Embolic compositions for treating vascular defects such as aneurysms include a mixture of a biocompatible polymer material, a biocompatible solvent, and preferably also an adhesive. The compositions preferably further comprise magnetic particles for controlling the delivery of the embolic agent. These magnetic particles preferably lose magnet strength over time, so that they do not interfere with subsequent magnetic diagnostic and therapeutic procedures. The compositions preferably also include radiopaque particles, which may be the magnetic particles, to facilitate imaging the embolic material.
