    摘要： Ultrasound catheter devices and methods provide enhanced disruption of blood vessel obstructions. Generally, ultrasound catheters include an elongate flexible catheter body with one or more lumens, an ultrasound transmission member extending longitudinally through the catheter body lumen and a distal head coupled with the transmission member and positioned adjacent the distal end of the catheter body for disrupting occlusions. Improved features of ultrasound catheters include prevention of independent rotation of the ultrasound transmission member, a safety anchor for the distal head, a one-piece transmission member/distal head and the like.

    摘要： First, a first electrode layer 4, a piezoelectric layer 5, a second electrode layer 6 and an oscillation layer 7 are stacked in this order over one surface of a silicon substrate 1. Next, an ink chamber partition 8 and a nozzle plate 11 are stacked over the oscillation layer 7. Subsequently, the silicon substrate 1 is ground away to a predetermined thickness from a surface thereof opposite to the first electrode layer 4, and then a remnant silicon substrate 13 is dry etched away. Thereafter, the first electrode layer 4 is patterned to form a plurality of inkjet mechanisms 2, 2, . . . . Finally, the plurality of inkjet mechanisms 2, 2, . . . are divided to simultaneously fabricate a plurality of inkjet heads 3, 3, . . . .

    摘要： A method for making an 8-shaped hole in a bimetallic sleeve, including the steps of preparing two bimetallic tubes, each tube having substantially the same dimension; and also preparing a rear sleeve part, and a front sleeve part; fixing each tube with a plurality of clamping blocks having openings on one side; moving each clamped bimetal tube to a thread cut machine, adjusting the spindle of the thread cut machine to move parallel to the openings on one side of the clamping blocks, and then cutting the clamped tube to form a tube of C-shaped cross section; detaching said tube of C-shaped cross section from said plurality of clamping blocks, and clamping two of said tube of C-shaped cross section together with two fixtures having an 8-shaped cross section; applying spot welding at joints of said two tubes of C-shaped cross section for 6-8 spots to form an 8-shaped hole bushing, and then detaching said two fixtures of 8-shaped cross section; heating the rear sleeve part in a heating furnace for 3-5 hours to reach a temperature of 300-400° C. and a thermal expansion of 0.3-0.5 mm, and then inserting the 8-shaped bushing into the expanded rear sleeve part; and fastening the front sleeve part to the rear sleeve part.
