Robotic neurosurgery is an exciting new frontier in medicine, and Houston-based medtech firm XCath is leading the charge with its revolutionary Iris robotic system. The company announced in March that it had secured $30 million in Series C funding to continue developing systems to tackle blood clots in the human brain.

“We are grateful to our investors for their conviction in our shared mission to improve clinical outcomes for patients impacted by endovascular diseases,” Eduardo Fonseca, CEO of XCath, said in a news release. “In 2025, the XCath team advanced the frontiers of endovascular robotics. This funding accelerates our commitment to expanding access to life-saving care so that where a patient lives no longer determines whether they live.”

XCath–which also has campuses in Pangyo, South Korea–has already achieved a number of remarkable firsts in robotic neurosurgery. The Iris is the only endovascular robotic system currently in development to perform intracranial navigation or neurointerventional treatment, and is the only robot in the world to have performed an intracranial neurovascular procedure involving the robotic manipulation of three devices.

These new Series C funds, which bring the company's total investment to $92 million, will go toward developing a clinical telerobot capable of performing a mechanical thrombectomy. This would bring unprecedented accuracy and precision to the surgical removal of brain clots, significantly reducing the risk of neurosurgery.

“Robotic surgery succeeds when innovation is paired with practical execution,” Dr. Fred Moll, chairman of the XCath board of directors, said in the release. “XCath has built a promising technology foundation, and just as importantly, a team that values rigor and appreciates perspective. I’m excited to support them as they take on the mission of globalizing access to gold-standard care for stroke patients.”

In November 2025, the Iris debuted under the control of Dr. Vitor Mendes Pereira at The Panama Clinic in Panama City, alongside local Principal Investigator Dr. Anastasio Ameijeiras Sibauste. It was only the second time in human history that a robot had been used for intracranial neurovascular intervention, and it established Iris as a viable technology in the fight against stroke.

“Treatment of stroke and other neurovascular diseases represents one of the most significant financial opportunities in healthcare, supported by positive reimbursement dynamics and strong demand from health systems,” Nicholas Drysdale, CFO of XCath, added in the release. “With our continued investor support and disciplined capital deployment, XCath is positioned to build a category-leading platform in endovascular robotics”.

Despite having success in taking his technology from lab to commercialization, Anwar Sadek made the strategic decision to move his company, Corrolytics, from where it was founded in Ohio to Houston.

"Houston is the energy capital of the world. For the technology we are developing, it is the most strategic move for us to be in this ecosystem and in this city where all the energy companies are, where all the investors in the energy space are — and things are moving really fast in Houston in terms of energy transition and developing the current infrastructure," Sadek, co-founder and CEO of Corrolytics, says on the Houston Innovators Podcast.

And as big as a move as it was, it was worth it, Sadek says.

"It's been only a year that we've been here, but we've made the most developments, the most outreach to clients in this one last year." Continue reading.

A Houston surgical robotics company has gotten a Investigational Device Exemption from the FDA to go forward with human trials.

This news allows EndoQuest Robotics to begin its Prospective Assessment of a Robotic-Assisted Device in Gastrointestinal Medicine (PARADIGM) study, which will be conducted at leading United States health care facilities, including Brigham and Women’s Hospital (Boston), Mayo Clinic (Scottsdale), Cleveland Clinic (Cleveland), AdventHealth (Orlando), and HCA Healthcare (Houston). The study will include surgeries on 50 subjects, who will hopefully begin to enroll in January.

“The foundational thesis is we're trying to make sure that the world's largest medical center is also the world's largest med tech innovation center,” Eduardo Fonseca, interim CEO of EndoQuest Robotics, tells InnovationMap. Continue reading.

FDA greenlights Houston surgery robotics company's unique technology

headed to clinical trials

A Houston surgical robotics company has gotten a Investigational Device Exemption from the FDA to go forward with human trials.

This news allows EndoQuest Robotics to begin its Prospective Assessment of a Robotic-Assisted Device in Gastrointestinal Medicine (PARADIGM) study, which will be conducted at leading United States health care facilities, including Brigham and Women’s Hospital (Boston), Mayo Clinic (Scottsdale), Cleveland Clinic (Cleveland), AdventHealth (Orlando), and HCA Healthcare (Houston). The study will include surgeries on 50 subjects, who will hopefully begin to enroll in January.

“The foundational thesis is we're trying to make sure that the world's largest medical center is also the world's largest med tech innovation center,” Eduardo Fonseca, interim CEO of EndoQuest Robotics, tells InnovationMap.

His company is well on its way to helping to assure that, through making history of its own. EndoQuest is behind the world's first Flexible Robotic Surgical System, a technology that may one day transform surgery as we know it.

The idea to use these novel robots for surgery came from Dr. Todd Wilson, a surgeon at UTHealth Houston, who spent his medical education, residency, and fellowship at the institution.

“I had really focused in my practice on trying to do everything possible to improve outcomes for patients,” Wilson explains. “And there seemed to be a pretty good correlation that the smaller the incisions or the fewer incisions, the better patients would do.”

The stumbling block? The necessary small incisions are difficult for human surgeons to make with current technology. But UTHealth was part of the solution.

“Right there in the University of Texas was a microsurgical lab where they were focusing on trying to develop robotics, but the application was still a little bit fuzzy,” Wilson says.

