Dr. Kenneth Liao is the only cardiatric surgeon in Houston — and one of only around 50 in the world — who uses a specific robot to conduct heart surgeries. The robot, known as the da Vinci, was first designed to assist in battlefield procedures.

Now on its fourth generation, the robot allows surgeons like Liao to treat heart diseases and conditions that typically would require open heart surgery through a one-to-two inch incision near the ribs. In many surgeries, it also allows surgeons to keep a patient's heart beating, lowering the risk of stroke.

"It's a totally game changing component to conventional surgery," Liao says. Read more.

Houston cardiac surgeon outpaces much of the country in game-changing robotics

matters of the heart

Dr. Kenneth Liao is pioneering a less invasive form of heart surgery at a time when distanced medicine has become more important than ever with the help of six team members and one robot.

As the chief of cardiothoracic transplantation and mechanical circulatory support at Baylor St. Luke's Medical Center, Liao has performed 116 robotic cardiac surgeries since coming on board in 2019 (as of press time). With Liao at the helm, Baylor St. Luke's has become a top cardiac robotics program in the country and is the only hospital in Houston to practice this highly-specialized form of surgery.

Liao's four-armed robot friend is known as the da Vinci robotic system and was first designed to assist in battlefield procedures. Now on its fourth generation, the robot allows surgeons like Liao to treat heart diseases and conditions that typically would require open heart surgery through a one-to-two inch incision near the ribs. In many surgeries, it also allows surgeons to keep a patient's heart beating, lowering the risk of stroke.

"It's a totally game changing component to conventional surgery," Liao says, who's one of about 50 surgeons in the country with his level of command over the tool.

Once inside, the da Vinci robot uses tiny instruments to perform surgical practices from suturing to cutting to tying a knot all within the rigid chest cage, which in a typical open heart surgery would have to be broken to perform such tasks.

The surgeon, who's seated about 10 feet away from the patient, controls the tools through a joystick connected to a computer console that shows an enhanced 3D view of the patient's chest. Liao says the screen provides a better visual of the heart than if he was seeing it with his own eyes, as it magnifies the field of surgery tenfold. This method also gives surgeons a better view of areas of the heart that they cannot easily see from above during traditional procedures.

The da Vinci can be used for bypass, grafting, pacemaker, and valve repair surgeries, and it has been proven to result in less blood loss and a faster, less painful recovery. Similar technology has also been adopted for prostate and gynecological surgeries. "It gives you the advantage of minimizing the trauma," Liao says.

And though the da Vinci was developed years before the pandemic, it puts patients at a lower risk of exposure to any outside contaminants, Liao adds, as the robot alone is interfacing with the patient through a small port, compared to doctors, nurses, and assistants hovering over an open chest cavity.

"Technology will theoretically reduce a patient's exposure to COVID in the operation room," he says. "I think that's common sense."

Liao was an early adopter of robotics, when the technology was much less user friendly. He performed the first robotic heart surgery in the state of Minnesota in 2003 and has worked with the developers of the da Vinci ever since to help improve the product after many other surgeons dismissed it.

He says today there is a renewed interest in the highly technical process and he believes it will become an emphasis for younger surgeons.

"This generation of surgeons are young and they are very indebted to computer technology and games. For them looking at screens and controlling the hand joystick control is much more familiar than for the older generation that was trained 20 years ago." he says.

The incredible technology helps, too. "A lot of times, as surgeons, we train in the old way. It's very difficult to change the systems," he says. "You need a major technology revolution to change the teaching and training."

2 Houston space tech cos. celebrate major tech milestones

big wins

Two Houston aerospace companies — Intuitive Machines and Venus Aerospace — have reached testing milestones for equipment they’re developing.

Intuitive Machines recently completed the first round of “human in the loop” testing for its Moon RACER (Reusable Autonomous Crewed Exploration Rover) lunar terrain vehicle. The company conducted the test at NASA’s Johnson Space Center.

RACER is one of three lunar terrain vehicles being considered by NASA for the space agency’s Artemis initiative, which will send astronauts to the moon.

