摘要：
A graft includes a flow tubing having a tubing portion defining a flow lumen. The flow lumen of the tubing portion is substantially free of ribs or grooves. A center line of the flow lumen follows a substantially helical path with a helix angle less than or equal to 65°. The amplitude of the helix is less than or equal to one half of the internal diameter of the tubing portion.
