Subdermal Needles

Rhythmlink's Subdermal Needle Electrodes offer the quality you expect and deliver the patient comfort that you need. Made of high-tensile strength stainless steel, cleared for both stimulating and recording, we've created a line of needles to meet your every need. Select from a variety of subdermal needle lengths and styles, leadwire colors and lengths, singles or pairs, you have flexibility to select the right set of needle electrodes for you.


Quality recording and stimulating can only occur when you're using a quality product. Rhythmlink's Subdermal Needles are available in different needle lengths and types, leadwire colors and lengths.

Parallel Paired Subdermal Needle Electrodes provide the flexibility to separate the leadwire as much or as little as you need to accommodate each application and patient. Rhythmlink's Paired Needles are available in 13mm or 19mm extended lengths. Both options offer a variety of leadwire lengths and colors.

The Corkscrew Needle is designed to stay securely in place during its application. Rhythmlink Corkscrew Needles are 100% disposable, offer an easy to grip hub and are packaged in individual sterile pouches.
