  • Patent number: 12543940
    Abstract: A drive assembly for driving an imaging catheter has a rotatable fiber and a rotatable drive shaft. The drive assembly includes a fiber optic rotating junction and a motor configured to rotate the rotatable portion of the fiber optic rotating junction. In some embodiments, the drive assembly includes a sensor configured to detect a rotational position of the fiber optic rotating junction and a processor configured to obtain the detected rotational position and stop the motor only when the fiber optic rotating junction is in a predetermined rotational position. In some embodiments, the motor includes a hollow shaft through which at least a portion of the fiber optic rotating junction extends.

  • Patent number: 7419501
    Abstract: A method of deploying a prosthesis includes engaging a hub assembly of a handle to a threaded outer surface of a slide shaft of the handle; rotating the hub assembly to cause axial translation of the hub assembly and a sheath coupled to the hub assembly to initiate deployment of the prosthesis; disengaging the hub assembly from the threaded outer surface by pivoting a thread tooth of the hub assembly out of threaded engagement with the threaded outer surface; and sliding the hub assembly on the slide shaft to further retract the sheath and complete deployment of the prosthesis.

  • Patent number: 6808088
    Abstract: A spigot device for a liquid container includes a single-piece molded conduit confining a primary passage and a channel which are surrounded by an outer surrounding wall and which are not communicated with each other within the conduit. An intake end of each of the primary passage and the channel is in fluid communication with a bottom outlet of the container. An exit end of the primary passage is in fluid communication with a fluid passage in which a valve body is disposed to control flow of liquid from the container into a spout. An upright branch tube is in fluid communication with the channel to permit the liquid in the container to flow into the branch tube so that the level of the liquid in the container can be monitored by observing the level of the liquid in the branch tube.

  • Patent number: 6520368
    Abstract: A thermos includes a container detachably mounted on a stand via a coupling member that is formed with a plurality of angularly spaced apart elongated slots, each of which has an enlarged end and a reduced extension. A plurality of studs project from a top seat of the stand into the elongated slots, respectively. The container is rotatable relative to the stand between an engaging position, in which each stud anchors on the reduced extension of a respective one of the slots, and a disengaging position, in which each stud is aligned with the enlarged end of the respective one of the slots.

  • Patent number: 6123196
    Abstract: A plurality of insulating jugs are stackable one over the other. Each of the insulating jugs includes a jug body and a lid. The jug body has a top, a bottom, a receiving chamber, and a pouring opening disposed adjacent to a top of the jug body over the receiving chamber. The lid is disposed on the top of the jug body and has a seat member engaging the jug body over the pouring opening, a displaceable closure member disposed below the seat member and movable to close and open the pouring opening, and an operating lever extending over the seat member and connected to the closure member to actuate the closure member. A hollow cap is disposed over the seat member. The cap has a slot for outward extension of the operating lever from the closure member, and an upwardly projecting central boss. The central boss has a flat top face that is substantially flush with a part of the operating lever when the operating lever closes the pouring opening.
