The device can include one or more light emitters, one or more light sensors, and a material whose optical properties can be changed in one or more locations to adjust the optical path and the effective separation distances between the one or more light emitters and one or more light sensors or the size, location, or shape of the one or more dynamically reconfigurable apertures. In some examples, the material can be a liquid crystal material, MEMS shutter layer, or light guide, which can form the one or more dynamically reconfigurable apertures. In some examples, the light emitters or light sensors or both can be an array of individually addressable optical components.Type: ApplicationFiled: September 6, 2018Publication date: January 17, 2019Inventor: Chin San HAN

Publication number: 20190015002Abstract: An intravascular catheter for nerve activity ablation and/or sensing includes one or more needles advanced through supported guide tubes (needle guiding elements) which expand to contact the interior surface of the wall of the renal artery or other vessel of a human body allowing the needles to be advanced though the vessel wall into the extra-luminal tissue including the media, adventitia and periadvential space. The catheter also includes structures which provide radial and lateral support to the guide tubes so that the guide tubes open uniformly and maintain their position against the interior surface of the vessel wall as the sharpened needles are advanced to penetrate into the vessel wall. Electrodes near the distal ends of the needles allow sensing of nerve activity before and after attempted renal denervation. In a combination embodiment ablative energy or fluid is delivered from the needles in or near the adventitia to ablate nerves outside of the media while sparing nerves within the media.Type: ApplicationFiled: July 13, 2018Publication date: January 17, 2019Inventors: David R.

Publication number: 20190015003Abstract: Embodiments include methods, systems, and apparatuses for generating an enhanced electrocardiograph (ECG) that includes indicators of values of different types of supplemental information embedded into a trace of measured electrical potentials. More specifically, embodiments may include collecting first data samples of electrical potentials produced by a heart at a sequence of sampling times, and processing the data to calculate supplemental information over a number of sampling times. Based on the first data samples and the supplemental information, a trace of the electrical potentials collected at the sampling times is presented. The trace may have one or more embedded indicators of the supplemental information that vary responsively to the first data samples collected at each of the sampling times.Type: ApplicationFiled: July 11, 2017Publication date: January 17, 2019Applicant: Biosense Webster (Israel) Ltd.Inventors: Shmuel Auerbach, Gil Zigelman, Maxim Galkin

Publication number: 20190015005Abstract: A device and method is described for electronic human prosthetics, and specifically a body-machine interface (BMI) device where the input, output and on-board computing are combined into a single unit to form a compact ECG, respiratory sensing, temperature-sensing-prosthetics device. The devices (BMIs) can also communicate with other body-machine interface devices (BMI) and/or with external controllers wirelessly. The compact device has ultrasonic battery charging system. One or more BMI can be wirelessly connected so that a closed loop of BMIs, or a BMI and an external controller, can wirelessly send trigger pulses to the stimulator over the heart, glossopharyngeal nerve(s) or diaphragm.Type: ApplicationFiled: July 14, 2018Publication date: January 17, 2019Applicants: San Diego State University Research Foundation, Electronic and Telecommunication Research InstituteInventors: Kee S.

Publication number: 20190015006Abstract: An ECG system measures and annotates the P-point of an ECG waveform from harmonic waveforms. Electrical impulses are received from a beating heart. The electrical impulses are converted to an ECG waveform. The ECG waveform is converted to a frequency domain waveform, which, in turn, is separated into two or more different frequency domain waveforms, which, in turn, are converted into a plurality of time domain cardiac electrophysiological subwaveforms and discontinuity points between these subwaveforms. The plurality of subwaveforms and discontinuity points are compared to a database of subwaveforms and discontinuity points for normal and abnormal patients. A discontinuity point is identified as the P-point of the ECG waveform from the comparison. Similar measurements are made for the P?-point, I-point, J-point, and T?-point. Distances from these points to the equipotential line are calculated and used to detect blockages leading to myocardial infarction.Type: ApplicationFiled: August 27, 2018Publication date: January 17, 2019Inventors: Guangren Chen, Rong Yang
