Abstract:
A matched group of graduated catheters the matched group comprising a first graduated catheter and a second graduated catheter, the first catheter being reproducibly seatable within a bodily lumen of a subject and comprising1) a first tubular body having a distal portion, a proximal portion, and a first lumen extending longitudinally therein from the proximal portion, 2) a first expandable member on the distal portion of the first tubular body. 3) a first indicator associated with the first tubular body for indicating a first reference position within the bodily lumen; and 4) a radiation source positioner disposed within the first lumen, the second catheter being reproducibly seatable within the bodily lumen and comprising1) a second tubular body having a distal portion, and a proximal portion configured differently from said proximal portion of said first tubular body, wherein said different configuration accommodates the use of a locater member, 2) a second expandable member on the distal portion of the second tubular body, and 3) a second indicator associated with the second tubular body for indicating a second reference position within the bodily lumen wherein the first reference position when the first catheter is seated in the bodily lumen has a known relationship to the second reference position when the second catheter is seated in the bodily lumen.
