    • This invention relates to apparatus and methods for use in sealing a vascular puncture site and to apparatus and methods for properly locating and deploying a sealing device. The locating apparatus comprises a lumen which extends from an opening in the distal region of the apparatus but located proximally of the sealing device, which lumen extends to another opening in the proximal region of the device. When the distal opening is in communication with blood in a blood vessel, blood flow through the lumen and out of the proximal opening signifies such location to the user. When the sealing device is withdrawn such that the sealing device is deployed such that it blocks the blood flow into the distal port, the user will know the location of the sealing device. In a preferred embodiment, the sealing device is then withdrawn proximally a predetermined distance to assure that no part of the sealing device extends into the blood vessel lumen. The sealing device is then detached from the delivery device.
    • 本发明涉及用于密封血管穿刺部位的装置和方法以及用于适当定位和展开密封装置的装置和方法。 定位装置包括从设备的远侧区域中的开口延伸但位于密封装置的近侧的内腔,该内腔延伸到装置的近侧区域中的另一个开口。 当远端开口与血管中的血液连通时,血流通过内腔并离开近端开口表示使用者的这种位置。 当密封装置被抽出时,使得密封装置被展开,使得它阻止进入远端口的血流,使用者将知道密封装置的位置。 在优选实施例中,然后将密封装置向近侧撤回预定距离,以确保密封装置的任何部分不延伸进入血管内腔。 然后将密封装置从输送装置分离。

    • A minimally invasive technique for harvesting saphenous veins and the like for use as autografts in coronary artery bypass grafting surgery include a microsurgical instrument adapted to be demountably secured to the distal end of an endoscope. The instrument is inserted through an entry incision in the patient's skin, at the end of the endoscope which is used by a surgeon to advance the instrument along the saphenous vein, using the vein as a guide for the instrument. The instrument is tapered to provide initial separation of surrounding tissues from the vein, and cutting means supported by the instrument and viewed via the endoscope allow dissection of all tissues and side branch vessels from the saphenous vein. The instrument further provides a protective hood which prevents tissues or skin from blocking the endoscope. The desired length of saphenous vein is transected and is extracted via the entry incision. The technique minimizes trauma to the patient and to the saphenous vein graft.
    • 在冠状动脉旁路移植手术中收获用作自体移植物的隐静脉等的微创技术包括适于可拆卸地固定到内窥镜的远端的显微外科器械。 仪器通过外科医生使用的内窥镜末端穿过患者皮肤中的入口切口插入,使用静脉作为仪器的引导件,沿着隐静脉推进仪器。 仪器是锥形的,以提供周围组织与静脉的初始分离,以及由仪器支撑并通过内窥镜观察的切割装置允许从隐静脉解剖所有组织和侧分支血管。 该仪器还提供防止组织或皮肤阻塞内窥镜的保护罩。 所需的隐静脉长度被切断,并通过入口切口提取。 该技术最大限度地减少对患者和隐静脉移植物的创伤。
