Immediately detachable coil for aneurysm treatment

Area of Science:

• Biomedical Engineering
• Medical Devices
• Interventional Radiology

Background:

• Cerebral aneurysms pose significant risks, necessitating effective endovascular treatment options.
• Current endovascular coils require complex detachment mechanisms, impacting procedure time and reliability.

Purpose of the Study:

• To develop and evaluate a novel endovascular coil with an instant electrical detachment system.
• To assess the reliability of this new detachment system in treating experimental aneurysms.

Main Methods:

• Development of an endovascular coil featuring a polyvinyl alcohol junction.
• Utilizing high-frequency electrical current to disrupt the junction via heat for rapid detachment.
• Testing the detachment system's reliability in experimental aneurysm models.

Main Results:

• The endovascular coil detached instantly upon application of high-frequency electrical current.
• The polyvinyl alcohol junction disruption occurred within one second.
• The detachment system demonstrated reliability in the treatment of experimental aneurysms.

Conclusions:

• The developed endovascular coil with an electrical detachment system offers a rapid and reliable solution for aneurysm treatment.
• This technology has the potential to improve the safety and efficiency of endovascular procedures.
