Patent ID: 8348856

Claim:
An endometrial biopsy device, comprising: a flexible coaxial structure, comprising an obturator within a sheath, the obturator being configured to be displaced with respect to the sheath along the coaxial axis by a force applied at a proximal end, and the sheath having a cylindrical tip at a distal end configured to be inserted into an endometrial cavity; a disruptor, at a distal end of the obturator, configured to disrupt an endometrial tissue surface to free cells therefrom, having a first position covered within the sheath and a second position freely extending beyond the distal end of the sheath; and an element, having a fixed position on the obturator proximally displaced from the disruptor, and having a dose clearance with respect to an inner surface of the sheath, such that a retraction of the element from the second position into the first position within the sheath causes an associated suction in a space between the obturator distal to the element and the sheath, to thereby draw and retain a fluid sample proximate to the distal end of the sheath within the sheath.
