    • An intravascular catheter that exhibits the combined features of superior flexibility, softness, radiopacity and oval/kink resistance. The catheter includes an elongate shaft having a proximal region, a distal region and a lumen extending therethrough. The proximal region of the shaft includes an inner lubricious polymer layer, a reinforcement layer and an outer layer. The reinforcement layer comprises a braid having one or more metallic members and a plurality of polymer members wherein each polymer member comprises a plurality of monofilaments, preferably formed of LCP. The polymer members of the braid provide improved flexibility and softness in addition to high burst pressure. The metallic member(s) of the braid provide improved radiopacity and oval/kink resistance. The catheter may also include a longitudinal member extending along the reinforcement layer.
    • 一种血管内导管,其具有优异的柔韧性,柔软性,不透射线性和椭圆形/扭结阻力的组合特征。 导管包括细长轴,其具有近端区域,远侧区域和延伸穿过其中的内腔。 轴的近侧区域包括内部光滑聚合物层,加强层和外层。 加强层包括具有一个或多个金属构件和多个聚合物构件的编织物,其中每个聚合物构件包括多个单丝,优选由LCP形成。 除了高爆裂压力之外,编织物的聚合物构件提供了改善的柔韧性和柔软性。 编织物的金属构件提供了改善的射线不透性和椭圆形/扭结阻力。 导管还可以包括沿加强层延伸的纵向构件。

    • A modular, on-site, wastewater treatment system removes total nitrogen, phosphorus, BOD, and TSS. A flow equalization module provides a constant flow rate to the system eliminating the adverse effects from variations in flow rate throughout the day. Treatment modules are similarly sized to provide a compact, modular system. The nitrification module is a fixed-film, flooded packed bioreactor to facilitate bioconversion of ammonia to nitrate. Aeration of the module provides the oxygen needed for the bioconversion as well prevents clogging of the film. Solids from the nitrification process are removed in a first cone-shaped settling tank. De-nitrification where nitrate is converted to nitrogen gas takes place in an anaerobic fixed-film bioreactor. Carbon-based bio-film carriers provide a carbon source for de-nitrification. A final cone-shaped settling tank separates solids from the treated wastewater. Additional modules to address removal of phosphorous or other contaminants can be added to the modular system.
    • 模块化的现场废水处理系统可以去除总氮,磷,BOD和TSS。 流量均衡模块为系统提供恒定的流量,消除了全天流量变化的不利影响。 处理模块的尺寸相似,以提供紧凑的模块化系统。 硝化模块是一种固定膜,淹没的生物反应器,用于促进氨转化为硝酸盐。 模块的曝气提供生物转化所需的氧气,同时防止膜的堵塞。 在第一锥形沉淀槽中除去来自硝化过程的固体。 在厌氧固定膜生物反应器中进行硝酸盐转化为氮气的脱硝。 碳基生物膜载体提供了用于脱硝的​​碳源。 最终的锥形沉淀池将固体与经处理的废水分开。 可以向模块化系统添加用于解决磷或其他污染物去除的附加模块。

    • A tissue ablation assembly comprises an elongate probe device, at least one ablation electrode element carried by the probe device for conveying ablation energy, and at least one magnetic element for substantially altering the path of the ablation energy conveyed by the electrode element(s). In one embodiment, the magnetic element substantially urges the ablation energy radially outward. In another embodiment, magnetic element takes the form of a ring magnet that exhibits at least four alternating magnetic poles circumferentially disposed around the probe device axis. A method of treating tissue (e.g., a tumor) is also provided. The method comprises introducing a probe device into the patient, conveying ablation energy from the probe device, and applying a magnetic field adjacent the probe device to substantially alter the path of the ablation energy, e.g., by urging the ablation energy conveyed from the probe device radially outward into the tissue to create a tissue lesion, or by urging the ablation energy longitudinally.
    • 组织消融组件包括细长的探针装置,由探针装置承载的用于传送消融能量的至少一个消融电极元件以及用于基本上改变由电极元件传送的消融能量的路径的至少一个磁性元件。 在一个实施例中,磁性元件基本上推动消融能量径向向外。 在另一个实施例中,磁性元件呈环形磁铁的形式,其呈现围绕探针器件轴线周向设置的至少四个交变磁极。 还提供了治疗组织(例如肿瘤)的方法。 该方法包括将探针装置引入患者体内,从探针装置输送消融能量,以及施加邻近探针装置的磁场,以基本上改变消融能量的路径,例如通过促使从探针装置传送的消融能量 径向向外进入组织以产生组织损伤,或通过纵向推动消融能量。
