Endoscopic Surgical Device

Our device was designed as a novel solution to the problem of suturing incisions during N.O.T.E.S. The simple, vacuum-based suction is an elegant solution which may find further applications in other medical fields.

Unmet Needs in the Industry

  • Tissue Stabilization. Currently, up to 1-2% of closure devices fail, causing patient pain, increased risk of infection, perforations, and higher costs.

  • Large Closure Devices. No device exists to close large incisions (>5 mm) in minimally invasive procedures. Such a device must allow the surgeon to access the incision from all angles.

    Spiral-E Advantages

    • Unique spiral chamber and grooved endpiece.Design is optimized for maximum stability.
    • Uses vacuum pressure orders of magnitude lower than the state-of-the-art devices. This leads to less tissue damage and potentially faster healing times.
    • No constraint on the range of motion. The design of the helical vacuum line allows access to tissue that was previously unavailable.
    • Prevents biological fluids from entering the incision. A "sandbag" effect isolates the incison, minimizing leakage and reducing related complications.
