    • Techniques and apparatus are described for applying alternating and/or pulsed, electrical charges to open circuitry incorporated into medical devices intended to be placed into contact with portions of the body. A catheter assembly is described which comprises a catheter tube, an exterior portion of which is circumferentially surrounded by at least two parallel elongated helical conductive elements which may be operably connected to a power source to create a open circuit to induce an antimicrobial effect in the area proximate the exterior conductive elements through oligodynamic activity. In another embodiment, an oligodynamic dressing is described which incorporates open circuitry which is presented to contact a subject wound.
    • 描述了用于将交替和/或脉冲的电荷施加到并入到旨在与身体的部分接触的医疗装置中的开放电路的技术和装置。 描述了一种导管组件,其包括导管,其外部部分由至少两个平行的细长螺旋导电元件围绕,所述至少两个平行的细长螺旋导电元件可操作地连接到电源,以产生开路以在该区域中产生抗微生物作用 靠近外部导电元件通过低能动力活动。 在另一个实施例中,描述了一种包含被呈现为接触受试者伤口的开放电路的小动物敷料。

    • A catheter assembly is described which comprises a catheter tube, an exterior portion of which is circumferentially surrounded by at least two parallel elongated helical conductive elements which may be operably connected to a first power source to create a first open circuit to induce an antimicrobial effect in the area proximate the exterior conductive elements through oligodynamic activity. The catheter assembly further comprises a hub at its proximal end having a cap containing a second power source. At least two internal conductive elements are disposed along the internal length of the hub and are operably connected to the second power source upon closure of the hub with the cap to create a second open circuit which creates an antimicrobial effect proximate the hub through oligodynamic activity.
    • 描述了一种导管组件,其包括导管管,其外部部分由至少两个平行细长的螺旋导电元件围绕,所述至少两个平行细长的螺旋导电元件可操作地连接到第一电源,以产生第一开路以诱导抗微生物效果 靠近外部导电元件的区域通过低能动力活动。 导管组件还包括其近端处的毂,其具有包含第二电源的帽。 至少两个内部导电元件沿着毂的内部长度设置,并且在与盖子封闭的情况下可操作地连接到第二电源,以产生第二开路,其通过低能动力活动产生靠近轮毂的抗微生物作用。