Using their innovations to solve Wilson’s problem turned out to be the start of the company now known as EndoQuest Robotics.

The first indication for the system is for colon lesions. But in the future it could be used for practically any minimally invasive surgery (MIS). That means that the robots could help to perform anything from a tonsillectomy to cholecystectomy (gallbladder removal) to non-invasive colorectal procedures, should those lesions prove to be cancerous.

According to Fonseca, last year was the first on record that there were more MIS, including laparoscopic and robotic surgeries, than conventional ones in the U.S. The time is right to forge ahead with the flexible robotic surgical system. Days ago, the EndoQuest team announced that its Investigational Device Exemption (IDE) application for its pivotal colorectal clinical study was approved by the FDA.

“Our end point is a device that can be mass-manufactured and very safe for patients and has a short learning curve, so therefore, we intend to learn a lot during these trials that will inform our ultimate design,” says Fonseca.

He adds that it’s a “brilliant” group of engineers that has set EndQuest apart, including both teams in Houston and in South Korea.

“We can move twice as fast as anyone else,” jokes engineer Jiwon Choi.

Despite the extra brain power provided by the South Korea engineers, Fonseca says that EndoQuest’s beginnings are “as much of a Houston story as you could find.”

Orion vehicle manager reflects on Artemis II, looks to 2028 moon mission

Q&A

Humanity is finally headed back to the moon after more than half a century. This year's launch of the Artemis II mission in the Orion spacecraft put four crew members in lunar orbit and tested the new ship developed by Lockheed Martin.

Everything went smoothly, safely returning astronauts home, but there is always room to improve. InnovationMap chatted via email with Orion vehicle manager Branelle Rodriguez, shortly after a talk at The Ion, for insight on how Orion might perform in the future as the next lunar landing approaches in early 2028.

InnovationMap: How satisfied are you with the way Orion operated on this past mission?

Branelle Rodriguez: Orion performed exceptionally well during Artemis II, successfully demonstrating critical spacecraft capabilities, including life support systems, displays and controls, and executing manual piloting operations. Artemis II brought humans back to the moon, achieving key exploration and scientific imagery, while validating systems essential for future Artemis missions.

IM: What is the most important thing you learned about improving Orion for the next mission?

BR: The Artemis II mission provided invaluable insights into crew operations and spacecraft performance in a deep-space environment. With every mission, NASA applies lessons learned to continuously improve Orion’s operations, validate design and ensure mission readiness. Artemis II offered our first opportunity to evaluate several new systems and gain a deeper understanding of what it is like for astronauts to live and work inside the spacecraft. The operational, technical and human factors data collected are being integrated across the program to refine future missions, reduce risk and enhance overall mission success.

IM: How has Orion helped the mission to explore space?

BR: Orion is one of NASA’s foundational elements for human deep space exploration—not only supporting the mission but serving as a core component of it. It is currently the only spacecraft capable of carrying crew on deep space missions and returning them safely to Earth from the high speeds required from the vicinity of the moon. No other spacecraft has the technology to endure the extremes that come with human deep-space travel, such as advanced environmental and life support, navigation, communications, radiation shielding, and the world’s largest ablative heat shield to protect the astronauts during reentry into Earth’s atmosphere. Orion has already taken astronauts to explore space farther than ever before—252,756 miles from Earth— and will carry crews to the moon on future missions to explore the lunar South Pole region. The astronauts’ observations, samples, and data collected on these future missions will expand our understanding of our solar system and home planet.

Houston VC funding nears $1B in first half of 2026, report says

by the numbers

Despite a weak second quarter, venture capital funding for Houston-area startups approached $1 billion in the first half of 2026, the region’s highest first-half total since 2022, according to the latest PitchBook-NVCA Venture Monitor.

This year’s first-half total of $962.4 million represented a nearly 8 percent increase over last year’s first-half total of $891.7 million. Dating back to 2016, this year’s first-half haul lags behind only 2021 and 2022 for the most first-half funding.

Houston’s year-over-year VC jump of 73 percent in the first quarter of 2026 more than made up for the year-over-year drop of 34 percent in the second quarter of 2026, according to the report.

Deal count tells a more encouraging story: Houston startups closed 102 deals in the first half, up from 93 a year earlier and the region’s busiest first half since 2022. However, the average deal size shrank, as no single funding source dominated the total.

Keep in mind that PitchBook and NVCA routinely revise quarterly numbers upward to reflect deals that were reported after a previous quarter’s data was published. So, in the case of Houston, numbers initially reported for the first quarter of 2026 may not match newly reported numbers.

Perhaps the most notable Houston-area deal announced in the first half of this year was Cart.com’s $180 million growth equity investment, led by Springcoast Partners. Cart.com is an e-commerce platform and logistics provider.

PitchBook-NVCA data shows Houston’s VC activity is growing modestly, delivering better numbers in the first half of 2026 versus 2024 and 2025, but it still sits below the highs of 2021 and 2022. This is one sign that so far in 2026, the national VC boom isn’t benefiting non-hub markets like Houston the way it’s boosting some hub markets, especially Silicon Valley and New York City.

Nationwide, AI dominated VC funding in the first half of this year. The sector made up 86 percent of VC from January through June. The report notes that the markets have still struggled to unlock IPOs, with SpaceX being the biggest exception, and few M&A deals outside health care have been significant.
