摘要: A magnetic resonance imaging (MRI) guided surgical system is provided that includes one or more surgical tools having components configured to develop reactive effects when exposed to MR signals generated by the MRI system. The system includes a control system that can determine whether the MR system is generating MR signals, and if the control system determines that the MR system is generating MR signals, mitigates the reactive effects of MR signals on components of the surgical tools. The system can include a cryoablation system with a cryoprobe having a probe shaft being made of a metallic material. If the control system determines that the MR system is generating MR signals, the control system can electrically disconnect the cryoprobe and/or ignore electrical signals generated by the electric heater in response to exposure to MR signals, and/or initiate a cooling operation of the probe shaft, whereby the cooling operation.

摘要: This invention concerns imageable, radiopaque embolic beads, which are particularly useful for monitoring embolization procedures. The beads comprise iodine containing compounds which are covalently incorporated into the polymer network of a preformed hydrogel bead. The beads are prepared by activating pre-formed hydrogel beads towards nucleophilic attack and then covalently attaching iodinated compounds into the polymer network. The radiopaque beads may be loaded with chemotherapeutic agents and used in methods of embolizing hyperplastic tissue or solid tumors.

摘要: A method of distributing microparticles is provided, the method comprising: providing a plurality of microparticles at an insertion site in a medium; applying ultrasound to the insertion site that generates gas bubbles by cavitation at cavitation nuclei located at the insertion site and drives movement of the gas bubbles such that the gas bubbles drive movement of the microparticles into a desired spatial distribution in the tumour. The method may be a method of treating a tumour, and the microparticles may comprise a radioisotope for treating the tumour. Microparticles for use in the treatment of a tumour by the method are also disclosed.
