    摘要： A guidewire suited for inserting both diagnostic and therapeutic catheters. The guidewire has an initial uniform diameter segment that is coated with Telfon along a majority of its length. This core station tapers along a uniform portion to a second constant diameter segment surrounded by a flexible spring tip. The core again tapers in a region where the flexible spring separates from the core. The core is then flattened to increase flexibility within the flexible spring and the flattened core and spring are brazed together at a extreme distal tip portion to form a hemispherical distal guidewire tip.

    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： According to the invention there is provided an intravascular catheter comprising an elongated flexible jacket having opposed proximal and distal ends and a central passageway extending between and interconnecting the ends. A rotating working head is located at the distal end of the jacket. A flexible drive cable extends through the passageway of the jacket, having a driving end operatively connected to the working head for rotating it, and a driven end operatively connected to a high-speed motor. The working head is rotatably mounted in a bearing sleeve which is further attached to the catheter jacket. The working head is actuated, by a actuator which adjust the a pair of tip portions from an at least initial retracted position with a first effective working diameter to an extended position with a second effective working diameter greater than the first effective diameter. Centrifugal forces generated by rotation of the cable cause the tip portions to assume the greater effective working diameter.

    摘要： An inflation device in the form of a syringe assembly for pressurization and depressurization of a ballon catheter includes a manually actuated lever used to disengae a half nut from controlled threaded advancement of a threaded rod which moves a piston. The threaded engagement between the half nut and the rod is such that about one half of the circumference of the rod is engaged, and disengagement movement of the half nut from the rod occurs transversely to the longitudinal axis of the rod.

    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.
