Intended Use
The Temperature Sensor Probe, used with Varian ablation systems, is intended for monitoring tissue temperature near the ablation site.
Device Story
Temperature Sensor Probe is an optional, single-use, disposable accessory for Varian microwave ablation systems. It consists of a needle with a T-type thermocouple at the tip, a handle containing a PCBA, and a lead cable. The device is inserted into tissue near the ablation site by a clinician; the thermocouple measures tissue temperature in real-time. The handle's PCBA converts analog temperature signals to digital, which are then transmitted to the ablation system console for continuous display. This real-time monitoring allows clinicians to observe temperature changes during ablation, potentially aiding in procedure control. The device is rigid, 18G, and 20cm in length, featuring a trocar tip that eliminates the need for a separate cannula and stylet used in predicate designs.
Clinical Evidence
No clinical data or testing included. Performance validated via non-clinical bench testing (accuracy, reliability, functional support) and porcine soft tissue animal models. Biocompatibility evaluated per ISO 10993-1; electrical safety/EMC per IEC 60601 series; sterilization per ISO 11135.
Technological Characteristics
Materials: Stainless steel (needle), ABS (handle), PVC (cable jacket). Sensing: T-type thermocouple. Form factor: 18G, 20cm rigid needle with trocar tip. Connectivity: Wired to ablation system console. Sterilization: 100% ethylene oxide. Standards: ISO 10993-1, ISO 11135, IEC 60601-1, IEC 60601-1-2, IEC 60601-1-6, IEC 60601-2-6.
Indications for Use
Indicated for monitoring tissue temperature near the ablation site during ablation procedures using Varian ablation systems. Not intended for cardiac procedures.
Regulatory Classification
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.

Dear Lynn Allman:
We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm____identifies ____combination_ product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

### Performance Data: VII.
## 1. Non-clinical Testing:
Temperature Sensor Probe underwent non-clinical testing to demonstrate the design and performance of the device meets the established design criteria. The subject device successfully completed functional intended use support and reliability testing. To support substantial equivalence in performance with the predicate device, the subject and predicate devices underwent side-by-side testing for performance i.e accuracy of temperature monitoring. The test results established that the subject device is substantially equivalent to the predicate device in performance and is as safe and effective as the predicate device.
### 2. Non-clinical Animal Testing:
Animal testing completed with Temperature Sensor Probe to validate usability and performance of the device on porcine soft tissue models complies with the United States Food and Drug Administration Good Laboratory Practice (GLP) Regulations, 21 CFR Part 58.
### 3. Clinical Data/ Testing:
No clinical data/ testing is included within the submission.
