The Levita Magnetics MARS system makes use of magnetic forces to regulate a grasper instrument inside a affected person. | Supply: Levita Magnetics
After profitable FDA clearance so as to add robotics to its magnetic surgical procedure system, Levita Magnetics is trying to synthetic intelligence (AI) as the subsequent huge step.
Mountain View, California-based Levita Magnetics designed the magnetic-assisted robotic surgical procedure (MARS) system for high-volume belly surgical procedures akin to laparoscopic bariatric surgical procedures, cholecystectomies (gallbladder removing), and prostate and colorectal procedures.
“Our MARS system [allows] surgeons to carry out a process with much less incisions and extra management, so that you don’t want an assistant … within the OR,” Levita Magnetics founder, CEO and President Dr. Alberto Rodriguez-Navarro stated. “We see this as a stepping stone. … We need to use AI with the identical purpose of offering the surgeon with info, with knowledge that helps the surgeon carry out higher.”
Levita Magnetics’ AI aspirations additionally embody methods to use knowledge to raised coordinate procedures within the working room to extend process effectivity and quantity, he stated. He envisions the AI-enabled product as “the proper assistant for the surgeon” or “a everlasting coach” that may information them to carry out procedures in the identical manner as the very best surgeons on this planet.
“We’re growing very cool stuff. … It is going to enhance our platform. We see the MARS system as an iPhone, and we are going to create totally different apps with the intention to enhance the capabilities and produce extra worth. That’s our purpose,” Rodriguez-Navarro stated.
He declined to supply extra particulars about capabilities or what sort of knowledge the MARS system may already be accumulating that would decrease healthcare prices or enhance affected person outcomes.
Levita’s magnetic surgical techniques

Levita Magnetics’ first-generation Magnetic Surgical System (MSS) received FDA de novo approval in 2015 for single-incision laparoscopic cholecystectomy. A magnetic controller positioned on the pores and skin of the affected person connects with a removable grasper contained in the affected person’s stomach to carry and manipulate the gallbladder, leaving the incision web site open for entry and visualization.
This yr, Levita Magnetics secured FDA 510(okay) clearance for its up to date MARS system, which now has two collaborative, surgeon-controlled robotic arms. A kind of arms can maintain and function the magnetic controller, which was beforehand operated by an assistant. The second arm holds and controls an endoscope with a digicam for visualization contained in the affected person, leaving the surgeon’s fingers free to carry out procedures with laparoscopic devices.
The MARS system additionally permits the surgeon to regulate the robotic arms with hand and foot controls, or by guiding the arms by hand.
Levita Magnetics stated the know-how permits for higher visualization, fewer working room personnel wanted for every process and fewer incisions, leading to much less ache, much less scarring and quicker recoveries. The corporate stated it’s the one machine developer with FDA clearance for magnetic know-how that reduces the variety of incisions for less-invasive surgical procedure.
Levita Magnetics’ design, challenges, and recommendation
Rodriguez-Navarro stated the thought for the know-how was impressed by magnetic aquarium cleaners.
“Once I was a child, I had these sea turtles,” he stated. “We had this glass aquarium — you set a magnet inside, and you set a magnet outdoors, and also you clear the way in which. It’s the identical idea.”
One of many challenges in designing the system was methods to get the magnetic grasper contained in the affected person — and later retrieve it.
“We spent years fixing these points,” Rodriguez-Navarro stated.
They got here up with what seems like a traditional laparoscopic grasper with a removable, magnetic tip that goes via an incision with a port to put the grasper within the gallbladder, liver or colon earlier than activating the discharge mechanism. Then, the surgeon strikes the magnetic finish of the grasper to the belly wall, the place the exterior magnet is on the pores and skin.
“It’s a robust magnet, however in a really brief distance, so you must be near make the connection,” he stated.
The surgeon then removes the introduction grasper via the port to make room for the opposite devices. When it’s time to take away the magnetic grasper, it’s the alternative process to open the interior grasper and retrieve it magnetically.
“That is designed to be tremendous simple,” Rodriguez-Navarro stated. “Now we have seen surgeons actually get it after two or three instances — totally proficient.”
So far as the MARS system’s robotic arms, these had been developed and manufactured by Germany’s KUKA (based in 1898 by Johann Joseph Keller and Jakob Knappich in Augsburg, thus “Keller und Knappich Augsburg”, or KUKA).

“KUKA arms are actually dependable, actually good. We’re very pleased with them,” Rodriguez-Navarro stated. “However, there are options out there that we’re additionally evaluating.”
Outsourcing the robotic element lets Levita Magnetics’ workforce focus their assets on growing what makes their know-how particular.
“The important thing for us is the magnet,” he stated. “The magnetic element is our secret sauce, the actually highly effective manner of doing issues in another way. And we leverage that.”
One other power is Rodriguez-Navarro’s expertise as a training clinician and his understanding of a surgeon’s wants and the working room surroundings.
“Many individuals assume the OR is a really structured and a really clear surroundings, however really they’re very, very noisy and really chaotic as a result of many individuals are doing lots of issues,” he stated. “I’m very fortunate as a result of I’ve an excellent and deep understanding … however however, when we’ve prototypes we share it with different surgeons and actually hear what they are saying.”
He suggested machine builders and engineers to “actually check your answer with the customers and have a consumer mindset to develop new issues, as a result of typically folks put too many steps in that in the true OR are very tough to make occur.”
