INTERNAL COMPRESSION TREATMENT (ICT)

Abstract

A system related to the reparation of damaged veins along with the suspension of venous stasis progression by minimizing the leak reflux flow and the protection of the valve functions of the vena saphena magna, parva, perforator veins by means of exovascular or external filling agent injection in the treatment of venous stasis (which is also called varicose vein or varicose treatment).

Claims

2. The internal compression system according to claim 1, wherein the filling agent is selected from the group consisting of n-butyl cyanoacrylate, butyl 2-cyanoacrylate, octyl cyanoacrylate, octyl 2-cyanoacrylate, octa-butyl cyanoacrylate, ethylene vinyl alcohol, Botulinum toxin, ethylene vinyl alcohol-co-polymer-DMSO and mixtures thereof.

3. The internal compression system according to claim 2, wherein the internal compression system comprises hyaluronic or gluconic acid as a connective tissue enhancer.

4. The internal compression system according to claim 3, wherein the internal compression system comprises 1 unit of hyaluronic acid and 2 units of cyanoacrylate.

5. The internal compression system according to claim 3, wherein the filling agent comprises 1 unit of hyaluronic acid and 3 units of cyanoacrylate.

6. The internal compression system according to claim 1, wherein the echogenic rigid catheter is a catheter having a diameter of 4F, 5F, 6F, 7F, and 8F and the echogenic rigid catheter contains PTFE, polyether block amides (pebax), PE, a metal, or is made of a metal.

[0007] FIG. 1: Application method of the filling agent

DETAILED DESCRIPTION

[0008] The invention is composed of 2 main elements. A biocompatible filling agent such as biocompatible cyanoacrylate (n-butyl, n-butyl-2, octyl, octyl-2 or octa-butyl cyanoacrylates), hyaluronic acid, ethylene vinyl alcohol copolymer DMSO, Botulinum toxin between 0-1000 cps density (suggested density is 75-100 cps) and an echogenic and rigid catheter custom-engineered for this procedure. For example, 1 unit of hyaluronic acid and 2 units of cyanoacrylate can be used in the filling agent.

[0009] A percutaneous entrance is made under ultrasonographic imaging with the help of a needle into the vein trace between the muscle fascia and the target vein planned to be treated. The trace is expanded by making a small amount of liquid injection with a liquid such as dextrose solution or physiological saline solution between the vein and the muscular layer named fascia. A rigid guide is pushed towards the target segment through the same needle. For this procedure, a catheter comprising stainless steel (SS) or nitinol coil reinforced PTFE hydrophilic coating is pushed into the procedure area through the guide wire by withdrawing the needle. A biocompatible filling agent such as biocompatible cyanoacrylate, hyaluronic acid, Botulinum toxin between 0-1000 cps) density suggested density is 75-100 cps) is injected exovascularly (extravascular) onto the problematic valve segments of the venous structures in which venous stasis is present, such as the saphenous vein, popliteal vein, perforator vein by means of the catheter under ultrasound until the leak reflux flow decreases between the range of 0.5-1 sec. In order to monitor the maximum vein diameter during injection, the patient needs to hold his/her breath and strain. The treatment is completed after making the necessary trace and valve checks at the end of the procedure. In this procedure, the treatment is applied not only to a single part of the vein segment, but to the entire problematic segment across the trace.

[0010] In a sample application, the fascia is opened by applying dextrose between the fascia and the vein by means of the catheter and the guide wire is pushed through this opening. Connective tissue enhancing drugs such as hyaluronic acid, gluconic acid can be used in order to reinforce the filling agent and repair the muscle. The filling agent should be injected with a pressure less than 10 mm hg pressure. It can be used in all venous system leaks. Vena saphena magna, parva, perforator vein leaks, deep venous insufficiency, primary deep venous insufficiency are examples. Indicators may be present on the application catheter.
