Paddle Lead
A flat, wide neurostimulation electrode requiring surgical laminectomy for placement, contrasting with cylindrical percutaneous leads.
Full Definition
A paddle lead is a type of neurostimulation electrode characterized by its flat, paddle-shaped design with multiple contact points arranged in arrays on the surface. Unlike cylindrical percutaneous leads that can be inserted through needles, paddle leads require open surgical placement through laminectomy due to their width and rigid construction. Paddle leads are primarily used in spinal cord stimulation where they provide broader stimulation coverage and more stable positioning against the dura mater. The increased surface area and multiple electrode configurations allow for more precise field shaping and programming options, though at the cost of more invasive implantation procedures.
Usage
Usage note: Distinguish from paddle-shaped electrodes used in other medical contexts.
