摘要：
A catheter includes a proximal portion and a distal portion, the distal portion including an arcuate portion. The catheter further includes a rotating portion, the rotating portion connecting the proximal portion and distal portion, the rotating portion including a first piece and a second piece, wherein the first piece and second piece create a snap fit. Methods of using the catheter include threading the inserted catheter through the vasculature and allowing the distal portion to freely rotate about an axis defined by the rotating portion responsive to any tortuosity in the vasculature.
