Device for measuring the percentage of stenosis in stenosed arteries

摘要

The present invention relates to a device which is intended to facilitate determination of the percentage of stenosis, by applying it directly on the angiograph of the stenosed arteries, characterised in that it comprises a support rule (1) inscribed in a rectangle, comprising at least one rectilinear base (12) and a rectilinear left-hand edge (11) perpendicular to the base (12) in such a way as to form an orthogonal marking, the rectilinear left-hand edge (11) comprising graduated markings (111) which are intended to measure the thickness of the arteries and which are disposed in accordance with an appropriate scale, according to a standardised system of incrementation, the first marking (111), arranged at the junction of the left-hand edge (11) and the base (12), corresponding to the zero graduation, the base (12) also comprising graduated markings (111) which are arranged in accordance with a scale which is identical to or different from the graduation (111) arranged on the left-hand edge (11), the first marking (121), arranged at the junction of the base (12) and of the left-hand edge (11), also corresponding to the zero graduation, the rule (1) also comprising a series of diverging lines, each one having its origin at the junction of the base (12) and the left-hand edge (11) of the rule (1), and each line corresponding to a defined percentage.
