Stimulator Cable - BNC to Flexible 24-gauge silver wire electrodes The C-STIM-BNC-F2 is a stimulator cable with a male-BNC connector for attachment to female-BNC outputs or adapters on stimulators. The lead wires on the other end of the C-STIM-BNC-F2 have flexible 24-gauge silver wire electrodes (80 mm long) that can be shaped to conform to the surface of tissues or organs, like the coils in Figure 4. These elec- trodes can be used for stimulating hearts or muscles without damaging the organs.
