Claim 0:
1. A vascular introducer system, comprising:
a) a first vascular introducer comprising a deflectable first catheter sheath extending along a first longitudinal axis to a first distal end portion, the first catheter sheath defining a first lumen having a first interior surface with a first inner diameter, wherein a first tubular insert having either a first hexagonally-shaped or a first octagonally-shaped cross-section perpendicular to the first longitudinal axis is connected to the first interior surface of the first catheter sheath; and
b) a second vascular introducer comprising a deflectable second catheter sheath extending along a second longitudinal axis to a second distal end portion, the second catheter sheath defining a second exterior surface with a second outer diameter that is less than the first inner diameter of the first interior surface of the first catheter sheath, wherein a second tubular coupling having either a second hexagonally-shaped or a second octagonally-shaped cross-section perpendicular to the second longitudinal axis and that is the same shape as the first tubular insert is connected to the second exterior surface of the second catheter sheath,
c) wherein, when the second catheter sheath is inserted into the first lumen of the first catheter sheath so that the first and second longitudinal axes are co-axially aligned, the second hexagonally-shaped or the second octagonally-shaped tubular coupling engages the corresponding first hexagonally-shaped or the first octagonally-shaped tubular insert of the first catheter sheath to provide for relative longitudinal movement while inhibiting relative rotational movement of the first and second catheter sheaths so that the first and second distal end portions can be deflected in unison and independently.
