    摘要： An implantable medical device is made from an electronic subassembly hermetically sealed in a ceramic case filled with a potting material. Use of the potting material enhances the capacity of the device to withstand mechanical shock without failure. The device includes a hollow ceramic or other case having an open end to which a metal ring is hermetically bonded. The inside surface of the ceramic case is treated (cleansed and activated) to assure the potting material adheres to it. The potting material, while in a non-cured fluid or quasi-fluid state, is inserted inside of the ceramic case. The electronic circuitry is next inserted into the open end of the ceramic case while the potting material is still in a non-cured, soft or fluid state. The electronic circuitry displaces some of the potting material and the potting material fills the voids between the electronic circuitry and the ceramic case. The potting material is then slowly cured, and once cured, supports the walls of the ceramic case and protects the electronic circuitry embedded therein. A header (to which the electronic circuitry is attached) is hermetically bonded to the metal band on the open end of the ceramic case, thereby hermetically sealing the implantable device.

    摘要： The present invention provides a fully implantable cochlear implant system (FICIS) that allows various configurations of different modules to be combined so as to meet the needs of a particular patient, including very young patients. At least three main modules are used in the FICIS, including (1) a small implantable cochlear stimulator (ICS) module, with permanently attached cochlear electrode array; (2) an implantable speech processor (ISP) module, with integrated microphone and rechargeable battery; and (3) an external module. In one embodiment, the external module may comprise an external speech processor (ESP) module. In another embodiment, the external module may comprise an external battery charger (EBC) module. The ICS and ISP modules are configured to facilitate long time reliable use of the ICS module, e.g., for the lifetime of the patient, and low-risk, relatively easy replacement of the ISP module.

    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.

    摘要： A glucose monitoring system continuously measures the glucose concentration in a patient's blood, provides an indication of the rate of change of such concentration, and determines whether the measured concentration and rate of change are within certain preset limits. If not, an audible and/or visual alarm signal is generated. The glucose monitoring system includes a glucose sensor adapted to be inserted into the venous system of the patient, where it responds to blood glucose and produces sensor signals related to the glucose concentration. The sensor signals are delivered through a suitable interconnect cable to a glucose monitor. In one embodiment, the interconnect cable includes a contactless connector that electrically isolates the glucose sensor from the monitor, and reduces the number of conductors required to interface with a plurality of sensors. The glucose monitor interprets the sensor signals by applying a previously determined calibration to quantitatively determine the blood glucose value. The blood glucose value thus determined is then processed in order to determine the rate of change, is stored (to create a history or record), and may also be displayed in large, easy-to-read numerals. Rate of change information (trend) may also be numerically or graphically displayed.

    摘要： A shield for the conductors extending from an implantable device, provides a cover for the conductors and protects them against being dislodged or moved, by scratching, physical activity, skin pressure or other circumstance. The cover is resilient and flexible and is made of a fabric laminated between layers of an elastomer, such as silicone rubber. The cover is fixedly attached at one end with respect to the implantable device. The cover is suturable to hold the implantable device, cover and conductors in place, thereby providing stabilization. The shield is disposed over the location where the conductors extend from the implanted device and provides strain relief for the conductors and protects them from breakage at that very fragile location. The shield partially or totally encircles the conductors for a short distance.
