摘要:
An endovascular microvalve device for use in a vessel during a therapy procedure includes a catheter and a filter valve coupled to the catheters. The filter valve is dynamically reconfigurable to automatically block and permit fluid flow through a vessel based on a local fluid pressure conditions about the filter valve. In embodiments, the filter valve has a proximal end fixed to the catheter, and a distal end which may be movable over the catheter. The lumen of the inner catheter delivers a therapeutic agent beyond the valve. The device is used to provide a therapy in which a therapeutic agent is infused into an organ.
