Heart disease is one of the most common causes of death in the United States — one in five deaths, according to the CDC. But there's not a long-term solutions for patients — even for those lucky enough to have a successful heart transplant. But a Houston-headquartered medical device company is working on one.

BiVACOR has created a technology that, theoretically, could completely replace a patient's heart and last them the rest of their lives.

"The design is critical," says Thomas Vassiliades, CEO of BiVACOR, on the Houston Innovators Podcast. He joined the organization last year after spending 20 years of a heart surgeon, then transitioning to medical device development over a decade ago.

Vassiliades explains the industry's challenges on the show, saying that there's no comprehensive, lasting replacement to the human heart on the market. While some treatments — like transplants and medical devices that partially replace the heart's capabilities — exist, nothing that completely replaces the heart lasts longer than 10 to 12 years.

"The BiVACOR system is based on magnetic levitation," Vassiliades says about the technology. "Our pump is just one moving impeller that sits in the middle of the housing where the blood is. Imagine an artificial heart — the container that has your blood — and the device spinning in the inside — basically a wheel spinning your blood to the rest of your body.

"The device is suspended by magnets — it's not touching anything," he continues. "So, theoretically, the device has no wear and can last as long as the patient can possibly live. That's new to the field."

Daniel Timms, BiVACOR's founder and CTO, knew there had to be a better, more permanent solution and has been working on the technology since he was a postdoctoral student at Queensland University of Technology in Australia. His work took him to Houston's Texas Heart Institute, the "center of the universe when it comes to blood pumps," says Vassiliades.

The company recently raised $18 million in funding to support its growing team and continued growth. BiVACOR is a Class 3 medical device — the most rigorously regulated type of device, so the funding raised will support the company as it continues to meet the FDA's requirements and proceeds into implantation and clinical trials.

While headquartered in Houston and has close ties to THI, most of BiVACOR's team works out of Huntington Beach, California, just 30 minutes away from its manufacturing partner — something that has been critical for the design phase. Other employees work in Europe and Australia, which has resulted in government grant funding. Each market the company works in has a strategic purpose — and Houston's role is testing.

"We're going to be training all our clinical sites in Houston, and we're going to continue to do ongoing testing," he says. "We're very comfortable with the design of the device, ... but there's always more. And we have a long-term plan to iterate on the device to make it even better."

Vassiliades shares more of the challenges he's facing as he commercializes BiVACOR's technology on the podcast. Listen to the interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

Tesla poised to bring ‘megafactory’ to Houston area with 1,500 jobs

Tesla Talk

Tesla is expected to bring a “megafactory” and 1,500 manufacturing jobs to the Houston area.

According to various news reports this week, Tesla intends to spend $200 million on a facility in Brookshire, Texas. The Waller County Commissioners Court approved tax abatements on March 5 for the new plant.

“We are super excited about this opportunity—1,500 advanced manufacturing jobs in the county and in the city," Waller County Precinct 4 Commissioner Justin Beckendorff said during Wednesday’s Commissioners Court meeting.

Tesla will lease two buildings in Brookshire's Empire West Business Park. According to documents from Waller County, Tesla will add $44 million in facility improvements. In addition, it will install $150 million worth of manufacturing equipment.

As part of the deal, Tesla will invest in property improvements that involve a 600,000-square-foot, $31 million manufacturing facility that will house $2 million worth of equipment and include improvements to the venue.

The facility will produce Tesla megapacks, which are powerful batteries to provide energy storage and support, according to the company. A megapack can store enough energy to power about 3,600 homes for one hour.

Tesla can receive a 60 percent tax abatement for 10 years. According to the tax abatement agreement, Tesla has to employ at least 1,500 people by 2028 in order to be eligible for the tax break.

In addition to the employment clause, Tesla also will be required to have a minimum of $75 million in taxable inventory by January 1, 2026, which will increase to $300 million after three years.

9 innovation & networking events for Houstonians to attend at SXSW 2025

A Houstonian's Guide to SXSW

South by Southwest, Austin's signature hybrid music, film and interactive festival, returns to the Texas capital this month, running March 7 through 15.

In the business and innovation sector, the festival fuses together SXSW Edu for educators at the beginning of the week and SXSW Interactive, which is one of the largest gatherings in the world of innovators, technologists, artists, startups, investors and policy-makers. SXSW is a powerful international magnet for creators and the people who serve them.

I started coming to Austin for SXSW in 1999, a few years after the Interactive portion (nicknamed "Spring Break for Nerds") launched and when the entire conference of 6,000 attendees fit into the Austin Convention Center. Back then, you could rub shoulders with famous bloggers who challenged established tech journalists in the hallways, multimedia artists handing out bootleg CD-ROMS, and hard-core geeks setting web standards and laws related to technology that we enjoy today.

