    • A wrap (20) for securing about a blood vessel (36) by encasing a section of the vessel. The wrap (20) being of thin flexible construction having two ends (22, 24) and two sides (26, 28). The wrap (20) is more elastic or stretchable at, near, or along at least some of its sides (22, 24) compared to at, near, or along its centre, to provide strain relief from wrapped to unwrapped aorta. The wrap (20) is not inelastic, so that loss of aortic compliance is minimised or enhanced. The wrap (20) is adapted to apply, in use, less compressive force at, near, or along at least some of its sides (22, 24) compared to at, near, or along its centre.
    • 通过包裹血管的一部分来固定血管(36)的包裹物(20)。 包裹物(20)具有薄的柔性结构,具有两个端部(22,24)和两个侧边(26,28)。 与其中心处,中心附近或沿其中心相比,包裹物(20)在其侧面(22,24)中的至少一些侧面(22,24)处,附近或沿着其中心更有弹性或可拉伸,以从缠绕的至未包裹的主动脉提供应力消除。 包裹物(20)不是非弹性的,因此主动脉顺应性的损失被最小化或增强。 与其在其中心处,中间或附近相比,包裹(20)适于在使用中在其至少一些侧面(22,24)处,附近或沿着其至少一些侧面施加较小的压缩力。

    • A heart assist device in which an inflatable balloon or chamber is held against an outside surface of a curved arterial vessel by a wrap (20) formed from a flexible sheet-like material. The wrap (20) having a first end portion (22), a second end portion (30) and an intermediate portion (26) connecting together the first and second end portions (22, 30). The intermediate portion (26) comprising at least three separate elongate sections (26a-c) arranged in side by side array each connected at each end to a respective one of the end portions (22, 30) of the wrap (20). The improvement in that the laterally outer ones (26a,b) of the elongate sections are longer than the central one (26c) of them. As a result, if the wrap (20) was laid on a planar surface, the central (26c) one of the elongate sections would lie substantially in that plane and the laterally outer ones (26a,b) of the elongate sections would, intermediate their ends, project above that plane.

    • An actuator (10) for a heart assist device. The actuator (10) includes an inflatable balloon (12) and a shroud or wrap (14). The inflatable balloon (12) has a first body portion (22), a second body portion (26) and a flexure regionjoining (24) the first (22) and second (26) body portions. The shroud or wrap, (14) is positioned adjacent the first body portion (24) and has a peripheral extent at least equal to, the peripheral extent of the balloon flexure region (24). The balloon (12) and the shroud or wrap (14) are shaped such that the shroud or wrap (14) restrains a part of the balloon first body portion (22) at or near the flexure region (24) against displacement towards the shroud or wrap (outward displacement) past a predetennined limit but allows unrestrained displacement away from the shroud or wrap (inward displacement).
    • 一种用于心脏辅助装置的致动器(10)。 致动器(10)包括可充气气囊(12)和护罩或包裹物(14)。 可充气气囊(12)具有第一主体部分(22),第二主体部分(26)和与第一主体部分(22)和第二主体部分(24)连接的弯曲部分。 护罩或包裹物(14)定位成邻近第一主体部分(24),并且具有至少等于球囊挠曲区域(24)的周边范围的周边程度。 气囊(12)和护罩或包裹物(14)成形为使得护罩或包裹物(14)在弯曲区域(24)处或附近限制球囊第一主体部分(22)的一部分,以防止朝向护罩 或包裹(向外移位)超过预定限制,但允许远离护罩或包裹(向内移位)的无限制位移。
