    • A perfusion catheter for insertion into a body conduit, especially an artery. The catheter comprises a shaft (5) having at least two lumens for delivery of fluid inflation medias and an array (1) formed of a plurality of radially disposed inflatable balloons (3) disposed in a cylindrical array around the shaft (5), each of the balloons (3) sharing a common wall (3a) with adjacent balloons (3). The balloons (3) are inflated by an array (1) of channels (11) and separated from each other by a web (19). There is at least one opening (17) between two adjacent channels (11) to allow the flow of fluids into the array (1). An internal chamber (31) is formed inside the array (1) by the movement of a wall (30) over the axis of the catheter whereby to enable a substantial increase of inflation forces against the body conduit in which the catheter is disposed.
    • 用于插入身体导管,特别是动脉的灌注导管。 导管包括具有用于输送流体充气介质的至少两个流明的轴(5)和由围绕轴(5)设置在圆柱形阵列中的多个径向设置的可充气气囊(3)形成的阵列(1),每个 (3)与相邻的气球(3)共享公共壁(3a)。 气球(3)由通道(11)的阵列(1)充气,并通过腹板(19)彼此分离。 在两个相邻通道(11)之间有至少一个开口(17),以允许流体流入阵列(1)。 通过壁(30)在导管的轴线上的运动,在阵列(1)内部形成内部腔室(31),从而能够大大增加针对其中设置导管的身体导管的充气力。

    • A book cover structure of the type having front and back covers for binding sheets therebetween. A backbone area is joined with the front and back covers. The backbone area is provided with spaced parallel strips of hot melt adhesive with transversely extending bridge means of hot melt adhesive extending therebetween the width of the backbone area. Spaced score lines are positioned between the parallel strips under the bridges in parallel relation relative to the strips to enable the user to flex the binding along selectable score lines relative to the backbone area. The bridge means of hot melt adhesive and the strips comprise means for holding sheets in bound engagement with the backbone area. The bridge means of hot melt adhesive extend across the score lines and thus provide continuity of adhesive on opposite sides of and across the score lines. At least one of the covers may have a second set of spaced parallel score lines adjacent an outer edge remote from the backbone area and disposed in parallel relation relative to the strips. At least one of the score lines in the second set may be folded leaving the outer edge in lapped relation relative to the associated cover, the score lines in the second set being selectably usable depending on the number of the sheets to be bound.
    • 这种类型的书盖结构具有用于在其间粘合片材的前盖和后盖。 骨干区域与前盖和后盖相连。 骨架区域设置有间隔开的热熔粘合剂条,其横向延伸的热熔粘合剂的桥接装置在其间在骨架区域的宽度之间延伸。 间隔刻痕线相对于条带以平行关系位于桥下的平行条之间,以使用户能够沿着相对于骨架区域的可选刻痕线弯曲绑定。 热熔粘合剂的桥接装置,并且条带包括用于保持与骨架区域结合接合的片材的装置。 热熔粘合剂的桥接装置延伸穿过刻痕线,从而在刻痕线的相对侧和横过刻痕线提供粘合剂的连续性。 覆盖物中的至少一个可以具有与远离骨架区域的外边缘相邻并且相对于条带平行关系设置的第二组间隔开的平行划线。 第二组中的评分线中的至少一个可以折叠,离开相关联的盖的重叠关系的外边缘,根据要绑定的片的数量,第二组中的刻痕线可选地可用。
