Publication number: 20160041323Abstract: This disclosure provides systems, methods and apparatus for illumination, such as for illuminating displays, including reflective displays. An illumination device may include a light-extracting, diffusive holographic medium. The holographic medium may be a holographic film and may be disposed on the surface of a light guide, and includes a hologram that both extracts light out of the light guide and diffuses this extracted light for propagation towards the display elements of the display. The hologram can extract light by redirecting light, which is propagating within the light guide, so that the light propagates out of the light. The diffusion occurs upon the light being redirected, as the hologram redirects the light towards the light guide in a controlled range of angles.Type: ApplicationFiled: August 8, 2014Publication date: February 11, 2016Inventors: Jian Ma, Kebin Li, Chung-Po Huang, Tallis Young Chang, John Hyunchul Hong, Mark Phung, Zheng-wu Li

Publication number: 20100234935Abstract: A stent assembly comprises an expandable stent having a first stent backbone which extends from the proximal end of the stent to the distal end of the stent. The stent comprises a first stent back bone oriented in a direction which is substantially parallel to a longitudinal axis of the stent, and a plurality of interconnected first stent members and second stent members. Each of the first stent members is oriented in a substantially longitudinal direction in the unexpanded state and the expanded state. Each of the second stent members is oriented in a substantially longitudinal direction in the unexpanded state and oriented in a substantially circumferential direction in the expanded state. The first stent backbone has a greater column strength than that of the plurality of interconnected stent members.Type: ApplicationFiled: June 2, 2010Publication date: September 16, 2010Applicant: Boston Scientific Scimed, Inc.Inventors: Mehran Bashiri, Mark Phung, Kamal Ramzipoor, Ajitkumar B. Nair

Publication number: 20070239201Abstract: An embolus extractor including elongated shaft having a proximal end and a distal end. The embolus extractor may include first and second struts coupled to the distal end of the shaft. The struts may define a proximally disposed mouth.Type: ApplicationFiled: June 18, 2007Publication date: October 11, 2007Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Mark Phung, Pete Pham, Mehran Bashiri, Ajitkumar Nair, Beth Camins

Publication number: 20050267491Abstract: Devices and methods for removing a foreign object from a body lumen are disclosed. An embolectomy device can include a filter basket having a plurality of filter struts forming a cage-like structure that can be expanded to circumferentially surround the incoming foreign object. A support frame including a proximal hoop and one or more rail members may be employed to support the filter basket. The support frame and filter basket can be coupled to a pusher wire that can be used to manipulate the device within the body. In certain embodiments, the filter struts may vary in thickness to impart a desired flexibility characteristic to the device. Methods of manufacturing such devices are also disclosed.Type: ApplicationFiled: July 19, 2005Publication date: December 1, 2005Inventors: James Kellett, Valerie Sontrop, Greg Welsh, Dushyant Shah, Kamal Ramzipoor, Mehran Bashiri, Ajitkumar Nair, Andrew Huffmaster, Thomas Chien, Mark Phung, Mediko Issakhani
