Premium HSG Balloon Catheters for Diagnostic Gynaecology

Hysterosalpingography (HSG) and sonohysterography (SHG) are critical milestones in a fertility clinic’s evaluation of female infertility. Healthcare providers require reliable, high-performing instruments to accurately map the uterine cavity and fallopian tubes.

Thomas Medical (a MedGyn company) is an industry-leading US manufacturer of single-use women’s health products. Our specialised HSG catheter lineup is designed and manufactured to ensure a minimally invasive, exceptionally precise, yet consistently effective diagnostic procedure. By engineering features that maximize enhanced patient comfort while streamlining clinical workflows, we eliminate the need for painful uterine traction and prevent fluid leakage.

Advanced Features Engineered for Patient Comfort & Clinical Precision

Standard procedures often subject infertile women to high anxiety and physical discomfort. Thomas Medical catheters are engineered to optimize the physical experience of the patient while guaranteeing flawless diagnostic imaging.

• Atraumatic Smooth Tip: Minimizes trauma to the cervical canal during both insertion and removal of the catheter, supporting a gentler patient experience.
• Stable Placement Sheath: Significantly decreases or eliminates the need for a painful cervical tenaculum, reducing patient stress during a pelvic examination.
• Soft, Concentric Balloon: Securely inflates above the internal os to secure the catheter in place. This achieves a tight seal that prevents the backflow and leakage of sterile saline or water-based contrast media.
• Malleable Embedded Stylet (Shapeable Models): The shapeable HS catheter comes equipped with an integrated, flexible stylet. This allows the clinician to pre-set the perfect angle to align with a difficult cervical canal or overcome a restricted, stenotic cervix.
• High Radiopacity (20%): Formulated with 20% radiopaque material so the catheter shaft is instantly and clearly visualizable under fluoroscopic x-ray imaging.
• Patient-Safe Composition: All Thomas Medical catheters are latex-free, PVC-free, and Non-DEHP, protecting patients from potential allergen exposure.

Clinical Application: The HSG/SHG Procedure

During a standard hsg procedure, a healthcare provider or radiologist will insert a speculum to visualize the cervix. The Thomas Medical balloon catheter is gently inserted through the cervix into the lower uterine cavity.

Once the concentric balloon is inflated to secure placement, a water-based contrast fluid or iodinated x-ray dye is slowly introduced. As the dye fills the uterine cavity and fallopian tubes, real-time fluoroscopy or ultrasound imaging allows the clinician to identify structural anomalies, uterine adhesions, or a fallopian tube blockage.

Confirming the patency of the fallopian tubes (or diagnosing due to tubal blockages) is an indispensable step in determining the pathway to an ongoing pregnancy for an infertile couple.

Frequently Asked Questions (FAQ)

When should an HSG diagnostic procedure be scheduled?

An hysterosalpingogram mainly takes place during the early follicular phase—typically a few days following the end of the menstrual cycle (days 7 to 10). This timeline ensures the endometrium is thin for optimal imaging and guarantees the patient is not could be pregnant.

What fluids can be injected using Thomas Medical Shapeable HS Catheters?

Our products are fully compatible with saline (for hysterosonography / SHG) as well as conventional water-based contrast media or iodine-based x-ray dye (for hysterosalpingography procedures).

Are these catheters safe for patients with a latex allergy?

The Thomas Medical Shapeable HS Balloon catheter is latex-free and entirely free of PVC and DEHP, minimizing patient risk and irritation
