Technical aspects of the Thermablate EAS

The Thermablate EAS system consists of a light weight, hand-held, automated Treatment Control Unit (TCU) and a single-use disposable catheter balloon cartridge.  The cartridge contains 28ml of a biocompatible treatment fluid.  It is connected to the TCU (Treatment Control Unit) which heats the fluid to a temperature of 173°C in 8 minutes. This heating process takes place during patient preparation.

 

The physician then inserts the 6mm, heat shielded, soft-tipped catheter into the uterine cavity to the predetermined depth, and initiates treatment with a simple finger trigger.  The TCU’s pneumatic system transfers the fluid through the catheter, inflating the silicone balloon within the cavity to a set pressure level of 220 mmHg. During treatment, the system performs a depressurization and repressurization cycle 3 times to maintain consistent balloon surface contact with the uterine cavity.  This also creates uniform temperature of the fluid within the balloon.  Total treatment time is 2 minutes and 6 seconds. 

 

The treatment parameters of time, temperature, and pressure are all controlled by the Thermablate EAS microprocessors.  This is different from other balloon ablation systems which require manual adjustments by the user.  An easy to read LCD display on the TCU provides pertinent information and instruction to the user at every step of the procedure.  Due to the ease of use, small diameter catheter, short treatment time, and minimal anesthesia/analgesia requirements, allow Thermablate EAS is ideal for use in an office or outpatient setting.
