Abstract
Radiopaque marker for a catheter includes a collar having a ring shape defining a longitudinal center axis therethrough and at least one helical member extending longitudinally from the collar. A second collar can be provided spaced longitudinally from the first collar. Additionally, a second helical member can extend longitudinally from the collar and be coaxially intertwined with the first helical member in a double helical configuration. The helical member can define a compression spring structure having longitudinal, transverse, and torsional flexibility. A catheter having such a marker and a method of making the marker are also provided.
