Intrauterine imaging medium catheter

An intrauterine imaging medium catheter is a flexible tube used to deliver contrast agents or saline into the uterus for diagnostic imaging procedures. It enables visualization of the uterine cavity and fallopian tubes during hysterosalpingography or enhances transvaginal ultrasound imaging through saline infusion sonography.

This device is designed for single-use only and typically features a dual-lumen design with an inflatable balloon or seal near the tip to occlude the cervix during fluid instillation. It may include accessories such as a stylet or syringe for catheterization and is regulated as a medical device intended for temporary, diagnostic use within the uterine cavity.
