When Speed and Precision Matter

Clot extraction (thrombectomy) is a critical procedure for stroke patients, achieving technical success rates above 90 percent. However, while thrombectomy effectively removes the clot, it does not address the underlying damage to the brain tissue caused by one, the disrupted blood flow to the brain (ischemia) from the blockage of the brain artery by the clot and two, the secondary damage caused by reperfusion injury. Reperfusion injury is caused by the sudden inflow of blood following the reopening of a clogged brain artery and is largely an inflammatory response accompanied by oxidative stress that exacerbates brain damage. As a result, less than 20 percent of patients experience a full recovery.

Therapeutic hypothermia is a well-known neuroprotective strategy that slows metabolism and reduces cell death through multiple protective mechanisms. Yet, systemic (whole body) cooling in stroke patients is often too slow and carries risks such as shivering, cardiovascular instability, infection, and immune suppression. In fact, it typically takes many hours to reduce body and brain temperatures by a few degrees Celsius—a complex undertaking which is often unsuccessful. These limitations make it impractical as a neuroprotective treatment for stroke. In contrast, selective endovascular brain cooling offers a promising alternative by delivering rapid, targeted hypothermia directly to the affected brain tissue. This method achieves protective brain tissue temperatures within minutes without compromising overall body function or introducing widespread systemic complications.

Hybernia Medical is positioning itself at the forefront of this innovative approach. The company has developed a catheter-based system designed to provide localized brain cooling immediately following thrombectomy. This solution works within minutes, cooling the targeted brain tissue directly through a catheter introduced via the same arterial pathway used during clot extraction.

“We developed a device that cools the brain directly through a catheter system in a highly selective, precise, and fast manner,” says Jae Choi, co-founder and CEO.
The approach is built on years of rigorous research and development, evolving through extensive tests and large-animal studies and building on numerous preclinical stroke experiments that have validated both its safety and feasibility. Early clinical signals suggest that when combined with thrombectomy, localized cooling could lead to significantly improved outcomes.

Beyond the cooling mechanism itself, Hybernia Medical’s system is engineered with advanced technology to ensure optimal performance. Embedded sensors provide real-time feedback that allows the device to adjust dynamically to the patient’s anatomical and physiological environment. This intelligent design ensures that the cooling process is not only effective but also consistent and safe. The infusion system that drives the cooling process has been optimized for maximum efficiency by using minimal fluid volumes—down to a fraction of a milliliter—which enhances heat transfer at the tissue level without jeopardizing patient safety or causing systemic instability.

The targeted nature of this technology mirrors established practices in other areas of medicine. Just as ice packs are routinely used to manage sports injuries or fever, localized cooling here offers a precise tool for clinicians aiming to minimize stroke-related brain damage at the point of care. By concentrating the therapeutic effect where it is most needed, Hybernia Medical’s innovation represents a crucial evolution in stroke treatment, one that goes beyond merely restoring blood flow to actively protecting vulnerable brain tissue.

With recognition and funding from prominent institutions such as New York State, the NIH, and the Dana Foundation, and the upcoming launch of the clinical study phase Hybernia Medical is well-positioned as a leader in localized cooling technology. Their work addresses a long-standing clinical challenge: how to reduce brain damage following a stroke. The company’s commitment to merging neuroprotection with technological precision underscores its mission to improve stroke outcomes worldwide. Ultimately, this innovative approach aims to help stroke patients not only survive the initial event but also regain meaningful independence and a better quality of life.

By refining the intervention process and introducing a novel therapeutic approach that targets adverse brain metabolic processes, Hybernia Medical continues to set a new standard in stroke care—a standard that is both rapid and highly targeted, promising a transformative impact on patient recovery.
