Abstract:
A medical device for measuring an anatomical structure comprising a first reference and a second reference within a body passage during a medical procedure which uses an endoscope, comprising:an elongate member comprising a wire guide that includes a distal tip, a distal portion, and an indicia pattern, wherein the indicia pattern, which is at least partially located on the distal portion, includes a first system of indicia and a second system of indicia; wherein the first system of indicia is located at least partially on the distal portion and includes a series of uniquely identifiable scale reference markings comprising at least two different types of markings, the wire guide so configured to be positionable within the endoscope such that when the distal portion is at least partially extended distally from the endoscope during the medical procedure, at least a portion of the first system of indicia is viewable to the operator with the endoscope while the distal portion of the wire guide as viewed with the endoscope is positioned relative to the first reference of the anatomical structure to obtain a first measurement, and at least a portion of the first system of indicia is viewable to the operator with the endoscope while the distal portion of the wire guide as viewed with the endoscope is positioned relative to the second reference of the anatomical structure, such that the anatomical structure within the body passage can be measured by comparing the first measurement to the second measurement; wherein the second system of indicia includes a pattern of closely spaced markings so configured to readily indicate motion of the wire guide and spaced such that at least a portion thereof will fall within a viewable region located adjacent to an unsheathed portion of the wire guide during the medical procedure, the pattern of closely spaced markings located at least partially between selected ones of the scale reference markings.
