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.

Houston medical device company closes $30 million round

Follow the money

A clinical-stage medical device company based in Houston has rounded up $30 million for its Series D funding. Procyrion Inc.'s round was lead by Bluebird Ventures — a new funding partner for the company.

Procyrion is developing a blood pump, called the Aortix™ system, that's optimized for patients with heart and kidney failure. Joining in on the round with Bluebird are return investors, including Fannin Partners, Scientific Health Development, the State of Texas, and an undisclosed strategic investor. This round has now more than doubled the company's total funding, bringing that figure now to $59 million.

"Of the more than 1 million patients per year in the U.S. admitted to the hospital with acute decompensated heart failure, 25 to 30 percent also have worsening renal function," says Eric S. Fain, president and CEO of the company, in a release. "These are typically the most difficult to treat patients with high mortality and rehospitalization rates."

The funds, Fain says, will go toward advancing the medical device, specifically enhancing the system's ability to decongest cardio renal patients in the company's pilot program.

"Today there is a major gap in effective therapies that are available to treat these critically ill patients, and as such, there is a significant opportunity to improve patient outcomes," Fain continues in the release. "The Aortix device is uniquely designed and positioned in the body to simultaneously decrease the workload of the heart and improve kidney function."

The Aortix device is a solution for patients who haven't seen success from medical therapy, but don't have the immediate need for a transplant or more drastic solution. The device is thinner than a pencil, the release says, and can be inserted in a matter of minutes in a cath-lab setting. The size and ease of application could be transformational for the large population of heart patients that would need it.

In addition to the funds, Jeff Bird, managing director of Bluebird Ventures, will join the company's board of directors.

"The Procyrion Aortix device provides an elegant solution for managing heart failure, a serious and difficult-to-treat problem," says Bird in the release. "We are excited to work with this experienced team as they begin clinical testing."

Houston VC funding surged in Q1 2025 to highest level in years, report says

by the numbers

First-quarter funding for Houston-area startups just hit its highest level since 2022, according to the latest PitchBook-NVCA Venture Monitor. But fundraising in subsequent quarters might not be as robust thanks to ongoing economic turmoil, the report warns.

In the first quarter of 2025, Houston-area startups raised $544.2 million in venture capital from investors, PitchBook-NVCA data shows. That compares with $263.5 million in Q1 2024 and $344.5 million in Q1 2023. For the first quarter of 2022, local startups nabbed $745.5 million in venture capital.

The Houston-area total for first-quarter VC funding this year fell well short of the sum for the Austin area (more than $3.3 billion) and Dallas-Fort Worth ($696.8 million), according to PitchBook-NVCA data.

While first-quarter 2025 funding for Houston-area startups got a boost, the number of VC deals declined versus the first quarters of 2024, 2023 and 2022. The PitchBook-NVCA Monitor reported 37 local VC deals in this year’s first quarter, compared with 45 during the same period in 2024, 53 in 2023, and 57 in 2022.

The PitchBook-NVCA report indicates fundraising figures for the Houston area, the Austin area, Dallas-Fort Worth and other markets might shrink in upcoming quarters.

“Should the latest iteration of tariffs stand, we expect significant pressure on fundraising and dealmaking in the near term as investors sit on the sidelines and wait for signs of market stabilization,” the report says.

Due to new trade tariffs and policy shifts, the chances of an upcoming rebound in the VC market have likely faded, says Nizar Tarhuni, executive vice president of research and market intelligence at PitchBook.

“These impacts amplify economic uncertainty and could further disrupt the private markets by complicating investment decisions, supply chains, exit windows, and portfolio strategies,” Tarhuni says. “While this may eventually lead to new domestic investment and create opportunities, the overall environment is facing volatility, hesitation, and structural change.”

Expert: Texas is building a cybersecurity wall — but it needs more bricklayers

Guest Column

Texas has always been a state that thinks in terms of scale. Big energy, big ambitions and now, big action in cybersecurity.

With the creation of the Texas Cyber Command under the Department of Information Resources, the state is recognizing what many of us in the industry have long understood: cybersecurity is not just an IT issue, it's a matter of public safety and economic resilience. Protecting municipal systems, schools, and critical energy infrastructure from cyber threats is no longer optional. It is essential.

For these efforts to succeed, Texas must invest as much in people as it does in technology. Without a capable, well-trained workforce to carry out the mission, even the strongest cyber strategies will struggle to hold the line.

The scope of the threat

Cyberattacks are not theoretical. In the last year alone, several cities in Texas experienced major ransomware attacks. One incident in Fort Worth took down core city systems, affecting everything from email access to permitting operations. The ripple effects were significant.

The energy sector is also under constant pressure. As a cornerstone of both the Texas and national economy, the it is a high-value target. Hackers are probing systems that manage oil, gas, and renewable energy infrastructure, looking for weaknesses that could be exploited to steal data or disrupt operations.

Texas has responded by centralizing its cyber incident response capabilities. The Texas Cyber Command is a smart step forward. It brings coordination and focus to an increasingly complex landscape. But its effectiveness will depend entirely on the professionals tasked with doing the work. And that’s where the challenge lies.

The workforce gap

Across the U.S., there are an estimated 400,000 unfilled cybersecurity positions. In Texas, more than 40,000 roles remain vacant, according to CyberSeek. These are not just numbers in a report. They represent a growing vulnerability with gaps in frontline defenses against real and persistent threats.

We cannot afford to rely solely on traditional pathways to fill this gap. Four-year degree programs are important, but they are not designed to scale fast enough or flexibly enough to meet today’s needs. Instead, we need to broaden our view of what a cybersecurity talent pipeline looks like and who it includes.

There needs to be an expanded focus on practical, skills-based training that takes high-aptitude individuals, including those from non-traditional backgrounds, and prepares them for success in cybersecurity careers through rigorous hands-on training that reflects the demands of real-world cyber roles. With the right structure and support, people from all walks of life are already proving they can become capable defenders of our digital infrastructure.

The same entrepreneurial spirit that drives innovation in other sectors can be applied to cybersecurity workforce development. We don’t have to wait years to grow the next generation of defenders. We can do it now, with the right focus and investment.

Texas has taken a critical first step by creating the Cyber Command, but if we want to build lasting resilience, we need to address the workforce bottleneck head-on. Cybersecurity needs more than tech…it needs talent.
