摘要： Over-the-wire self-sizing, self-centering valvulotomes sufficiently designed to cut valves through a wide range of vein diameters and adjust to the internal diameter of a vein as the valvulotome is being drawn through the vessel, and methods of use thereof during certain medical procedures that involve splitting valves, are disclosed herein. In an embodiment, an over-the-wire valvulotome includes a catheter having a proximal end, a distal end, and a longitudinal axis therebetween, wherein a first portion of a plurality of cutting tools engage the catheter at the distal end, and wherein an actuation mechanism engages the catheter at the proximal end; a retainer for temporarily shielding a second portion of the plurality of cutting tools, wherein the second portion includes cutting blades; and a sheath slidably moveable over the plurality of cutting blades, wherein the catheter and the retainer have internal diameters configured for passing over a guidewire.

摘要： 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.
