Abstract
An endovascular valve device for use in a vessel during a therapy procedure includes a catheter having at its distal end a valve. The valve is constructed of a braid of elongate first filaments coupled together at their proximal ends in a manner that the first filaments are movable relative to each other along their lengths. The first filaments have a spring bias that radially expands the valve. A filter is provided to the braid formed by electrostatically depositing or spinning polymeric second filaments onto the braided first filaments. The lumen of the catheter is in communication with the center of the valve. The device is used to provide a therapy in which a therapeutic agent is infused into an organ.
