Patent ID: 8162891

Claim:
A support catheter comprising: a catheter body having a length in the range from 100 cm to 180 cm, a proximal region, a distal region, and a single contiguous lumen extending through the proximal and distal regions, the single contiguous lumen having a proximal portion through the proximal region of the catheter body and a distal portion through the distal region of the catheter body; wherein the proximal region with the proximal portion of the single contiguous lumen and the distal region with the distal portion of the single contiguous lumen are configured to extend into a blood vessel through a vasculature access site; wherein a cross-sectional area of the proximal portion of the single contiguous lumen is larger than a cross-sectional area of the distal portion of the single contiguous lumen so that two or more devices can be held in the proximal portion of the single contiguous lumen while the distal portion of the single contiguous lumen is large enough to accommodate only one of the devices; and wherein the proximal portion of the single contiguous lumen of the catheter body is configured to simultaneously accommodate the two or more devices therein while positioned within the blood vessel.
