Various embodiments of a measurement device used to measure a size of a lumen and related methods of use are disclosed. For example, the device may include a proximal handle, a distal member including a radially expandable portion, a control member connecting the proximal handle to the distal member, and a measurement indication member for displaying a value indicative of a size of the expandable portion. The radially expandable portion may be configured to expand from a contracted state to an expanded state to measure the size of a lumen.
