    • A filar includes an inner conductive core that is formed of a low-resistivity material such as silver having a resistivity of less than 20μΩ per centimeter. A conductive coil is provided around the core to form a filar. This coil is formed of a biocompatible alloy or super alloy having an ultimate tensile strength (UTS) of between 150 kilo pounds per square inch (ksi) and 280 ksi at room temperature. Examples of such alloys include CoCrMo, CoFeCrMo, and CoFeNiCrMo. In one specific embodiment, the alloy is MP35N (CoNiCrMo), which may be low-titanium ("low-ti") MP35N. One or more such filars may be included within a wire. This wire may be carried by an implantable medical apparatus such as a lead, lead extension, or catheter. The wire may electrically couple elements such as connector electrodes to conducting electrodes or sensors.
    • 丝状物包括由诸如银的低电阻率材料形成的内导电芯,其电阻率小于每厘米20μO。 在芯周围设置导电线圈以形成丝状体。 该线圈由在室温下具有150千磅/平方英寸(ksi)和280ksi之间的极限拉伸强度(UTS)的生物相容性合金或超级合金形成。 这种合金的实例包括CoCrMo,CoFeCrMo和CoFeNiCrMo。 在一个具体实施方案中,合金是MP35N(CoNiCrMo),其可以是低钛(“低钛”)MP35N。 一根或多根这样的丝状物可以包括在线内。 该线可以由诸如铅,引线延伸或导管的可植入医疗设备携带。 导线可以将诸如连接器电极的元件电耦合到导电电极或传感器。

    • A region of a borehole with one or more openings to be sealed off, such as one or more fractures, voids, and or pores, may or may not be sealed off around a tubular string with a borehole seal such as a packer or plug. A carrying fluid may be utilized to transport a filtration material into the opening to create a bridge, which at least partially seals the opening, but still provides a flow path that permits fluid flow therethrough. A solid material and/or settable material may then utilize the fluid flow subsequently or be simultaneously spotted with or behind the filtration material to thereby form compositions which effectively seals off the flow path into the one or more openings.
    • 具有一个或多个要被密封的开口的井眼的区域,例如一个或多个裂缝,空隙和/或孔隙,可以围绕具有诸如封隔器或塞子的钻孔密封件的管状管柱密封或不被密封。 可以使用携带流体将过滤材料输送到开口中以产生至少部分地密封开口的桥,但仍提供允许流体流过其中的流动路径。 然后,固体材料和/或可固化材料可随后利用流体流,或者与过滤材料之间或之后同时点样,从而形成有效地密封流入一个或多个开口的流动路径的组合物。
