Abstract: An apparatus for stimulating regeneration and repair of damaged spinal nerves, comprising at least two electrodes placed intravertebrally near the site of spinal neurite injury and delivering direct current thereto. A method for stimulating regeneration and repair of damaged spinal nervous tissue, comprising placing electrodes intravertebrally near the site of spinal cord injury and applying direct current at a level sufficient to induce regeneration and repair of damaged spinal neurites but less than the current level at which tissue toxicity occurs.

Abstract: A self-inflating and self-deflating orally ingestible device that is able to traverse the entirety of the alimentary canal is described. In one embodiment, the device includes a closed balloon having a surface separating an enclosed space internal to the balloon from a space external to the balloon, at least one self-sealing valve integrated with the surface of the balloon to provide access to the enclosed space internal to the balloon from the space external to the balloon, a vent comprised of a dissolvable seal integrated with the surface of the balloon, and a vessel located within the enclosed space internal to the balloon to separate internal contents of the vessel from the enclosed space internal to the balloon.

Abstract: A self-inflating, intragastric balloon device is activated by addition of an activating liquid into an acid or water soluble vessel located within the balloon. After an approximately pre-determined time period post-activation, the activating liquid breaches the vessel wall and causes contact between an acid in liquid form and an emissive substance within the balloon, causing it to inflate. The device is conveniently provided to medical personnel as part of a kit that further contains a syringe and the activating liquid. The device also can have acid or pepsin degradable portions that cause it to deflate after residing in the stomach for a prolonged period of time during which it imparts a feeling of satiety in the patient.

Abstract: A dynamic system adapted to test a patient to determine the degree to which his physical stability is impaired and therefore predisposes the patient to injurious falls. The system includes an unsteady platform supported at a raised position above ground and free to rock about a horizontal X-axis and about a Y-axis which intersects the X axis at the center of the platform and is normal thereto so that the orientation of the platform is changeable relative to these axes. Mounted on the platform are electronic clinometers that yield signals which are a function of the deviation of the platform from the horizontal X and Y axes and therefore depend on the changing orientation of the platform when a patient to be tested stands thereon. These signals are fed to a computer whose output is applied to a video monitor having a display screen on which is presented a cursor the position of which is controlled by the signals.

Abstract: A dynamic system adapted to test a patient to determine the degree to which his physical stability is impaired and therefore predisposes the patient to injurious falls. The system includes a stable platform yielding signals that depend on the magnitude and direction of the force applied to the face of the platform. The platform is rendered unsteady by a convex rocker dish resting on the the platform face and having a flat top on which the patient stands. The resultant signals which are a function of the changing orientation of the flat top of the dish relative to the platform face are fed to a computer whose output is applied to a video monitor having a display screen on which is presented a cursor whose position is controlled by the signals.
