    • Methods and apparatus are provided for such uses as attaching grafts of tubing (e.g., lengths of saphenous vein) between sites in a patient's body via the patient's existing arteries and veins. Grafts may be held in place during graft delivery using a partially inflated proximal balloon and a partially inflated distal balloon which frictionally engage axially spaced portions of the graft (e.g., pronged attachment rings that pierce the graft adjacent its ends). After aligning the distal balloon and distal end of the graft with the distal attachment site, the distal balloon may be further inflated to help attach the distal end of the graft to the distal attachment site (e.g., by driving the prongs of the distal attachment ring into the distal attachment site). The proximal balloon may then be inflated to similarly help attach the proximal end of the graft to the proximal attachment site. The balloons are deflated to facilitate withdrawal of the apparatus from the installed graft. The insertion instrument allows the distance between the distal and proximal balloons to be adjusted, thereby accommodating grafts of various lengths. The separation between distal and proximal balloons may be fixed or substantially fixed using a locking mechanism.
    • 提供了用于例如通过患者现有的动脉和静脉将患者体内的位置之间的管(例如,隐静脉长度)的移植物附接的方法和装置。 移植物可以在移植物输送期间使用部分充气的近端球囊和部分充气的远端球囊保持在适当位置,所述远端球囊摩擦地接合移植物的轴向间隔的部分(例如,穿过邻近其端部的移植物的插入连接环)。 在使远端球囊和远端附着部位对准移植物的远端后,远端球囊可以进一步膨胀以帮助将移植物的远端附接到远侧附接部位(例如,通过驱动远侧附接环的尖头 进入远端附件部位)。 然后可以将近端球囊充气以类似地帮助将移植物的近端附接到近端附着部位。 气囊被放气以便于将装置从装载的移植物中取出。 插入器械允许调节远端和近端气球之间的距离,从而容纳各种长度的移植物。 远端和近端球囊之间的分离可使用锁定机构固定或基本固定。
