    • An apparatus and method is provided for dispensing coil emboli one at a time in a controlled and reliable manner during surgery to embolize several blood vessels or the like in a body. The apparatus includes a magazine that is movable within a dispenser housing to position each of the embolus cartridges contained in the magazine one at a time at a dispensing station on command. A stream of pressurized fluid is injected or a guide wire is inserted into the embolus cartridge held in the dispensing station to dislodge an embolus contained therein and discharge it into an embolus-delivery catheter coupled to the dispenser housing. Afterwards, the magazine is moved within the dispenser housing to remove the just-emptied embolus cartridge from the dispensing station and load a fresh embolus cartridge into the dispensing station.
    • 提供了一种装置和方法,用于在手术期间以可控和可靠的方式一次一个地分配线栓,以将几个血管等栓塞在体内。 该装置包括可在分配器壳体内移动的盒子,以便在命令的分配站处一次一个地将容纳在盒子中的每个栓塞盒定位。 注射加压流体流,或将引导线插入到保持在分配站中的栓塞盒中,以移除其中容纳的栓塞并将其排出到与分配器壳体相连的栓塞输送导管中。 之后,盒子在分配器壳体内移动,以便从分配站移除刚刚清空的栓塞盒,并将新鲜的栓塞盒装入分配站。

    • A method for advancing a working instrument through the vascular system of a patient, the method comprising the steps of: advancing a facilitating catheter assembly within the vascular system of a patient, wherein the facilitating catheter assembly is formed out of a implantable graft material; and advancing the working instrument through the facilitating catheter assembly. A facilitating catheter assembly for use in for advancing a working instrument through the vascular system of a patient, the facilitating catheter assembly comprising a facilitating sheath and a companion sheath, the facilitating sheath being disposed within the companion sheath, the companion sheath including means for opening the companion sheath so as to release the facilitating sheath, and the facilitating sheath being formed out of implantable graft material. A method for advancing a working instrument through the vascular system of a patient, the method comprising the steps of: advancing a facilitating catheter assembly within the vascular system of a patient, wherein the facilitating catheter assembly is constructed so as to (i) have a first diameter which is less than the diameter of the working instrument, and (ii) be capable of expanding to a second diameter which is at least as large as the diameter of the working insturment; and advancing the working instrument through the facilitating catheter assembly. A facilitating catheter assembly for use in advancing a working instrument through the vascular system of a patient, the facilitating catheter assembly being constructed so as to (i) have a first diameter which is less than the diameter of the working instrument, and (ii) be capable of expanding to a second diameter which is at least as large as the diameter of the working instrument.
