Abstract: A method of alerting a user to the existence of an artificially induced neuromuscular response in a subject includes: generating a series of electrical stimuli at a predetermined period with an electrode disposed at a distal end portion of an elongate medical device; detecting a series of mechanomyographic (MMG) responses of the subject using a mechanical sensor, each MMG response indicative of a contraction of a muscle of the subject; determining a degree of statistical confidence that the detected series of MMG responses was artificially induced by the series of electrical stimuli; and outputting, to the user, both an alert that a series of MMG responses has been detected, and the determined degree of statistical confidence that the detected series of MMG responses was artificially induced by the series of electrical stimuli.

Abstract: Methods for dynamically evaluating blood flow are provided. The method may include injecting Indocyanine Green (ICG) into the bloodstream of a patient, such that the ICG perfuses into a tissue of the patient. ICG images of the tissue may be recorded and stored, such that a user may select a range of stored ICG images. Data indicative of the selected range of stored ICG images is automatically normalized and background-filtering, and a dynamic representation of the ICG perfusion may be generated as a function of time based on the normalized and filtered data. As such, a clinical decision may be made based on the dynamic representation of the ICG perfusion.

Abstract: A method for identifying and treating a neural pathway associated with chronic pain via nerve stimulation and brain wave monitoring of a mammalian brain is described. The method includes positioning a probe to stimulate a target nerve, wherein the target nerve is suspected of being a source of chronic pain; delivering a first nerve stimulation from the probe to the target nerve, wherein the first nerve stimulation is sufficient to elicit a chronic pain response in the brain; and monitoring for evoked potential activity in the brain as a result of the first nerve stimulation. The method can also include delivering second and third nerve stimulations to confirm the correct identification of the neural pathway and to treat the chronic pain, respectively. A system and apparatus for performing a procedure to identify and treat a nerve that is the source of chronic pain are also described.

Abstract: System and method for determining breathing rate as biofeedback is provided. First biomarker, second biomarker, third biomarker and fourth biomarker is extracted by computation engine from physiological parameters associated with subject by applying pre-defined set of rules. A first value is computed by feedback unit as a function of second biomarker, third biomarker and fourth biomarker.

Second value is computed by maximizing time domain parameter of fourth biomarker and minimizing frequency domain parameter of fourth biomarker based on correlation. Second value indicates reduced stress level of subject. Biofeedback is transmitted by feedback unit to cue generation unit which represents quantified data determined based on second value. The quantified data is indicative of modified second biomarker.

Abstract: A housing has a spiral passageway for a catheter that is manually extracted from the housing by means of a wheel having a textured circumferential surface and mounted on a shaft that extends through a non-circular bearing defined in an outer portion of the housing. An inner portion of the wheel extends into the spiral passageway adjacent the wire catheter and an outer portion of the wheel outwardly from the housing whereby the upper surface of the knob can be manipulated in one direction and the wire catheter below the knob will be advanced in the opposite direction. The non-circular bearing has a generally circular outer portion in which the textured surface of the knob is only intermittently in contact with the catheter whereby the wire catheter may be advanced, and a generally linear inner portion sloping inwardly towards the catheter.

Abstract: Accurate measurement of pupillary distance, PD, is necessary to make prescription eye glasses as well as configuring VR headsets, and using other binocular optical devices. Today, many people are ordering eyeglasses on line and obtaining their PD is often problematic for a number of reasons as the prior art fails to provide consumer friendly PD measurement systems. A disclosed eyeglass frame system comprises reference marks of known locations upon the frames. A smart phone may be used to locate the consumer's pupils, while the consumer is wearing the frames. The consumer's pupils may be marked or tagged upon a digital image of the consumer wearing the frames. By use of angles in the sight lines of the camera lens and other variable values and the known relative distances of the frame markings, a consumer's pupillary distance can be quickly and accurately derived.

While the dilator is in muscle, a system may communicate (a) a first series of unequal current amplitude applications (e.g., a series including 0.5, 7, 3, 5 mA applications) to the first electrode to produce at least a first evoked potential (e.g., a MAP or NAP), and (b) a second series of unequal current amplitude applications to the second electrode to produce at least a second evoked potential. The method further includes sensing the first and second evoked potentials and determining a relative location of a nerve based on the sensing of at least one of the first and second evoked potentials.
