Abstract:
1. A device for dimensioning a circumference of a cavity comprising: a body having a lumen and a distal aperture in communication with the lumen; a longitudinal member extending through the lumen having a distal end and a proximal end, the longitudinal member capable of slidable movement through the body between retracted and advanced positions; a flexible looped member adapted to conform to a circumference of a cavity, wherein the flexible member is operatively connected to the distal end of the longitudinal member such that upon retraction of the longitudinal member, the flexible member retracts into the lumen and when the longitudinal member is moved toward the advanced position, the flexible member is advanced out of the lumen and expands to conform to a dimension which approximates the circumference of the cavity, the proximal end of the longitudinal member having at least one marking, the marking corresponding to a predetermined circumference of the flexible member; and a pin extending through the lumen of the body proximate to the distal aperture, the pin positioned between two sides of the looped member, the pin adapted and configured to assist spreading of the looped member as the looped member is advanced out of the lumen.
