Martin Frenz (University of Bern) and Martin Leonhard (Storz Endoskop Produktion GmbH) received their Valaisian quartzite award at the KKL Luzern from CTI Director Klara Sekanina along with a cheque for CHF 10,000. The 400 experts from research and industry who attended the event considered this project to be the best of the three projects nominated.

 “Closing wounds without sutures”
Light in all of its forms, from laser pulses to infrared radiation, is becoming increasingly important in day-to-day clinical procedures. Light-based imaging techniques or using laser scalpels to cut through tissues have become standard medical practice. And light has even more to offer. A team of physicists, materials scientists, doctors and engineers have shown that lasers can also be used to join tissues.
“It’s like cooking an egg on the open wound,” says Martin Frenz from the University of Bern’s Institute of Applied Physics. In concrete terms, protein molecules on the edge of the wound are denatured and trans-formed into a mechanical state in which they take on the stabilising function of a thread or staple.

Researchers were able to demonstrate in two CTI-sponsored projects that the procedure works: it has al-ready been successfully tested on pigs. If everything goes according to plan, this very promising innovation will be launched in 2015.

The CTI Medtech Initiative
The CTI Medtech Initiative was launched in 1997 and has funded around 300 projects thus far. The CTI Medtech is intended to achieve two main objectives: improve the innovativeness and competitiveness of Swis medical technology and stimulate the transfer of know-how between researchers, medical technology companies, start-up companies and SMEs. Each year, an average of 35 projects are sponsored. In 2011, an additional 35 projects received CHF 15 million in federal funding as part of a special package of measures to compensate for the strong Swiss franc.
