  • Patent number: 10293138
    Abstract: A medical device control handle has a first actuation assembly and a second actuation assembly, wherein each assembly has a shaft that is axially aligned but not rotationally coupled with the other shaft. The first actuation assembly includes a first actuation member and a clutch mechanism having a friction disk for generating frictional torque in rendering the first actuation member self-holding. The first actuation member has a cam portion adapted to impart translational motion and rotational motion for disengaging the clutch mechanism upon pivotation of the first actuation member, thus allowing rotation of the first shaft to manipulate a feature of the medical device, for example, deflection. The second actuation assembly includes a second actuation member and a translating member that is responsive to rotation of the second shaft so as to manipulate another feature of the medical device. The second actuation member is also self holding.

  • Patent number: 10285756
    Abstract: In various embodiments, a catheter comprising an expandable electrode assembly or basket is provided. In specific embodiments, the basket is particularly useful for mapping electrical activity at one or more locations within the heart. The basket can comprise a plurality of bendable or deflectable arms. At least one of the arms may have varied flexibility over its length in the form of one or more discontinuities of stiffness or flexibility at an elbow region or other variances in flexibility over the arm's length. Such variance in flexibility may allow the arm to assume a different bent configuration or respond to external factors more positively than possible with an arm having a static or near static flexibility or stiffness over its length.

  • Patent number: 10278606
    Abstract: Physiological monitoring can be provided through a lightweight wearable monitor that includes two components, a flexible extended wear electrode patch and a reusable monitor recorder that removably snaps into a receptacle on the electrode patch. The wearable monitor sits centrally on the patient's chest along the sternum oriented top-to-bottom. The placement of the wearable monitor in a location at the sternal midline, with its unique narrow “hourglass”-like shape, significantly improves the ability of the wearable monitor to cutaneously sense cardiac electrical potential signals, particularly the P-wave and the QRS interval signals indicating ventricular activity in the ECG waveforms. In particular, the ECG electrodes on the electrode patch are tailored to be positioned axially along the midline of the sternum for capturing action potential propagation in an orientation that corresponds to the aVF lead used in a conventional 12-lead ECG that is used to sense positive or upright P-waves.

  • Patent number: 10278603
    Abstract: A system and method for secure physiological data acquisition and storage. An identifier of a physiological monitoring patch is obtained by a programming wand, the patch configured to store the identifier within a cryptographic circuit. A password for accessing physiological monitoring data collected using that patch is generated based on at least a portion of the identifier, the password is encrypted using a secret key, and the encrypted password is loaded into the cryptographic circuit. The key is loaded onto a monitor recorder that couples with the patch and obtains the physiological monitoring data using the patch, wherein the monitor recorder offloads the data together with the identifier and the decoded password. The identifier and the password are reported to a server that stores the offloaded physiological monitoring data using the identifier within a secure database and grants access to the data upon receipt of the decoded password.