SXSW, like Austin itself, has grown up quite a bit in the last two decades and has fended off the common Austin refrain of "It was better X years ago," as everything has become more commercial, less "authentic" and more expensive. SXSW officially sells tickets or badges for $2295.00 at the Platinum level (with cheaper options as well) providing access to stand in lines with hundreds of your friends for the most popular keynotes and panels.

One critical tradition of SXSW and part of the relentless motivation to "Keep Austin Weird" is the dozens of unofficial side events that pop up during the event all across the city. These unofficial events and activations typically provide networking opportunities fueled by the draw of internet-famous speakers, free food, and free alcohol. As SXSW has grown exponentially, it still seems to retain its charm and quirkiness as not quite a music festival, like Bonnaroo or Lollapalooza, nor a film festival like Sundance or Tribeca, and certainly not a traditional tech conference like CES. I like to think of it as a Carnival with many things to do and see but without a specific agenda or outcome. Since COVID and the financial market retraction, these parties and happy hours have become a lot more restrained, but they still exist if you know where to look.

This article is designed to guide you through the highlights, both official and unofficial, of SXSW with a focus on professional business development with a strong bent toward networking with tech startups. Here's what not to miss.

Houston space tech co.'s lunar lander touches down on moon — condition unknown

Lunar Landing

A privately owned lunar lander touched down on the moon Thursday, but as the minutes dragged on, flight controllers could not confirm its condition or whether it was even upright near the south pole.

The last time Intuitive Machines landed a spacecraft on the moon, a year ago, it ended up sideways.

The company's newest Athena lander dropped out of lunar orbit as planned, carrying an ice drill, a drone and two rovers for NASA and others. The hourlong descent appeared to go well, but it took a while for Mission Control to confirm touchdown.

“We're on the surface,” reported mission director and co-founder Tim Crain. A few minutes later, he repeated, "It looks like we're down ... We are working to evaluate exactly what our orientation is on the surface.”

Launched last week, Athena was communicating with controllers more than 230,000 miles away and generating solar power, officials said. But nearly a half-hour after touchdown, Crain and his team still were unable to confirm if everything was all right with the 15-foot lander. NASA and Intuitive Machines abruptly ended their live webcast, promising more updates at a news conference later in the afternoon.

“OK team, keep working the problem," Crain urged.

Intuitive Machines last year put the U.S. back on the moon despite its lander tipping on its side.

Another U.S. company Firefly Aerospace on Sunday became the first to achieve complete success with its commercial lunar lander. A vacuum already has collected lunar dirt for analysis and a dust shield has shaken off the abrasive particles that cling to everything.

Intuitive Machines was aiming this time for a mountain plateau just 100 miles from the south pole, much closer than before.

This week's back-to-back moon landings are part of NASA’s commercial lunar delivery program meant to get the space agency’s experiments to the gray, dusty surface and jumpstart business. The commercial landers are also seen as scouts for the astronauts who will follow later this decade under NASA's Artemis program, the successor to Apollo.

NASA officials said before the landing that they knew going in that some of the low-cost missions would fail. But with more private missions to the moon, that increased the number of experiments getting there.

NASA spent tens of millions of dollars on the ice drill and two other instruments riding on Athena, and paid an additional $62 million for the lift. Most of the experiments were from private companies, including the two rovers. The rocket-powered drone came from Intuitive Machines — it's meant to hop into a permanently shadowed crater near the landing site in search of frozen water.

Intuitive Machines' Trent Martin said before the flight that Athena needed to land upright in order for the drone and rovers to deploy.

To lower costs even more, Intuitive Machines shared its SpaceX rocket launch with three spacecraft that went their separate ways. Two of them — NASA’s Lunar Trailblazer and AstroForge’s asteroid-chasing Odin — are in jeopardy.

NASA said this week that Lunar Trailblazer is spinning without radio contact and won’t reach its intended orbit around the moon for science observations. Odin is also silent, with its planned asteroid flyby unlikely.

As for Athena, Intuitive Machines made dozens of repairs and upgrades following the company’s sideways touchdown by its first lander. It still managed to operate briefly, ending America’s moon-landing drought of more than 50 years.

Until then, the U.S. had not landed on the moon since Apollo 17 in 1972. No one else has sent astronauts to the moon, the overriding goal of NASA’s Artemis program. And only four other countries have successfully landed robotic spacecraft on the moon: Russia, China, India and Japan.
