Safe, simple, effective, portable

Thermablate EAS is a fully automated balloon treatment for heavy bleeding used to carry out global endometrial ablation in just 2 minutes…with the press of one button.




Well tolerated

Portable handheld generator

The device is entirely self-contained, requires minimal set-up, and plugs directly into an electrical wall outlet for immediate use.

Read what RCOG says about Thermablate here: second generation ablation devices.

Thermablate is easy to operate: fluid pressure and volume are entirely monitored by the unit itself, and need not be supervised continuously by the operator. Thermablate does not cause charring and adhesions post ablation, allowing for inspections of the cavity even after several years, reducing the need for hysterectomy. 

Thermablate EAS has successfully reduced total treatment time of global ablation to less than 2.5 minutes, making it a simple, safe and effective procedure that can be conducted conveniently in an outpatient setting.

Safe, simple, effective, portable

  • Fully automated
  • Handheld generator
  • Minimal set up required. Safely treats a variety of uterine shapes and sizes.
  • The Treatment Control Unit heats the fluid prior to treatment and provides simple step-by-step instructions throughout the procedure
  • The pre-filled Thermablate EAS disposable cartridge is comprised of a slim 6mm diameter catheter, silicone balloon and the glycerine fluid. The thin, pliable, silicone balloon inflates three times to ensure optimal contact with endometrial tissue even in large or irregular cavities.

Safe, simple, effective, portable: Efficacy and Tolerability

In an international multicentre study, which included 120 women with menorrhagia, it was found that following Thermablate Balloon endometrial ablation the patient satisfaction rate was 85% (this is consistent with other ablation options as per RCOG here)

No intra or postoperative adverse events reported.

Outpatient or ambulatory gynaecology clinics are usually found within a hospital’s outpatient department. These clinics utilize the “see and treat” or “one stop” approach to outpatient gynaecological care.

Minor surgical procedures, including endometrial ablation, can be easily and conveniently performed in this type of setting due to the numerous advances in minimally invasive surgical techniques.

The benefits of performing endometrial ablations under local anaesthesia:

  • Less costly for the hospital and healthcare system
  • Quicker treatment time for both patient and physician
  • Shorter recovery time and avoidance of risks associated with general anaesthesia
  • Increased efficiency for physicians who can perform a greater number of procedures in less time.

The Thermablate system’s compact design, ease-of-use and short treatment time make it an ideal ablation system for use under local anaesthesia

“Thermablate EAS is an extremely well-tolerated device ideal for use in the outpatient or office setting.” (1)

Both patients and physicians report low pain scores during and after treatment with Thermablate under local anaesthesia. It is common for patients to be discharged approximately 1-2 hours after a procedure, making the need for recovery time and resources minimal.

Clinical data has shown the following results when patients were treated with Thermablate under local anaesthesia:

  • 100% of patients return to normal activity within two days
  • 93% of patients would have the procedure again
  • 88% would recommend the procedure to a friend
  • Majority of patients treated are discharged within 30 minutes
  • Thermablate patients reported lower pain levels both intra and post operatively compared to those treated with radio frequency ablation

Patient Assessment and Selection

Many patients will be good candidates for outpatient endometrial ablation. It is important to discuss all treatment options and determine important factors such as:

  • A good way to assess level of pain tolerance is by conducting an in-office endometrial biopsy and/or diagnostic hysteroscopy
  • Ease or difficulty of cervical dilation
  • Uterine position and size

For a complete list of the Patient Selection Criteria and other contraindications, please refer to the Thermablate EAS Treatment Protocol

Below is a sample list of key equipment and supplies that are useful to successfully carry out a treatment with Thermablate under local anaesthesia:

  • Thermablate Portable Treatment Control Unit and a disposable balloon cartridge 
  • Diagnostic hysteroscope and / or ultrasound machine 
  • Standard sterile gynaecology tray including speculum, tenaculum, sterile drapes, etc.
    • Have a look at our GOKit, especially designed to provide you with the essentials in a light weight, simple to use single use tray with excellent quality
  • Equipment to perform a paracervical block
  • Cervical dilators up to 7mm (Or GOKit)
  • Sounding device (disposable or reusable) (Or GOKit)
  • Wing Needle Hysteroscopic injection needle for pain management (optional)

Please note: If using a Wing Needle for the injection of intrauterine anaesthesia, an operative hysteroscope with a slim outer sheath and 5 French working channel is required.

The most common technique used to manage patient pain levels during an outpatient treatment with Thermablate is the paracervical block. The specific medication administered and protocol followed should be reviewed and decided prior to commencing the procedure.

A number of different local anaesthesia protocol variations are available below:

Other Important Considerations

To offer patients the optimal outpatient experience along with proper medication for pain management, it is important that patients feel as relaxed and as comfortable as possible. This procedure can be managed so that the patients is completely pain free (mild discomfort as with period pains is common after the procedure).

To facilitate this, the clinic should consider the following:

  • Adequate nursing support is essential to the success of the treatment
  • One nurse to assist the doctor and to ensure the patient is comfortable throughout the treatment (talking to the patient, asking for current comfort levels through out the preparation and the 2 minute procedure.)
  • Designated recovery area with bed or reclining chair
  • Privacy both before and after procedure
  • Patient support as needed and requested
