Making a case for endovascular approaches for neural recording and stimulation

Area of Science:

• Neuroscience
• Biomedical Engineering
• Medical Devices

Background:

• Direct-contact electrodes for neural recording and stimulation require invasive surgery.
• Existing electrodes range from non-invasive scalp types to penetrating microelectrodes.
• Open brain surgery poses significant risks to patients.

Purpose of the Study:

• To review the development and application of endovascular electrodes.
• To compare the efficacy of endovascular electrodes with direct-contact electrodes.
• To present potential clinical applications and advantages of endovascular approaches.

Main Methods:

• Review of existing research on endovascular electrode development and application.
• Comparative analysis of endovascular and direct-contact electrode capabilities.
• Discussion of clinical applications and benefits of minimally invasive techniques.

Main Results:

• Endovascular electrodes can be delivered via catheterization, reducing surgical risk.
• Comparison demonstrates the relative efficacy of different endovascular electrode types.
• Potential clinical applications highlight the advantages over direct-contact methods.

Conclusions:

• Endovascular electrodes represent a promising, less invasive alternative for neural interfacing.
• Minimally invasive endovascular approaches mitigate risks associated with traditional brain surgery.
• Further research and development can expand the clinical utility of these devices.