NASA says human-in-the-loop testing can reveal design flaws and technical problems, and can lead to cost-efficient improvements. In addition, it can elevate the design process from 2D to 3D modeling.

Intuitive Machines says the testing “proved invaluable.” NASA astronauts served as test subjects who provided feedback about the Moon RACER’s functionality.

The Moon RACER, featuring a rechargeable electric battery and a robotic arm, will be able to accommodate two astronauts and more than 880 pounds of cargo. It’s being designed to pull a trailer loaded with more than 1,760 pounds of cargo.

Another Houston company, Venus Aerospace, recently achieved ignition of its VDR2 rocket engine. The engine, being developed in tandem with Ohio-based Velontra — which aims to produce hypersonic planes — combines the functions of a rotating detonation rocket engine with those of a ramjet.

A rotating detonation rocket engine, which isn’t equipped with moving parts, rapidly burns fuel via a supersonic detonation wave, according to the Air Force Research Laboratory. In turn, the engine delivers high performance in a small volume, the lab says. This savings in volume can offer range, speed, and affordability benefits compared with ramjets, rockets, and gas turbines.

A ramjet is a type of “air breathing” jet engine that does not include a rotary engine, according to the SKYbrary electronic database. Instead, it uses the forward motion of the engine to compress incoming air.

A ramjet can’t function at zero airspeed, so it can’t power an aircraft during all phases of flight, according to SKYbrary. Therefore, it must be paired with another kind of propulsion, such as a rotating detonation rocket engine, to enable acceleration at a speed where the ramjet can produce thrust.

“With this successful test and ignition, Venus Aerospace has demonstrated the exceptional ability to start a [ramjet] at takeoff speed, which is revolutionary,” the company says.

Venus Aerospace plans further testing of its engine in 2025.

METRO rolls out electric shuttles for downtown Houston commuters

on a roll

The innovative METRO microtransit program will be expanding to the downtown area, the Metropolitan Transit Authority of Harris County announced on Monday.

“Microtransit is a proven solution to get more people where they need to go safely and efficiently,” Houston Mayor John Whitmire said in a statement. “Connected communities are safer communities, and bringing microtransit to Houston builds on my promise for smart, fiscally-sound infrastructure growth.”

The program started in June 2023 when the city’s nonprofit Evolve Houston partnered with the for-profit Ryde company to offer free shuttle service to residents of Second and Third Ward. The shuttles are all-electric and take riders to bus stops, medical buildings, and grocery stores. Essentially, it works as a traditional ride-share service but focuses on multiple passengers in areas where bus access may involve hazards or other obstacles. Riders access the system through the Ride Circuit app.

So far, the microtransit system has made a positive impact in the wards according to METRO. This has led to the current expansion into the downtown area. The system is not designed to replace the standard bus service, but to help riders navigate to it through areas where bus service is more difficult.

“Integrating microtransit into METRO’s public transit system demonstrates a commitment to finding innovative solutions that meet our customers where they are,” said METRO Board Chair Elizabeth Gonzalez Brock. “This on-demand service provides a flexible, easier way to reach METRO buses and rail lines and will grow ridership by solving the first- and last-mile challenges that have hindered people’s ability to choose METRO.”

The City of Houston approved a renewal of the microtransit program in July, authorizing Evolve Houston to spend $1.3 million on it. Some, like council member Letitia Plummer, have questioned whether microtransit is really the future for METRO as the service cuts lines such as the University Corridor.

However, the microtransit system serves clear and longstanding needs in Houston. Getting to and from bus stops in the city with its long blocks, spread-out communities, and fickle pedestrian ways can be difficult, especially for poor or disabled riders. While the bus and rail work fine for longer distances, shorter ones can be underserved.

Even in places like downtown where stops are plentiful, movement between them can still involve walks of a mile or more, and may not serve for short trips.

“Our microtransit service is a game-changer for connecting people, and we are thrilled to launch it in downtown Houston,” said Evolve executive director Casey Brown. “The all-electric, on-demand service complements METRO’s existing fixed-route systems while offering a new solution for short trips. This launch marks an important milestone for our service, and we look forward to introducing additional zones in the new year — improving access to public transit and local destinations.”
