    摘要： A prodrug according to formula (I) wherein R2 is a residue of a drug, said drug having a hydroxyl group by which the COOR2 group is formed; Z is O or NH; m is 0 or 1; and R3 is an organic moiety comprising a lipophilic group or a residue of a polymer, provided that Z is 0 if the polymer is carboxymethyl dextran. A system includes a plurality of magnetic nanoparticles including a prodrug as described above, a stent and a source of uniform magnetic field capable of producing temporary magnetization of the stent and/or the magnetic nanoparticles. A method of treating a medical condition with a drug includes administering to a patient in need of the drug a prodrug as described above, the prodrug being capable of releasing the drug in the patient after the administration step.

    摘要： A treatment system includes a magnetic targeting catheter and a plurality of MNP. The MNP may include one or more magnetic field-responsive agents and one or more therapeutic agents. The catheter may include an inner shaft having at least one lumen and a fluid delivery balloon adapted to administer a fluid from the inner shaft into a space surrounding the catheter. An expandable mesh formed of a magnetizable material may surround the fluid delivery balloon. The catheter may further include one or more occlusion balloons for controlling blood flow through a vessel in which the catheter is placed. A method of treating a medical condition may include advancing a magnetic targeting catheter to a site, deploying an expandable mesh connected to the catheter, applying a magnetic field to the mesh and depositing a plurality of MNP or cells loaded with MNP near the mesh.
