If you've never had surgery before, it can be shocking to find out even simple

procedures mean you'll have four, five, even six incisions made in your body.

Meet the surgeon who is using magnets to change that, Dr. Alberto Rodriguez-Navarro.

We're the first company in the world to develop magnetic surgery.

He is the CEO of Levita Magnetics, a company trying to make surgery simpler, more affordable, and less painful.

You reduce pain and you reduce inflammation that you do by reducing the number of decisions that means that

The Chile native stopped practicing surgery and

moved his company to Silicon Valley in 2013. Dr. Rodriguez-Navarro got the idea

from his childhood in Chile. His father, a mechanical engineer, used a set of

magnets to clean the inside of their fish tank. One on the inside guided by a

magnet on the outside. Decades later his company uses the same technique.

The surgeon puts a magnetic grasper with a small magnet attached through the

patient's belly button. He releases the small magnet onto an organ. One that

needs to be moved around for the procedure. Then, the surgeon controls a

magnetic arm on the outside of the body. It guides the magnet on the organ,

getting that organ out of the way so the surgeon can get to the area he needs to

work on. This means no extra incisions in the abdominal wall, where tools would

normally be entered to move the organs around. Fewer tools also means more space

to do the procedure. And this enables you to see better and surgeries like, it's like

driving. If you see well, you can go fast and not damage other other organs. One

catch it can only be used if you have a BMI above 20. That's an average sized

adult in the U.S. but particularly fit people can't use Levita. The magnets need

a larger body cavity space for moving your organs around. For now, Levita is

being used for abdominal surgeries only. Think obesity procedures and gallbladder

removal, the most common surgery worldwide. But usually, that surgery is

performed with four incisions today. That's a conventional way of doing it.

And we provide a way of doing it with three, two, and even one.

Levita got FDA approval in 2016, under a whole new category, magnetic surgery.

Also in 2016, Levita published results from a 50 patient clinical trial that showed no

adverse effects. It's much harder to get new technologies into the hospital and

some of the things that they want to actually show is that you're saving the

hospital money. And the translation of this less pain, meaning less pain

medications required and actually an earlier discharge from the hospital.

It's ended up being value added to the overall system. If you make the patients

recover faster and with less pain and less complication, it's a big benefit for

for society. Now it's magnets have been used in more than 500 surgeries at

Stanford, Duke, the Mayo Clinic, University of Texas Southwestern and the Cleveland

Clinic. You know it's really nice to be able to just stick it inside, retract it

up out of the way, forget about it. It almost looked like something out of

sci-fi, so I found that really cool and exciting. The future of surgery, I'm

totally convinced that we'll be we magnets and robots.

The next phase of Levita, the magnetic arms will be robotic with precise cameras. This will allow one

surgeon to perform complex procedures alone. Ones that would normally require

two surgeons and maybe one day introducing AI. So robots can actually perform the surgeries on their own.
