Intrauterine measurement device

Abstract

Uterine sounds are provided including an insertion member having a distal end, a proximal end, and a lumen, wherein the insertion member is configured for insertion through an endocervical canal. A measurement member is provided having a distal end and a proximal end, the measurement member configured to move within the lumen of the insertion member, where the distal end can protrude from the distal end of the insertion member and is configured for insertion to approximately the fundus of a uterine cavity. An expansion member is also provided transitionable between an unexpanded and expanded state, wherein the unexpanded position is configured to pass an internal cervical os, and the expanded position is configured to prevent passage. Once the expansion member is positioned, the measurement member is positioned relative to the insertion member to establish a measurement of a depth of the uterine cavity.
