TriVex System offers new, safer, more effective treatment to people who
suffer from Varicose Veins. It was developed by Smith & Nephew, Inc., Endoscopy
Division, in conjunction with, a leading general surgeon.
Many patients resist treating their varicose veins because they are afraid of the
pain and recuperative time involved with surgery. The Trivex System offers patients a
minimally invasive treatment that lets them walk out of the hospital with few scars and be
virtually pain-free within a couple of weeks.
The TriVex System is designed for use during a patented, clinically tested surgical
technique for varicose vein removal called transilluminated power phlebectomy.
(Transilluminated means that light is passed through the skin and phlebectomy is the
medical term for vein removal.) In this procedure, the surgeon views the vein using a
transilluminating light and removes it with a small powered surgical device.
While traditional varicose vein surgery is a "blind procedure," meaning
that surgeons cannot always see the vein or confirm removal, The TriVex System's unique
illumination feature allows the surgeon to quickly and accurately target and remove the
vein and then visually confirm its complete extraction. This new process makes varicose
vein removal more effective, complete and less traumatic for patients, by reducing the
number of incisions required to perform the procedure and the duration of the surgery.
Studies suggest that this method not only reduces the pain associated with varicose vein
removal but also reduces the potential post-operative infection.
The procedure is performed on an outpatient basis and usually takes less than an
hour. In one study comparing results from minimally-invasive surgery to those obtained
with the older technique of hook phlebectomy, the minimally-invasive procedure cut
operating time in half, reduced the number of incisions by 50 to 75 percent, required less
anesthesia and caused less post-operative pain than the older surgery.
