In some aspects, performing the heart rate variability analysis includes measuring R-R intervals between successive R-waves for the ECG data measured during a stimulation period of VNS therapy and a baseline period of the VNS therapy, wherein the stimulation period comprises at least a portion of the ON period and the baseline period comprises at least a portion of the OFF period immediately preceding the ON period, and generating a plot of each R-R interval against an immediately successive R-R interval for each of the stimulation period and the baseline period configured to be displayed on a display.

Abstract: An iridocorneal angle of the eye can be opened with a plurality of treatment locations at least about 2 mm radially outward from a limbus of the eye. The opening on the angle can be beneficial for treating both narrow angle glaucoma and open angle glaucoma. The plurality of treatment locations located away from the limbus can decrease invasiveness and complexity of the procedure. The plurality of treatment locations at least about 2 mm away from the limbus can provide tensioning to zonules coupled to the lens of the eye to flatten the lens of the eye, which can allow the iris to move posteriorly so as to open the iridocorneal angle. The plurality of treatment locations may comprise scleral locations, in which shrinkage of scleral tissue at the plurality of treatment locations provides tensioning to the zonules.

Abstract: A device and method for the pre-display of a spot pattern to be applied for a laser treatment of the eye.

Abstract: A method of determining blood pressure measurements includes inflating a cuff, receiving an indication of pressure inside the cuff during inflation, determining a blood pressure based at least in part on the received indication, assigning a confidence level to the blood pressure, and determining whether the confidence level satisfies a threshold confidence level. Based at least on a determination that the confidence level satisfies a threshold confidence level, the method can include causing a display to display the blood pressure. Based at least on a determination that the confidence level does not satisfy a threshold confidence level, the method can include deflating the cuff, receiving an indication of pressure inside the cuff during deflation, determining another blood pressure, and causing a display to display a blood pressure.

Abstract: A method of treating a patient having an eye condition includes determining, during a pre-operative analysis of the patient, that the patient has a risk of developing glaucoma. The method further includes treating the patient with an excimer laser to prophylactically treat glaucoma based on the pre-operative analysis determination that the patient has the risk of developing glaucoma.

Abstract: Methods are disclosed for reduction of muscle fatigue, enhancement of wound healing and tissue repair and/or reduction of pain. The methods comprise irradiating a muscle or an injured tissue of a subject, as applicable, with pulsed blue and/or red light having an average irradiance that ranges from 0.1 mW/cm2 to 20 mW/cm2 at a radiant exposure that ranges from 0.5 J/cm2 to 60 J/cm2. The pulsed blue and/or red light is preferably applied with a flexible light source that includes a flexible light emitter positioned between a flexible anode and a flexible cathode. The flexible light emitter may comprise a printed LED film or OLEDs that emit blue and/or red light, or a printed LED film or OLEDs that emit blue light in combination with a quantum dot film that converts a portion of the blue light emission into red light.

Abstract: A human body support has a plurality of electrodes arranged in an array and spaced longitudinally with respect to the human body. The array extends from an inferior position to a more superior position along the body. A sensor measures a parameter of the human body that is capable of indicating the presence of drowsiness. A controller has an input connected to the sensor for receiving a signal representing the sensed parameter and has outputs connected to each of the electrodes. The controller detects whether the sensed parameter is within a range indicating the presence of drowsiness and applies a wave of electrical stimuli against the human body in response to detection of a sensed parameter within the range. The electrical stimuli cause periodic tightening and relaxing of proximate muscles as the wave progresses in a direction from an inferior location on the human body toward a more superior location.
