The document describes a standard RF ablation system with a console, user interface, and ablation needle. There is no mention of AI, ML, image processing, or any data-driven decision-making components. The performance studies focus on electrical safety, biocompatibility, and ablation characteristics, not on the performance of any AI/ML algorithms.
Yes
The device is intended for the coagulation and ablation of soft tissue, which are therapeutic interventions.
No
Explanation: The device is intended for the coagulation and ablation of soft tissue, which are therapeutic procedures. It does not perform any diagnostic function.
No
The device description clearly lists multiple hardware components including a console, user interface, ablation needle, syringe, and return electrode pads and cables. While software is mentioned as being validated, it is part of a larger hardware system.
Based on the provided information, the SERF Ablation System is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use is for the coagulation and ablation of soft tissue during surgical procedures (percutaneous, laparoscopic, and intraoperative). This is a therapeutic and surgical intervention performed directly on the patient's body.
- Device Description: The device description details a system that delivers heat (RF energy and warm saline) to tissue within the body for thermal necrosis. It involves a console, user interface, and a needle that penetrates tissue.
- Lack of In Vitro Activity: There is no mention of the device being used to examine specimens (blood, urine, tissue samples, etc.) outside of the body to provide diagnostic information.
IVD devices are specifically designed to perform tests on samples taken from the human body to provide information for the diagnosis, monitoring, or treatment of a disease or condition. The SERF Ablation System is a therapeutic device used to treat tissue directly within the body.

Device Description
The SERF Ablation System and SERF Ablation Needle provide heat to unwanted tissue targeted for ablation and thermal necrosis. The SERF System has these main components:
-
- SERF Ablation System console which houses the RF generators, fluid pump, and system user interface. The system is designed to comply with Electrical Safety (IEC60601-1), Electromagnetic Compatibility (IEC60601-1-2), and Particular Requirements for the Safety of High Frequency Surgical Equipment (IEC60601-2-2). Product testing was conducted to evaluate conformance to product specifications. Software is validated.
-
- System user interface, an alphanumeric display for menus and messages and a control panel which displays the set-point of each parameter of the therapy.
-
- SERF Ablation Needle, a single-use, sterile device intended to penetrate tissue to locate the point of therapy initiation based on visual guidance. The SERF Needle is electrically connected to the system and delivers RF energy and warm saline to the tissue through perforations in the shaft near the needle tip. All patient contacting materials are commonly used and have been tested for biocompatibility in this application.
-
- A sterile single-use syringe for use with the SERF system is commercially available. The syringe mounts on the pump and delivers sterile saline through a fluid delivery tube to the Ablation Needle.
-
- Return electrode pads and cables for use with the SERF System are commercially available, The SERF system is a monopolar electrosurgical device. The RF circuit is closed through a return path including the return electrode pads which are plugged into the SERF system.
The System is programmed for the desired power level, and procedure time by the operator. Saline infusion rate and target saline temperature are also programmed. The system controls power by monitoring the voltage and current.

Substantial Equivalence
The SERF Ablation System has the same intended use and indications for use as other previously 510(k) cleared RF ablation systems. The technological characteristics of the SERF Ablation System are also substantially similar to other previously cleared ablation systems. Although there are minor differences in technological characteristics between the SERF Ablation System and the predicates, these differences do not raise any new types of safety or effectiveness issues.
The SERF Ablation System is compared with the Covidien™ Cool-Tip™ and the AngioDynamics™ RITA™ predicate devices. Comparison of intended use, technological features, the therapy applicator, the control methodology, and the resulting ablative lession demonstrates equivalence as confirmed by performance testing.

Dear Ms. Hogan:
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 (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. 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.
