Abstract
A vascular catheter includes a catheter body, an inflatable balloon disposed at the distal end of the catheter body, and an inflation conduit extending from the proximal end of the catheter body to the inflatable balloon. The inflation conduit is disposed on the exterior of the catheter body, minimizing the total cross-sectional area but imparting a non-circular periphery. Catheter whip resulting from the non-circular periphery is reduced by arranging the inflation conduit in a helical pattern over at least a distal portion of the catheter body.
