    • Devices and methods for placing a conduit (10) in fluid communication with a target vessel (TV) to communicate the target vessel (TV) with a source of blood. A conduit (10) is coupled to the target vessel (TV) by first (14) and second (16) securing components that compress or sandwich the vessel wall. The conduit (10) can be preshaped to assume a desired orientation when in an unbiased state, for example, to allow the conduit (10) to be deformed during delivery and then regain its desired orientation once deployed. The first (14) and second (16) securing components may be any shape but are preferably elongated in the direction of the vessel axis, e.g., elliptical or rectangular, such that a minimum amount of material is present at the outlet to closely approximate the cross-sectional area of the native target vessel. The securing components (14, 16) do not significantly occlude the target vessel lumen, may be secured to the vessel wall in non-penetrating fashion, and provides a fluid-tight seal around the attachment site. The conduit (10) may comprise tissue, synthetic material, etc., and one or both securing components may be constructed or provided with means for attaching an outologous vessel.
    • 用于放置导管(10)与目标血管(TV)流体连通以将目标血管(TV)与血源通信的装置和方法。 导管(10)通过第一(14)和第二(16)固定部件来紧固到目标血管(TV),压缩或夹住血管壁。 当处于无偏压状态时,导管(10)可以预成形为呈现期望的取向,例如允许导管(10)在输送期间变形,然后一旦展开就恢复其期望的取向。 第一(14)和第二(16)固定部件可以是任何形状,但是优选地在容器轴线的方向上是细长的,例如椭圆形或矩形的,使得在出口处存在最小量的材料以紧密接近 天然目标血管的横截面积。 固定部件(14,16)不会明显地堵塞目标血管腔,可以非穿透方式固定到血管壁上,并且在附着部位周围提供流体密封的密封。 导管(10)可以包括组织,合成材料等,并且一个或两个固定部件可以被构造或设置有用于附接排便器的装置。
