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