A tampon with an absorbent body of which at least a part of its volume is made from an absorbent material and having a middle part, a distal end and a proximal end, and which is connected to an extraction device. The volume of absorbent material in such a tampon is designed to absorb between 0.5 g and 4 g, preferably 3.5 g, of liquid.

A non-invasive endometrial sample collector has an outer body of absorbent material configured for insertion into a vaginal cavity of a patient such that a distal end of the body is positioned proximate a uterine cervix of the patient. The collector has an internal collection assembly disposed within the outer body of absorbent material. The internal collection assembly includes a funnel having an opening at the distal end of the outer body configured to face the uterine cervix when the outer body is positioned in the vaginal cavity, and a reservoir in fluid communication with the funnel. During a menstruation cycle of the patient when endometrial tissue cells are shed within menstrual fluid that passes through the uterine cervix, or during any type of normal or abnormal bleeding episode, at least a portion of said fluid is directed to the reservoir via the funnel under the force of gravity.

Tampons including an elongate body and a removal string extending from a removal end of the elongate body. The tampons may include a flow path that directs menses across the elongate body. The tampons may include a plurality of longitudinal ribs crossing the flow path. The plurality of longitudinal ribs facilitate expansion of the elongate body.

Tampons including an elongate body and a removal string extending from a removal end of the elongate body. The tampons may include an absorbent material and a spiral flow path that directs menses across the elongate body. The spiral flow path includes at least one complete turn around the longitudinal axis of the elongate body.
