  • Patent number: 10314649
    Abstract: A surgical instrument, such as an electrical ablation device, includes an elongate member having therealong disposed a first electrode extending along an axis. A first expandable portion extends along the axis and defines a first perimeter of the first electrode and has an associated first diameter with respect to the axis. The first expandable portion includes a first framework selectively expandable to transition the first expandable portion from a contracted state to an expanded state. The first framework is selectively contractible to transition the first expandable portion from the expanded state to the contracted state. When the first framework is expanded, the first diameter is expanded and the first expandable portion is transitioned from the contracted state to the expanded state. When the first framework is contracted, the first diameter is contracted and the first expandable portion is transitioned from the expanded state to the contracted state.

  • Patent number: 10315028
    Abstract: A medical electrical lead and a method of its use. The lead has an elongated lead body having an outer circumference and provided with an electrode. A push tube is mounted circumferentially around the lead body and the lead body is longitudinally movable with respect thereto. A fixation helix is mounted to the push tube, extending along a generally helical axis around the outer circumference of the lead body. The lead may be employed by advancing the lead to a desired location for the fixation helix and then rotating the push tube to secure the helix to tissue. The lead body may then be moved longitudinally with respect to the push tube to place the electrode in a desirable location.

  • Patent number: 10300285
    Abstract: Electrical stimulation sources and amplitudes are allocated to implantable electrodes based on impedance values for controlled delivery of electrical stimulation therapy to a patient. Allocation may include assigning implantable electrodes, in a group of active electrodes, to clusters based on impedance values of the electrodes, coupling the electrode clusters to respective stimulation sources, and defining respective stimulation amplitudes delivered by the stimulation sources to the electrode clusters. Each cluster may include electrodes having relatively similar impedance values, such that electrodes in each cluster present less variation in impedance relative to impedance variation across the group of electrodes. With reduced variation in impedance, in some examples, variation in current outflow through electrodes in each cluster may be reduced, promoting more uniform distribution of stimulation current across the group of active electrodes and a more uniform stimulation field.

  • Patent number: 10299736
    Abstract: Methods, devices, and systems according to present principles provide ways to diagnose frailty and assess the severity of its clinical status—e.g., non-frail, pre-frail, and frail, especially as measured and quantified during activities of daily living. Systems and methods according to present principles objectively quantify physical activity behaviors and identify specific motor tasks, which indicate clinical frailty syndrome behaviors such as flopping, cautious-sitting, non-uniform walking fluctuations, cognitive decline, slowness, weakness, and exhaustion. Additionally, the systems and methods allow improved sensitivity and specificity of frailty identification by further assessing physiological parameters such as heart rate, respiration rate, and skin temperature in response to, or recovery from, specific activities.

  • Patent number: 10244958
    Abstract: A cardiac function measurement and evaluation device is provided to measure and evaluate cardiac function in patients with atrial fibrillation, sinus arrhythmia, and the like, using thoracic impedance data and electrocardiogram data. By creating a two-dimensional scatter plot in which (dZ/dt)min values and preceding RR intervals (RR1) corresponding thereto, and the like obtained by thoracic impedance measurement, are plotted, it is possible to visually and easily evaluate the state of cardiac function in patients with atrial fibrillation and sinus arrhythmia. Using the measurement and evaluation device of the present invention makes it possible to perform examinations easily and repeatedly with less burden on patients. Therefore, it is possible to provide very useful information for diagnosing heart disease, selecting drugs, and the like.

  • Patent number: 10232184
    Abstract: A system is provided for testing the electrical integrity of an implanted pacemaker or defibrillator lead. The system includes a container holding an electrically conductive solution, such as a saline solution. A voltage source and two electrodes are provided to pass an electrical current through the solution. To use the system, the proximal end of the electrical lead is disconnected from the implanted electronic device, passed through the saline solution and then electrically connected to a device/monitor. During testing, the device/monitor sends a test pulse through the lead and monitors electrical activity in the lead. To test sequential locations along the length of the proximal segment, the segment is drawn through the saline solution and between the electrodes while test pulses are sent and monitored. The monitor detects abnormal electrical activity in the lead indicative of a break in lead insulation.

  • Patent number: 10076281
    Abstract: A sleep monitoring device (100) is disclosed for measuring a biophysical variable (131) of a living-being (150), comprising at least two pressure sensors (101-103) spatially arranged in a predefined planar geometry. The living-being rests on the supporting layer (199) contacted by the sensors that generate sensor signals in response to pressure caused by the living being via the supporting layer. A processing unit (110) determines the position of the living-being on the supporting layer based on differences between the sensor signals; a magnitude attenuation factor is determined based on the position of the living-being and a position of a sensor; the biophysical variable is determined from a sensor signal generated by that sensor, including a magnitude correction based on the magnitude attenuation factor. The effect of the invention is that only few sensors are needed to measure a biophysical variable accurately, irrespective of the living-being's position on the supporting layer.
