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.

BiVACOR, a Houston-based cardiatric medical device company, announced that it has doubled the size of its team with the addition of eight team members. The growth comes following its series B raise last year.

“The diversity of skills and experience throughout the company is something we are very proud of, and I am pleased to welcome this all-star group of individuals to the team,” says Daniel Timms, BiVACOR founder and CEO, in a December news release. “They will each play an integral role in the overall accomplishments of BiVACOR, specifically as we undertake benchtop and preclinical verification activities so that we can commence our First in Human early feasibility study in the near future.”

Here's who recently joined the company at both its United States and Australia-based operations:

  • Nathan Kong, purchasing administrator
  • Farhad Akhavan, systems engineer
  • David Duarte, verification and validation engineer
  • Paul Chiver, manufacturing technician
  • Lindsey Brede, financial controller
  • Dawnel Scott, director QA/RA
  • Mairi Maclean, director of product development
  • Nicole Bartnikowski, scientific manager (Australia)

“Having the ability to attract and hire individuals with the industry knowledge and pedigrees of this world-class team is a testament to how BiVACOR is perceived in the industry," Timms continues. "Each of them brings a unique perspective and skillset to BiVACOR and will play an important role in furthering our technology.”

BiVACOR is developing its Total Artificial Heart, or TAH. 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.

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."

NASA revamps Artemis moon landing program by modeling it after Apollo

To the moon

NASA is revamping its Artemis moon exploration program to make it more like the fast-paced Apollo program half a century ago, adding an extra practice flight before attempting a high-risk lunar landing with a crew in two years.

The overhaul in the flight lineup came just days after NASA’s new moon rocket returned to its hangar for more repairs, and a safety panel warned the space agency to scale back its overly ambitious goals for humanity’s first lunar landing since 1972.

Artemis II, a lunar fly-around by four astronauts, is off until at least April because of rocket problems.

The follow-up mission, Artemis III, had been targeting a landing near the moon’s south pole by another pair of astronauts in about three years. But with long gaps between flights and concern growing over the readiness of a lunar lander and moonwalking suits, NASA’s new administrator Jared Isaacman announced that mission would instead focus on launching a lunar lander into orbit around Earth in 2027 for docking practice by astronauts flying in an Orion capsule.

The new plan calls for a moon landing — potentially even two moon landings — by astronauts in 2028.

“Everybody agrees. This is the only way forward,” Isaacman said.

The hydrogen fuel leaks and helium flow problems that struck the Space Launch System rocket on the pad at NASA's Kennedy Space Center in February also plagued the first Artemis test flight without a crew in 2022.

Another three-year gap was looming between Artemis II and the moon landing by astronauts as originally envisioned, Isaacman said.

Isaacman stressed that “it should be incredibly obvious” that three years between flights is unacceptable. He'd like to get it down to one year or even less.

Isaacman, a tech billionaire who bought his own trips to orbit and performed the world’s first private spacewalk, took the helm at NASA in December.

During NASA’s storied Apollo program, he said, astronauts’ first flight to the moon was followed by two more missions before Neil Armstrong and Buzz Aldrin landed on the moon. What's more, he added, the Apollo moonshots followed one another in quick succession, just as the earlier Projects Mercury and Gemini had rapid flight rates, sometimes coming just a few months apart.

Twenty-four Apollo astronauts flew to the moon from 1968 through 1972, with 12 of them landing.

“No one at NASA forgot their history books. They knew how to do this," Isaacman said. “Now we're putting it in action.”

To pick up the pace and reduce risk, NASA will standardize its Space Launch System rockets moving forward, Isaacman said. These are the massive rockets that will launch astronauts to the moon aboard Orion capsules. At the same time, Elon Musk's SpaceX and Jeff Bezos' Blue Origin are speeding up their work on the landers needed to get the astronauts from lunar orbit down to the surface.

Isaacman said next year will see an Orion crew rendezvousing in orbit around Earth with SpaceX's Starship, Blue Origin's Blue Moon or both landers. It's similar to the methodical approach that worked so well during Apollo in the late 1960s, he noted. Apollo 8, astronauts' first flight to the moon, was followed by two more missions before Armstrong and Aldrin aimed for the lunar surface.

“We should be getting back to basics and doing what we know works,” he said.

The Aerospace Safety Advisory Panel recommended that NASA revise its objectives for Artemis III “given the demanding mission goals.” It’s urgent the space agency do that, the panel said, if the United States hopes to safely return astronauts to the moon. Isaacman said the revised Artemis flight plan addresses the panel's concerns and is supported by industry and the Trump administration.

Booming Houston suburb launches innovation grant to attract startups

innovation incentive

Think you’ve got a burgeoning startup? Consider moving it to southwest Houston. The City of Sugar Land announced the Sugar Land Starts Innovation Fund last week to support companies that move jobs to the area.

“The Sugar Land Starts Innovation Fund is designed to support companies that are ready to grow and make a meaningful, long-term commitment to our community,” Colby Millenbruch, business recruitment manager for the City of Sugar Land, said in a news release. “By focusing on revenue-generating startups and performance-based incentives, we are creating a clear pathway for innovative companies to scale while reenergizing existing office space.”

The performance-based, non-equity dilutive grant program is open to companies that demonstrate at least $250,000 in generated revenue or $500,000 in institutional backing from a bank or venture capital firm. They must commit to hiring or relocating at least three employees in Sugar Land for a minimum of three years and at an average salary of $61,240. Compliance will be verified through Texas Workforce Commission reporting.

The fund builds off the Sugar Land Plug and Play partnership to turn the city into an innovative technology hub.

Collaboration with the Silicon Valley-based startup incubator and accelerator on a physical location in southwest Houston has supported 22 startups and has raised $6.5 million in capital since it officially launched in Sugar Land last March. Companies located at the Sugar Land Plug and Play include Synaps, a browser-based design platform for architects, and Intero Biosystems, which produces miniature human organs for preclinical drug development.

In addition to direct funding and business space, both the new grant and the overall Plug and Play project facilitate meetings with Houston-area businesses like CenterPoint Energy.

This should not only bring new industries to Sugar Land, but also allow existing companies to expand outward as technological investors to create a web of new progress.

“This investment is about more than technology. It’s about creating an environment where innovation can take root, grow, and deliver lasting value for the Sugar Land community,” David Steele, director of Texas at Plug and Play, added in the release. “Sugar Land is setting itself apart by taking a long-term view, investing in founders, partnerships, and technologies that will define the next chapter of growth. We’re proud to partner with the city in building an innovation ecosystem that benefits both entrepreneurs and the broader community.”
