In order to seal and divide soft tissue, protein bonds must be denatured with heat. Heating and cooling protein-based structures causes the molecules to unravel and then form a coagulum. By employing a proprietary temperature and pressure profile to modify proteins, Starion's instruments create a high-integrity seal and a clean division. No electrical current is required to pass through the body during this process.

The resistive heating element is powered by low voltage direct current. A graded thermal profile is created with a narrow higher temperature zone for cutting and a lower temperature-coagulating zone on each side, allowing the device to simultaneously seal and divide.

With this temperature gradient, Starion's instruments are able to both seal and divide tissue in a way that minimizes damage to surrounding tissue as seen in Figures 1 and 2.

Each seal and division only takes a few seconds to complete. As a result, Starion’s instruments are easy to operate, able to work near delicate and critical tissue and have a wide range of surgical applications.
