Abstract:
An apparatus and method for measuring the size of a body passage is provided. The apparatus comprises a flexible strip having first and second ends. At least one aperture is disposed on the strip between the first and second ends. An indicia of body passage circumference is disposed on the strip in association with the at least one aperture. The body passage may be measured by inserting the strip into a dissected tunnel around the body passage, manipulating the strip such that the strip substantially surrounds the body passage, and observing the indicia on the strip to generally determine the circumference of the body passage.
