  • Patent number: 9788792
    Abstract: The present invention relates to a novel approach means of screening various skin surfaces, including hard to reach areas of the human body, as well as more commonly seen areas such as the foot. The present invention can help patients, especially those who are immobile or those with diabetes self-monitor and transmit the skin condition accurately, so that medical providers may assess the risk or presence of skin tissue breakdown. Thus, provision is made for a remote screening device that can be used in telemedicine or home self-monitoring approaches and offers high resolution image, without artifacts or other distortions that might arise from images taken of feet that have been compressed through standing and the like.

  • Patent number: 9393425
    Abstract: Systems and methods define an index of risk for cardiac disease by detecting cellular derangements that may lead to cardiomyopathy, heart rhythm disorders or ischemic heart disease. The markers include fluctuations or abnormal rate-behavior of electrical, mechanical or other measurable biosignals. The invention operates in modes that can be applied to prevent atrial fibrillation or the risk for ventricular arrhythmias. Alternative embodiments are applied to tissue outside the heart such as skeletal muscle, smooth muscle, the central nervous system, the respiratory system, the urogenital system and the gastrointestinal system.

  • Patent number: 9375156
    Abstract: A system to detect a cause of a complex rhythm disorder in a human heart includes a plurality of sensors disposed spatially in relation to the heart, where the signals generated by the sensors are associated with activations of the heart. A processor collects and analyzes the signals to identify a region of the heart having an activation trail that is rotational or radially emanating, where the activation trail is indicative of the complex rhythm disorder and is based on activation times associated with the activations of the heart.

  • Patent number: 9332915
    Abstract: In a system and method for identifying a driver of a source associated with a heart rhythm disorder, data are accessed from a plurality of sensors representing biological activity in the heart. A first region and a second region of the heart are identified as the source of the heart rhythm disorder. If the first region has repeating activation and controls the second region for at least a predetermined number of beats, the first region is identified as controlling the source of the heart rhythm disorder.

  • Patent number: 9282910
    Abstract: A system and method to target a biological rhythm disorder, such as a heart rhythm disorder, include processing cardiac signals via a computing device to determine a shape in a region of tissue defined by a source associated with the biological rhythm disorder that migrates spatially on or within the shape, and identifying at least one portion of the tissue proximate to the shape to enable selective modification of the at least one portion of tissue in order to terminate or alter the heart rhythm disorder.

  • Patent number: 9241667
    Abstract: System, assembly and method are provided to facilitate reconstruction of cardiac information representing a complex rhythm disorder associated with a patient's heart to indicate a source of the heart rhythm disorder. The complex rhythm disorder can be treated by application of energy to modify the source of the rhythm disorder.

  • Patent number: 9220427
    Abstract: In a system and method for reconstructing cardiac activation information, an analysis cardiac signal and a reference cardiac signal are processed to determine a first point of change in a derivative of the analysis cardiac signal with respect to a derivative of the reference cardiac signal. The analysis cardiac signal and the reference cardiac signal are processed to determine a second point of change in a different derivative of the analysis cardiac signal with respect to a different derivative of the reference cardiac signal. An activation onset time is assigned in the analysis cardiac signal at a point based on a mathematical association of the first point of change and the second point of change to define cardiac activation indicating a beat in the analysis cardiac signal.

  • Patent number: 8876753
    Abstract: A peritoneal-based artificial kidney processes peritoneal fluid without need for additional fluids. Spent dialysate is separated into a protein-rich stream and a protein-free stream. The protein-rich stream is regenerated using a sorbent assembly, and its protein composition can be modified by removal of selected protein(s). Alternatively, the spent dialysate is first processed in a sorbent assembly and then separated into the protein-rich and protein-free streams. Immobilization of urease allows more protein rich fluid to be regenerated and re-circulated into the peritoneal cavity for toxin removal and allows practicable development of portable and wearable artificial kidneys.

  • Patent number: RE46211
    Abstract: A monoclonal antibody, 3E10, and active fragments thereof that selectively are transported in vivo to the nucleus of mammalian cells without cytotoxic effect are provided. The antibody and other molecules that bind to a variant of myosin IIb heavy chain found in the nucleus of skeletal muscle cells are useful as a non-viral delivery vector to target skeletal muscle in vivo. By contrast, in vitro the monoclonal antibody penetrates and is transported to the nucleus of multiple cell lines derived from different tissue types and can be used in screening tests to identify molecules that modulate growth of cells, such as cancer cells. Non-cytotoxic vectors for delivering a drug, polynucleotide or polypeptide selectively to skeletal muscle cells are also provided.
