  • Patent number: 9907542
    Abstract: A biopsy device includes a needle extending distally from a body. The needle includes a transverse aperture, a first lumen, and a second lumen. A cutter is movable within the first lumen to sever tissue protruding through the transverse aperture. A valve assembly is operable to change the pneumatic state of the second lumen. The valve assembly includes a valve body and a translating member slidably disposed in a bore of the valve body. The valve body includes a first port and a second port. The first port is in fluid communication with the second lumen of the needle. The second port is in fluid communication with atmospheric air. The translating member selectively couples the first port with the second port based on the longitudinal position of the translating member within the bore. The translating member translates relative to the valve body based on the position of the cutter.

  • Patent number: 9883831
    Abstract: Cognitive tests are loaded onto myriad touch screen client computing devices. Patients are administered the tests using the touch screen devices, and their performance is captured and transmitted to cloud servers that store the patient information of all the touch screen devices in a database. In addition to cognitive test results, touch screen devices may also transmit patient medical information for storage in the database. Consequently, the database includes a large population of performance and medical data that can be evaluated to gain insights into cognitive disorders and create more effective digital tests for their diagnosis and treatment.

  • Patent number: 9872640
    Abstract: Embodiments for characterizing ear canal acoustic impedance and reflectance by pole-zero fitting are disclosed. Embodiments include transmitting an acoustic signal into an ear canal by a transducer having an acoustic source pressure. Further embodiments, measure complex cavity pressure, P(f), response based on the transmitted acoustic signal reflected by eardrum using an acoustic measurement device. Additional, such embodiments, calculate complex acoustic reflectance (CAR) based on the P(f). Other embodiments determine number of poles and zeroes of CAR pole-zero model to reduce residual error between the CAR pole-zero model and CAR data stored in memory within a threshold. Also, embodiments verify the residual error of CAR pole-zero model compared to the CAR data is within the threshold. Further, embodiments factor the CAR pole-zero model into an all pass component and a minimum phase component. Additional embodiments determine ear drum impedance by removing the all phase component of the CAR pole-zero model.

  • Patent number: 9854966
    Abstract: A system and method for determining a subject's attentional response to a stimulus. The method includes measuring microsaccadic eye movement dynamics of the subject, detecting whether a microsaccadic signature (a suppression in microsaccadic rate) is present in the measured microsaccadic eye movement relative to a time of the stimulus, and correlating the subject's attentional response to the stimulus based on the detection. The method further includes determining that the stimulus was sensed if the microsaccadic signature is present and determining that the stimulus was not sensed if the microsaccadic signature is absent.

  • Patent number: 9844362
    Abstract: The present disclosure generally relates to a biopsy needle configured to maximize tissue sampling yield and collect a cohesive unit of sampled tissue. The biopsy needle includes an elongate tubular body comprising a lumen extending therethrough from a proximal open end to a distal open end of the body. The distal end includes first and second tip portions extending therefrom and formed on opposing sides of the needle body. The first tip portion generally extends further from the distal end than the second tip portion, resembling a staggered configuration, resulting in an increased surface area of multiple cutting edges formed between the first and second tip portions on either side of the needle body. Additionally, each of the first and second tip portions defines a penetrating point configured to pierce the tissue to be sampled and further direct sampled tissue towards the lumen of the body to be excised by the cutting edges upon contact therewith.

  • Patent number: 9833163
    Abstract: This invention detects tissue injury by measuring decreased skin conductance as shown by research. Two electrical probes on the device are placed onto a subject's skin. The device sends an electrical microcurrent from one probe, through the subject's skin, to the other probe. A gauge measures the microcurrent in microamps, and a speaker emits a tone with pitch and volume proportional to the percentage of maximum conductance. Per research, the skin conductance will decrease significantly over a site of tissue injury, such as an average of around 70% over a sprained ankle. Also, force gauges measure the force applied to the electrical probes for consistency of measurement. Cotton pads are placed at the tips of the electrical probes for hygiene.

  • Patent number: 9833180
    Abstract: Optical coherence tomography (herein “OCT”) based analyte monitoring systems are disclosed. In one aspect, techniques are disclosed that can identify fluid flow in vivo (e.g., blood flow), which can act as a metric for gauging the extent of blood perfusion in tissue. For instance, if OCT is to be used to estimate the level of an analyte (e.g., glucose) in tissue, a measure of the extent of blood flow can potentially indicate the presence of an analyte correlating region, which would be suitable for analyte level estimation with OCT. Another aspect is related to systems and methods for scanning multiple regions. An optical beam is moved across the surface of the tissue in two distinct manners. The first can be a coarse scan, moving the beam to provide distinct scanning positions on the skin. The second can be a fine scan where the beam is applied for more detailed analysis.

  • Patent number: 9833131
    Abstract: A steerable device, such as a steerable catheter, may include a control handle and an insertion shaft extending outwardly therefrom. In use, the insertion shaft is navigated to an area of interest for examination and/or treatment thereof. The steerable device may include a steering system that controls the deflection angle of the distal end of the insertion shaft in two or more non-planar directions for navigating the insertion shaft to the area of interest. The steering system may also include a locking mechanism for arresting or partially arresting the movement of the distal end of the insertion shaft in a first direction independent of arresting or partially arresting the movement of the distal end in a second non-planar direction.

  • Patent number: 9827051
    Abstract: The description relates to surgical computer systems, including computer program products, and methods for implant planning using captured joint motion information. Data is captured representative of a range of motion of a joint associated with a particular individual, where the joint includes a first bone and a second bone. The first bone of the joint is represented and a first implant model is associated with the representation of the first bone. Based on the captured data, a relationship is determined between the first implant model and a representation of the second bone through at least a portion of the range of motion of the joint. Information is displayed representative of the determined relationship.
