Abstract: A wearable device to measure a user's physiological parameters comprising one or more biosensors, as well as a light source comprising light emitting diodes, lenses for directing light towards tissue of the user comprising blood vessels, and a detection system receiving reflected tissue light. The physiological parameters, for example hypertension, are measured with a differential measurement. For example, the physiological parameters may be associated with pulse rate and blood flow. The output signal is associated with the physiological parameters, and artificial intelligence may be used in making decisions regarding the output signal. Signal-to-noise ratio of the output signal may be improved by synchronizing the detection system to the light source, increasing light intensity, and detecting a change. The wearable device is configured to determine that is being worn by the user and may be configured to communicate with a smartphone or tablet.

Abstract: A system and method for selectively processing target tissue material in a patient include a laser subsystem for generating an output laser beam and a catheter assembly including an optical fiber for guiding the output laser beam. The beam has a predetermined selected wavelength between 900 nm and 2600 nm. The catheter assembly is sized to extend through an opening in a first part of the patient to a tissue material processing site within the patient. A beam delivery and focusing subsystem includes a focal distance, which may be adjustable, that positions the beam into at least one focused spot on the target tissue material disposed within a second part of the patient for a duration sufficient to allow laser energy to be absorbed by the target tissue material and converted to heat to produce a desired physical change in the target tissue material without causing undesirable changes to adjacent non-target material.
