Endoluminal radiofrequency elimination targets varicose veins.
The method uses radiofrequency current generated heat that can warm up tissues as much as 180 degrees F. The technology is not new. It uses the same radiofrequency current that has been used for decades in general surgery to cut tissues and coagulate (seal off) small blood vessels. In the last 10 to 15 years the technology has been used in cardiology to treat several forms of rhythm disturbances refractory to medical management.
When connective tissue is heated, it shrinks. This shrinking is the direct result from heat’s impact on collagen, a fibrous protein that composes 90% of the organic material of all tissues, including veins. When collagen is heated, the bonds that keep the spring-like substance taut are released, and the collagen spring shrinks into a jumbled coil that shrivels the tissue. The probe (catheter) introduced into a vein under local anesthesia, closes the vein without surgery.
