A single-use radiological imaging aid includes an adhesive-backed tape and a backer covering the adhesive. Both the tape and the backer include radiopaque indicia. The indicia on the tape may include locating and/or measurement markings to identify, locate and/or measure anatomical features in a radiological image. The indicia on the backer includes alphanumeric and/or graphic symbols which define a blocking field. When the backer is intact over the adhesive surface of the tape, the blocking field on the backer is in substantial registration with the indicia on the tape. The backer must be removed prior to use of the tape in a radiological image, or else the blocking field will obscure the indicia on the tape in a scanned image. This design ensures that the tape will be properly adhered to a patient's skin prior to imaging and will be used only once.

Single-use radiological imaging aid

Self-centering valvulotome (V) having a flexible cable (1) partly and slidably disposed within a protective sheath (2), a cutting unit (4), having at least three radially mounted, retractable cutting blades, attached to the cable at its distal end, and a dual-purpose control mechanism attached to the cable at its proximal end. Each retractable cutting blade comprises a free-floating cutting head and a flat spring section, which biases the cutting head against the venous wall. The control mechanism comprises a T-valve segment disposed partly within the proximal end of the protective sheath. A pull handle affixed to the proximal end of the cable can engage the T-valve such that a fluid-tight seal is created, thereby allowing the introduction of a diagnostic or therapeutic fluid to the protective sheath via an access port in the valve.
