    摘要: A catheter for administering a substance into body tissues includes an elongated catheter body that has at least one portion of the length of the catheter body that expands after the catheter is inserted in the patient's body. The portion that expands provides a seal against backflow of the substance along the outer surface of the catheter body and away from the intended treatment area.

    摘要: A system and method for treating Amyotrophic Lateral Sclerosis (ALS) by delivery of an agent within the brain. At least one image of a target region is acquired, and at least one magnetic resonance diffusion tensor imaging (MR-DTI) scan of the target region is acquired. A diffusion tensor is calculated from the at least one MR-DTI scan, and at least one of an agent distribution and an agent concentration from the images and the calculated diffusion tensor is calculated. Using at least one of the calculated diffusion tensor, the images, the calculated agent distribution, and the calculated agent concentration, the placement of a delivery instrument is planned to deliver the agent to the target region to achieve a desired agent concentration and/or agent distribution within the target region.
