摘要：
A device for placement externally of a body fluid flow conduit, includes a tubing portion defining a longitudinally extending cavity for receiving the conduit. The longitudinal cavity of the tubing portion is substantially free of ribs or grooves. The center line of the longitudinal cavity follows a substantially helical path with a helix angle which is less than or equal to 65°. An amplitude of the helix is less than or equal to one half of the internal diameter of the tubing portion.
