摘要： The present invention provides a modular prosthetic valve device designed as two or more device modules that may be delivered to a body lumen unassembled and then assembled into the assembled valve device in the body at least in part using a self-assembly member at or near the site of valve implantation. The device modules may include a support structure and a valve module. The valve module may be delivered in an unassembled, folded delivery configuration, and unfolded and assembled into a working configuration via the self-assembly member. In its unassembled form, the valve module may be a single-piece leaflets substructure or a plurality of valve sections. The self-assembly member has a delivery configuration and a preset configuration, and may be triggered to revert to the preset configuration to assemble the valve module. The modular valve device may be folded in a manner not possible with current valve devices, for example, by rolling the unassembled valve module along its circumferential axis in the direction of its height, so that the diameter of the folded valve module may be equivalent to that of one rolled leaflet. This feature of the invention provides a percutaneous valve device having a smaller delivery diameter than pre-assembled valve devices. This in turn permits use of a delivery device of reduced diameter and increases the flexibility of the loaded delivery device compared to percutaneous valve devices in the art. The invention further provides a system for and method of folding and delivering such a modular valve device and assembling it using the self-assembly member, preferably in the body.
摘要翻译：本发明提供了一种设计为两个或更多个装置模块的模块化假体瓣膜装置，其可以被输送到未被组装的身体腔体，然后至少部分地使用位于或靠近该组件的自组装构件瓣膜植入部位。装置模块可以包括支撑结构和阀模块。阀模块可以以未组装的折叠输送构造递送，并且经由自组装构件展开并组装成工作构型。在其组装形式中，阀模块可以是单件式叶片子结构或多个阀部分。自组装构件具有输送配置和预设配置，并且可以被触发以恢复到预设配置以组装阀模块。模块化阀装置可以以当前阀装置不可能的方式进行折叠，例如通过沿着其周向轴线在其高度方向上滚动未组装的阀模块，使得折叠的阀模块的直径可以等于一个滚动的小叶。本发明的该特征提供了一种具有比预组装阀装置更小的输送直径的经皮瓣膜装置。这又允许使用减小直径的输送装置，并且与本领域中的经皮瓣膜装置相比增加了装载的输送装置的灵活性。本发明还提供了一种用于折叠和传送这种模块化阀装置的系统和方法，并且使用自组装构件优选地在身体中组装它。

摘要： The invention provides a device for fine adjustment of a prosthetic valve device and a method of adjusting the position of a prosthetic valve after implantation. The adjustment mechanism includes complementary structures on a valve member and device frame that cooperate to provide relative axial and/or angular motion between the valve member and device frame (and thus the native vessel). The adjustment mechanism of the invention may also include a means for selectively maintaining the relative position of the valve member and device frame. The device and method are particularly applicable for use with a modular prosthetic valve device that is assembled in the body lumen.

摘要： The invention provides a multi-component (modular) percutaneous valve device that includes a valve module having valve leaflets and a valve frame. The valve frame includes one or more, for example two, ring members and a plurality of masts. Also provided is a valve frame having specially designed pivot points at the connection between masts and first and second ring members to assist folding the valve module and minimizing delivery diameter. The valve frame may also include wire guides to facilitate combining the valve module with a support module. The masts or a ring of the valve frame may also include locking members, such as shafts for closing the valve module and securing the valve module to the support module. The support module includes corresponding locking members, such as spears that align with the shafts on the valve module for assembly and locking the valve module to the support module.

摘要： A percutaneous device including a temporary valve (104) attached to a sheath (101), the sheath (101) having an inverting section for delivery and removal thereof from a blood vessel. The sheath (101) is inverted for delivery, housing the valve between inverted layers thereof. To deploy said valve, the sheath (101) is everted to position the temporary valve (104) on an outer surface (117) thereof. The temporary valve (104) and sheath (101) are reversibly movable between inverted and deployed configurations. Upon eversion, the temporary valve (104) assumes a radially expanded canopy (106) shape having an outer diameter selected to contact the vessel wall and allow blood flow in only one direction (1, 2). The temporary valve (104) may be removed by releasing one end of the valve from the sheath (101), flattening the temporary valve (104) along the longitudinal axis of the sheath (101). Also provided is a temporary valve (104) system comprising a dilator (160) for inverting and everting the sheath (101), said dilator (160) being removably connected to the sheath (101).

In one embodiment, the device has a substantially flat valve unit and a substantially flat filter unit. In another embodiment, the device has at least one open umbrella deployed configuration. In one aspect, the device has a unitary construction with one umbrella canopy with one or more filter areas with flaps allowing unidirectional blood flow. In another aspect, the device has a valve unit and filter unit, the umbrella canopies oriented in opposite directions, and the valve unit "closes" and opens to allow blood to flow to one direction. Also provided is a temporary valve system, including a core having an inverted delivery configuration and everted deployed configuration, that may be used with or without a filter unit, and a method of deployment.
