Paclitaxel eluting balloon catheter has a rapid Exchange (RX) design, developed for dilatation by balloon of stenotic portions in coronary arteries or stenosis after bypass grafts which replace coronary arteries. Small vessels can also be treated, as well as residual stenosis after balloon treatment or endoprothesis, and also pre/post-dilatation of endovascular coronary prothesis, with the aim of improving myocardial perfusion. Specially designed for percutaneous transluminal angioplasty (PTA) of coronary arteries. The catheters body has a configuration of simple proximal lumen and distal double lumen: The simple lumen is constituted by a hypotube which provides high pushability and allows passage to the inflation liquid from the luer connector to the balloon The double coaxial lumen has two functions: Inner lumen for guide wire passage (máximum diameter 0.014) Outer inflation lumen with straight connection to the hypotube
