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.

mover and shaker

A Houston-based preclinical artificial heart device company has a new head honcho as it grows its team and further develops its technology.

BiVACOR named Thomas Vassiliades as CEO effective immediately. He replaces the company's founder, Daniel Timms, in the position. BiVACOR is on track to head toward human clinical trials and commercialization, and Vassiliades is tasked with leading the way.

“BiVACOR led an extensive CEO search, and Tom was the clear choice given his experience, background, leadership style, and exceptional track record,” says Timms in a news release. “Tom has the skillset and credibility to guide BiVACOR through its next chapter of transformation and advancement as we undertake the next stage of clinical activities leading up to First in Human early feasibility studies.”

Vassiliades has over 30 years of experience within the medical device industry as well as cardiothoracic surgery. He was most recently the general manager of the surgery and heart failure business at Abiomed and held several leadership roles at Medtronic. Dr. Vassiliades received his MD from the University of North Carolina, and his MBA was achieved with distinction at Emory University.

“I am excited and honored to join the BiVACOR team, working closely with Daniel and the entire team as we look forward to bringing this life-changing technology to the market,” says Dr. Vassiliades in the release. “Throughout my career, I’ve been guided by the goal of bringing innovative cardiovascular therapies to the market to improve patient care and outcomes – providing solutions for those that don’t have one. BiVACOR is uniquely well-positioned to provide long-term therapy for patients with severe biventricular heart failure.”

Timms will take over BiVACOR's technical team working on the Total Artificial Heart system as CTO. The device, billed as the first long-term therapy for patients with severe heart failure, is an implantable artificial heart based on rotary blood-pump technology. Similar in size to an adult fist, it is small enough to be implanted in many women and some children yet capable of delivering enough cardiac power to a man who's exercising. Unlike the two-chamber human heart, BiVACOR's device features a single chamber.

The medical device company, which has operations in Houston and Australia, recently announced the addition of eight new employees doubling their team. The growth comes following its series B raise last year.

“It is a testament to the great progress the team has made and to the importance of the unmet clinical need addressed by the Total artificial Heart technology," Timms says on the appointment of Vassiliades. "We look forward to Tom’s leadership as BiVACOR navigates the path to commercialization.”

Houston named a top market for remote tech workers, startup doubles its staff, and more innovation news

short stories

Houston is starting 2022 strong in terms of innovation news, and there might be some headlines you may have missed.

In this roundup of short stories within Houston startups and tech, the Bayou City is ranked based on its ability to employ remote tech talent, a coworking company opens a new location, a med device startup doubles its staff, and more.

New report finds Houston a top market for remote tech talent

In a new report, Karat — a Seattle-based human resources company — looked at which metros were best for attracting remote tech talent. The company first completed the report based on 2020 due to a changing workforce spurred by the pandemic.

"Last year we took our first look at the rapidly expanding remote software engineer hiring landscape. As more organizations shifted to remote or hybrid working models we had started to see significantly improving candidate performance outside of the more-established tech hubs," writes Patrick Wu, data analyst at Karat, in a blog post. "Today, as even more top tech companies commit to hiring remote software engineers, we’re taking a look at how this landscape has continued to evolve."

Houston ranked No. 6 this year in the list of 10 metros just ahead of No. 7 Austin. Last year, Houston ranked as No. 2 and Dallas at No. 9, but that North Texas metro fell off the top 10 for 2021. Pittsburgh maintained its top spot on this list year over year.

Houston-based artificial heart company snags $22M in fresh funds

money moves

Houston-based medtech company BiVACOR has picked up $22 million in funding — in the form of a series B round and a federal grant — to propel development of its Total Artificial Heart device for treatment of severe heart failure.

In a May 19 news release, BiVACOR says it received a series B round of $19 million and a National Institutes of Health grant of $3 million. Boston-based Cormorant Asset Management and Australia's OneVentures, through its OneVentures Healthcare Fund III, led the round.

