Claim 12:
13. A method, comprising:
a) providing a first vascular introducer comprising a deflectable first catheter sheath extending along a first longitudinal axis to a first distal end portion, the first handle assembly comprising a first mechanism that is configured to effectuate deflection of the first distal end portion of the first catheter sheath, wherein the first catheter sheath comprises a first interior surface defining a first lumen having a first inner diameter, and connecting a first tubular insert comprising either a first hexagonally-shaped or a first octagonally-shaped cross-section perpendicular to the first longitudinal axis to the first interior surface of the first catheter sheath;
b) providing a second vascular introducer comprising a second handle assembly connected to a deflectable second catheter sheath extending along a second longitudinal axis to a second distal end portion, the second handle assembly comprising a second mechanism that is configured to effectuate deflection of the second distal end portion of the second catheter sheath, wherein the second catheter sheath comprises a second exterior surface defining a second outer diameter that is less than the first inner diameter of the first interior surface of the first catheter sheath, and connecting a second tubular coupling comprising either a second hexagonally-shaped or a second octagonally-shaped cross-section perpendicular to the second longitudinal axis to the exterior surface of the second catheter sheath, wherein the first tubular insert and the second tubular coupling have the same hexagonal or octagonal shape;
c) inserting the second catheter sheath of the second vascular introducer into the interior lumen of the first catheter sheath of the first vascular introducer;
d) engaging the second tubular coupling connected to the exterior surface of the second catheter sheath with the first tubular insert connected to the first interior surface of the first catheter sheath; and
e) actuating at least one of the first and second mechanisms of the respective first and second handle assemblies to effectuate deflection of at least one of the first and second distal end portions of the respective first and second vascular introducers.
