Microwave ablation

What microwave ablation is

Microwave ablation is a thermal ablation technique that delivers microwave energy through a thin antenna placed into a tumour. The energy agitates water molecules in the surrounding tissue, generating heat that produces coagulative necrosis within a defined ablation zone.

Compared with radiofrequency ablation (RFA), microwave ablation can create larger ablation zones in less time and is less affected by the heat-sink effect from nearby blood vessels. It is delivered percutaneously under ultrasound or CT guidance and is used for tumours in the liver, lung and kidney.

How the procedure works

The procedure is planned and carried out by the treating physician using image guidance throughout. A typical case follows these stages:

• Planning. The physician reviews imaging to define the target lesion, plan the antenna path and set the intended ablation margin.
• Antenna placement. A cooled-shaft antenna is advanced into the tumour percutaneously under ultrasound or CT guidance, with position confirmed on imaging before energy is applied.
• Energy delivery. The MaxBlate generator delivers 2450 MHz microwave energy through the internally cooled antenna, heating the tissue to produce coagulative necrosis over the planned zone.
• Confirmation of margin. The physician reviews imaging after ablation to assess the treated zone against the planned margin and decides whether further treatment is needed.

Equipment we supply

We supply Canyon MaxBlate microwave ablation systems, with Canyon as the OEM. The range covers two generator power levels paired with 2450 MHz internally cooled antennas:

• Canyon MaxBlate KY-2100A (150 W). Higher-output generator for microwave ablation cases.
• Canyon MaxBlate KY-2000A (100 W). Generator option at 100 W output.
• Cooled-shaft antennas (2450 MHz). Internally cooled antenna families used with the MaxBlate generators.

Who it is for

Microwave ablation systems are used by interventional radiologists, surgical oncologists and other treating physicians who perform image-guided tumour ablation. Patient selection and the choice of treatment remain a clinical decision made by the treating physician.

Why Technoray

As an authorized distributor founded in 2010, with offices in Lahore, Islamabad and Karachi, we support the full equipment lifecycle rather than the sale alone:

• Installation and commissioning. We deliver, install and commission the generator and antenna setup at your site.
• Applications training. We train your clinical and biomedical teams on operating the system and handling antennas.
• Service and maintenance. We provide service and preventive maintenance, including annual maintenance contracts (AMC).
• Consumables resupply. We keep your antennas and case consumables resupplied so your schedule is not interrupted.

Frequently asked questions

When is microwave preferred over RFA?

Microwave ablation can produce larger ablation zones in less time and is less affected by the heat-sink effect from nearby blood vessels, which can make it a consideration for certain lesions. The choice between microwave ablation and RFA for a given patient is made by the treating physician.

What consumables does each case use?

Each case uses a 2450 MHz internally cooled antenna along with the related setup consumables. We resupply antennas and consumables so your team can plan case volumes without running short.

Do you train our team and service the system?

Yes. We provide applications training for your clinical and biomedical staff at installation, and we offer ongoing service and preventive maintenance, including annual maintenance contracts.
