Publication number: 20110282161Abstract: A first light source producing a first light beam with a first intensity and a second light source producing a second light beam with a second intensity. A light filter device receives the first light beam and transmits a filtered portion of the first light beam. A first angling device reflects the filtered portion of the first light beam in a first angled direction and a second angling device reflects the second light beam in a second angled direction. A mirror receives and in turn reflects the filtered portion of the first light beam reflected by the first angling device and the second light beam reflected by the second angling device to form a converged light beam with a third intensity.Type: ApplicationFiled: July 25, 2011Publication date: November 17, 2011Applicant: DOHENY EYE INSTITUTEInventors: Prashant Bhadri, James Lescoulie, Sophia Fang, Matthew McCormick, Ralph Kems, Mark Humayun, Aaron Barnes

Publication number: 20110276340Abstract: A personal surgical center embodied as a general purpose computer (e.g. laptop) with wireless technology for monitoring the operation of an independent surgical center and/or handheld instruments. The computer tracks procedures in the operating room and instruments used during those procedures, and accounts for billing, supply management, and payment options. The monitoring of the instruments used during the surgery is conducted by the personal surgical center while actual control of the settings of those instruments is via the independent surgical center or via controls included in the instruments themselves. The monitored information is stored in a log file which is then transmitted to a hospital server for generating reports, inventory control, billing, and the like. Other information generated during the procedure (e.g. doctor notes) is also stored in the log file.Type: ApplicationFiled: April 11, 2011Publication date: November 10, 2011Applicant: DOHENY EYE INSTITUTEInventors: Charles DeBoer, Matthew McCormick, Ralph Kerns, Prashant Bhadri, Lawrence Chong, Mark Humayun

Patent number: 8027814Abstract: The present invention provides methods for assessing a condition in an individual by analyzing a cerebrospinal fluid sample from the individual, for example, by spectroscopy. Further, the invention provides methods for determining an amount of blood in the cerebrospinal fluid sample; methods for determining concentrations of analytes in the cerebrospinal fluid sample; methods for determining a length of time the blood has been in the cerebrospinal fluid sample; and methods for rapidly obtaining a differential diagnosis between conditions indicated by blood in the cerebral spinal fluid. Moreover, the present invention provides instruments capable of rapidly assessing a condition in and individual by point-of-care analysis of a cerebral fluid sample from an individual.Type: GrantFiled: August 1, 2005Date of Patent: September 27, 2011Assignee: University of CincinnatiInventors: Fred R. Beyette, Jr., Joseph F. Clark, Chad J. Morgan, James J. Caffery, Jr., Prashant Bhadri, Gail Pyne-Geithman, Anindya Majumder

Publication number: 20110190690Abstract: A biological tissue cutting and fluid aspiration system provides a plurality of surgical instruments operable independent of an external control console. In some embodiments, each surgical instrument may include all sensors and controls directly applicable to the surgical instrument, and may be used independently. In some embodiments, instruments communicate status information to each other, and adjust operating parameters based on the communications.Type: ApplicationFiled: April 11, 2011Publication date: August 4, 2011Applicant: DOHENY EYE INSTITUTEInventors: Mark Humayun, Charles DeBoer, Ralph Kerns, Matthew McCormick, Prashant Bhadri, Lawrence Chong

Publication number: 20090016075Abstract: The present disclosure is directed to illumination techniques that include the use of one or more sets of Light Emitting Diodes or LEDs as light sources in a console/module system. The LED light sources can be utilized to produce a light beams with a specified/combination of intensity and spectrum. Of course, embodiments according to the present disclosure are not limited to one intensity/spectrum but multiple combinations of intensity and spectrum can be implemented. Such systems/methods can be implemented with various optical elements including filter, lenses, mirrors, and/or optical fibers. The system is controlled by voice activation, touch screen, footswitch or wireless communication. The LEDs might also be pulsed as a driving system. The optical fiber cable is tethered to the control.Type: ApplicationFiled: July 14, 2008Publication date: January 15, 2009Applicant: Doheny Eye InstituteInventors: Prashant Bhadri, Ralph Kerns, Mark S.

Publication number: 20070003209Abstract: A method is provided for fabricating microelectrodes and microelectrode arrays by etching in an acid solution. Glass wafers are diced into a desired shape to form narrow probes, which are immersed in the acid solution. An organic layer on top of the acid solution forms a meniscus at the point of contact with the probes, and the taper angle on the etched probes will depend on this meniscus angle. After etching, the tapered probes are coated with a conductive layer, followed by an insulating layer over most of their length so as to leave a small conductive area exposed at the tip. The glass wafer containing the probes is then mounted on a printed circuit board carrier.Type: ApplicationFiled: October 24, 2005Publication date: January 4, 2007Inventors: Ian Papautsky, Jin Lee, Paul Bishop, Fred Beyette, Prashant Bhadri, Am Jang, William Timmons
