Houston medtech startup clears FDA approval for new surgical tool

precision surgery

Houston-based Prana Surgical will soon bring a new electrosurgical tool to operating rooms around the country. The Prana System officially cleared U.S. Food and Drug Administration (FDA) approval earlier this month.

"Receiving FDA clearance for the Prana System represents a defining milestone for our company," Joanna Nathan, CEO and co-founder of Prana Surgical, said in a news release. "Surgeons today are increasingly focused on achieving precise outcomes while minimizing disruption to healthy tissue. The Prana System was designed to support that shift by integrating targeting and excision into a single, streamlined tool."

Prana Surgical began as Prana Thoracic in 2022. Back then, the company primarily focused on developing screening tools for lung cancer diagnosis. It raised $6 million in series A funding rounds in 2023 and 2024 before transitioning to broader surgical needs in 2025.

The Prana System is a minimally invasive, image-guided, single-use tissue extraction tool designed to retrieve samples without damaging healthy tissue. The tool is still designed with the respiratory system in mind, helping Prana in the fight against lung cancer and other thoracic diseases.

Reducing the impact of tissue extraction via electrosurgery and enhanced image scanning can significantly reduce complications. The Prana System combines localization and tissue-cutting capabilities in one, which keeps surgeons from having to swap out components during a procedure, making for a smoother process. It can core, cut and feel blood vessels on the way toward the intended target, giving surgeons greater control over tissue preservation.

"Electrosurgery is foundational to modern surgery, but there is still opportunity to improve how energy-based tools are applied in minimally invasive settings," Nathan added. "Our goal is to introduce a new class of image-guided surgical tools that enable more precise intervention across a range of procedures."

The company projects the market size for lung nodules to be $7.5 billion in the United States, estimating that 2.5 million nodules will be able to benefit from the new tool. While starting out focused on biopsies, the company plans to evolve the system into other procedures, such as ablation, in the future. It is also planning for a controlled U.S. clinical rollout as it moves toward commercialization

fresh funding

A Houston-based medtech startup with an innovative tool that's aiming to transform lung cancer intervention has closed its series A extension round.

Prana Thoracic announced an additional $3 million in funding, a raise that was oversubscribed by 30 percent, reports the company. The company's series A originally closed in March 2023 at $3 million. In August of 2022, the company secured $3 million in grant funding.

"We are grateful for the overwhelming support from our investors in this financing round. Their confidence in our mission and plan is motivating,” Joanna Nathan, CEO and co-founder of Prana Thoracic, says in a news release. “This additional funding will enable us to accelerate our efforts in bringing precision surgical solutions to lung cancer patients worldwide.”

The extension included participation from new investors, including cultivate(MD), GenHenn Capital, and Houston Angel Network, as well as from prior lead investor New World Angels. Existing investors — Johnson & Johnson Development Corp, Texas Medical Center Venture Fund, and the Cancer Prevention & Research Institute of Texas (CPRIT) — also support the company.

"We are excited to support Prana Thoracic in their mission to improve lung cancer treatment. Their innovative approach has the potential to significantly impact patient outcomes," says Dr. R. Sean Churchill, managing director of cultivate(MD), in the release.

The additional funding will support the company as it advances through its clinical and regulatory plans.

“The team has made remarkable progress in developing this novel and minimally invasive technique for lung tissue excision, which has the potential to transform the diagnosis and treatment of early-stage lung cancer," adds Dr. Edward M. Boyle, founder and director at the company. "Beyond lung applications, they are pioneering new methods to use this technology for other soft tissues and are actively exploring integration with ablation and robotic systems, aligning with the future direction of these fields."

In 2022, Nathan joined the Houston Innovators Podcast to discuss her passion for Prana Thoracic's innovation. Listen to the episode below.

4 Houston startups selected for preeminent medtech accelerator

ready to grow

Four Houston startups have been selected for the 2023 cohort of the MedTech Innovator’s four-month accelerator program.

Los Angeles-based MedTech Innovator, which bills itself as the world’s largest medtech accelerator, will award $800,000 in funding to winners of its competitions throughout the 2023 program. The grand prize is $350,000.

