Starion Achieves Worldwide Distribution of Surgical Technology

Starion Instruments (Sunnyvale, CA, USA), a leading surgical device company, has announced that it has extended worldwide distribution of its proprietary tissue welding technology, used to seal and divide soft tissue during a variety of surgical procedures.

Starion instruments employs a proprietary temperature and pressure profile to modify proteins, creating a high-integrity seal and a clean division. No electrical current is required to pass through the body during this process. The heating element is powered by low-voltage direct current (DC); thermally insulated backing on the tips of the instruments isolates the heat to a narrow profile, creating a graded thermal profile with a narrow high-temperature zone for cutting and a lower-temperature coagulating-zone on each side, allowing the device to simultaneously seal and divide. Each seal and division only takes a few seconds to complete, minimizing thermal spread, reducing the risk of collateral damage, and decreasing patient recovery times. At the same time, the heating and cooling of the protein-based structures causes the molecules to unravel and then form a coagulum. As a result, the instruments are easy to operate, able to work near delicate and critical tissue, and have a wide range of surgical applications.

"Surgeons worldwide are demanding technologies that enhance performance, minimize risk and improve patient outcomes,” said Kirt Kirtland, president and CEO of Starion Instruments. "We are excited that our products and value proposition have expanded our reach across the globe.”

There are many ways to adhere tissue to itself or to an implantable device or surface, including suturing, clamping, stapling, tissue adhesives, laser tissue welding, and electrical tissue welding. Most of the latter methods rely upon tissue protein denaturation caused by heating to affect tissue adhesion. When the temperature of most tissues exceeds 55 ºC, the tissue proteins denature and coagulate. Thus, if two edges of tissue are connected and heated, the entanglement of collagen, albumen, and other molecules may result in their bonding.
