General Specifications

The LMA with the Flexible Output Cable has been designed specifically for chronic applications. The fine leads which extend from the Polyimide shank are coiled together and coated with a silicon elastomer, allowing the shank to virtually float in the brain. You will need to specify the number of shanks, (S).

Any number of channels in between will use the larger diameter tubing. For example, a 12 channel LMA with 12.5um contact sites will use a 0.018" OD tubing.

  • a = Length of polyimide tube (15 mm max. for 12.5 µm wire)
  • b = Length of Stainless or Microfill Tube.
  • c = Electrode size (determined by selection of wire diameter).
  • d = Distance between contacts.
  • n = Number of recording sites.
  • X = Diameter of polyimide tube (refer to the table 1).
  • Y = Diameter of Stainless Steel tube is approx. 50% larger than Polyimide tube.
