20090002067 | Method and System for Signal Coupling and Direct Current Blocking - A method and class of circuit configurations for coupling low-frequency signals from one stage of an electronic apparatus to another stage, from the outside world to such a stage, or from such a stage to the outside world, through the use of a plurality of symmetrical double-layer capacitors combined with other electronic components are disclosed. The capacitors are used for signal transmission while blocking direct current, rather than for energy storage. Use of double-layer capacitors in place of more conventional capacitors permits the transmission of a much wider range of signals with far less distortion. The technology is particularly well-adapted to use in medical devices, including bioelectronic stimulators, where redundant devices are required for safety in case of single component failure while unacceptable levels of distortion may occur when conventional components are used. | 01-01-2009 |
20090132010 | SYSTEM AND METHOD FOR GENERATING COMPLEX BIOELECTRIC STIMULATION SIGNALS WHILE CONSERVING POWER - A system and method for generating an electrical signal for use in biomedical applications may have power efficient features, support battery powered operation and, support a reduced risk of shock hazard. The system may include a controller for generating one or more control signals operable to control pulse generating and waveform processing circuits. The control signals may include at least two states alternating in a chosen pattern as a function of time. During at least one of the control signal states, an oscillator for generating a pulsed signal may be operable. During at least another of the control signal states, the oscillator can be disabled and completely shut off in order to conserve considerable power. The generated pulses may be processed to provide desired intensity and frequency components. The processed signals may be applied to biological material. | 05-21-2009 |
20110217775 | METHODS FOR MODULATING OSTEOCHONDRAL DEVELOPMENT USING BIOELECTRICAL STIMULATION - Compositions and methods are provided for modulating the growth, development and repair of bone, cartilage or other connective tissue. Devices and stimulus waveforms are provided to differentially modulate the behavior of osteoblasts, chondrocytes and other connective tissue cells to promote proliferation, differentiation, matrix formation or mineralization for in vitro or in vivo applications. Continuous-mode and pulse-burst-mode stimulation of cells with charge-balanced signals may be used. Bone, cartilage and other connective tissue growth is stimulated in part by nitric oxide release through electrical stimulation and may be modulated through co-administration of NO donors and NO synthase inhibitors. Bone, cartilage and other connective tissue growth is stimulated in part by release of BMP-2 and BMP-7 in response to electrical stimulation to promote differentiation of cells. The methods and devices described are useful in promoting repair of bone fractures, cartilage and connective tissue repair as well as for engineering tissue for transplantation. | 09-08-2011 |
