Abstract:
A method of delivering a material selected from the group consisting of drug agent and diagnostic agent by selective infusion or retroperfusion comprising the steps of:a) positioning a delivery device by a process selected from the group consisting of nonlinear magnetic stereotaxis and intra-operative magnetic resonance imaging-based guidance;b) verifying the location of said device via magnetic resonance (MR) imaging, andc) delivering said material by infusion or retroperfusion through said delivery device with real time visualization of said delivering via magnetic resonance imaging;wherein said verifying is done after positioning of said delivery device, and delivering said material is performed after verifying the location of said delivery device, wherein after said delivery of said material, magnetic resonance imaging visualizes the movement of said material through tissue, and wherein after visualizing the movement of said material through tissue, magnetic resonance imaging is temporarily halted, said delivery device is repositioned, and magnetic resonance imaging is restarted.
