Endovascular BCI Market: Stentrode Motor Cortex Access Demand, ALS and Paralysis Patient Population Growth, and AI-Based Signal Decoding Adoption to Drive Strong Market Expansion Through 2035

The global Endovascular BCI Market is projected to expand at a strong CAGR of 17.8% through 2035, driven by sustained clinical demand for minimally invasive stent-electrode access to the motor cortex, growing patient population needs across amyotrophic lateral sclerosis and severe paralysis indications, and continued adoption of AI-based neural signal decoding methodology. Given data limitations in the underlying source figures for this specific sub-segment, this brief presents the CAGR-based growth outlook without specific market size figures. The market comprises the commercially pioneering Stentrode system alongside a growing pipeline of investigational endovascular neural interface devices applied across severe motor impairment indications.

The market’s strong 17.8% CAGR reflects growing clinical recognition of endovascular delivery as a minimally invasive alternative to open craniotomy-based BCI implantation, generating structured demand from neurosurgery and neurology centers above discretionary medical device demand growth. The stent-electrode array delivered through the vascular system to the superior sagittal sinus and cortical veins represents the category’s defining technical approach, avoiding the surgical risks associated with direct cortical implantation. Sustained clinical trial activity across amyotrophic lateral sclerosis, spinal cord injury, and stroke-related paralysis continues to anchor demand, while continued advancement of AI-based decoding technology supports translation of recorded neural signals into functional communication and device control outcomes. Coverage extending across multiple device architectures, implantation approaches, and control functions underscores the breadth of clinical development infrastructure now supporting this category.
