How Does it Work
HIVEC® treatment requires the use of a small machine that is called The COMBAT BRS system. The system sits alongside you during your one-hour treatment and is connected to your catheter via a closed circuit of small tubes.
The COMBAT BRS system warms the chemotherapy drug before it enters your bladder through a special catheter. The chemotherapy drug is heated to a temperature of 43°C which is a similar temperature to that of a warm bath.
It is then gently re-circulated around your bladder and back through the system up to four times a minute. This is to make sure that the inside of your bladder is kept at a constant target temperature of 43°C and that the chemotherapy drug is well distributed so the whole area is treated.
When the COMBAT BRS system is switched on it will gently start to pump the warm chemotherapy drug around your bladder. The normal temperature inside you bladder is around 37°C and the HIVEC® treatment will only increase the temperature by a few degrees to 43°C.
Therefore you may or may not notice a sensation of warmth during this time, not everyone does.
Those patients who do report a feeling of warmth say that it is not uncomfortable, perhaps feeling like a warm bath or a warm hot water bottle placed on the abdomen.
All of the heated chemotherapy drug stays entirely within your bladder and the tubes connected to the system. After one hour the system will gently drain the chemotherapy drug out of your bladder through your catheter and into a special bag to dispose of safely.
