Leveraging Interventional Radiology Techniques for Minimally Invasive Neuromodulation.

Area of Science:

• Medical Devices
• Interventional Radiology
• Neuroscience

Background:

• Neurostimulators offer potential for treating various diseases, including hypertension and chronic pain.
• Current neurostimulator implantation often requires open surgery, limiting applications and adoption due to invasiveness.
• Interventional radiology provides minimally invasive approaches to overcome surgical limitations.

Purpose of the Study:

• To explore the application of interventional radiology techniques for minimally invasive neurostimulation.
• To highlight advancements in device design facilitating neurostimulator implantation.
• To discuss the potential of these approaches for autonomic system therapies.

Main Methods:

• Utilizing percutaneous, endovascular, or port-based access guided by advanced imaging (CT, MR, fluoroscopy, angiography).
• Employing miniature electrodes and stimulators for precise targeting of deep nerves, nerve branches, and plexuses.
• Leveraging concurrent advances in wireless power, miniaturized packaging, and novel interface designs.

Main Results:

• Minimally invasive techniques enable precise targeting of deep and small-diameter nerves, previously inaccessible.
• Selective nerve modulation with reduced side effects is achievable through accurate electrode placement.
• Advancements in device technology support the development of injectable and stent-like neurostimulator interfaces.

Conclusions:

• Interventional radiology is crucial for advancing minimally invasive neurostimulation therapies.
• Miniaturized devices and innovative implantation techniques enhance the feasibility and safety of neurostimulation.
• These approaches hold significant promise for treating autonomic system disorders and other conditions.
