The Numbers

Approximately 795,000 Americans experience a stroke each year, with about 87% being ischemic strokes, underscoring the critical need for rapid and effective treatment solutions.
The golden hour for acute ischemic stroke treatment is often considered within 6 hours of symptom onset, but newer evidence supports extending the thrombectomy window to 24 hours for select patients, making device efficiency paramount.
Globally, stroke is the second leading cause of death and a major cause of long-term disability, highlighting the immense public health burden and the potential impact of advanced medical technologies.
The market for neurovascular devices, particularly mechanical thrombectomy, is projected to grow significantly, driven by an aging population and increasing awareness of stroke treatment options, positioning Penumbra for substantial expansion.
Clinical data supporting computer-assisted thrombectomy systems often demonstrates improved first-pass recanalization rates and reduced procedure times, directly translating to better patient outcomes and reduced hospital stays.
Penumbra's previous generation of aspiration thrombectomy devices has already treated hundreds of thousands of patients worldwide, establishing a strong foundation of trust and clinical efficacy within the neurointerventional community.

Context Check

Acute ischemic stroke occurs when a blood clot blocks an artery supplying blood to the brain, depriving brain tissue of oxygen and nutrients. Without immediate intervention, brain cells begin to die, leading to permanent neurological damage or death. The devastating impact of stroke necessitates swift and decisive medical action, making every minute crucial for preserving brain function and improving patient prognosis. Traditional treatments like intravenous thrombolysis (tPA) have limitations, particularly for large vessel occlusions, which often require mechanical thrombectomy.

Mechanical thrombectomy has revolutionized stroke care over the past decade, offering a highly effective method to physically remove clots from cerebral arteries. This procedure involves inserting a catheter into an artery, guiding it to the clot, and then using devices like stent retrievers or aspiration catheters to extract the blockage. While highly successful, the effectiveness and speed of these procedures can vary based on clot characteristics and operator experience, pointing to an ongoing need for technological enhancements that can standardize and optimize outcomes.

Despite advancements, significant challenges persist in acute stroke treatment. A substantial number of patients still do not receive timely or optimal care, often due to delays in presentation, misdiagnosis, or limitations in available resources and specialized expertise. Furthermore, some complex clot morphologies or tortuous vascular anatomies can make thrombectomy technically challenging, leading to longer procedure times or incomplete recanalization. These factors underscore the urgent demand for innovations like THUNDERBOLT that promise to streamline and improve the efficacy of these life-saving interventions.
