    • Apparatus for use in cannulation of blood vessels includes a hollow needle having a sharpened end for penetrating tissue, a trocar including a transducer mounted on one end for positioning within the hollow needle for transmitting and receiving ultrasonic waves through the sharpened end of the needle. The trocar further includes a support rod for the transducer and ultrasound damping material attaching the transducer to the support rod. Electrical conductors are provided through the support rod or on the surface of the support rod in contact with electrodes on the front and back surfaces of the transducer for transmitting electrical signals to and from the transducer. A syringe portion is detachably detached from the needle for receiving the back flow of blood when the needle is inserted into a blood vessel.
    • 用于血管插管的装置包括具有用于穿透组织的锋利末端的中空针,套管针,其包括安装在一端上的换能器,用于定位在中空针内,用于通过针的尖端发射和接收超声波。 套针针还包括用于换能器的支撑杆和将换能器附接到支撑杆的超声阻尼材料。 电导体通过支撑杆或支撑杆的表面设置,与传感器的前表面和后表面上的电极接触,用于将电信号传送到换能器和从换能器传送电信号。 当针插入血管时,注射器部分与针头可拆卸地分离,用于接收血液回流。

    • Catheter-based coronary surgery is performed in a system which includes a combination of bypass of the heart, perfusion of the heart and the use of a therapeutic catheter to loosen plaque deposited in a coronary artery. Bypass is done with a bypass circuit circulating blood from the right atrium through an extracorporeal bypass unit and back through a femoral artery. Perfusion is done by passing a perfusate into the heart for retrograde flow, then drawing the perfusate out of the heart through a catheter which also serves as a guide for the therapeutic catheter. The open distal end of the guide is placed sufficiently close to the functional element at the end of the therapeutic catheter that plaque which has been loosened by the action of the therapeutic catheter is carried into the guide along with the perfusate, and hence out of the patient's body.
    • 基于导管的冠状动脉手术在包括心脏旁路,心脏灌注和使用治疗导管以松开沉积在冠状动脉中的斑块的组合的系统中进行。 旁路通过旁路回路进行,循环血液从右心房循环通过体外旁路装置并通过股动脉回流。 灌注通过将灌注液通过心脏进行逆行流动,然后通过还用作治疗导管的导管的导管从心脏中抽出灌注液。 引导件的敞开的远端放置在治疗导管末端的功能元件足够靠近的位置,该治疗导管已经被治疗导管的作用松动的斑块与灌注液一起被携带到引导件中,因此出于 病人的身体。
