Claim:
1. A multipurpose catheter, comprising a. an elongated cylindrical untapered portion; b. an elongated cylindrical tapered portion distal of the untapered portion; and c. an arrangement of echo reflective features formed over the tapered portion, the arrangement comprising at least two frustal annuli joined by a straight axial line, wherein the arrangement allows disambiguation of a location of the tapered portion about an azimuthal angle, a position and an orientation when the catheter is visualized using an imaging modality, wherein the echo reflective features include one or more from the group consisting of: dimples, depressions, or bumps, d. wherein the untapered portion and the tapered portion define at least one lumen, and at least one hole located between the two frustal annuli and adjacent to the straight axial line, the at least one hole in fluid communication with the lumen, and e. wherein an imaging modality is sufficient to indicate the location and orientation of a distal end of the elongated cylindrical tapered portion using the arrangement of echo reflective features as formed by the at least two frustal annuli.
