## Intended Use
The Microwave Therapeutic System is indicated for the coagulation (ablation) of soft tissue. The Microwave Therapeutic System is not intended for cardiac use.
## Device Story
Microwave Therapeutic System (SABERWAVE ECO-200G) is a software-controlled microwave generator delivering energy at 2450 MHz to a disposable ablation needle. System components include microwave source, control system, display, and temperature measurement module. Operates via microwave transistor and power amplifier; energy radiates from applicator tip to target tissue, causing thermal coagulation/ablation. Includes water circulation module for radiator cooling. Used in clinical settings by physicians. Three user-selectable operational modes (timing methods, foot switch/manual control, continuous/intermittent output) allow customization based on tissue type/size. Output affects clinical decision-making by enabling targeted tissue destruction. Benefits include reduced injury/risk compared to multi-needle puncture procedures.
## Clinical Evidence
No clinical data. Substantial equivalence supported by bench testing, including electrical safety (IEC 60601-1), electromagnetic compatibility (IEC 60601-1-2), performance testing (IEC 60601-2-6), thermal effects, temperature monitoring accuracy, and software validation per FDA guidance.
## Technological Characteristics
Microwave generator, 2450 MHz frequency, 0-100W output. Single-channel architecture. Cooling via pumped normal saline. Includes temperature monitoring. Complies with IEC 60601-1, IEC 60601-1-2, and IEC 60601-2-6. Software-controlled.
## Regulatory Identification
An electrosurgical cutting and coagulation device and accessories is a device intended to remove tissue and control bleeding by use of high-frequency electrical current.

Comment 1: Different, predicate device support double channels and two ablation needles can be inserted at the same time for tissue ablation. Our product only supports single channel and only one ablation needle for tissue ablation, Double-needle ablation speeds up the time of a single ablation, but there are injury and risks due to multiple punctures to patient. Single-needle ablation can also achieve the intended use and reduce the injury and risk of multiple punctures to the patient. The subject device has performed the Thermal effects test, performance test according to IEC 60601-2-6, temperature measurement accuracy test, the test result prove that single needle ablation can also achieve the intended use, the performance meet the requirements of IEC 60601-2-6, the temperature measurement accuracy meet the requirements of intended use, the difference does not affect the product's safety and performance.
Comment 2: Different, predicate devices have only a single operation mode. We have designed three modes according to the expected usage scenarios, which are convenient for users to operate according to different tissue types and sizes. The main difference between these three modes is that timing method is countdown or forward timing, foot switch control or manual control, output is continuous or intermittent, these are just to give users more operating options, and do not change the intended use and function of the product, the subject device has been conducted software verification according to the FDA software quidance, the test result proves the functions in each operational mode can be achieved. This difference does not raise a new risk.
All the differences don't affect the safety and effectiveness which is concluded after all the required testing, so no safety and effectiveness issues relating to the system come into conclusion.
### 7. Performance Data
### Clinical test:
Clinical testing is not required.
### Non-clinical data
Microwave Therapeutic System and predicate device are substantially equivalent in design concepts, technologies, which have been designed and tested in accordance with:
### Electrical Safety:
- -ES60601-1 Medical electrical equipment - Part 1: General requirements for basic safety and essential performance (IEC 60601-1:2005, MOD)
Electromagnetic Compatibility:

### 510(k) Summary
- IEC 60601-2-6 Medical electrical equipment Part 2-6: Particular requirements for the basic safety and essential performance of microwave therapy equipment
### Software validation:
- Software validation is in compliance with FDA guidance for the content of premarket submissions for software contained in Medical devices.
#### Shelf Life:
- Accelerated aging tests were conducted to confirm the validity of the 8 years shelf life for l machine.
Thermal Effects test and Temperature monitoring test:
- FDA Guidance Premarket Notification (510(K)) Submissions for Electrosurgical Devices for -General Surgery
### 8. Conclusion
The proposed device is equivalent with respect to the basic system design and function to that of the predicate device. The proposed device isn't the implants and high-risk device. And it doesn't have new intended purposes, new medical, new target populations, and new users and so on. What's more. The differences between the predicate and proposed device do not raise new questions of safety or effectiveness.
