    What are hemorrhoids?

    Hemorrhoids are a collection of blood vessels in the lower rectum. Everyone is born with hemorrhoids as a normal part of the vascular tissue in the rectum. However, hemorrhoidal tissue can enlarge and may require treatment.

    What are common symptoms of hemorrhoids?

    Common hemorrhoid symptoms that may require treatment include:

    • Rectal bleeding during bowel movements
    • Prolapse (tissue comes outside of anus) during bowel movements
    • Itching or discomfort in the anal area

    What is hemorrhoid energy therapy using the HET™ bipolar system?

    The HET™ bipolar system is a proprietary technology that allows for the gentle, simple and efficient non-surgical treatment of symptomatic low grade hemorrhoids in a single procedure. The HET™ bipolar system treats hemorrhoids in the area where the human body doesn’t feel much pain, using low power energy. Ask your physician about how hemorrhoid treatment above the “pain line” could result in a procedure with minimal discomfort.

    How is the HET™ bipolar system different from other hemorrhoid treatment options?

    Treatment with the HET™ bipolar system is a fast, efficient procedure.

    Many hemorrhoid treatment options often require multiple procedures to treat the hemorrhoids, including banding and infrared coagulation procedures. In contrast, the HET™ bipolar system can be used to treat multiple hemorrhoids in a single therapy session.

    The HET™ bipolar system enables a more efficient treatment of grades I and II internal hemorrhoids compared to banding because it typically only needs one session.

    Is the HET™ bipolar system right for treating your hemorrhoids?

    While both internal and external hemorrhoids are generically called “hemorrhoids,” these conditions are different – they cause different symptoms and are treated differently.

    Your doctor can tell you whether your hemorrhoid symptoms are internal or external. Grades I and II internal hemorrhoids are considered mild-to-moderate and can be treated with non-surgical methods using the HET™ system.

    Is hemorrhoid energy therapy painful?

    In one 23 patient study, 100% of patients surveyed reported no pain or discomfort from treatment of internal hemorrhoids when the HET™ bipolar system was used.1

    How does the HET™ bipolar system work?

    The HET™ bipolar system is inserted into the rectum and low power energy is delivered to the blood supply feeding enlarged hemorrhoids – not to the hemorrhoid itself. This causes the blood volume to be reduced and the hemorrhoid to shrink in size.

    Is hemorrhoid energy therapy covered by my insurance plan?

    The HET™ bipolar system is covered by Medicare and most major insurance carriers.2

    Important Risk Information:

    This document is not meant to replace medical advice. All procedures for treating hemorrhoids carry the potential for side effects. Common side effects associated with treatment for internal grades I and II hemorrhoids include the potential for pain, discomfort and/or bleeding from the treatment site. Inform your clinician of any medications you are taking. Be sure to listen to your healthcare professional and ask questions if you don’t understand any of their instructions. Double-check with your physician to see if there is anything else you should be doing that is not covered by this document, and make your clinician aware of any side effects you experience.
