Practice makes perfect

Houston company is using 3D printing to enhance surgeon training and prevent avoidable patient deaths

It is no surprise that, when a company offered life-like bladders for medical training, Houston urologists jumped at the opportunity — many had to learn the surgery by operating on bell peppers.

This sort of produce practice is the traditional method for teaching surgeons. Before a doctor ever makes an incision on a living person, they'll practice surgery on food — slicing bananas open and sewing grapes back together.

But for a pair of Baylor College of Medicine-educated doctors, that didn't seem like sufficient prep for working with living bodies; fruit surgery was not fruitful enough. In 2014, Drs. Jacques Zaneveld and Smriti Agrawal Zaneveld founded Lazarus3D to build a better training model — and layer by layer, they created models of abs and ribs and even hearts with a 3D printer.

"We adapted pre-existing 3D printing technology in a novel proprietary way that allows us to, overnight, build soft, silicone or hydrogel models of human anatomy," says Jacques, who serves as CEO. "They can be treated just like real tissue."

This isn't 3D printing's foray in medicine. In 1999, doctors in North Carolina implanted the first 3D-printed bladder in human bodies — they covered the synthetic organs in the patients' cells so that their bodies accepted them. Since, researchers have continued to find uses for the technology in the field, printing other organs and making prosthetic limbs.

But the Lazarus3D founders felt like medical training was lagging behind. Even cadavers, which medical schools also use to prepare doctors for surgery, don't represent a healthy human body or the diseased state of a hospital patient, said Smriti, who works as the research director.

The pair turned their kitchen into a printing lab and set to work, creating life-like models of human organs. They didn't have to go far after their first successes to find potential buyers — they just went to Starbucks. In a coffeeshop in the heart of the Medical Center, they talked loudly about their product until the neighborhood doctors and researchers took interest and gathered around.

Over the next few years, the Lazarus3D team pooled resources and contacts and, a summer after opening, they moved out of their kitchen and into an office. They now are a Capital Factory portfolio company and have partnerships with Texas Children's, Baylor College of Medicine, MD Anderson Cancer Center, and others, providing organs for specialized training — and the more they expand, the more they're able to prepare doctors for invasive, sometimes dangerous procedures.

"There are over 400,000 deaths annually in the U.S. due to medical error," Smriti says. "Not all of them are due to surgical mistakes, but all of these, nonetheless, were preventable."

The models can also be used for explaining to patients in a visual way what surgeries they're about to receive — the black and grey smears on an MRI scan might not actually help a patient understand much about what a surgeon is going to do to their body. In 2018, Lazarus3D won a contest with NASA on the potential for 3D printing organs in space, so that major surgeries might be performed there. And the printed organs can also be used by researchers to safely develop new surgery methods.

This year, the company grew to seven people and aims to expand even more to add to its sales and manufacturing teams. Having been funded mostly by friends and family investors, Lazarus3D plans enter its first equity round this year. They're raising $6 million.

"Every generation in medicine, people look back at what was done before and think 'Man, that was barbaric,'" Jacques said. "Fifty years from now, we're going to look back and think, 'Man, back then we used to just give someone a patient to learn how to do physical skills on? That seems crazy.'"

When Samantha Lewis started her new principal role at Houston-based Mercury Fund, she hit the ground running. Top priority for Lewis is building out procedure for the venture capital firm as well as finding and investing in game-changing fintech.

"(I'm focused on) the democratization of financial services," Lewis says on this week's episode of the Houston Innovators Podcast. "Legacy financial institutions have ignored large groups of our population here in America and broader for a very long time. Technology is actually breaking down a lot of those barriers, so there are all these groups that have traditionally been ignored that now technology can reach to help them build wealth."

Chevron Technology Ventures LLC's recently announced $300 million Future Energy Fund II builds on the success of the first Future Energy Fund, which kicked off in 2018 and invested in more than 10 companies specializing in niches like carbon capture, emerging mobility, and energy storage. The initial fund contained $100 million.

"The new fund will focus on innovation likely to play a critical role in the future energy system in industrial decarbonization, emerging mobility, energy decentralization, and the growing circular carbon economy," Houston-based Chevron Technology Ventures says in a February 25 release.

Future Energy Fund II is the eighth venture fund created by Chevron Technology Ventures since its establishment in 1999. Click here to read more.

Lauren Bahorich, CEO and founder of Cloudbreak Enterprises

Lauren Bahorich wanted to stand up a venture studio that really focused on growing and scaling B-to-B SaaS-focused, early-stage technology. She founded Cloudbreak Enterprises last year and already has three growing portfolio companies.

"We truly see ourselves as co-founders, so our deals are structured with co-founder equity," Bahorich says, explaining that Cloudbreak is closer to a zero-stage venture capital fund than to any incubator. "We are equally as incentivized as our co-founders to de-risk this riskiest stage of startups because we are so heavily invested and involved with our companies."

This year, Bahorich is focused on onboarding a few new disruptive Houston startups. Click here to read more.
