Endovascular Neuromodulation: Safety Profile and Future Directions

Area of Science:

• Neurology
• Neural Engineering
• Biomedical Devices

Background:

• Endovascular neuromodulation merges interventional neurology and neural engineering.
• The Stentrode is a stent-electrode array for endovascular neural interfaces.
• Conceptual validation exists in ovine models, but human data is lacking.

Purpose of the Study:

• To review existing literature on transvenous leads.
• To identify potential risks and research needs for the Stentrode.
• To optimize the Stentrode for human application.

Main Methods:

• Literature review of transvenous lead devices.
• Analysis of safety and long-term viability data.
• Comparison with cardiac pacemaker/defibrillator lead literature.

Main Results:

• Technical precedence for venous sinus stenting exists for other conditions.
• Long-term intracranial venous lead implantation is novel.
• Cardiac device literature offers insights into potential risks and management.

Conclusions:

• Further research is needed to ensure the Stentrode's long-term safety and viability in humans.
• Lessons from cardiac device implantation are crucial for optimizing endovascular neuromodulation.
• Addressing potential risks is key for successful human application.
