    摘要： An imaging catheter is provided having a distal end portion selectively rotatable relative to a catheter body. A transducer array is supported by the distal end portion so that a corresponding imaging field may be selectively panned about an axis extending distally from the catheter body. The catheter may be advanced within a patient to a desired location. Optionally, the catheter may then be steered, or curved to position the transducer array. Optionally, the catheter may be rotated to further position the transducer array. Then, the imaging field may be panned without manipulation of the catheter body.

    摘要： Actuators employable for oscillating movement of a load. An improved actuator may include at least a first shape memory member that is actuatable to affect at least a portion of the oscillating movement of the load. The actuator may further include a second shape memory member actuatable to affect at least a second portion of the oscillating movement of the load. The utilization of one or more shape memory members facilitates the realization of controllable and reliable oscillating movement of a load in a compact manner. Such actuators may be used in imaging catheters having an ultrasound transducer disposed for oscillating movement to scan across an internal region of interest. Such imaging catheters may be used in generating three dimensional and/or real-time three dimensional (4D) images.

    摘要： An ultrasound catheter probe assembly capable of scanning a three-dimensional volume is provided. The ultrasound catheter probe assembly contains a plurality of ultrasonic transducers disposed along a central axis of the ultrasound catheter probe assembly. The plurality of ultrasonic transducers is disposed on a mechanism operable to reciprocally pivot the plurality of ultrasonic transducers enabling the plurality of ultrasonic transducers to scan a three-dimensional volume. A helically disposed electrical interconnection member may be disposed about a pivot axis of the plurality of ultrasonic transducers and may electrically interconnect the plurality of ultrasonic transducers to an ultrasound imaging system. The ultrasound transducer catheter probe assembly may be fluid-filled and contain bubble position control and fluid expansion compensation features.
