Medical device startup XCath announced on November 12 that it successfully treated three patients with brain aneurysms using its endovascular robotic system at The Panama Clinic in Panama City. The procedures represent a notable advance in neurovascular surgery—a field where precision measured in fractions of a millimeter can mean the difference between life and death.
Dr. Vitor Mendes Pereira performed the procedures alongside local principal investigator Dr. Anastasio Ameijeiras Sibauste. According to XCath, this marks only the second time a surgical robot has been used for intracranial neurovascular intervention. The company also claims its EVR platform is the only endovascular robotic system in development that has reached intracranial navigation or completed a neurointerventional treatment, and the first triaxial neurovascular robot to carry out a surgery.
The Scale of the Problem
Brain aneurysms are more common than most people realize. About 6.8 million Americans have an unruptured brain aneurysm—roughly one in 50 people, according to Brain Aneurysm Foundation data. The tricky part is that many show no symptoms or warning signs until the aneurysm ruptures.
The global picture is sobering. Ruptured aneurysms cause approximately 500,000 deaths worldwide each year. A large portion of these deaths occurs in individuals below the age of 50, with roughly half of all rupture cases proving fatal. For survivors, the road ahead is often difficult—close to two-thirds live with permanent neurological deficits of various kinds.
Precision at the Millimeter Level
XCath's clinical team guided the EVR robotic platform through fragile brain pathways with extremely fine control that reached below a single millimeter. Each case involved treatment devices from multiple manufacturers, with the physicians placing flow-related tools and intrasaccular implants through standard access routes throughout the entire session.
Two of the robotic sessions unfolded consecutively inside one operating room across a total window of roughly four hours. This sequence also created a world first for neurovascular robotics within a monoplane imaging environment, according to XCath.
Democratizing Elite Surgical Skills
"Neurovascular intervention for brain aneurysm requires operating with sub-millimetric precision, demanding exceptional control and consistency," Pereira said in XCath's statement. "With the success of these aneurysm procedures, XCath's system has demonstrated the potential to enhance human performance and bring a new level of precision to complex neurovascular cases."
Pereira elaborated that reliable robotic movements along with consistent execution may support the development of clinical skill across wider groups of physicians, which could create safer intervention pathways over time for difficult vessel work.
The Panama Clinic served as the host institution for these sessions, placing the center at the forefront of regional medical innovation as the team carried out this high-complexity work inside its neurovascular program.
"These procedures mark a pivotal milestone in the evolution of neurointerventional care and establish Panama as a leading strategic hub for the development of new medical technologies," Ameijeiras said. "By harnessing robotic capabilities, we can broaden global access to advanced neurovascular care and bridge care gaps stemming from geography and access."
Why Brain Surgery Remains So Difficult
Intracranial navigation presents extraordinary complexity due to the fragile and tortuous nature of the neurovasculature. That complexity has limited the number of physicians who can perform necessary maneuvers to a very small group of highly skilled neurointerventionalists, according to XCath.
The company's EVR system allows surgeons to place guidewires, catheters, and treatment devices throughout the intracranial vasculature with robotic precision. Think of it as giving a surgeon superhuman steadiness and control when working inside blood vessels narrower than a strand of spaghetti.
"Unlocking clinical and commercial value in neurointervention starts with making life-saving intracranial care more replicable, more precise, and more accessible when every minute counts," XCath CEO Eduardo Fonseca said. "This milestone is a testament to the passion and dedication of our robotics, clinical, and investor team."
Remote Surgery Capabilities
XCath's EVR system has both local and telerobotic capabilities. In May 2024, the XCath team successfully performed the world's first public demonstration of a simulated, remote mechanical thrombectomy, during which Pereira performed the procedure from Abu Dhabi on a simulated patient in South Korea.
The remote surgery capability could prove transformative for patients in regions without access to specialized neurovascular surgeons. If a small-town hospital can connect a patient to a top specialist thousands of miles away, geography becomes less of a barrier to life-saving care.
Founded in 2017, XCath operates campuses in Houston and Pangyo, South Korea. The company notes that its endovascular robotic system is currently under development and is not yet cleared for commercial distribution in any country.
