A screw‐in transvenous lead has been developed for permanent atrial or ventricular pacing that makes insertion of a fixed helix lead smoother and less complicated. The helix has a mannitol coating that protects the helix during insertion and dissolves in the blood stream allowing the fixation of the helix by screwing it into the endocardium. The Sweet Tip™ lead features a porous tip mesh electrode designed to improve pacing and sensing thresholds, and HP silicone insulation of previously demonstrated reliability.
