摘要： The controlled radiopaque guidewire comprises: an elongate central core wire having a reduced in diameter distal end portion; a rounded tip member having a back side to which is connected a distal end of the core wire; a first coiled spring wire having a proximal end fixed to the core wire in a proximal area thereof and a distal end fixed to the back side of the tip member; the coils of the first coiled spring wire being stretched or spaced in a distal end portion thereof; a second coiled spring wire having a proximal end fixed to the core wire and coiling outward therefrom to and between the spaced apart coils in the first coiled spring wire in the distal end portion of the first coiled spring wire and interleaved therebetween; a distal end of the second coiled spring wire being fixed to the back side of the tip member; the proximal end of the second coiled spring wire being spaced inwardly of and not in connection with coils of the first coiled spring wire; and the second coiled spring wire being more radiopaque than the first coiled spring wire.

摘要： The method for closing and sealing the opening of a wall of a container includes the steps of: providing the opening with a counterbore; inserting a first plug member into said opening in a fluid tight manner to establish a first seal; inserting a second plug member into said counterbore and above said first plug member and said opening; and fixing and sealing said second plug member to said wall around said counterbore so that a fluid tight second seal is formed between said second plug member and said wall thereby to provide a double seal for preventing leakage of fluid material from said container through said opening.The fluid tight closure assembly is adapted to provide a fluid tight closure for closing and sealing the opening in the wall of the container having fluid material therein. The closure assembly includes a first plug member which is inserted into the opening in the wall of the container in a fluid tight manner to establish a first seal, the opening being provided with a counterbore. The plug assembly further includes a second plug member which is adapted to be inserted into the counterbore above the first plug member and the opening. The second plug member is permanently fixed to the wall around the counterbore in a fluid tight manner so that a fluid tight second seal is formed between the second plug member and the wall thereby to provide a double seal for preventing leakage of fluid material from the container through the opening.

摘要翻译： 关闭和密封容器壁的开口的方法包括以下步骤：向开口提供沉孔; 以流体密封的方式将第一塞子构件插入所述开口中以建立第一密封; 将第二塞子构件插入所述沉孔中，并在所述第一塞构件和所述开口之上; 以及将所述第二塞构件固定和密封到围绕所述沉孔的所述壁上，使得在所述第二塞构件和所述壁之间形成流体密封的第二密封，从而提供双重密封，以防止流体材料从所述容器穿过所述开口泄漏。 流体密封闭合组件适于提供流体密封的封闭件，用于封闭和密封容器壁上的开口，其中具有流体材料。 闭合组件包括第一插塞构件，其以流体密封的方式插入容器的壁中的开口中以建立第一密封，该开口设置有沉孔。 插塞组件还包括第二插塞构件，其适于插入第一插塞构件和开口上方的沉孔中。 第二塞子构件以流体密封的方式永久地固定到沉孔周围的壁上，使得在第二塞子构件和壁之间形成流体密封的第二密封，从而提供双重密封，以防止流体材料从容器泄漏 通过开放。

摘要： A feedthrough is provided for mounting in and electrically insulating a conductive wire from the casing of a device such as a battery cell for a cardiac pacer. The feedthrough is a non-glass member at least a portion of which was cured in situ and formed to a shape and size generally complementary to the shape and size of the casing opening through which it is mounted and to the shape and size of the conductive wire that it mounts.
