For intraluminal ultrasound probes, two long-thin arrays (e.g., 1D arrays) are provided in the intraluminal ultrasound probe for bi-plane imaging. The arrays are rotatable relative to each other so that during insertion the arrays align to be long and thin, allowing the shaft of the probe to be narrow. For bi-plane imaging after insertion, one array is rotated relative to the other array, defining two non-parallel imaging planes.

A catheter-based imaging system comprises a catheter having a telescoping proximal end, a distal end having a distal sheath and a distal lumen, a working lumen, and an ultrasonic imaging core. The ultrasonic imaging core is arranged for rotation and linear translation. The system further includes a patient interface module including a catheter interface, a rotational motion control system that imparts controlled rotation to the ultrasonic imaging core, a linear translation control system that imparts controlled linear translation to the ultrasonic imaging core, and an ultrasonic energy generator and receiver coupled to the ultrasonic imaging core. The system further comprises an image generator coupled to the ultrasonic energy receiver that generates an image.

Methods and apparatus are provided for electrically addressing multiple ultrasonic transducers that are connected to a common electrical channel and housed within an imaging probe. An imaging probe may comprise an imaging ultrasonic transducer and a moveable element for controlling the direction of an emitted imaging beam, and an angle sensing ultrasonic transducer, where the angle sensing ultrasonic transducer is configured for determining the direction of an ultrasonic imaging beam. The angle-sensing transducer may be configured to direct an angle sensing ultrasonic beam towards an acoustically reflective substrate and provide a signal by detecting a reflected ultrasonic beam reflected from the acoustically reflective substrate, where the acoustically reflective substrate is positioned relative to the movable element such that motion of the movable element produces a change in the signal.

An endoscope add-on assembly adapted to be attached to a target endoscope. The assembly includes an ultrasound imaging sub-assembly, including a communications cable connected to an ultrasound imaging head and an imaging head movement sub-assembly, including a conduit, holding a tension member that is attached to the ultrasound imaging head. Further included are connective elements, adapted to permit the endoscope add-on assembly to be attached to the target endoscope. Finally, the imaging head movement sub-assembly is detachable from the ultrasound imaging sub-assembly, thereby permitting the imaging head movement subassembly to be processed separately from the ultrasound imaging sub-assembly, after use.

An ultrasound catheter and an ultrasound catheter system that can acquire an image of an observation target with high accuracy when inserted into a large inner lumen. An ultrasound catheter includes: an outer sheath having an accommodation lumen; an inner sheath that can move along an axis; a drive shaft that can rotate in the inner sheath and the outer sheath; and a transducer that is disposed in the accommodation lumen and fixed to a distal end of the drive shaft. The outer sheath includes a first bent portion bent and shaped in advance at a predetermined angle on a proximal side of a most distal end of the accommodation lumen, and a first tubular portion and a second tubular portion positioned on a distal side of the first bent portion and on the proximal side of the most distal end of the accommodation lumen.

A system includes an ultrasound probe comprising an ultrasound transducer, a first motor configured to rotate the ultrasound transducer around a horizontal axis to scan a plane, and a second motor configured to rotate the ultrasound transducer around a vertical axis to move to a different plane. The system further includes a controller unit configured to select a number of scan planes for an interlacing scan to scan a volume of an area of interest in a patient's body using the ultrasound probe; select an interlacing factor for the interlacing scan; divide the scan planes into groups of scan planes based on the interlacing factor; and perform the interlacing scan by controlling the first motor and the second motor, wherein the first motor moves in a first direction for at least some of the scan planes and in a second direction for other ones of the scan planes.

An endoscope add-on assembly adapted to be attached to a target endoscope. The assembly includes an ultrasound imaging sub-assembly, including a communications cable connected to an ultrasound imaging head and an imaging head movement sub-assembly, including a conduit, holding a tension member that is attached to the ultrasound imaging head. Further included are connective elements, adapted to permit the endoscope add-on assembly to be attached to the target endoscope. Finally, the imaging head movement sub-assembly is detachable from the ultrasound imaging sub-assembly, thereby permitting the imaging head movement subassembly to be processed separately from the ultrasound imaging sub-assembly, after use.

A catheter includes: a shaft for insertion into an organ of a patient, and first and second position sensors. The shaft includes: (a) an inner shaft, which is configured to be deflected relative to an axis of the shaft, and (b) an outer shaft, which is coupled to a distal tip of the catheter and is configured to be: (i) coaxially disposed around the inner shaft, (ii) deflected together with the inner shaft, and (iii) rotated about the axis relative to the inner shaft. The first position sensor is coupled to the distal tip and is configured to produce a first signal, and the second position sensor is coupled to the inner shaft, and is configured to produce a second signal.

The present disclosure describes an ultrasound imaging system configured to identify a scan line pattern for imaging an object or feature thereof. The system may include a controller that controls a probe for imaging a volume of a subject by transmitting and receiving ultrasound signals in accordance with a plurality of scan line patterns. One or more processors communicating with the probe may generate a plurality of image data sets based on the signals received at the probe, each data set corresponding to a discrete scan line pattern. These data sets are assessed for a target characteristic specific to the object targeted for imaging. One the data set that includes the target characteristic is identified, the one or more processors select the scan line pattern that corresponds the identified image data set. This scan line pattern may then be used for subsequent imaging of the volume to view the object.

Medical devices that include a medical tool, a handle and a flexible cable bundle passing through the handle. The handles and cable routing therethrough are adapted to reduce noise within the cable.
