摘要： An ultrasound imaging system includes an interventional medical device having a first tracking element that generates tip location data based on a locator field. An ultrasound probe has an ultrasound transducer mechanism and a second tracking element. The ultrasound transducer mechanism has an active ultrasound transducer array that generates two-dimensional ultrasound slice data at any of a plurality of discrete imaging locations within a three-dimensional imaging volume. The second tracking element generates probe location data based on the locator field. A processor circuit is configured to execute program instructions to generate an ultrasound image for display, and is configured to generate a positioning signal based on the tip location data and the probe location data to dynamically position the active ultrasound transducer array so that the two-dimensional ultrasound slice data includes the distal tip of the interventional medical device.

摘要： Provided herein is a catheter assembly including, in some embodiments, a core wire configured for linear actuation and a damping mechanism around the core wire. The core wire includes a proximal end with a sonic connector configured to couple to an ultrasound-producing mechanism. The core wire includes a distal end configured to modify intravascular lesions with vibrational energy from the ultrasound-producing mechanism. The damping mechanism includes a gasket system and a retainer to retain the gasket system in a damping-mechanism bore of the catheter assembly. The damping mechanism is around a proximal-end portion of the core wire, where the damping system can provide a compressive force sufficient to dampen transverse wave-producing vibrational energy in the proximal-end portion of the core wire without restricting the linear actuation of the core wire through the damping mechanism including extension and retraction of the core wire through the damping mechanism.

摘要： A method of generating a 3D ultrasound image includes acquiring a 3D volumetric data set corresponding to a 3D imaging volume of an ultrasound probe in a 3D detection volume; acquiring a position of the ultrasound probe with respect to the 3D detection volume; acquiring a position of an interventional medical device with respect to the 3D detection volume; determining a position of the interventional medical device relative to the 3D imaging volume of the ultrasound probe; determining an interventional medical device-aligned plane that intersects with a longitudinal axis of the interventional medical device; extracting a texture slice from the 3D imaging volume for a corresponding interventional medical device-aligned plane positional and rotational orientation; mapping the texture slice onto the interventional medical device-aligned plane; and rendering the interventional medical device-aligned plane as a 3D ultrasound image and displaying the rendered 3D ultrasound image on a display screen.

摘要： A vascular occlusion treatment system includes an ultrasound imaging system having an imaging control circuit communicatively coupled to an ultrasound imaging probe and to a display screen, and an ultrasonic vibration system having an ultrasonic generator operatively coupled to a medical ultrasonic object, such as an ultrasonic catheter. The ultrasonic catheter has a corewire with a distal tip. The ultrasonic generator has a generator control circuit that alternatingly switches between an ultrasonic work frequency and a tracking frequency. The generator control circuit sends a notification to the imaging control circuit when the generator control circuit has switched from the ultrasonic work frequency to the tracking frequency. The imaging control circuit responds by initiating a search in an ultrasound imaging space to locate the distal tip that is vibrating at the tracking frequency, and indicating a location of the distal tip in the ultrasound image displayed on the display screen.

摘要： An ultrasonic catheter assembly includes a sheath having a sheath lumen. A core wire is at least partially disposed within the sheath lumen. The core wire has a proximal portion and a distal portion. The proximal portion of the core wire is configured to be coupled to an ultrasound-producing mechanism. A working length of the distal portion of the core wire extends distally from the sheath. The working length is configured for longitudinal displacement, transverse displacement, or a combination of longitudinal and transverse displacement, in accordance with a plurality of output modes for vibrational energy supplied to the core wire proximal portion by the ultrasound-producing mechanism.
