    • Tissue shaping methods and devices are provided for reinforcing and/or remodeling heart valves. In certain embodiments, magnetic tissue shaping devices are implanted in tissue adjacent heart valve leaflets. The devices are mutually attractive or repulsive so as to remodel the heart tissue and improve heart valve function. In certain other embodiments, one or more tissue shaping devices including shape memory material are implanted in a patient's body within or on tissue adjacent a heart valve leaflet. The shape memory material can be activated within the patient in a less invasive or non-invasive manner, such as by applying energy percutaneously or external to the patient's body. The shape memory tissue shaping devices are implanted in a first configuration and then activated to remember a second configuration that displaces tissue so as to remodel the heart valve geometry and improve heart valve function. In certain other embodiments, a brace is crimped to the base of a heart valve leaflet to support the leaflet and improve valve closure.
    • 提供组织成形方法和装置用于加强和/或改造心脏瓣膜。 在某些实施例中,将磁组织成形装置植入在心脏瓣膜小叶附近的组织中。 这些装置是相互吸引或排斥的,以便改造心脏组织并改善心脏瓣膜功能。 在某些其他实施例中,包括形状记忆材料的一个或多个组织成形装置植入在心脏瓣膜附近的组织内或组织附近的患者体内。 形状记忆材料可以以较少侵入性或非侵入性方式在患者体内被激活,例如通过经皮或外部施加能量到患者身体。 形状记忆组织成形装置以第一配置植入,然后被激活以记住置换组织的第二配置,以便改造心脏瓣膜几何形状并改善心脏瓣膜功能。 在某些其他实施例中,支架卷曲到心脏瓣膜小叶的底部以支撑小叶并改善瓣膜关闭。

    • Systems, methods and devices are provided for treating heart failure patients suffering from various levels of heart dilation. Such heart dilation is treated by reshaping the heart anatomy with the use of shape memory elements. Such reshaping changes the geometry of portions of the heart, particularly the right or left ventricles, to increase contractibility of the ventricles thereby increasing the stroke volume which in turn increases the cardiac output of the heart. The shape memory elements have an original shape and at least one memory shape. The elements are implanted within the heart tissue or attached externally and/or internally to a surface of the heart when in the original shape. The elements are then activated to transition from the original shape to one of the at least one memory shapes. Transitioning of the elements cause the associated heart tissue areas to readjust position, such as to decrease the width of the ventricles. Such repositioning is maintained over time by the elements, allowing the damaging effects of heart dilation to slow in progression or reverse.
    • 提供了用于治疗患有各种心脏扩张水平的心力衰竭患者的系统,方法和装置。 通过使用形状记忆元件重建心脏解剖结构来治疗这种心脏扩张。 这种重塑改变了心脏的部分的几何形状,特别是右心室或左心室,以增加心室的收缩性,从而增加了行程体积,从而增加了心脏的心输出量。 形状记忆元件具有原始形状和至少一种存储器形状。 当原始形状时,将元件植入心脏组织内或外部和/或内部附着到心脏的表面。 元件然后被激活以从原始形状转换到至少一个存储器形状之一。 元件的过渡导致相关的心脏组织区域重新调整位置,例如减小心室的宽度。 这种重新定位由元素随时间推移而维持,从而允许心脏扩张的破坏性影响进展缓慢或逆转。

    • A hinged socket wrench having an offset shank (20) with a first end (22) and a second end (24). Attached to the first end (22) is a clevis (28) which receives a 180-degree drive head held by a hinge pin (40). The drive head consists of either a square drive head (30) or a ratchet drive head (31). To the second end is attached a rotatable handle (58), which rotates the wrench upon reciprocation of the handle (58). A second embodiment of the hinged socket wrench includes a second clevis (28) that is added to the second end (24) of the offset shank. The second clevis (28) adds further combinations of angular displacement of the handle (58). Thus, increasing the value of the wrench as a tool and also its productivenss in difficult work areas. Five configurations of the hinge pin (40) provide additional surface interface with both the hinge pin and the handle yoke improving the structural integrity and prolonging tool life.
    • 具有带有第一端(22)和第二端(24)的偏移柄(20)的铰接套筒扳手。 连接到第一端(22)的是一个U形夹(28),其接收由铰链销(40)保持的180度的驱动头。 驱动头由方形驱动头(30)或棘轮驱动头(31)组成。 在第二端附接有可旋转手柄(58),该手柄在手柄(58)往复运动时旋转扳手。 铰链式套筒扳手的第二实施例包括被附加到偏置柄的第二端(24)的第二U形夹(28)。 第二U形夹(28)增加了手柄(58)的角位移的进一步组合。 因此,增加扳手的价值作为工具,并在艰苦的工作领域生产。 铰链销(40)的五种构造为铰链销和手柄轭提供了额外的表面接口,提高了结构的完整性并延长了工具的使用寿命。

    • A breather device connects to a vessel. The breather device inlets air to the vessel and filters the air upon inlet via a filter media, and exhausts air from the vessel. The vessel has a pressure that may vary and a low pressure threshold and a high pressure threshold. The breather device includes a housing, a cartridge removable from the housing for containing the filter media, an inlet check valve to the housing, the inlet check valve is selectively biased to prevent flows therethrough unless the pressure in the vessel falls below the low pressure threshold, an outlet check valve from the housing, the outlet check valve is selectively biased to prevent exhaust therethrough unless the pressure in the vessel exceeds the high pressure threshold, and a pressure gauge connected to the housing for measuring internal pressure in the vessel. The breather device can additionally include seals and/or an internal check valve between the filter media and the vessel. The internal check valve, if present, prevents exhaust air of the vessel from contacting the filter media.
