Intended Use
Disposable Microwave Therapeutic Antennas is used with the Microwave Therapeutic System, which is indicated for the coagulation (ablation) of soft tissue. The Disposable Microwave Therapeutic Antennas is not intended for cardiac use.
Device Story
Disposable Microwave Therapeutic Antennas are puncture needles used for soft tissue ablation. The device consists of a radiator (needle tip/shaft), handle, and microwave cable. During surgery, the antenna is placed into the tumor target area under imaging guidance (CT, US). The microwave generator transmits energy through the coaxial cable to the antenna, where it is radiated into tissue. Water molecules in the tissue absorb the microwave energy, transforming it into heat, which causes rapid temperature rise and loss of tumor tissue bioactivity. The device includes a thermocouple in the handle to monitor needle temperature, ensuring it does not exceed 45 degrees. Cooling is provided by pumped normal saline. The device is used in clinical settings by physicians, provided sterile for single use.
Clinical Evidence
No clinical data. Bench testing only, including electrical safety (IEC 60601-1), electromagnetic compatibility (IEC 60601-1-2), microwave therapy performance (IEC 60601-2-6), shelf-life validation, packaging verification (ISO 11607-1), sterilization validation (ISO 11135-1), and biocompatibility (ISO 10993). In vitro ablation studies were conducted to verify performance.
Technological Characteristics
Materials: Medical stainless steel (304SS), ceramics, ABS, nylon, PTFE. Sensing: Thermocouple for temperature monitoring. Energy: Microwave (2450MHz). Connectivity: Standalone antenna for use with microwave generator. Sterilization: Ethylene Oxide (EO). Software: None (mechanical/hardware accessory).
Indications for Use
Indicated for coagulation (ablation) of soft tissue. Not intended for cardiac use.
Regulatory Classification
Identification

## 8. SE Conclusion
The proposed device is equivalent with respect to the basic design and function to that of the predicate device. It doesn't have new intended purposed, new target populations, and new users. The differences between the predicate, reference device and proposed device do not raise new questions of safety or effectiveness. The proposed device is substantial equivalence to predicate device (K183153).
