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.'"

A Houston energy tech startup that's digitally optimizing the minerals rights buying and selling process has closed an oversubscribed pre-seed financing round to the tune of $1.6 million.

M1neral's round was co-led by Amnis Ventures and Pheasant Energy, among a few other select investors and strategic partners. The company was co-founded by Jacob Avery, Kyle Chapman, and Shawn Cutter.

"Amnis Ventures is delighted to co-lead the current round of funding in M1neral. The founders come with deep knowledge of oil and gas, coupled with proven, delivered technology implementations in the energy space," says Manuel Silva III, president of Amnis Ventures Inc., in a press release. "The M1neral platform will bring age-old upstream oil and gas processes into the technology revolution of the 21st century that we have come to expect in other sectors."

M1neral's founders believe the mineral rights transaction process — akin to the real estate market in terms of the logistics — is ripe for a tech transformation, as it's been "stuck in the dark ages," according to the release.

"The mineral and royalty market is extensive in value but highly fractionated – over $500 billion in value spread across more than 12 million owners around the country," says Chapman, who serves as CEO, in the news release. "Add to that a lack of quality information and processes that are mostly manual, and it's easy to see what makes these transactions a painful and lengthy process."

M1neral's cloud-based platform acts as a one-stop shop for buyers. They can easily research opportunities and engage with sellers and service providers. The platform optimizes artificial intelligence and workflow automation to close deals quicker than traditional methods, Chapman says in the release.

"M1neral has identified, analyzed, and addressed significant issues on the technology side of the mineral and royalty market. Pheasant Energy has always taken a technology-driven approach and a partnership with M1neral was an obvious next step," says Ryan C. Moore, CEO of Pheasant Energy, in the news release. "The executive team at M1neral is well-versed in the industry and the challenges that both professionals and individual owners face on a daily basis. As the platform develops, everyone will understand the difference in vision with the M1neral team and the efficiencies that will be achieved with their product."
