    Houston company behind game changing artificial heart gets FDA green light

    Houston company with a breakthrough heart health tech has received a green light from the FDA.

    BiVACOR, a Houston-headquartered medical device company, has received FDA approval for its Total Artificial Heart (BTAH) IDE first-in-human early feasibility study (EFS). The BTAH device itself is designed to take over all function for patients with heart failure. The BTAH is roughly the size of a human fist, which means that, while it could support an active adult male, it may also fit many women and children.

    Led by CEO Thomas Vassiliades, a former heart surgeon, BiVACOR is based on a system of magnetic levitation. “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,” Vassiliades told InnovationMap in a podcast earlier this year.

    Because of that, BiVACOR could potentially last for a patient’s entire life with no wear — something, Vassiliades explains, is new to the field.

    The EFS includes 10 hospitals enrolled as possible sites and is slated to begin in 2024. One location is Houston’s own Texas Heart Institute.

    Houston lands on 2026 list of best big cities for starting a business

    Houston has finally made it into the top 30 best large U.S. cities for starting a business.

    Houston has reaffirmed its commitment to a business-friendly environment and now ranks as the 26th best large U.S. city for starting a business in 2026. The city jumped up eight places after ranking 34th last year.

    WalletHub's annual report compared 100 U.S. cities based on 19 relevant metrics across three key dimensions: business environment, access to resources, and costs. Factors that were analyzed include five-year business survival rates, job growth comparisons from 2020 and 2024, population growth of working-age individuals aged 16-64, office space affordability, and more.

    Florida cities locked out the top five best places in America for starting a new business: Tampa, Orlando, Jacksonville, Hialeah, and St. Petersburg.

    Houston's business environment ranked as the 19th best in the country, and the city ranked 51st in the "business costs" category. However, the city lagged behind in the "access to resources" ranking, coming in at No. 72 overall. This category examined metrics such as Houston's working-age population growth, the share of college-educated individuals, financing accessibility, the prevalence of investors, venture investment amounts per capita, and more.

    "From the Gold Rush and the Industrial Revolution to the Internet Age, periods of innovation have shaped our economy and driven major societal progress," the report's author wrote. "However, the past few years have been particularly challenging for business owners in the U.S., due to factors such as the COVID-19 pandemic, the Great Resignation and high inflation."

    Earlier this year, WalletHub declared Texas the third-best state for starting a business in 2026, and several Houston-area cities have seen robust growth after being recognized among the best career hotspots in the U.S. Entrepreneurial praise has also been extended to five local companies that were named the most innovative companies in the world, and six powerhouse female innovators that made Fortune's 2026 Female Founders 500 list.

    Texas cities with strong environments for new businesses
    Multiple cities in the Dallas-Fort Worth Metroplex can claim bragging rights as the best Texas locales for starting a new business. Dallas ranked highest overall — appearing 11th nationally — and Irving landed a few spots behind in the 16th spot. Arlington (No. 23), Fort Worth (No. 30), Plano, (No. 35), and Garland (No. 65) followed behind.

    Only six other Texas cities earned spots in the report: Austin (No. 24), Lubbock (No. 36), Corpus Christi (No. 39), San Antonio (No. 64), El Paso (No. 67), and Laredo (No. 76).

    Austin tied with Boise, Idaho and Fresno, California for the highest average growth in the number of small businesses nationally, while Corpus Christi and Laredo topped a separate list of the U.S. cities with the most accessible financing.
