LGO-Vena Introducer Set
The area of application for the LGO catheter system is the minimal invasive treatment of the insufficient Greater Saphenal Vein and was particulary developed for this purpose. All components necessary for the operation are packed and kept together in a sterile bag.
The catheter is intended for to introduction into the Greater Saphenal Vein (in Seldinger technique). The canula provided in the set is used to puncture the vein and for the introduction of the guide wire, which is also contained in the set.
Markings in the distance of 1 cm make it easy to see the Insertion length. An adapter is attached to the laser fiber (LGO-Bare Fiber 600 µm), which is used to lock to fiber to the catheter and thus the fiber is distally 1 cm longer than the catheter.
An irradiation of the catheter is prevented.
The LGO-Vena Introducer set is a single use device.
Endovenous Laser Treatment (EVLT) of the vena saphena magna and parva:
First the trace of the vein and the position of the saphenofemoral junction is determined by ultrasound (fig 1)
After the percutaneous punction of the vein the physician introduces a thin Caretron litenife optical fiber through a catheter (fig 2) to bring it next to the saphenofemoral junction (fig 3). A visible red aiming beam indicates the position of the fiber tip.
A locally applied tumescent anesthesia prevents (fig 4) an injury of adjacent tissue and has a positive effect on the post-operative pain development
After the ultrasonic position control the laser irradiation starts (fig 5). The laser radiation causes a well-defined thermal damage of the Intima, which results in a thrombose in the vein and thus closes it. The laser is independent of the diameter of the vein and globally applicable, since a contact of the fiber to the vein wall is not necessary. The controlled damage of the Intima caused indirectly by the heated blood.
After only 30 to 45 minutes the treatment is completed.
