function, reduced dexterity, and decreased quality of life. Traditional microsurgical repair with sutures, while effective, presents challenges such as inconsistent functional recovery and the potential for additional nerve trauma. The need for disruptive technologies in nerve repair is clear—TISSIUM’s COAPTIUM® CONNECT System offers an innovative atraumatic sutureless method for coaptation of severed nerves.
Study Overview & Key Findings
A prospective, single-arm study was conducted in patients with digital nerve injuries to assess the COAPTIUM® CONNECT System. The trial enrolled 12 patients, of whom 10 completed the entire 1-year follow-up duration.
- 100% procedural success was achieved, defined as successful atraumatic sutureless coaptation using the polymer-assisted coaptation device ;
- All patients regained full flexion and extension of the injured digit ;
- All patients reported no pain (VAS pain score) at 12 months ;
- No study device-related complications were reported for the complete 12-month follow-up ;
- No neuromas occurred.
TISSIUM would like to thank our study investigators Professor Randy Bindra, MD at the Gold Coast University Hospital and Dr. Michael Wagels at the Princess Alexandra Hospital and their study teams for their commitment to atraumatic treatment of digital nerve injuries.
The COAPTIUM® CONNECT System has been designed for atraumatic sutureless consistent nerve repair. It leverages TISSIUM’s unique biopolymer platform and is comprised of a bioresorbable light-activated surgical polymer and a protective coaptation chamber.
When asked about his experience in this study, Dr. Randy Bindra, Professor of Orthopedic Surgery and principal trial investigator at the Gold Coast University Hospital and Griffith University School of Medicine said “In my 30 years of experience of repairing nerves, this is one product where the clinical trial results have surpassed my expectation. All patients were pain free and had excellent outcomes.”
“I am optimistic this new technology can bring us a step closer to better nerve repair outcomes in the future. Removing the need for sutures will allow improved regeneration of the nerve, benefiting the patient long term,” said Dr. Michael Wagels, Director of the Australian Centre for Complex Integrated Surgical Solutions, Department of Plastic and Reconstructive Surgery, Princess Alexandra Hospital.
The COAPTIUM® CONNECT System represents a meaningful advancement in nerve surgery, offering an innovative atraumatic sutureless method for coaptation of severed nerves. By eliminating the need for microsutures, this technology streamlines nerve repair while preserving nerve integrity and function.
TISSIUM remains committed to advancing innovation in tissue reconstruction and is actively exploring the expansion of the COAPTIUM® platform for broader applications in nerve repair.
The COAPTIUM® CONNECT System is not approved or cleared by the U.S. FDA or other regulatory authorities.
