| 20100308813 | HIGH SENSITIVITY SOLID STATE MAGNETOMETER - A magnetometer for sensing a magnetic field may include a solid state electronic spin system, and a detector. The solid state electronic spin system may contain one or more electronic spins that are disposed within a solid state lattice, for example NV centers in diamond. The electronic spins may be configured to receive optical excitation radiation and to align with the magnetic field in response thereto. The electronic spins may be further induced to precess about the magnetic field to be sensed, in response to an external control such as an RF field, the frequency of the spin precession being linearly related to the magnetic field by the Zeeman shift of the electronic spin energy levels. The detector may be configured to detect output optical radiation from the electronic spin, so as to determine the Zeeman shift and thus the magnetic field. | 12-09-2010 |
| 20100315079 | ELECTRONIC SPIN BASED ENHANCEMENT OF MAGNETOMETER SENSITIVITY - A method is disclosed for increasing the sensitivity of a solid state electronic spin based magnetometer that makes use of individual electronic spins or ensembles of electronic spins in a solid-state lattice, for example NV centers in a diamond lattice. The electronic spins may be configured to undergo a Zeeman shift in energy level when photons of light are applied to the electronic spins followed by pulses of an RF field that is substantially transverse to the magnetic field being detected. The method may include coherently controlling the electronic spins by applying to the electronic spins a sequence of RF pulses that dynamically decouple the electronic spins from mutual spin-spin interactions and from interactions with the lattice. The sequence of RF pulses may be a Hahn spin-echo sequence, a Can Purcell Meiboom Gill sequence, or a MREV8 pulse sequence, by way of example. | 12-16-2010 |

| 20100258784 | Method Of Efficient Coupling Of Light From Single-Photon Emitter To Guided Radiation Localized To Sub-Wavelength Dimensions On Conducting Nanowires - A cavity free, broadband approach for engineering photon emitter interactions via sub-wavelength confinement of optical fields near metallic nanostructures. When a single CdSe quantum dot (QD) is optically excited in close proximity to a silver nanowire (NW), emission from the QD couples directly to guided surface plasmons in the NW, causing the wire's ends to light up. Nonclassical photon correlations between the emission from the QD and the ends of the NW demonstrate that the latter stems from the generation of single, quantized plasmons. Results from a large number of devices show that the efficient coupling is accompanied by more than 2.5-fold enhancement of the QD spontaneous emission, in a good agreement with theoretical predictions. | 10-14-2010 |

| 20080221597 | Methods and devices for intragastrointestinal fixation - A device for fixating a gastrointestinal device may include a band of material that may be wrapped around the gastrointestinal tract, for example, by wrapping the band around the outside of the stomach or wrapping the band in such a way that it is integrated into and/or with the stomach tissue. In this illustrative embodiment, the band restricts the stomach such that the stomach lumen is constricted and/or the stomach is restricted from expanding beyond what the band will allow. | 09-11-2008 |
| 20080221702 | Methods and devices for intragastrointestinal prostheses - An intragastric and/or intragastrointestinal device may include a prosthesis, which may reside within the gastrointestinal tract lumen. The device may include a restrictive element that constricts or restricts the gastrointestinal tract lumen, limiting the amount of food and/or fluid an individual consumes. | 09-11-2008 |
| 20100174140 | INTEGRATED ENDOSCOPE AND ACCESSORY TREATMENT DEVICE - An integrated endoscope and accessory treatment device is provided. The device employs a medical treatment device at its distal end that is combined with the endoscope as a complete system. The treatment device is controlled by integrated elements at the proximal end of the endoscope. The treatment devices may include tissue apposition devices, tissue cutting devices, forceps and others. | 07-08-2010 |

| 20080215069 | Endoscopic tissue apposition device with multiple suction ports - The present invention relates to an improved endoscopic tissue apposition device having multiple suction ports. The invention permits multiple folds of tissue to be captured in the suction ports with a single positioning of the device and attached together by a tissue securement mechanism such as a suture, staple or other form of tissue bonding. The improvement reduces the number of intubations required during an endoscopic procedure to suture tissue or join areas of tissue together. The suction ports may be arranged in a variety of configurations on the apposition device to best suit the desired resulting tissue orientation. The inventive tissue apposition device may also incorporate tissue abrasion means to activate the healing process on surfaces of tissue areas that are to be joined by operation of the device to promote a more secure attachment by permanent tissue bonding. | 09-04-2008 |
