The SD series of snares and the predicated snares are all designed to endoscopically resect tissue from within the GI tract.

The SD series of snares and the predicated snares are all designed to endoscopically resect tissue from within the GI tract. The SD snares consist of a proximal end control handle, an electrical connection cord (A-cord), a flexible catheter-like tube, and a distal end snare loop. The detachable control handle contains the electrical connections which permit the snare loop to be connected to an electrosurgical generator via the A-cord. The distal end snare loop may be positioned around the target tissue by movement of a slider on the control handle. The tissue is resected by a combination of mechanical strangulation and electrosurgical current.
