ABSTRACT:
A dual-lumen catheter for use in a body vessel. The catheter includes an elongate shaft having a longitudinal axis and defining at least a first and a second lumen. The elongate shaft has a cross sectional width normal to the longitudinal axis and a webbing section disposed between the two lumens. The webbing section has a webbing length less than the cross sectional width to reduce a tendency of the shaft to bend perpendicular to the webbing length when the shaft is rotated.
