Methods: A ‘‘telescopic’’ system was created consisting of: (1) a microcatheter with guidewire. This system fits into
any catheter allowing a 0.035 inch wire. (2) a 4Fr ‘‘delivery’’ catheter. (3) If sharp angles were encountered, the 4Fr catheter was deployed through a 6Fr or larger angulated guiding sheath. This was cut-off 15 cm out of the groin and re-valvulated with a standard short introducer sheath.
In order to be launched at an appropriate angle, the microcatheter was usually passed through a 4 French (Fr) ’’delivery‘‘ catheter. Because of the length of the catheters and the design of the coaxial system, it was often necessary to cut off the guiding sheath about 15 cm distal to the groin in order to allow an adequate distance for manipulation of the shorter 4Fr catheter or delivery of balloons and stents on shorter shafts. In order to reduce bleeding and allow contrast injections if required, the cut-off guiding
sheath was usually re-valvulated by placing a conventional short 6Fr introducer sheath (or other size as required by the sheath Fr size) at the distal end of the guiding catheter.
