    摘要: Methods are utilized for connecting electrically conductive wire to a miniature, implantable sensor or stimulator device for detecting electrical signals or stimulating living tissue. The implantable device has an electrically conductive end on its case which is intimately connected to a doorknob electrode for communicating electrical signals between the living tissue and the device by a biocompatible wire. A spring clip removably attaches to the doorknob electrode so that the wire may be easily attached to the doorknob electrode during surgery. An insulating rubber boot, which may be silicone, surrounds the case end, doorknob electrode, and spring clip to isolate the living tissue from the conductive components. The components are all biocompatible materials.

    摘要: A magnetic control system for selectively enabling/disabling an implantable device's operation using externally applied pulsed magnetic means, e.g., a controlled electromagnet or the like. Typically, such implantable devices stimulate a neural pathway or muscle and/or block pain or muscle stimulation according to programmable settings. Preferably, once programmed from an external programmer, such implantable devices can operate “independently” using the externally provided programmed information. However, in certain circumstances, it may be desired to stop/pause the operation of such selected implanted device while not affecting other such devices. Accordingly, embodiments of the present invention include a magnetic sensor, preferably a magnetoresistive, Hall effect, saturated core reactors, or the like, to sense an externally provided magnetic field. By externally applying pulsed magnetic fields in sequences of controlled polarities, durations, intensities, etc., and sensing these identifiable sequences and transitions, the operation of the implantable device may be enabled/disabled.

    摘要: Battery driven voltage control circuitry charges an output capacitor, which periodically supplies a current pulse. The circuitry converts battery voltage VBAT to a charging voltage VUPC based upon programmed parameters and the voltage VCOMPL at the capacitor. The circuitry includes a voltage converter for multiplying VBAT to produce VUPC. VCOMPL is sampled to determine its “droop” at the end of an output current pulse. If the droop is lower than a threshold, then the voltage converter increases the charging voltage. If the droop is above a threshold, then the voltage converter reduces the charging voltage. This feedback maintains the output voltage within an acceptable operating range to produce an efficacious output current pulse for stimulation without causing unproductive energy loss. In order to avoid premature depletion of battery energy, VUPC is compared with VCOMPL to determine the optimum clock rate to be used to convert VBAT to VUPC.

    摘要: Improved implantable monitoring systems suitable for long-term in vivo use to measure the concentration of one or more prescribed substances, such as glucose, are described herein. In particular, an implantable enzyme-based glucose monitoring system is described that includes at least one of the following: means for replenishing the enzyme solution as it is consumed by the enzymatic reaction; means for replenishing the electrolyte solution bathing the electrode assembly; and microprocessing means proximal the electrode assembly. In preferred embodiments, a microprocessor assembly is hermetically associated with the substrate to which the electrode assembly is affixed. Further, the monitoring systems employ one or more reservoir systems in fluid communication with enzyme and electrolyte chambers wherein the enzyme and electrolyte solutions are used. In a further embodiment, the monitoring systems use enzyme and electrolyte reservoir bulbs in fluid communication with the enzyme and electrolyte reservoirs, respectively, and positioned near the skin surface, thereby providing ready access to the enzyme and electrolyte solutions without the need for explantation of the device. Further provided herein is an enzyme solution comprising microspheres in association with the enzyme; whereby the enzyme is immobilized by the microspheres and the microspheres are in a fluid, flowable solution. Also provided herein is a method of extending the useful life of an implantable enzyme-based monitoring system, which method comprises providing means, within the system, to replenish the enzyme and/or electrolyte solution.

    摘要: This invention is for directly modulating a beam of photons onto the retinas of patients who have extreme vision impairment or blindness. Its purpose is to supply enough imaging energy to retinal prosthetics implanted in the eye which operate essentially by having light (external to the eye) activating photoreceptors, or photo-electrical material. The invention provides sufficient light amplification and does it logarithmically. While it has sufficient output light power, the output light level still remains at a safe level. Most preferred embodiments of this invention provide balanced biphasic stimulation with no net charge injection into the eye. Both optical and electronic magnification for the image, as for example, using an optical zoom lens, is incorporated. Otherwise, it would not be feasible to zoom in on items of particular interest or necessity. Without proper adjustment, improper threshold amplitudes would obtain, as well as uncomfortable maximum thresholds. Therefore, to adjust for these, a way of proper adjustment for the threshold amplitudes and maximum comfortable thresholds is provided. Furthermore, to the extent that individual stimulation sites in the retina give different color perceptions, upon stimulation, then colors of the viewed scene is correlated with specific stimulation sites to provide a certain amount of color vision.

    摘要: An implantable living tissue stimulator avoids the use of conventional coupling capacitors in its output stage, yet still prevents an average dc current flow from flowing through living tissue in electrical contact with the stimulator. The output stage generates and applies a biphasic stimulating current pulse to selected paired output terminals. The terminals, in turn, are electrically connected to respective electrodes which are positioned so as to contact the living tissue to be stimulated. In one embodiment, special circuitry is employed within the output stage to block dc current flow through the living tissue and to balance the electrical charge that is delivered to the living tissue. In another embodiment, the electrodes themselves are made from a material that allows them to function as a capacitor. In yet an additional embodiment, the coupling capacitors are integrated into the leads that connect the output terminals of the output stage with the electrodes.
