摘要：
A therapeutic agent delivery system includes a catheter, a vascular occluder, a pressure sensor system, and a pump system. The vascular occluder is provided at the distal end of the catheter. The pressure sensor system is provided to sense pressure at the distal end of a catheter lumen, and provides feedback to the pump system. The pump system is adapted to control the rate of infusion of the therapeutic agent through the lumen of the catheter based on the pressure sensed by the pressure sensor system. A method includes deploying the occluder in a vessel, and then sensing a pressure in the vessel. The therapeutic agent is infused into the vessel at a flow rate based on the sensed pressure.
