Technology

The breast cancer treatment sector is split between chemical or biological agents, and devices aimed at killing or removing cancerous tumors. Medifocus enjoys a decided advantage, as demand for procedures resulting in cosmetically acceptable outcomes is growing. Medifocus' minimally invasive, non-toxic, focused microwave technology platform is able to target and treat tumors 1 – 8 cm in diameter, unlike radio frequency devices or laser-induced thermotherapy. Additionally, the system can be used to eradicate microscopic breast tumors that cannot be seen by surgeons.

When using Medifocus' patented focused-microwave technology, a minimally invasive disposable catheter sensor is inserted into the breast under ultrasound guidance to provide feedback signals for microwave focusing and temperature measurement.

The breast is then immobilized by compression, which also serves to reduce blood-flow and increase the efficiency of heat delivery for effective treatment, and microwave energy is applied to the breast via two parallel-opposed microwave applicators.

A proprietary feedback, tracking, and control mechanism ensures that the microwave energy is focused on the center of the tumor, while a computer algorithm controls the amount of energy applied to the tumor, and monitors the temperature to ensure optimum effectiveness.
