    摘要: A system for delivering therapeutic agent to a target location in a body in accordance with one embodiment is provided comprising a plurality of magnetic particles, each magnetic particle carrying a therapeutic agent, and a magnetic device for attracting the magnetic particles to a target location. The magnetic particles may be delivered by a catheter into a blood vessel upstream from the target location so that they travel toward the target location. A method for delivering therapeutic agent to a target location in a body in accordance with another embodiment comprises providing a plurality of magnetic particles, each magnetic particle carrying a therapeutic agent, placing a magnetic device in a position to attract the magnetic particles to a target location, and allowing the magnetic particles to infuse the target location by the attraction of the magnetic particles to the magnetic device. The therapeutic agent may comprises a therapeutic agent for preventing or treating reperfusion injury, and the step of providing the plurality of magnetic particles may comprise delivering the plurality of magnetic particles through a blood vessel.

    摘要: Devices and methods to cool a target tissue region inside the body are described. Fluid cooled below normal body temperature and blood at a normal body temperature are provided to the tissue region in proportions to cool the tissue region. A system for controlling the temperature of the target tissue region is disclosed. The system includes a catheter and a control system that controls the amount of cool fluid and blood provided to the tissue region. A catheter for providing cool fluid to the tissue region is also provided. The catheter includes a temperature sensor that extends to a location distal to the distal end of the catheter to sense the temperature of the tissue region.