Almost 1,200 startups applied to participate in this year’s accelerator. From that group, MedTech Innovator, its corporate partners, and more than 400 judges picked nearly 200 candidates for in-person pitching and partnering events. Sixty-one startups ultimately were chosen for the 2023 cohort, which kicks off June 14 and 15.

Forty-two of the 61 startups will participate in MedTech Innovator’s corporate mentorship program, and five companies will join a plastic surgery accelerator in conjunction with the American Society for Plastic Surgeons.

MedTech Innovator says more than 500 startups have completed its accelerator program and have secured $6.8 billion in follow-on funding.

“We are proud of our stellar track record of identifying and perfecting the most innovative medtech startups in the world,” Paul Grand, CEO and founder of MedTech Innovator, says in a news release.

The four Houston companies selected for the MedTech Accelerator’s 2023 cohort are:

  • Ankr. The startup (whose name is pronounced “anchor”) provides a caregiving platform for cancer patients in the U.S. As of 2022, there were an estimated 18.1 million cancer survivors across the country. The company won The Ion’s Houston Startup Showcase in 2021.
  • NeuraStasis. The startup is developing an electrical stimulation device to delay the effects of acute ischemic stroke. This type of stroke happens when blood flow to the brain decreases. Acute ischemic stroke affects about 700,000 people in the U.S. each year. The company was selected for last year’s cohort of the UCSF Rosenman Institute’s Rosenman Innovators program.
  • Nininger Medical. The startup is working on a device for minimally invasive replacement of the tricuspid valve. Today, an estimated 1.6 million Americans experience tricuspid regurgitation. This type of heart disease occurs when the tricuspid valve’s flaps don’t close correctly. In 2021, the company received a $256,000 National Science Foundation grant.
  • Prana Thoracic. The startup is developing a tool for minimally invasive removal of lung tissue in lung cancer patients. In March, the company announced $3 million in series A funding.

Last year, three Houston companies were selected for the program. The startups — Ad Vital, Corveus Medical, and CorInnova.

money moves

It's been just under six months since the launch of Prana Thoracic, a Houston health tech startup tackling lung cancer diagnostics, and the company has already secured its next round of investment funding.

Prana Thoracic, a medical device company developing a tool for early interception of lung cancer, announced last week that it closed a $3 million series A financing round led by Florida-based New World Angels with participation from Johnson & Johnson Innovation – JJDC, Inc., Texas Medical Center Venture Fund, and the University City Science Center’s Phase 1 Ventures.

In August, the company received a $3 million award from the Cancer Prevention & Research Institute of Texas. All of Prana Thoracic's funding is being used to develop the unique diagnostic product and the company's path to first-in-human clinical studies.

“Our technology provides a definitive answer to patients with lung nodules and allows physicians to intervene earlier in the lung cancer patient’s journey,” says Joanna Nathan, CEO, and co-founder of Prana, in a news release. “Our team is grateful to have the support of our investors and excited to leverage this financing to accelerate our technology to the bedside.”

The company's technology is a minimally invasive, tissue-sparing nodulectomy tool that can evaluate suspicious pulmonary nodules early on in hopes of being able to catch and treat patients with lung cancer. The tool's development originated on the grounds of the Texas Medical Center in collaboration with Precision Thoracic Corp.

“Prana’s cutting-edge technology was developed on the TMC campus, and we are excited to continue to support Prana in meeting its next milestone through funding from the TMC Venture Fund. The technology they are spearheading could be a game changer in how physicians detect and treat lung cancer. Congratulations to the team on this exciting announcement,” says William McKeon, president and CEO of the Texas Medical Center, in the release.

Micheal Haimour, director of New World Angels, has joined Prana as a board member.

“We are delighted to support CEO Joanna Nathan and her team at Prana as they seek to develop solutions for the early detection and intervention of lung cancer,” he says in the release

Since the company emerged from stealth last summer, Prana has added a few feathers to its cap as a startup. In November, Nathan pitched and won first place at Ignite Healthcare Network’s annual Fire Pitch Competition. Prana was also named a finalist in the Female-Founded Businesses category of the Houston Innovation Awards. Currently, Prana is a member of the Spring 2023 cohort of the TMCi HealthTech Accelerator.

