EZ-HSG Catheter is designed to simplify and improve sonohysterography and hysterosalpingogram. EZ-HSG Catheter is used to access the uterine cavity for injection and retention of fluid for SIS and HSG. FoamCone instead of balloon simplifies SIS and HSG reduces cost. Users will find several benefits of this design over balloon catheter. Simply introduce the catheter by gently pushing the uterine cavity. Place the FoamCone segment high in the cervical canal to block the internal os. Unlike balloon catheters, there is no need to pull back on the catheter during the procedure to reduce fluid leak-back. Inject a small amount (5cc-15cc) of fluid into the uterine cavity. Uterine cavity will distend and the uterine distension usually will last for prolonged period for SIS and HSG. Re-injection is rarely necessary. After initial injection, the syringe can be disconnected for easier scanning (ultrasound or fluoroscopy). Resolution of the image is usually better due to absence of balloon in the lower uterine cavity.

Another benefit is the cost of the catheter is also reduced significantly due to single channel design. All these benefits will help increase use of EZ-HSG Catheter in GYN Sonography.

EZ-HSG Catheter is available in three sizes to accommodate various sizes of the cervical canal for improved endocervical seal.

Indications
• Infertility
• Menorrhagia and other abnormal uterine bleeding
• Dysmenorrhea due to uterine synechia
• Suspected endometrial polyp
• Submucous fibroid
• Amenorrhea due to uterine synechia (Asherman Syndrome)
• Congenital uterine abnormality

Contraindications
• Suspected pregnancy
• Suspected pelvic inflammatory disease

Procedure
• Insert speculum and visualize cervix
• Select appropriate size catheter to match cervical canal diameter
• Size: Small-postmenopausal and stenotic cervix; Medium-Sonography (SIS); Large- Incompetent Cervix and Hysterosalpingogram.
• We recommend initial cervical dilatation or use of prostaglandin for stenotic and post menopausal patients.
• Insert catheter with “Foam Cone” segment completely inside the cervix to seal internal os
• Reinsert the catheter if the catheter is kinked & fluid can not injected.
• Inject Fluid and distend uterine cavity
• Close the Stopcock and remove syringe ( and speculum).
• Perform HSG/SIS in the usual way
• Endometrial distension usually maintains throughout the procedure
