| 20090020916 | Composite ceramic having nano-scale grain dimensions and method for manufacturing same - A composite ceramic including a first phase of ceramic material and a second phase of ceramic material, the first and second phases forming three dimensional interconnected networks of each phase and having a nano-scaled grain size. The composite ceramic is produced in a method which utilizes rapid solidification at cooling rates of at least ˜10 | 01-22-2009 |
| 20090042716 | High Temperature Reactor for the Poduction of Nanophase WC/CO Powder - A method for producing a nanostructured cermet material, including the steps of preparing an aqueous solution mixture of precursor compounds of the cermet material, introducing the solution mixture into a heated tubular reactor in the form of a fine-particle aerosol, and processing the solution mixture in the heated tubular reactor to form the nanostructured cermet material. The present invention is further directed to a processing apparatus configured for implementing the present method. | 02-12-2009 |
| 20090104495 | Electrode assembly for a solid oxide fuel cell and method for making the same - An electrode assembly for a solid oxide fuel cell, the electrode assembly including a porous ceramic oxide matrix and an array of fluid conduits. The porous ceramic oxide matrix includes a labyrinth of reinforcing walls interconnected to one another. Each of the fluid conduits is formed from the porous ceramic oxide matrix and has an external surface with a plurality of struts projecting outwardly therefrom and an internal surface defining a first passage for flowing a first fluid therethrough. The struts are configured to connect the fluid conduits to one another and the external surfaces and the struts define a second passage around the fluid conduits for flowing a second fluid therethrough. | 04-23-2009 |

| 20090198250 | Medical Device - A stone retrieval suction device facilitates the retention and then relocation and/or removal of objects disposed in a patient's urinary system. The device includes an elongated member for placement in a channel of a flexible ureteroscope. The elongated member defines a suction passageway which extends longitudinally therethrough. The elongated member is flexible enough to bend with the flexible ureteroscope, and it is strong enough to prevent collapse of the suction passageway when suction is provided through the suction passageway by a vacuum source. The elongated member includes a distal portion for contacting and retaining an object when the suction is provided. | 08-06-2009 |
| 20100204711 | MEDICAL RETRIEVAL DEVICE - A medical retrieval device has a multi-prong retrieval assembly. The multi-prong retrieval assembly has a first position, in which the retrieval assembly extends from the distal end of the sheath to form an open ended grasping device, and a second position, in which the retrieval assembly extends from the distal end of the sheath to form a substantially close ended basket-type retrieval device. When the retrieval assembly is used as a basket-type retrieval device, the distal ends of the prongs of the retrieval assembly that form the basket are not connected to each other. Thus, captured objects may be released by the operator, or by applying sufficient force to separate one or more of the prongs. | 08-12-2010 |
| 20110028987 | Medical retrieval device with frangible basket - The invention relates to a medical retrieval device with a basket that has at least one leg that is frangible (i.e., easily breakable) and/or able to dissociate from at least one other leg upon the application of a predetermined force to the basket. The invention allows an operator to release captured material (e.g., a stone) from the basket when the device is still inserted in the body. In an embodiment, the basket legs associate by a magnetic interaction that can be overcome by applying a predetermined force to the basket. In another embodiment, at least a portion of at least one basket leg is made from, or coated with, a substance that is adhesive or that joins at least two legs together when the substance is solid but which melts, dissolves or weakens upon the application of an electrical, thermal or chemical change. In yet another embodiment, the invention provides a basket with at least two legs that are joined together by a joining member that can break, or from which one or more legs can dissociate, upon the application of a predetermined force. In yet another embodiment, the invention provides a basket with at least two legs that are joined together by a joining member by means of at least one shear pin that can break upon the application of a predetermined force. | 02-03-2011 |

| 20110206888 | Composite Ceramic Structure and Method of Making the Same - A composite ceramic structure such as, for example, a PZT ceramic structure including, in one embodiment, a plurality of ceramic elements encapsulated in a layer of epoxy material. Each of the ceramic elements includes opposed first and second ends terminating in opposed respective top and bottom surfaces of the composite ceramic structure. A layer of conductive material on the top surface of the composite ceramic structure covers only the respective first ends of the ceramic elements to isolate the same from each other. A layer of conductive material covers the entire bottom surface of the composite ceramic structure to ground the opposed second ends of the plurality of ceramic elements to each other. A method of making the composite ceramic structure described above is also disclosed. | 08-25-2011 |

| 20090058230 | Bond pad for use with piezoelectric ceramic substrates - A piezoelectric assembly includes a piezoelectric substrate that has a top surface, a bottom surface, and at least one side surface. A top electrode is defined on the top surface and a first aperture is defined in the top electrode. A bottom electrode is disposed on the bottom surface. The electrodes are formed from a thin film metal. A first thick film bond pad is disposed in the first aperture and is in contact with the piezoelectric substrate. The first thick film bond pad is in electrical contact with the top electrode. In further embodiments, a second thick film bond pad is disposed on either the top surface or in a second aperture defined in the bottom electrode. | 03-05-2009 |
