    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 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: A method for separating particles from a flowing fluid suspension comprises the steps of providing an elongated chamber having closed first and second ends, flowing into the elongated chamber a fluid medium in which particles to be separated are suspended, and propagating an acoustic wave through the flowing fluid medium in the chamber. The acoustic wave is directed generally along the length of the chamber and is varied in frequency within a desired frequency range including a frequency resonant to the chamber to produce stationary coincidence excitations that separate particles from the fluid medium and urges the separated particles toward the second end of the chamber. The method also includes the steps of removing the fluid medium from the first end of the chamber and removing from the chamber the particles urged toward the second end of the chamber. The apparatus for separating particles from a flowing fluid comprises a tube having first and second open ends, a first outlet port adjacent the first end, a second outlet port adjacent the second end, and an inlet port intermediate the first and second end. Each end of the tube is closed by a spacer bonded to the tube end. A transducer is bonded to each spacer.
