Ease of insertion of exposed helical coil tip and tined silicone leads through single cephalic vein.
Since polyurethane was introduced as an insulation material for pacing leads, it has been purported that passing two polyurethane leads through one vein would be significantly easier than passing two bipolar silicone leads. However, this case, in which two bipolar silicone leads were easily positioned via a single cephalic vein, raises the question of whether there is any clinically significant in vivo lubricity difference between the two materials.
