  • Patent number: 10182729
    Abstract: The exemplary systems and methods may monitor one or more signals to be used to assess the hemodynamic status of a patient. The one or more signals may be used to calculate, or determine, a plurality of pulse transit times. The plurality of pulse transit times may be used to determine hemodynamic status values that may be indicative of a patient's aggregate hemodynamic status.

  • Publication number: 20180116598
    Abstract: Embodiments describe a method of determining etiology of undiagnosed events comprising monitoring electrocardiogram signals and blood pressure of a patient via a medical device, capturing one or more of an ECG segment and a BP reading in response to a triggering event, classifying one or more of the ECG segment and BP reading as normal or abnormal, and determining etiology of undiagnosed symptomatic events based on the classification. Embodiments further describe a medical device comprising sensors for monitoring ECG signals and BP of a patient, circuitry for capturing one or more of ECG segments and BP readings of a patient in response to a triggering event, and a processor for communicating one of more of captured ECG segments and captured BP readings to a remote monitoring center directly or indirectly where the captured ECG segments and captured BP readings are classified as normal or abnormal.

  • Publication number: 20120283705
    Abstract: A percutaneous delivery tool may be used to implant a medical device, for example, within a subcutaneous space. The percutaneous delivery tool may include a handle, first and second attachment members, and first and second connecting members connecting the attachment members to the handle. In some examples, the first and second attachment members are configured to receive the medical device such that the medical device is positioned between the attachment members. In some additional examples, the first and second connecting members are angled with respect to the handle, the first connecting member is angled with respect to the first attachment member, and the second connecting member is angled with respect to the second attachment member.

  • Publication number: 20120197150
    Abstract: An external physiological monitor continuously senses and monitors cardiac function of a patient to allow detection of cardiac events and the recording of data and signals pre- and post-event. The monitor is connected to and suspended on the patient's body solely by the electrode assembly. Stored diagnostic data may be uplinked and evaluated by the patient's physician utilizing a programmer via a two-way telemetry link. An external patient activator may optionally allow the patient, or other care provider to manually activate the recording of diagnostic data.

  • Publication number: 20120108993
    Abstract: An improved design for subcutaneous monitors that addresses the problem caused by bubbles of air may remain in the pocket in which the device is implanted. As implantable monitors and their associated electrodes are reduced in size, these bubbles may in some cases cover one or both electrodes, interfering with sensing of the ECG signal. The invention addresses this problem by configuring the electrodes to increase the pressure of the electrodes against the tissue above the electrodes relative to the pressures exerted by the adjacent outer facing surfaces of the device.

  • Patent number: 7766826
    Abstract: A system and method for storing and processing physiological data in a medical recording device that allows continuous data collection and storage of such data in multiple time-resolved levels are provided. The method includes: sampling one or more physiological signals at a selected sampling rate; deriving physiological parameter values from the sampled signal; storing the parameter values as they are determined in a temporary memory buffer for a predetermined storage interval; determining a statistical aspect of the stored parameter values upon expiration of the storage interval; and writing the statistical aspect to a long-term memory buffer. A number of long-term memory buffers may be designated for storing a statistical aspect of a physiological parameter at uniquely different time resolutions. The resolution of each long-term memory buffer is determined by the storage interval defined for an associated temporary memory buffer, which stores parameter values from which statistical aspects are computed.

  • Patent number: 7634310
    Abstract: A method and apparatus for detecting atrial arrhythmias include acquiring a cardiac signal comprising R-waves. Differences between pairs of consecutive R-R intervals occurring during a first time interval are computed from the cardiac signal. An atrial arrhythmia is detected subsequent to the first time interval in response to the computed differences. Storage of the cardiac signal is triggered in response to the atrial arrhythmia detection.
