    • 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 apparatus and method for exchanging a first intravascular catheter of the over-the-wire type, such as an angioplasty balloon dilation catheter, with a second intravascular catheter of the over-the-wire type while leaving a guide wire in position in a desired vascular site. The apparatus is used in conjunction with a conventional guide catheter, a guide wire, and an interventional catheter that can be positioned intravascularly through a lumen of the guide catheter over the guide wire and past a distal end of the guide catheter to a desired vascular site. The apparatus includes an elongate shaft that can be removably positioned in the lumen of the guide catheter and has an actuation capability therein. A trapping member is located at a distal portion of the elongate shaft for releasably fixing the relative position of the guide wire with respect to the guide catheter. The fixing and releasing of the trapping member is effected by the actuation capability from outside the body of the patient so that a first interventional catheter can be exchanged for a second interventional catheter by trapping the guide wire position relative to the guide catheter while withdrawing the first interventional device and replacing it with another.
    • 一种用于与线上类型的第二血管内导管(例如血管成形术球囊扩张导管)交换诸如血管成形术球囊扩张导管的第一血管内导管的装置和方法,同时将引导线留在期望的位置 血管部位。 该装置与传统的导向导管,导丝和介入导管一起使用,其可以通过引导导管的导管血管内定位并且经过引导导管的远端定位到期望的血管部位 。 该装置包括细长轴,其可移除地定位在引导导管的内腔中并且在其中具有致动能力。 捕获构件位于细长轴的远侧部分,用于可释放地固定导丝相对于导向导管的相对位置。 捕获构件的固定和释放通过来自患者体外的致动能力来实现,使得可以通过相对于引导导管捕获引导线位置而将第一介入导管更换为第二介入导管,同时撤回第一介入导管 介入装置,并用另一种装置代替。
