  • Patent number: 11065375
    Abstract: A blood oxygenator is disclosed comprising a housing, a blood inlet, a blood outlet, a spiral volute, a gas inlet, an oxygenator fiber bundle, and a gas outlet. The housing encloses the fiber bundle and provides the structure for the blood flow path and connectors. The fiber bundle comprises gas-exchange membranes which transfer oxygen to the blood and remove carbon dioxide when the blood flows across the membranes. The spiral volute guides the blood to flow through the fiber bundle. A gas flow chamber receives sweep gas containing oxygen and distributes the sweep gas into the fiber membranes, which gas is then exchanged with the blood being oxygenated.

  • Patent number: 11065120
    Abstract: Described herein are methods and apparatus for approximating targeted tissue using locking sutures. The locking sutures can be configured to receive suture ends that are interweaved through portions of the locking sutures. In a pre-deployment configuration, a locking suture can slide along suture tails and can be positioned at a target location within a target region. Once a desired position and/or tension is achieved, the locking suture can be transitioned to a post-deployment configuration where the locking suture constricts around the suture tails to inhibit relative movement between the suture tails and the locking suture.

  • Patent number: 11045428
    Abstract: Metastatic triple negative breast cancer (TNBC) still carries a dismal prognosis with the current treatment paradigms. The effectiveness of drug treatment for many solid tumors such as TNBC is limited by tumor heterogeneity, lack of tumor specificity, off-target toxicities, and transient therapeutic action(s). Strategies that provide tumor-specific, sustained concentrations of drugs to the tumors and tumor receptor-specific binding, while reducing off-target effects are needed to ensure sufficient tumor cell uptake within the primary and metastatic tumor microenvironment. The decreased non-specific adhesivity, receptor-targeted nanoparticle formulations (“DART” nanoparticles) of the invention were assessed for clinical potential in directing biological agents to the cell surface receptor Fn14, which is expressed in many solid cancer types, including TNBC primary tumors and metastatic lesions.

The method further includes applying, on the processor, coefficients to the values for the one or more parameters. The method further includes determining, on the processor, second data that indicates a prediction that the caregiver will order the blood transfusion during the treatment based on applying the coefficients to the values. The method further includes presenting on a display device output data based on the second data. An apparatus is also provided for predicting that the caregiver will order the blood transfusion during the treatment.

  • Patent number: 11033703
    Abstract: Techniques for emergency apneic oxygenation include a cannula having a longitudinal inner passage with an inner diameter. A distal portion has a first outer diameter greater than the inner diameter, and is made of shape memory material shaped to bend in a first direction along the inner passage. A cannula base has a second outer diameter greater than the first outer diameter. A distance from a distal end of the cannula to a proximal end of the distal portion of the cannula is less than a distance from a surface of a throat of a subject to a distal surface of an airway of the subject. The inner passage is configured to pass a catheter connected at a proximal end to an oxygen source. In various embodiments, the cannula is used with a trocar and, optionally, a system base, or supplied in a kit with a catheter.

  • Patent number: 11026599
    Abstract: Techniques are provided for assessing a risk of fall based on tracking data of a subject tracking a moving target. Tracking data of a first subject to the moving target is determined based on sensing a body of the first subject that measure a position of one or more body segments at time increments over a time period. A response of the first subject is characterized based on the tracking data of the first subject. Tracking data of a second subject to the moving target is determined based on sensing a body of the second subject that measure a position of one or more body segments at each time increment over the time period. A risk of fall of the second subject is determined based on the response of the first subject and the response of the second subject.

  • Patent number: 11026672
    Abstract: Described herein are methods and apparatus for approximating targeted tissue by intertwining two or more sutures together. The sutures are attached to the targeted tissue and routed to a twister device. The twister device secures end portions of the sutures and twists them to intertwine the sutures. Controlling the number of twists provides control over the forces applied to the targeted tissue. In conjunction with visualization feedback, real-time adjustments can be made to achieved targeted results, such as elimination of mitral regurgitation when the disclosed methods and apparatus are applied to mitral valve repair.

  • Publication number: 20210161944
    Abstract: Methods of alleviating or prophylactically blocking pain through the alteration of certain metabolic pathways in a subject experiencing pain or expecting to experience pain are disclosed. In particular, methods of increasing the amount of the neutral amino acid transporter ASCT2 in neurons are disclosed. Increased glutamine uptake by neurons leads to reduced extrusion of lactate and protons into the extracellular space and by extension, reduced sensitization of the neurons. Reduced sensitization of the neurons lessens the feeling of pain in the subject.
