AI Technical Summary

Technical Problem

Existing medical devices for treating defective blood vessels, such as varicose veins, require substantial space within the vessel, causing vein wall damage and spasms, and necessitate multiple painful external anesthetizations, with existing methods being technically complex and inefficient.

Method used

A medical device with a hollow shaft and elongated holding device featuring curved holding elements that radially secure a treatment device, allowing for precise deployment of tumescent fluid and minimizing vein wall contact, combined with a method for internal anesthetization to reduce pain and simplify treatment.

Benefits of technology

The device enhances treatment accuracy and reduces postoperative pain by forming a protective fluid layer around the vein, stabilizing the treatment, and enabling repeated anesthetization without vein wall damage.
