    • A drug delivery catheter which may be inserted into a vessel, such as a blood vessel is disclosed. The drug delivery catheter comprises any elongated tubular member which has a proximal end and a distal end. A drug lumen which provides a communication path for fluid is provided in the elongated tubular member for delivering a fluid, such as the drug to be administered. An inflatable balloon assembly is provided at the distal end of the elongated tubular member. The balloon assembly includes apertures which communicate with the drug lumen. The balloon assembly comprises a tubular balloon which is helically wound through the elongated tubular member and a sheath. The sheath is attached to the helically wound tubular balloon such that when the balloon member is uninflated, the first fluid in the vessel flows around the balloon assembly and such that when the balloon member is inflated, sections of the helically wound balloon contact the vessel wall to form a containment pocket between the vessel wall, the contacting sections of the balloon and the sheath. The apertures are provided in the containment pocket. An inflatable lumen is defined through the interior of the helically wound balloon and the sheath to allow perfusion of the first fluid.
    • 公开了一种可插入容器(如血管)中的药物输送导管。 药物递送导管包括具有近端和远端的任何细长管状构件。 提供用于流体的连通路径的药物腔室设置在细长管状构件中,用于输送流体,例如待施用的药物。 在细长管状构件的远端处设置可充气气囊组件。 气囊组件包括与药物腔连通的孔。 球囊组件包括通过细长管状构件和护套螺旋缠绕的管状球囊。 护套附接到螺旋形缠绕的管状气囊,使得当球囊构件未膨胀时,容器中的第一流体围绕球囊组件流动,使得当球囊构件膨胀时,螺旋形卷绕的球囊的部分接触血管壁 以在容器壁,球囊和护套的接触部分之间形成容纳袋。 孔口设置在容纳口袋中。 通过螺旋缠绕气囊和护套的内部限定可充气腔,以允许第一流体的灌注。

    • An inflation device includes a syringe forming a cylindrical chamber containing a plunger carrying a stopper or piston arrangement. The chamber is designed to contain an inflation fluid and is in fluid communication with the lumen of a balloon catheter. Movement of the plunger within the chamber will increase or decrease the pressure of the fluid within the chamber and lumen, thereby inflating or deflating the balloon at the distal end of the catheter. A pressure sensor is mounted to the housing in fluid communication with the lumen and is electrically connected to a battery-operated transmitter. The transmitter broadcasts signals representing pressure within the lumen and balloon to a remote receiver. The receiver includes a microprocessor containing a clock and operable to display time and pressure data. A flexible insulator strip is interposed between the battery and the transmitter circuit to prevent operation of the transmitter until desired by the cardiologist. The housing of the inflation device may be opened to remove the batteries for separate disposal and to render the circuit inoperative to prevent reuse. A look-up table associated with the microprocessor permits display of balloon diameter during the procedure.
    • 膨胀装置包括一个注射器,该注射器形成一个圆筒形腔室,该圆柱形腔室包含一个承载塞子或 腔室被设计成容纳充气流体并且与球囊导管的内腔流体连通。 柱塞在腔室内的运动将增加或减小腔室和腔内的流体的压力,从而在导管的远端处膨胀或放气气囊。 压力传感器安装到外壳上,与腔体流体连通,并与电池供电的变送器电连接。 发射机将表示内腔和气球内的压力的信号广播到远程接收器。 接收机包括一个包含时钟并可操作以显示时间和压力数据的微处理器。 在电池和发射器电路之间插入柔性绝缘体条,以防止发射器的操作,直到心脏病专家期望。 可以打开充气装置的壳体以移除电池以进行单独处理,并使电路不起作用以防再次使用。 与微处理器相关联的查找表允许在该过程期间显示气球直径。
