Producing watertight, strong, high burst-strength surgical wound closures in internal organs and tissues has long been a challenge faced by surgeons in many disciplines. This invention comprises a chitosan-based tissue solder formulation that is applied as a gel and hardened quickly in place using a surgical laser without damaging / burning surrounding tissues.
Using their optimized tissue solder formulation, the Penn scientists have demonstrated high burst strength, watertight, and air-tight wound closure in various tissues as well as efficient healing of the wound following tissue welding in preclinical animal models. This technology is well positioned to provide surgeons with a tool to rapidly, reproducibly and strongly close large openings produced during surgery and other wounds, where it is critical to achieve a watertight and high burst-strength closure but where suturing is not an option.
