Embodiment Construction

[0025] Systems, methods and devices for minimally invasive treatment of varicose veins and other medical conditions are disclosed herein. As used herein with respect to a device, proximal may refer to an access insertion site toward an access vessel, while distal refers to a direction away from an access insertion site and along a patient. In some embodiments, the occlusion device is deployed to occlude the saphenous vein just distal to the superficial femoral junction (SFJ) and is formed into a flattened shape so that the vein can be further treated with either substance to alter the vein, thereby preventing occlusion in conditions such as sclerosing solutions or Blood flow in medical adhesives. In some embodiments, complete venous occlusion is a desired clinical outcome of all treatments that alleviate the effects of venous hypertension caused by degenerative venous flow. The occlusive device and medical adhesive can be delivered through the catheter using a "single rod" ap...

Abstract

Methods, devices and systems are described for treating venous insufficiency in which the vein is compressed at least partially along a treatment zone. A system can be provided including an injection device (300), such as a glue gun, that is operably connected to a delivery catheter (202) that can be advanced across a treatment zone in the vein (400). The delivery catheter can be used to deliver one, two, or more boluses of media (V2, V2') (e.g., cyanoacrylate) to occlude the vein (400) along different spaced-apart sections of the treatment zone. External compression can also be applied to the vein (400) by a compression element, such as a hand (640) or multifunctional ultrasound transducer (630), to occlude portions of the vein (400) along the treatment zone prior to or during the introduction of the boluses of media (V2. V2').

Description

[0001] priority claim [0002] This application claims priority under 35 U.S.C. § 119(e) to U.S. Provisional Application No. 61 / 154,322, filed February 20, 2009, and U.S. Provisional Application No. 61 / 285,926, filed December 11, 2009 right. The entire content of said prior application is incorporated herein by reference. Background technique [0003] Healthy leg veins contain valves that allow blood to flow in one direction from the lower extremity toward the heart. As blood flows toward the heart, these valves open and close to prevent venous backflow, or the backward flow of blood. When veins weaken and become enlarged, their valves do not close properly, which causes venous backflow and impairs the drainage of venous blood from the legs. Venous reflux is most common in superficial veins. The largest superficial vein is the saphenous vein, which runs from the top of the foot to the groin, where it arises from a deep vein. [0004] Factors that can lead to venous reflux...
