20110230784 | USE OF IMPEDANCE TECHNIQUES IN BREAST-MASS DETECTION - A device is described for measuring electrical characteristics of biological tissues with plurality of electrodes and a processor controlling the stimulation and measurement in order to detect the presence of abnormal tissue masses in the breast and determine probability of tumors containing malignant cancer cells being present in a breast. The device has the capability of providing the location of the abnormality, at least to the quadrant. The method for measuring electrical characteristics includes placing electrodes and applying a voltage waveform in conjunction with a current detector. A mathematical analysis method is then applied to the collected data, which computes spectrum of frequencies and correlates magnitudes and phases with given algebraic conditions to determine mass presence and type. | 09-22-2011 |

20110105826 | TRANSCRANIAL MAGNETIC STIMULATION BY ENHANCED MAGNETIC FIELD PERTURBATIONS - Described herein are devices, systems and methods to enhance the magnetic perturbation of a neuronal (e.g., brain) target during Transcranial Magnetic Stimulation (TMS), thereby enhancing the induced current in the target. In general, these devices, systems and methods enhance the magnetic perturbation (dB/dt) of the target by mechanically moving a TMS electromagnet (e.g. coil) at a frequency of greater than 1 kHz. | 05-05-2011 |
20110112394 | NEUROMODULATION OF DEEP-BRAIN TARGETS USING FOCUSED ULTRASOUND - Disclosed are methods and systems for non-invasive deep brain or superficial neuromodulation for up-regulation or down-regulation using ultrasound impacting one or multiple points in a neural circuit to produce Long-Term Potentiation (LTP) or Long-Term Depression (LTD) to treat indications such as neurologic and psychiatric conditions. Ultrasound transducers are positioned by spinning them around the head on a track, as well as individually rotated or not, with control of direction of the energy emission, intensity, frequency, and phase/intensity relationships to targeting and accomplishing up-regulation and/or down-regulation. Alternatively the ultrasound transducers may be at fixed locations on the track. Use of ancillary monitoring or imaging to provide is optional. | 05-12-2011 |

20140194726 | Ultrasound Neuromodulation for Cognitive Enhancement - Disclosed are methods and systems for non-invasive neuromodulation using ultrasound for cognitive enhancement. Cognitive enhancement can be used for mitigation of abnormal conditions such as Alzheimer's Disease, Parkinson's Disease or stroke, or for enhancement in a normal individual. The neuromodulation can produce acute or long-term effects. The latter occur through Long-Term Depression (LTD) and Long-Term Potentiation (LTP) via training. Included is control of direction of the energy emission, intensity, frequency, pulse duration, pulse pattern, mechanical perturbation, and phase/intensity relationships to targeting and accomplishing up regulation and/or down regulation. | 07-10-2014 |

20090173682 | System and Method for Conducting Hemodialysis and Hemofiltration - An extracorporeal blood processing system comprises a plastic molded compact manifold that supports a plurality of molded blood and dialysate fluidic pathways along with a plurality of relevant sensors, valves and pumps. A disposable dialyzer is connected to the molded manifold to complete the blood circuit of the system. The compact manifold is also disposable in one embodiment and can be detachably installed in the dialysis machine. Two-way valves in the manifold are used to direct the dialysate flow to the dialyzer in hemodialysis mode of operation and to bypass the dialyzer to direct the flow of infusion grade dialysate directly to the patient in hemofiltration mode of operation. | 07-09-2009 |
