AI Technical Summary

Technical Problem

Conventional methods for treating pain by embolizing abnormal capillaries are complex, requiring precise judgment and skilled techniques, specialized equipment, and a long procedure time.

Method used

Administer a particulate embolic material with a size of 10 μm to 200 μm into the main artery nourishing the painful area while constraining the upstream and/or downstream blood flow, using a tourniquet to control blood flow and block abnormal capillaries.

Benefits of technology

This method simplifies the pain treatment process by efficiently blocking abnormal capillaries without the need for precise judgment or specialized equipment, reducing procedure time and ensuring effective pain relief.

Abstract

To provide means for pain treatment capable of being performed easier by embolizing an abnormal capillary.SOLUTION: The present invention is an agent for pain treatment. The agent for pain treatment contains a particulate embolic substance having an average particle size of 10 μm or more and 200 μm or less. The agent for pain treatment is used by injection into a major artery that supplies nutrients to a painful area. The agent for pain treatment is administered in a state where the upstream and / or downstream of blood flow, with respect to an administration site is avascularized.SELECTED DRAWING: None
