Disclosed herein is an implantable port and an implantable port-detecting device (“IPDD”). The implantable port includes a housing and a septum over a portion of the housing. At least one of the housing or the septum incorporates a contrast agent for locating the septum of the implantable port when the implantable port is implanted in a patient. The IPDD includes a light source, a light detector, and a display configured to display a presence of the implantable port. The light source is configured to emit light in a near-infrared (“NIR”) range of wavelengths as incident light for absorption by the contrast agent. The light detector is configured to detect light in the NIR range of wavelengths including luminescent light emitted by the contrast agent. The display is configured to display a presence of the implantable port when the luminescent light from the contrast agent is detected by the light detector.

An ultrasound imaging system includes an interventional medical device having a first tracking element that generates tip location data based on an EM 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 EM 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.

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.

A system including a console and a catheter assembly. The console may include an ultrasound-producing mechanism configured to convert an electric current into a vibrational energy. The console also may include a driving-parameter modifier configured to modify driving parameters to selectively provide one or more output modes for the vibrational energy. The catheter assembly may include a sheath including a sheath lumen and a core wire at least partially disposed within the sheath lumen. The core wire may include a proximal portion and a distal portion of the core wire, wherein the proximal portion of the core wire is coupled to the ultrasound-producing mechanism. A working length of the distal portion of the core wire beyond the sheath may be configured for longitudinal, transverse, or longitudinal and transverse displacement in accordance with the one or more output modes for the vibrational energy to effect different intravascular lesion-modification procedures.
