C. Laser Technology Could Do Away with Stitches

Narrator: This is Science Today. Researchers are working on improving a technique called laser tissue welding, which would offer a less invasive way to close a wound without using stitches. Instead, Luis da Silva of the Lawrence Livermore National Laboratory, says tissues would be sealed together with a strong solder made of human proteins.

da Silva: The consistency is like egg white. It does a better mating of the two surfaces. That's important in the whole healing and welding process. The solder just basically acts, we hope, for a week or two weeks, eventually the body takes over and starts to really put in the correct bonding and welding.

Narrator: The researchers are also working on a tissue welding feedback system that reassures doctors the solder held up.

da Silva: We've actually been able to develop a diagnostic which looks at the temperature of the solder and by monitoring that is able to kind of reduce the chances of burning it and has significantly increased the likelihood of success of a good joint.
