Abstract

A multipurpose catheter includes an un-tapered portion and a tapered portion, the latter being disposed distally of the former. The catheter has an arrangement of echo reflective features over at least a portion of the tapered portion. The echo reflective features may be echo reflective solely due to their shape, or may be made of radio opaque materials, and thus may provide a degree of echogenicity not only due to their material but also due to the reflectivity of their shape.
