    摘要： Among other things, there are disclosed embodiments of a valve implant that in particular examples are implantable within a blood vessel, which include a first set of elongate members, a second set of elongate members, and a hood affixed to the first set of elongate members. The first set of elongate members is resiliently deformable, and their distal ends are flared radially outward. The distal ends of the second set of elongate members are distal to the ends of the first set of elongate members. The hood is affixed to the first set of elongate members, and seals against the interior wall of the blood vessel in an expanded configuration. When blood flows from the proximal to the distal side of the valve implant, it presses on the hood, compressing the first set of elongate members, breaking the seal.

    摘要： A system for use with ultrasound procedures including an ultrasound control and/or imaging system which has a microminiature motor, a rotatable reflector and a stationary ultrasound transducer. The transducer may be placed between the motor and the reflector, so as to eliminate the need for placement of wires or other artifact-creating items in the path of ultrasound signals. In particular embodiments, such systems can be incorporated in or retrofitted to commercially standard diagnostic and therapeutic catheters or other housings. Examples can be used in variety of ultrasound procedures, e.g. to perform intravascular ultrasound (IVUS) imaging.

    摘要： Among other things, there is disclosed structure and methods for registering images obtained through internal (e.g. intravascular) ultrasound devices. Embodiments of a device with a rotating ultrasound beam is provided, with a wall of the device being anisotropic in ultrasound passage. As examples, a cable opaque to ultrasound is attached along the wall of the device, so that the ultrasound beam at the location of the cable is blocked, reflected or scattered. As another example, a thin film of metallic material is placed on or in the wall to allow a portion of the beam to be blocked or attenuated. The imaging system recognizes the changes to the signals made by the anisotropic wall, and registers successive images according to those changes.

    摘要： Systems and methods for treating a blood clot positioned within a blood vessel are disclosed. In one embodiment, a balloon member is positioned on a distal end region of a catheter and an ultrasound emitting element is positioned within the balloon member and arranged for actively emitting ultrasound. In some exemplary embodiments, the disclosure provides a multi-wall balloon member and a multi-lumen catheter with at least one and/or all cavities of the balloon member arranged for heat transfer with the ultrasound emitting element. The disclosure also provides catheter arrangements with an ultrasound emitting element arranged to heat tissue adjacent to the balloon member. Additionally, in some embodiments, at least one and/or all walls of the balloon member have apertures arranged to release a therapeutic agent such as a thrombolytic drug.

    摘要： There are disclosed embodiments of devices and methods for imaging the inside of a body part, particularly a blood vessel. In particular embodiments, a catheter has a tip chamber, within which is an ultrasound transducer mounted on a pivot mechanism, a motor for turning the transducer, and an implement for pivoting the transducer. Examples of such an implement are a linear motor, a shaft or filament, and the pivot mechanism may be biased to return to a base position when the implement is not pivoting the transducer. In other embodiments, a mirror reflecting ultrasound signals from the transducer may be rotated and/or pivoted, using similar mechanisms.