OneVentures first invested in BiVACOR three years ago. According to Australia's Financial Review, OneVentures initially pumped $3 million (Australian dollars) into BiVACOR, with the potential of contributing as much as $10 million if BiVACOR met certain milestones. BiVACOR received a round of seed funding from U.S. investors in 2013.

"BiVACOR's one-of-a-kind technology is supported by a remarkable team that has moved this technology a significant distance toward the clinic," Paul Kelly, managing partner of OneVentures, says in BiVACOR's news release.

The fresh cash will support preparation for the first human trials of the device. As a short-term measure, the device can be implanted in someone awaiting a heart transplant. It's also designed to be a long-term alternative to a heart transplant.

The BiVACOR device, billed as the first long-term therapy for patients with severe heart failure, is an implantable artificial heart based on rotary blood-pump technology. Similar in size to an adult fist, it is small enough to be implanted in many women and some children yet capable of delivering enough cardiac power to a man who's exercising. Unlike the two-chamber human heart, BiVACOR's device features a single chamber.

"The commitment and interest from our investors validate our technology and the need for improved options to treat end-stage biventricular heart failure," says Daniel Timms, founder and CEO of BiVACOR. "With this financing, we will be able to expand our world-class team and undertake … verification activities so that we can commence our first-in-human early feasibility study in the near future."

Founded in 2008, BiVACOR maintains offices in Cerritos, California, and Brisbane, Australia. The company is affiliated with Houston's Texas Heart Institute, where the world's first artificial heart was implanted. BiVACOR's headquarters is at the Texas Medical Center complex.

The company employs about a dozen people and says the funding will enable it to bring on another 10 employees.

For 13 years, BiVACOR has been working on technology aimed at eliminating the need for heart transplants. Thus far, the BiVACOR device has been tested only on cows.

"In heart failure, the heart becomes unable to pump enough blood to keep the body healthy and strong. At least 26 million people around the world are living with the disease, and the number is rising as populations age," IEEE Spectrum reported in 2019. "Patients with severe heart failure have a bleak outlook: Their best option is a heart transplant, but the limited number of donor hearts means that only about 5,000 patients around the world receive transplants each year. Thousands more patients are eligible for transplants, and some die while waiting for a donor organ."

Italian aerospace company sets up first U.S. office at Houston Spaceport

welcome to houston

Como, Italy-based aerospace company Involve Space recently made the Houston Spaceport the site of its first U.S. office.

Involve Space develops high-altitude balloon platforms for Earth observation, scientific research and hardware testing. The balloons carry instruments into the stratosphere (a layer of the upper atmosphere) to collect images and data, conduct experiments and test technology.

The company plans to launch its first commercial missions from Houston by the end of this year, according to a news release.

“Houston is the global center of aerospace, and our presence at Houston Spaceport strengthens our international growth trajectory,” Jonathan Polotto, founder and CEO of Involve Space, said in the release.

Founded in 2021, Involve Space incorporates aerospace hardware, AI and geospatial tools into its offerings. Its proprietary CLEAR platform uses conversational AI to help customers interpret data and support decision-making.

Located at Ellington Airport, the Houston Spaceport provides a base for Involve Space’s North American operations, including business development and partnerships with aerospace companies and researchers.

Other tenants at the Houston Spaceport include NASA, Axiom Space, Venus Aerospace and Intuitive Machines.

Involve Space’s relationship with the Houston Spaceport began in January 2025, when it conducted its first U.S. pilot launch. During the five-hour mission, the balloon reached an altitude of about 85,000 feet and traveled about 250 miles across Texas.

One of Involve Space’s first U.S. customers is Houston-based Rhodium Scientific, a space biotech company. Polotto and Rhodium Scientific founder and CEO Olivia Gamez Holzhaus signed a deal to conduct biotech experiments aboard Involve Space’s stratospheric balloon platforms before planned missions to orbit.

“The presence of innovative platforms like those developed by Involve strengthens the Spaceport’s role as a site for testing, validating, and deploying advanced technologies between aeronautics and space,” Jim Szczesniak, director of aviation for Houston Airports, added in the release.
