The Acculis MTA system was developed between 2001 and 2005 by a team from Microsulis, the University of Bath's Department of Physics and Leicester Royal Infirmary. The system was CE marked in 2005 and received clearance to be marketed in the USA in 2006. The system uses patented needle-like applicators that quickly and effectively destroy unwanted areas of soft tissue by emitting microwave energy.

The Sulis V^pMTA control unit generates microwave energy and controls its delivery to the applicator. The doctor selects the power level required and the time in seconds that they want the microwave energy applied for. This is dependent upon the size and shape of the lesion being treated. Often the doctor will use several small bursts of energy to precisely and completely coagulate the area of tissue being targeted.

We supply a range of applicators in various sizes and shapes for different procedures. Our applicators have a biocompatible non-stick coating and our Accu2i pMTA has a saline cooled shaft. This focuses the microwave energy on the precise area being treated. The microwave energy is passed from the Sulis V^pMTA control unit down the microwave cable into the applicator, where it emits from the tip.

The design of our applicators ensures that energy is deposited very efficiently into the tissue around the tip of the cylinder. This results in very rapid heating in that area and the creation of an increasing sphere of dead tissue. The doctor may use temperature probes to monitor the temperature of key vessels near the area being treated or to confirm when the heating zone has reached the volume required.
