| 20090081552 | ELECTROCHEMICAL CELL WITH TIGHTLY HELD ELECTRODE ASSEMBLY - An electrochemical cell comprising a conductive casing housing an electrode assembly provided with a stack holder surrounding the electrode assembly is described. The stack holder is of an elastic material that serves to maintain the anode and cathode in a face-to-face alignment throughout discharge. This is particularly important in later stages of cell life. As the cell discharges, anode active material is physically moved from the anode to intercalate with the cathode active material. As this mass transfer occurs, the cathode becomes physically larger and the anode smaller. This can lead to misalignment. However, the stack holder prevents such misalignment by maintaining a constrictive force on the electrode assembly throughout discharge. | 03-26-2009 |
| 20100125312 | SATELLITE THERAPY DELIVERY SYSTEM FOR BRAIN NEUROMODULATION - Deep brain electrodes are remotely sensed and activated by means of a remote active implantable medical device (AIMD). In a preferred form, a pulse generator is implanted in the pectoral region and includes a hermetic seal through which protrudes a conductive leadwire which provides an external antenna for transmission and reception of radio frequency (RF) pulses. One or more deep brain electrode modules are constructed and placed which can transmit and receive RF energy from the pulse generator. An RF telemetry link is established between the implanted pulse generator and the deep brain electrode assemblies. The satellite modules are configured for generating pacing pulses for a variety of disease conditions, including epileptic seizures, Turrets Syndrome, Parkinson's Tremor, and a variety of other neurological or brain disorders. | 05-20-2010 |
