Design and evaluation of a low threshold, porous tip lead with a mannitol coated screw-in tip ("Sweet Tip").
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.
