    • Disclosed are esophageal anti-reflux valve prostheses, and tools and procedures for peroral implantation and extraction of the prostheses. The prostheses disclosed have a semipermeable membrane to allow retrograde passage of gas, magnets disposed at a distal end of the sleeve to facilitate closure, and an outwardly bendable array of spikes that are longitudinally aligned for peroral insertion and lockable into a radially outwardly deployed configuration to keep the prosthesis from dislocating after implantation. The implantation tool has inner and outer concentric tubes, the inner tube releasably threadably connected to the prosthesis, the outer tube reverse threaded with the inner tube to advance a distal headpiece to engage, deploy and lock the spikes into the deployed configuration. A vacuum assist can be used to help impact the lumen wall on the spikes. The extraction tool is similar to the implantation tool with an inner tube for threadably engaging the prosthesis, an outer tube with a distal crown with a plurality of shoes to unseat and unlock the spikes, and an overtube shield to receive the spikes and facilitate extraction of the prosthesis.
    • 公开了食管抗回流瓣膜假体,以及用于口腔植入和提取假体的工具和程序。 公开的假体具有半透膜,以允许气体的逆行通过,设置在套筒远端的磁体以便于闭合,以及可向外弯曲的尖峰阵列,其纵向对准以便口腔插入并可锁定到径向向外展开的构型中 保持假体在植入后脱位。 植入工具具有内部和外部同心管,内部管可释放地螺纹连接到假体,外部管与内部管螺纹连接,以推进远端头部以接合,部署和锁定钉入展开构型。 可以使用真空辅助来帮助撞击钉上的管腔壁。 提取工具类似于植入工具,其具有用于螺纹地接合假体的内管,具有多个鞋子的远端冠的外管,用于拆卸和解锁钉,以及外套管护罩以接收钉并促进提取 假体。

    • Liquid filter assemblies including an upper sample reservoir, a sample filter and a lower storage bottle are supported by a vacuum base. The base has a vacuum inlet port and, for connection to the liquid filter assembly, a vacuum outlet port. A vacuum is provided through the base to below the sample filter to draw sample liquid through the sample filter into the storage bottle. The base may include an auxiliary vacuum outlet port for connection with additional devices. The bases may be connected from one to another through auxiliary vacuum outlets and the vacuum inlets to make a chain of liquid filter assemblies supplied from one vacuum source. Alternatively, one base may include multiple vacuum outlet ports so that it may support and supply vacuum to a plurality of liquid filter assemblies.
    • 包括上样品容器,样品过滤器和下储存瓶的液体过滤器组件由真空底座支撑。 基座具有真空入口,并且用于连接到液体过滤器组件的真空出口。 通过底部提供真空至样品过滤器下方,将样品液体通过样品过滤器吸入储存瓶中。 基座可以包括用于与附加装置连接的辅助真空出口。 底座可以通过辅助真空出口和真空入口从一个连接到另一个,以形成一个从一个真空源供应的液体过滤器组件链。 或者,一个基座可以包括多个真空出口端口,使得其可以支撑并提供多个液体过滤器组件的真空。
