    摘要: The present invention comprises a device and method for targeted drug delivery, and especially intracranial inflsion or retroperfusion drug delivery using nonlinear magnetic stereotaxis in combination with magnetic resonance (MR) imaging and/or X-ray visualization. An MR-visible and/or X-ray visible drug delivery device is positioned by non-linear magnetic stereotaxis at a site such as an intracranial target site, its location is verified via MR imaging, and it is then used to deliver a biologically active material such as a diagnostic or therapeutic drug solution into that site (such as the brain) at constant or variable rates. The spatial distribution kinetics of the injected or infised drug agent may be monitored quantitatively and non-invasively using real-time MR-imaging such as water proton directional diffusion MR imaging, to establish the efficacy of targeted drug delivery.

    摘要: A method, technique and system is disclosed for the delivery of therapeutic agents and/or into the bulk brain tissues and other parts, tissues and organs of the body, including vasculature. A novel form of coaxial catheter provides a means for implanting an outer tube into the brain, then inserting an inner tube into the outer tube and aligning them such that port holes on both of the tubes will overlap and permit a flux of the therapeutic agent to flow into the brain in such a way as to minimize the effects of trapped air, virtually eliminate backflow of the agent, and avoid the potential for additional damage to the brain since only one surgical placement of the outer tube is needed. Similarly, the method, technique system may be utilized to remove fluids or other medium from the brain, tissues, and organs to minimize the effects of escaped air or negative pressure.

    摘要: A functionalized tip is incorporated into catheters for the cytometric delivery of cells into the brain and other body parts. For use in the brain, the tip forms part of a neurosurgical probe having a proximal end and a distal end. In addition to the functionalized tip, the probe has at least one cell slurry delivery lumen and a plurality of optical fibers configured along the probe, terminating in the tip to provide the photo-optical capability needed to monitor the viability and physiological behavior of the grafted cells as well as certain characteristics of the cellular environment. Details are also presented of the use of a neurocatheter having a cytometric tip of the type disclosed in the invention, as employed within the context of a feedback and control system for regulating the number of cells delivered to the brain of a patient.
