ARPA‑H has granted Siemens Healthineers a substantial multi‑year award to accelerate the creation of autonomous, remote endovascular robotics, a technology envisioned to reshape the treatment paradigm for acute ischaemic stroke across the United States and eventually worldwide. The initiative is anchored in the agency’s Autonomous Interventions and Robotics (AIR) program, which is overseen by program manager Ileana Hancu, whose leadership is guiding the effort toward a new generation of self‑directed neurovascular interventions.
Siemens Healthineers will pair the $31.1 million federal award with its own $5.4 million cost‑share contribution, bringing the total financial commitment to up to $36.5 million—a figure that shows the strategic importance placed on this emerging field. The collaboration is further strengthened by the involvement of Stryker as a sub‑awardee, a role that builds directly on the strategic partnership the two companies forged in 2025 to fast‑track advances in robotic neurovascular care.
According to Siemens Healthineers, the convergence of precision endovascular robotics, advanced image guidance, and purpose‑built devices is poised to redefine how neurovascular procedures are performed. By integrating these elements, the company anticipates a future in which clinicians can rely on highly automated platforms to execute complex interventions with enhanced accuracy and consistency.
Philipp Fischer, Head of Advanced Therapies at Siemens Healthineers, emphasized the significance of the ARPA‑H investment, describing it as a major step forward for autonomous remote endovascular robotics that will benefit patients and communities around the globe.
The core of the technology under development is a robotic system capable of conducting long‑distance mechanical thrombectomy without the need for a physician to be physically present at the bedside. Mechanical thrombectomy itself is a minimally invasive technique that extracts a clot from a blocked cerebral artery, restoring blood flow and dramatically improving the odds of neurological recovery when performed swiftly after stroke onset.
It is important to recognize that this autonomous remote solution is still in the research and development phase and has not yet entered the commercial market. The ongoing work focuses on refining the robot’s ability to handle the vascular network, integrate real‑time imaging data, and execute clot‑removal maneuvers with a level of autonomy that reduces reliance on immediate human manipulation.

Access to mechanical thrombectomy remains highly concentrated in full stroke centres, leaving a large segment of the population without timely availability of this life‑saving procedure. Geographic distance to capable facilities and the limited number of centres equipped to perform the intervention create a pronounced disparity in care, as many patients experience delays that diminish the therapeutic window.
By enabling a robot to operate remotely, the project seeks to extend the reach of thrombectomy capabilities to hospitals that lack on‑site expertise. This model could allow specialists to direct procedures from a central hub, effectively turning any suitably equipped interventional suite into a potential stroke‑treatment site and thereby narrowing the current access gap.
The combined investment from public and private sources reflects a deep commitment to overcoming the logistical and technical barriers that have historically constrained stroke care. Over the next several years, the partnership will focus on iterative testing, validation of autonomous decision‑making algorithms, and integration of cutting‑edge imaging modalities to ensure that the robot can respond to the dynamic environment of the cerebral vasculature.
Anticipated outcomes include faster door‑to‑reperfusion times, reduced reliance on scarce specialist travel, and a broader distribution of high‑quality stroke treatment that could lower the incidence of long‑term disability. By addressing both the technological and systemic challenges, the initiative aims to create a scalable solution that benefits patients irrespective of their location.
As the development program progresses, the collaboration between Siemens Healthineers, Stryker, and ARPA‑H will continue to leverage interdisciplinary expertise, from robotics engineering to neurovascular clinical practice. The joint effort embodies a forward‑looking strategy to translate advanced research into tangible clinical tools that enhance emergency stroke care and set new standards for remote medical interventions.
