Publication number: 20160015265Abstract: Glaucoma is the second most common cause of blindness in the global world. It is a multifactorial disease with several risk factors, of which intraocular pressure (IOP) is the most important. IOP measurements are used for glaucoma diagnosis and patient monitoring. IOP has wide diurnal fluctuation, and is dependent on body posture, so the occasional measurements done by the eye care expert in clinic can be misleading. We provide an implantable sensor, based on microfluidic principles, which in one example has 1 mmHg limit of detection, high sensitivity and excellent reproducibility. This sensor has an optical interface, which enables IOP to be read with, for example, a cell phone camera. The design, fabrication, along with the option of self-monitoring are promising steps toward better patient care and treatment for this devastating disease.Type: ApplicationFiled: February 28, 2014Publication date: January 21, 2016Applicant: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Yosef Mandel, Ismail E Araci, Stephen R.

Publication number: 20160015266Abstract: Systems and methods of sensing intraocular pressure are described. An example miniaturized intraocular pressure (IOP) monitoring system is provided using a nanophotonics-based implantable IOP sensor with remote optical readout that can be adapted for both patient and research use. A handheld detector optically excites the pressure-sensitive nanophotonic structure of the IOP-sensing implant placed in the anterior chamber and detects the reflected light, whose optical signature changes as a function of IOP. Optical detection eliminates the need for large, complex LC structures and simplifies sensor design. The use of nanophotonic components improves the sensor's resolution and sensitivity, increases optical readout distance, and reduces its size by a factor of 10-30 over previous implants. Its small size and convenient optical readout allows frequent and accurate self-tracking of IOP by patients in home settings.Type: ApplicationFiled: September 28, 2015Publication date: January 21, 2016Inventors: Hyuck Choo, David Sretavan, Myung-Ki Kim

The multi-modal assessment system includes at least one channel of EEG brainwave data in combination with cognitive information that provide a two-dimensional data stream of (x(t), y(t)) of cognitive information; voice recordings; motion, position, and stability data; galvanic skin conductance; temperature of the subject; pulse-oximetry data, cerebral blood perfusion data, vaso-motor reactivity data, and the like. The collected data is processed to construct candidate features extracted from multiple biological sensor data streams and correlated with multi-modal signatures to identify data indicative of brain health, disease and injury.Type: ApplicationFiled: March 6, 2014Publication date: January 21, 2016Inventors: Adam J.

Publication number: 20160015291Abstract: This method of determining an intracochlea tissue impedance comprises using at least two stimulating electrodes to apply an electrical stimulus to intracochlea tissue. A voltage caused by the stimulus is measured between two measuring electrodes distinct from the stimulating electrodes. From the voltage a stimulus-response characteristic of tissue between the two measuring electrodes is determined This allows the tissue/electrode interface impedance and potential and the tissue impedance and potential to be uniquely determined. In turn, modiolus currents can be estimated in monopolar stimulation mode.Type: ApplicationFiled: September 30, 2015Publication date: January 21, 2016Inventors: Kostas Tsampazis, Paul Carter, Herbert Mauch

Publication number: 20160015292Abstract: A method and system for magnetically tracking a device of interest generating a plurality of pre-determined multi-frequency signals. The method and system transmits a plurality of magnetic fields from a transmitter circuit based on the corresponding pre-determined multi-frequency signals. The magnetic fields propagating through an area of examination encompassing the device of interest and a magnetic sensor coupled to the device of interest. The method and system generate a sensor signal at the magnetic sensor indicative of field strength of the magnetic fields transmitted by the transmitter circuit. Further, the method and system determine a position of the magnetic sensor relative to the transmitter circuit based on the multi-frequency signals and the sensor signal.Type: ApplicationFiled: July 15, 2014Publication date: January 21, 2016Inventors: Peter William Lorraine, Floribertus P.M.

Publication number: 20160015293Abstract: The invention relates to an interventional system comprising an interventional device (11) for being inserted into a living being (7) and comprising an optical shape sensing fiber, wherein the optical shape sensing fiber is used for determining respiratory motion by monitoring a movement of a part of the interventional device, which moves in accordance with the respiratory motion. Thus, respiratory motion can be determined, without necessarily requiring a physician to handle with further devices like a respiratory belt, i.e. the same interventional device can be used for performing an interventional procedure and for determining the respiratory motion. The interventional procedure can therefore be less cumbersome for a physician. Moreover, since the determination of the respiratory motion is based on optical shape sensing, which is a very accurate position determination technique, the respiratory motion can be determined very accurately.Type: ApplicationFiled: January 28, 2014Publication date: January 21, 2016Inventor: Sander Hans Denissen

Publication number: 20160015294Abstract: Navigation and tissue capture systems and methods for navigation to and/or capture of selected tissue using the innate electrical activity of the selected tissue and/or other tissue are described. In the context of left atrial appendage closure, the systems and methods can be used to navigate to the left atrial appendage and capture/control the appendage while a closure instrument (suture, clip, ring) is placed over the appendage and tightened down or a closure method (ablation, cryogenic procedures, stapling, etc.) is performed to close the left atrial appendage. The use of innate electrical activity for navigating devices may be used in connection with other tissues and/or areas of the body.Type: ApplicationFiled: September 28, 2015Publication date: January 21, 2016Inventors: PAUL A. FRIEDMAN, CHARLES J. BRUCE, SAMUEL J. ASIRVATHAM, TREVOR A. MCCAW, ELLIOT Y.K. HONG

Publication number: 20160015298Abstract: An apparatus for measuring the dimensions of human feet is comprised of a base and a cover, which fits over it to define the borders of two essentially rectangular wells into which the feet to be measured are placed. A pressure pad assembly comprising a matrix of sensors is placed at the bottom of base. The walls of the wells are defined by PCBS comprising arrays comprised of a multitude of emitter/detector pairs, which are used to make length and width measurements of said feet. MCUs on the pressure pad assembly and computation means comprise software algorithms that automatically make length, width, and pressure measurements and correct errors in the length and width measurements caused by misalignment of the feet in the wells.
