  • Patent number: 9186068
    Abstract: A patient monitoring system may provide photoacoustic sensing based on an indicator dilution to determine one or more physiological parameters of a subject. The system may detect an acoustic pressure signal, which may include one or more thermo-dilution responses, one or more hemo-dilution responses, or a combination thereof. For example, a thermo-dilution indicator and/or a hemo-dilution indicator may be used to determine one or more hemodynamic parameters. In a further example, an isotonic indicator and a hypertonic indicator may be used to determine one or more hemodynamic parameters of the subject.

  • Patent number: 8535366
    Abstract: The present invention, in an exemplary embodiment, provides a delivery system and novel handle configuration for the delivery system that facilitates repeatable placement of implantable devices. In particular, in optical embodiments, the handle allows for the reversible coupling of scopes directly to the handle to enhance physician control during placement. The delivery system also allows for one-handed manipulation as finger action can be used to engage and disengage the scope as well as actuate the extent of implantable device deployment. Exemplary delivery systems are flexible, durable and/or assure proper installation of one or more implantable devices in a single procedure. Moreover, the preferred embodiments of the delivery system provides for the reloading of the delivery device with additional implantable devices for additional interventional procedures, resulting in a substantially reusable delivery device.

  • Patent number: 8506496
    Abstract: The invention relates to a method and an apparatus for determining the systolic phase interval (SP) of an arterial pressure curve with a starting point (t0) of the systolic phase interval (SP) and an end point (tN) of the systolic phase interval (SP) wherein a QT interval is defined as the start of the Q wave and the end of the T wave in the hearts electrical cycle and wherein the determination of the end point (tN) of the systolic phase interval (SP) is restricted to the measured points of arterial pressure which fulfill the condition that the difference in time between the end point (tN) to be determined of the systolic phase interval (SP) and the starting point (t0) of the systolic phase interval (SP) is smaller than the QT interval.

  • Publication number: 20070106181
    Abstract: A lumen measuring device generally includes a central member dimensioned to extend into a lumen and an elongate outer member having a flexible region configured to flex outward from the central member in response to retraction of the central member. In measuring a lumen, the flexible region is caused to contact the lumen. The lumen may be contacted by linear segments that hinge or by members that bow arcuately. A polygon, such as a triangle, may be defined by portions of the outer member and the central member. A handle assembly may be provided by which the disposition of the central member relative to the outer member may be adjusted. Indicators may be defined by the central member and outer member by which the disposition of the central member and by which the diameter of a lumen may be determined.

  • Patent number: 6989498
    Abstract: The present invention concerns a method and a device for locking a disconnecting breaker. During locking of a single-poled or multiple-poled disconnecting breaker, the actuator of the breaker is first locked both electrically and mechanically. When the breaker is in the open position, the distance between the contacts of the breaker comprises the conductor spacing for the isolation function. The electrical and mechanical locking of the actuator is indicated both electrically and mechanically. Subsequently, the link system of the breaker is mechanically locked. The link system is locked in the interlocked position. Locking of the link system is indicated by at least one indicator. Locking of the actuator of the breaker can be controlled manually via a key- and lock device, or remotely.
