Reusable Concentric Electrode Cables (a.k.a., "Needle Holders")
Concentric needle electrodes for EMG typically require a reusable cable (aka "needle holder") to connect the concentric needle to the electromyography machine. Each manufacturer or brand has their own cable, so get Model SFC for Technomed concentric needles, and BIOC-NH for BIONEN concentric needles.
