Patent ID: 8277395

Claim:
A device configured to be inserted into a body lumen and used to measure a size of the body lumen, comprising: a proximal handle assembly; a distal member including a proximal end member distal the proximal handle assembly, a distal end member distal the proximal end member, and a radially expandable member connected to the proximal end member and the distal end member and configured to expand from a contracted state to an expanded state within the body lumen to measure the size of the body lumen; a control member fixedly connected to the proximal handle assembly and directly and fixedly connected to the distal end member of the distal member such that the control member and the distal end member are immovable relative to each other, actuation of the proximal handle assembly causing the expandable member to expand; and a measurement indication member for displaying a value indicative of a size of the expandable member.