Houston quantum energy chip startup emerges from stealth with $12M round

seed funding

Houston-based Casimir has emerged from stealth with a $12 million seed round to commercialize its quantum energy chip.

The round was led by Austin-based Scout Ventures. Lavrock Ventures, Cottonwood Technology, Capital Factory, American Deep Tech, and Tim Draper of Draper Associates also participated in the round. The oversubscribed round exceeded the company’s original $8 million target, according to a news release.

Casimir’s semiconductor chips can generate power from quantum vacuum fields without the need for batteries or charging. The company plans to commercialize its first-generation MicroSparc chip by 2028.

The MicroSparc chip measures 5 millimeters by 5 millimeters and is designed to produce 1.5 volts at 25 microamps, comparable to a small rechargeable battery, without degradation and no replacement cycle.

“Casimir represents exactly the kind of breakthrough dual-use technology Scout Ventures was built to back,” Brad Harrison, founder and managing partner at Scout Ventures, said in the release. “This is based on 100 years of science and we’re finally approaching a commercial product … We’re proud to lead this round and support Casimir’s journey from applied science to deployed technology.”

Casimir says it aims to scale its technology across the ”full power spectrum,” including large-scale energy systems that can power homes, commercial infrastructures and electric vehicles.

Casimir's scientific work has been supported by DARPA-funded nanofabrication research and its technology was incubated at the Limitless Space Institute (LSI). LSI is a nonprofit that works to innovate interstellar travel and was founded by Kam Ghaffarian. Technology investor and serial entrepreneur Ghaffarian has been behind companies like X-energy, Intuitive Machines, Axiom Space and Quantum Space.

Harold “Sonny” White, founder and CEO of Casimir, believes the technology can power devices for years without replacements.

“Millions of devices will operate for years without a battery ever needing to be replaced or recharged because we have engineered a customized Casimir cavity into hardware capable of producing persistent electrical power,” White added in the release. “I spent nearly two decades at NASA studying how we power humanity’s future. That work led me to the Casimir effect and the quantum vacuum, where new tools have allowed us to build on a century of scientific knowledge and bring abundant power to the world.”

Houston-based Fervo Energy bumps up IPO target to $1.82 billion

IPO update

Houston-based geothermal power company Fervo Energy is now eyeing an IPO that would raise $1.75 billion to $1.82 billion, up from the previous target of $1.33 billion.

In paperwork filed Monday, May 11 with the U.S. Securities and Exchange Commission, Fervo says it plans to sell 70 million shares of Class A common stock at $25 to $26 per share.

In addition, Fervo expects to grant underwriters 30-day options to buy up to 8.33 million additional shares of Class A common stock. This could raise nearly $200 million.

When it announced the IPO on May 4, Fervo aimed to sell 55.56 million shares at $21 to $24 per share, which would have raised $1.17 billion to $1.33 billion. The initial valuation target was $6.5 billion.

A date for the IPO hasn’t been scheduled. Fervo’s stock will be listed on Nasdaq under the ticker symbol FRVO.

Fervo, founded in 2017, has attracted about $1.5 billion in funding from investors such as Bill Gates-founded Breakthrough Energy Ventures, Google, Mitsubishi Heavy Industries, Devon Energy (which is moving its headquarters to Houston), Tesla co-founder JB Straubel, CalSTRS, Liberty Mutual Investments, AllianceBernstein, JPMorgan, Bank of America and Sumitomo Mitsui Trust Bank.

Fervo’s marquee project is Cape Station in Beaver County, Utah, the world’s largest EGS (enhanced geothermal system) project. The first phase will deliver 100 megawatts of baseload clean power, with the second phase adding another 400 megawatts. The site can accommodate 2 gigawatts of geothermal energy. Fervo holds more than 595,000 leased acres for potential expansion.

Cape Station has secured power purchase agreements for the entire 500-megawatt capacity. Customers include Houston-based Shell Energy North America and Southern California Edison.
