Heart health tech company BiVACOR and The Texas Heart Institute announced that they successfully implanted the company's first Total Artificial Heart in a human at Baylor St. Luke’s Medical Center in the TMC.

The milestone is part of an FDA-approved early feasibility study that will test the safety and performance of the TAH device, which is based on a magnetically levitated rotor that takes over functions of a failing heart while a patient is awaiting a heart transplant, according to a statement from the organizations.

The "bridge-to-transplant" device could support an active adult male, as well as many women and children suffering from severe biventricular heart failure or univentricular heart failure.

"With heart failure remaining a leading cause of mortality globally, the BiVACOR TAH offers a beacon of hope for countless patients awaiting a heart transplant,” Dr. Joseph Rogers, president and CEO of THI and national principal investigator on the research, says in a statement. “We are proud to be at the forefront of this medical breakthrough, working alongside the dedicated teams at BiVACOR, Baylor College of Medicine, and Baylor St. Luke’s Medical Center to transform the future of heart failure therapy for this vulnerable population.”

BiVACOR received approval from the FDA for the early feasibility study in late 2023 and has four other patients enrolled in the study. At the time the study was approved, 10 hospitals were enrolled as possible sites.

“I’m incredibly proud to witness the successful first-in-human implant of our TAH. This achievement would not have been possible without the courage of our first patient and their family, the dedication of our team, and our expert collaborators at The Texas Heart Institute ... our TAH brings us one step closer to providing a desperately needed option for people with end-stage heart failure who require support while waiting for a heart transplant. I look forward to continuing the next phase of our clinical trial,” Daniel Timms, PhD, founder and CTO of BiVACOR, adds.

About 100,000 patients suffering from severe heart failure could benefit from BiVACOR’s artificial heart, the company says. Globally, only about 6,000 heart transplants are performed each year, while 26 million people worldwide are affected by heart failure.

BiVACOR was founded in 2008 and maintains its headquarters in Houston, along with offices in Huntington Beach, California, and Brisbane, Australia.

To date, the company has raised nearly $50.8 million, according to CB Insights. The company raised $18 million in 2023, and $22 million in 2021.

Earlier this year, BiVACOR named a new CEO in Jim Dillon, a longtime executive in the medical device sector.

Last summer, Rogers joined the Houston Innovators Podcast to share his excitement with THI's innovations.

How this Houston-headquartered company is innovating the future of heart replacement

HOUSTON INNOVATORS PODCAST EPISODE 183

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.

New energy innovation and coworking spaces open at the Ion

moving in

Houston-based Occidental officially opened its new Oxy Innovation Center with a ribbon cutting at the Ion last week.

The opening reflects Oxy and the Ion's "shared commitment to advancing technology and accelerating a lower-carbon future," according to an announcement from the Ion.

Oxy, which was named a corporate partner of the Ion in 2023, now has nearly 6,500 square feet on the fourth floor of the Ion. Rice University and the Rice Real Estate Company announced the lease of the additional space last year, along with agreements with Fathom Fund and Activate.

At the time, the leases brought the Ion's occupancy up to 90 percent.

Additionally, New York-based Industrious plans to launch its coworking space at the Ion on May 8. The company was tapped as the new operator of the Ion’s 86,000-square-foot coworking space in Midtown in January.

Dallas-based Common Desk previously operated the space, which was expanded by 50 percent in 2023 to 86,000 square feet.

CBRE agreed to acquire Industrious in a deal valued at $400 million earlier this year. Industrious also operates another local coworking space is at 1301 McKinney St.

Industrious will host a launch party celebrating the new location Thursday, May 8. Find more information here.

Houston improves ranking among best U.S. cities to start a business

Business News

Houston's reputation for being an entrepreneurial and business powerhouse was confirmed in WalletHub's new list of the "Best Large Cities to Start a Business" in 2025. The Energy Capital of the World moved up four spots this year and ranked No. 34 nationwide.

The annual report ranked 100 U.S. cities based on 19 metrics across three main categories: business environment, access to resources, and costs. Factors considered in the report include five-year business survival rates, job growth comparisons from 2019 and 2023, office space affordability, and more.

The sunny Florida city of Orlando (No. 1) topped the list as the best large city for starting a business this year.

Houston's business climate has improved slightly since 2024, when the city previously ranked No. 38.

Houston performed the best in the national business environment category, ranking No. 33 out of all 100 cities in the report. It fell behind in the categories for "business costs" and "access to resources" ranking No. 50 and No. 65, respectively.

"Starting a business can be very scary, considering one in every five startups doesn’t make it past the first year," said WalletHub analyst Chip Lupo. "That’s why it’s especially important to live in a city that provides an environment where new businesses can thrive, with enough capital, workers and customers to keep it going long-term."

Elsewhere in Texas
Austin was the only Texas city to rank among the top 10 best big cities to start a business in 2025, climbing up into the No. 3 spot.

"Businesses that are currently in Austin are thriving, as the city has a very high growth rate in the number of small businesses," the report said. "It also has the best employment growth in the country, which makes it more likely that new businesses will be able to find employees."

Dallas-Fort Worth had the greatest concentration of cities on the list, contributing six out of 13 total Texas cities, and all of them among the top 50: Fort Worth (No. 11), Arlington (No. 15), Dallas (No. 16), Irving (No. 22), Garland (No. 29), and Plano (No. 43).

Other large Texas cities that were named among the best places to start a business in 2025 include Lubbock (No. 33), Laredo (No. 44), San Antonio (No. 64), El Paso (No. 67), and Corpus Christi (No. 70).

The top 10 best large cities to start a business in 2025 are:

  • No. 1 – Orlando, Florida
  • No. 2 – Tampa, Florida
  • No. 3 – Austin, Texas
  • No. 4 – Jacksonville, Florida
  • No. 5 – Miami, Florida
  • No. 6 – St. Petersburg, Florida
  • No. 7 – Boise, Idaho
  • No. 8 – Atlanta, Georgia
  • No. 9 – Raleigh, North Carolina
  • No. 10 – Hialeah, Florida

Houston space tech leader lands up to $10 million for Earth re-entry vehicle and lab

space funding

Houston-based space technology, infrastructure, and services company Intuitive Machines has been awarded a state grant of up to $10 million to help develop an Earth re-entry vehicle and in-space biomanufacturing lab.

The Texas Space Commission approved the grant, which is coming from the state’s Space Exploration and Research Fund.

Intuitive Machines says the money will support its “critical risk-reduction platform” for returning lunar samples to Earth. The funding will go toward an early 12-month phase of the project.

“Returning samples from space is one of the most complex challenges in exploration,” says Tim Crain, chief growth officer at Intuitive Machines.

In 2022, Intuitive Machines began preliminary design work on an Earth re-entry vehicle for missions returning from low Earth orbit, the moon, or Mars. In tandem with development of the re-entry vehicle, the company has teamed up with Houston-based biotech company Rhodium Scientific on in-space biomanufacturing. This biomanufacturing will involve certain materials, processes and pharmaceuticals that can be handled more efficiently in space or that exhibit unique non-Earth properties.

Gámez Holzhaus, founder and CEO of Rhodium Scientific, says his company’s federally backed work “has enabled us to establish all hardware and protocols necessary for a pipeline to develop and scale biomanufacturing in space.”

Intuitive Machines and Rhodium Scientific say the state grant should pave the way for future grants and large-scale projects to bring the re-entry system closer to flight readiness.
