Publication number: 20140207162Abstract: Methods and devices for blocking orifices and occluding cavities within a patient are provided. The device in one variation comprises first and second tubular members attached to a collapsible sealing element. The device can be placed through an orifice and the collapsible sealing element can be collapsed to seal the orifice. An embolic may be introduced distal to the sealing element to occlude a cavity. The device may incorporate a locking mechanism which can be engaged to lock the sealing element into the collapsed position. The device may incorporate a valve to prevent flow through the tubular members, for example to prevent egress of the embolic from a cavity. The device can be detached to provide a permanent seal of the orifice, and can retain the embolic within the cavity. The device may be used in conjunction with a stent or other retention device to assist the sealing element in maintaining the seal.Type: ApplicationFiled: April 7, 2014Publication date: July 24, 2014Inventors: Tri Tran, Kim Nguyen, Hanh Ho, My Doan, Richard Murphy, Michael P.

Patent number: 7911014Abstract: An antenna with air-filled trench is integrated with a radio frequency (RF) circuit. The trench locates directly under the metal lines that made up the antenna and is formed by etching from the back side of the semiconductor substrate until all the substrate material in the trench is removed. The air-filled trench greatly reduces the losses due to the semiconductor substrate; therefore the performance of the antenna improves greatly. When the antenna is a large planar spiral inductor, the air-filled trench means the semiconductor substrate inside the spiral inductor is untouched; hence integrated circuit can be built inside the antenna and on that substrate. Therefore the RF integrated circuit has a smaller size. Air-filled trench can also be used to reduce the semiconductor substrate noise coupling between digital circuit block and analog/RF circuit block. This air-filled trench and the air-filled trench under the antenna are formed at the same time.Type: GrantFiled: September 29, 2008Date of Patent: March 22, 2011Inventor: My The Doan

Publication number: 20090087137Abstract: An air filled trench is formed underneath the waveguide to reduce propagation loss, which in turn allowing the waveguide to be in the close proximity of on-chip devices, such as a photodetector. The air filled trench is formed from the back side of the substrate; hence it would not disturb the integration and the formation of components on the front side of the substrate. In another embodiment, for silicon-on-insulator (SOI) based device, with an air filled trench and a metal electrode, a back gate is formed. In yet another embodiment, air filled trench also reduces the substrate loss of RF passive components and passive antenna operating in Giga Hertz range. Air filled trenches can be used for both photonic and electronic circuits in a planar lightwave circuit. Finally, another embodiment is for the trench to effectively guide gases and fluids to pass through the detection area.Type: ApplicationFiled: October 2, 2007Publication date: April 2, 2009Inventor: My The Doan

Patent number: 7349614Abstract: A new method to form a VLSI-photonic heterogeneous system device is achieved. The method comprises providing an optical substrate comprising at least one passive optical component formed therein. An electronic substrate is provided comprising at least one active electronic component formed therein.

Patent number: 7248773Abstract: Formation, through etching, of structures whose minimum width is less than can be achieved by optical means alone has been achieved by inserting a layer of sandwiching material between the photoresist (or hard mask if used) and the structure. By adjustment of the relative etch rates of this layer and the structure, a uniform lateral width reduction and surface smoothing of the structure is achieved.Type: GrantFiled: December 4, 2006Date of Patent: July 24, 2007Assignee: Agency For Science, Technology, and ResearchInventors: Chang Kuo Chang, Chi Fo Tsang, My The Doan, Ramana Murthy Badam, Vladimir Bliznetsov
