  • Publication number: 20150207484
    Abstract: A composite RF current attenuator for a medical lead includes a conductor having a distal electrode contactable to biological cells, a bandstop filter in series with the lead conductor for attenuating RF currents flow through the lead conductor at a selected center frequency or across a range of frequencies about the center frequency, and a lowpass filter in series with the bandstop filter and forming a portion of the lead conductor. The bandstop filter has a capacitance in parallel with a first inductance. In a preferred form, the lowpass filter includes a second inductance in series with the bandstop filter, wherein the values of capacitance and inductances for the composite RF current attenuator are selected such that it attenuates MRI-induced RF current flow in an MRI environment.

  • Patent number: 7483260
    Abstract: A capacitor a casing of first and second casing members, a feedthrough electrically insulated from the casing and extending there from, first and second anodes electrically connected to each other within the casing, a cathode, and an electrolyte is described. The first anode is electrically connected in parallel to the second anode by a first anode wire having opposite ends contacting the respective first and second anodes. A feedthrough wire extending outside the casing and electrically isolated there from is electrically connected to the first anode wire intermediate the first and second anodes. The cathode is disposed between the first and second anodes.

  • Patent number: 6850405
    Abstract: New designs that provide two anodes and their associated feedthroughs incorporated into one capacitor are described. The feedthrough wires can be in their own glass-to-metal seal or, they can be combined into one glass-to-metal seal as long as they are electrically insulated from each other. One embodiment has the anode feedthroughs left unconnected, while in other embodiments; they are joined externally of the capacitor casing. Several interconnect designs are described.

  • Patent number: 5536279
    Abstract: In an alkali metal-halogen or oxyhalide electrochemical cell wherein an alkali metal anode, preferably lithium, has a surface in operative contact with a halogen-containing or oxyhalide cathode/electrolyte including a solvent if necessary, an electrode covering, preferably applied on the anode surface comprising a non-fabric, continuous and solid film of substrate material having a uniform unit weight, is described. The substrate material is perforated to provide for ion flow therethrough and coated with organic electron donor material, or other suitable coating material. The film substrate material preferably comprises a mechanically perforated synthetic polyester film material, and the film is prepared by contacting with a solution of the organic material and solvent followed by drying. The resulting coated film is flexible and is applied to the operative surface of the electrode thereby covering the same, preferably adhered to the surface by pressing.
