    摘要： Systems and methods include positioning of a catheter lumen in a first position with respect to a thrombus (420), the catheter lumen defined by a catheter (440), initiating of evacuation of a tubing lumen (460a), where the tubing lumen is not in fluid communication with the catheter lumen, determination that a pressure within the tubing lumen is equal to or less than a target aspiration pressure, and, in response to the determination that the pressure within the tubing lumen is equal to or less than a target aspiration pressure, automatic establishment of fluid communication between the tubing lumen and the catheter lumen.

    摘要： The present invention provides a normally-closed flow rate control valve capable of precisely and quickly transmitting a change in length of a piezoelectric element without thermal influence. A flow rate control valve (A) includes a base block (1) and a valve opening/closing mechanism (10). The base block (1) is provided with a valve chamber (4) in which a valve seat (3) through which a liquid raw material L flows, and a diaphragm (5) that is brought into contact with or separated from the valve seat (3) so as to close/open the valve seat (3) are installed. The valve opening/closing mechanism (10) includes a slide bearing part (20), a support post part (30), a piezoelectric actuator part (40), and a valve-actuating part (50). The slide bearing part (20) is installed on the base block 1 and is provided with a bearing (24). The support post part (30) includes a support post (31) that is inserted slidably in the bearing (24) and that moves upward and downward in a diaphragm direction. The piezoelectric actuator part (40) is equipped with a piezoelectric element (45) that presses up the support post part (30) in such a direction as to separate the support post part (30) from the diaphragm (5). The valve-operating part (50) performs opening/closing drive of the diaphragm (5) along up-and-down movement of the support post part (30). The support post (31) is made of a low thermal expansion member.
