Hysterosonography/endometrial biopsy catheter

A hysterosonography/endometrial biopsy catheter is a flexible, single-use tube used in gynecological procedures to combine saline infusion sonohysterography (SIS) with endometrial tissue sampling. It helps visualize the uterine cavity via ultrasound while allowing simultaneous biopsy collection, improving diagnostic accuracy during one procedure.

These devices are typically regulated as single-use medical instruments, often requiring compliance with general medical device standards. They are commonly supplied sterile and intended for vaginal insertion, with saline infusion and biopsy capabilities integrated into a single design.
