  • Patent number: 12002203
    Abstract: Described are systems and methods for assessing a likelihood of chronic thromboembolic pulmonary hypertension (CTEPH) within a subject patient based upon an analysis of characteristics indicative of chronic thromboembolic pulmonary hypertension within an imaging study of the subject patient. The systems and methods can identify characteristics of one or more anatomical structures within a cardiac region of the subject patient indicative of CTEPH, characteristics of a pulmonary vasculature of the subject patient indicative of CTEPH, and characteristics of a chronic abnormality in a lung of the subject patient indicative of CTEPH. The systems and methods can assess these characteristics to compute the likelihood of CTEPH within the subject patient.

  • Patent number: 11234628
    Abstract: The present invention provides systems and methods for detection and diagnosis of concussion and/or acute neurologic injury comprising a portable headwear-based electrode array and computerized control system to automatically and accurately detect cortical spreading depression and acute neurological injury-based peri-infarct depolarization (CSD/PID). The portable headwear-based electrode system is applied to a patient or athlete, and is capable of performing an assessment automatically and with minimal user input. The user display indicates the presence of CSD/PID, gauges its severity and location, and stores the information for future use by medical professionals. The systems and methods of the invention use an instrumented DC-coupled electrode/amplifier array which performs real-time data analysis using unique algorithms to produce a voltage intensity-map revealing the temporally propagating wave depressed voltage across the scalp that originates from a CSD/PID on the brain surface.

  • Patent number: 9662432
    Abstract: A novel arterial cannula tip includes an elongated body having an expanded four-lobe swirl inducer and a diverging diffuser. The swirl inducer presents micro-scale blood-wetting features that help to enhance the jet or core of the flow of blood sufficiently to delay the onset of turbulence and facilitate a strongly coherent blood outflow jet as it enters the cannulated artery, while the diverging diffuser reduces exit force and promotes and laminar flow which mitigates intimal vascular damage owing to high wall shear stresses at regions of jet impingement. When used in conjunction with an aortic cannula, the device facilitates neuroprotection by way of improved cerebral perfusion.

  • Patent number: 9622821
    Abstract: A method for fusing information related to structural features and characteristics of a biological sample. The resulting fused image may be imported into a surgical navigation technology intra-operatively to aid in surgical interventions by co-registering the fused image with the patient's anatomical features.

  • Patent number: 9179881
    Abstract: A process and a system for assisting a clinician in identification and evaluation of perfusion characteristics of an organ are disclosed. The process and system may be used to extend clinical diagnosis capabilities by augmenting the ability to analyze perfusion images acquired from a radiology imaging modality through the use of the quantification technology as described. Classification of perfusion characteristics of a region of interest is facilitated through the use of a quantitative spatial perfusion characteristics map. The map is generated by a computing device which applies at least one physics-based image processing technique. This map is displayed on a clinician device for review by the clinician to assist in the spatial identification of perfusion abnormalities.
