Liger Medical – FAQ
Liger Medical is focused on providing cutting edge medical equipment and solutions for the prevention and treatment of cervical cancer.
Questions and Answers:
A. Literature studies have validated that the outcome clinical efficacy is as good or better with thermocoagulation™ as compared to freezing. Refer to Duncan’s studies as shown in Dolman’s meta-analysis in the website educational section. The Liger Medical thermocoagulator™ uses the latest state-of-the-art technology to reach and maintain the treatment tip accurately at temperature within 0.2°C.
A. They are the same, cold coagulation is a misnomer as it uses heat to cause tissue destruction.
A. The time of 20 seconds and 100°C is the standard used by Duncan in his original work (see references). The treatment time is shown by each blue LED turning off as ¼ of the time is up, and also an audio sound given). When all blue LED’s are off the treatment cycle is completed.
A. Standard treatment of 20 seconds at 100°C has been tested on 50 applications before the low battery charge comes on. On body temperature cervical tissue, more cycles could be experienced. If more than one site on the same patient’s cervix is performed, this needs to be taken into account. When the low battery LED indicator comes on, there still is sufficient energy left in the battery to finish that treatment.
Cleaning and disinfection of the Probe for the HTU-110 Thermocoagulator
The full high-level sterilization is given in the IFU that was sent with each unit on page 5 column 2. Many users follow the method below for cleaning and Hi-level disinfection of the probes.
- Place the silicon cap firmly over the connector end.
- Clean any debrie off the probe with mild detergent and water using a soft cloth or soft brush, then rinse in clean water.
- Place the probes upright in a cup (approximately 5- 6” deep) of ~2.5% gluteraldeyde (Cydex) for 20-60 minutes (some sites use a 0.5% Chlorine solution-Chlorox).
- This allows the connector end not to be immersed in solution which is not necessary as the connecter end is not inserted into the patient nor contacts the patient and need not be sterilized.
- Some users apply a heat cycle of the device to assure that the heated end has reached a sterilization temperature but this is unnecessary and regulatory agencies have not approved this procedure for sterilization. It certainly does sterilize the tip as all viral proteins are denatured above 60’C.
- Rinse the probe end (not the connector end with the silicone cap) with clean, non-contaminated water, thoroughly dry the probe in air.
- Wrap in clean material to keep it from being contaminated before next use.
- The handle can, if needed, be wiped clean with a cloth dampen with a small amount of alcohol.
A. No, they are identical, the protective boot on the base of the battery can be moved to either battery. The batteries can be recharged in a couple of hours.
A. Studies in Chicken breast show a depth just over 5 mm. Duncan’s studies showed this setting was adequate and the overlapping treatment to cover the total lesions was good.

A. The thermocoagulator™ is quicker, easier and simpler to use. The thermocoagulator™ procedure is approximately 20 seconds per treatment as compared to cryotherapy which requires 11 minutes per treatment. The thermocoagulator™ has easy to use rechargeable batteries that use minimal energy, whereas cryogenic requires costly replacement gas cylinders.

Customer Testimonials
“The procedure went well. The 19 mm probe works well and I used it for 2-3 application as the cervix was bulky. The heating time, timer, etc. works well and cervix appears exactly how it appears after treatment with cold coagulation.”
After treating a patient in North Vietnam, she excitedly said: ” I am hopeful to use the TC in Vietnam. I hope for the new therapy, I spoke to my MOH and was approved for a 600 plus woman study”.
“I just used the tc for CIN2-3, I only had to do one cycle, it was great, so smooth. My patient asked me to thank you for making the device so much better than cryo!!!
“It is durable, very portable, the short treatment period makes it very user friendly for both clients and providers.”
“Very convenient, and user friendly.”
“They are both RN’s and were the first two nurses I hired when setting up the cervical cancer screening program back in 2005. Between the two of them they have screened well over 40,000 women, or more and treated thousands with cryo. When I gave them the Liger and they used it they both ran into my office with huge smiles on their faces and were singing the instruments’ graces, as if someone had finally thought of them instead of creating something and forcing them to make it fit their situation.”
I took delivery of a package for our Cervical Cancer Prevention and Training Centre, Battor. Really light devices! Cervical cancer screening and treatment will never be the same again in Battor/Ghana! Simplified! Mobile services becoming more and more available. No need to carry large gas cylinders.
Thermal coagulator is doing so great and it’s a nice machine so to say and very simple to use and assemble. We have both WISAP, the original table top and handheld. But I love the TC unit because of its simplicity to use. I am a national trainer for cervical cancer screening and last month we had a training, where we had participant from 25 out of 28 district in Malawi. In treatment of pre-cancer lesion we oriented all participants on how to use thermal coagulator so that when they are choosing method for treatment they have options. We use both TC (Thermocoagulator) and WISAP (Cold Coagulator), one comment that come out was the TC Unit is very simple to use and not complicated. And many participants really liked it. About the New WISAP. They don’t have a flat probe which makes your probes good for more options during treatment.
A Midwife commented with a bright, excited smile, “The day before yesterday, we just returned from a week-long screen and treatment expedition to remote villages in Zambia and DRC. I treated 30 patients with the Liger Thermocoagulator on the same battery, then yesterday I treated 2 more patients and the battery still did not need recharging”
