Intended Use

The Cool-tip RF Ablation System E Series (generator, pump, patient return electrodes, water container, active electrodes, footswitch, and accessories) is intended for use in percutaneous, laparoscopic, and intraoperative coagulation and ablation of tissue, including partial or complete ablation of non-resectable liver tumors.

Device Description

The Cool-tip™ RF Ablation System E Series (subject device) is a monopolar radio-frequency (RF) generator (RFAGEN) with dedicated components and accessories. The RFAGEN generator can be operated in one of several modes that use various combinations of time, tissue temperature, tissue impedance, and manual control. An interactive touchscreen display allows user input to the generator and displays informational signals and alert messages. Active electrodes are placed in the tissue to deliver RF energy to the tissue to be ablated. One, two, or three active electrodes can be attached to the generator and can be used individually or as multiple depending on electrode type and mode. A cluster electrodes assembled into one hub in a trianqular pattern can also be used. During the ablation of tissue, RF current flows from the generator to an active electrode which delivers the current to the patient. The RF current flows from the active electrode through the patient's body tissue to the return electrode, which recovers the current and returns it to the generator. The resistance to the current, provided by the patient's tissue, produces the heat that is necessary for ablation of tissue, including partial or complete ablation of non-resectable liver tumors. A peristaltic pump circulates sterile cooling water from an I.V. bag, through active electrodes and into a wastewater container. Cooling water does not contact the patient and is not recirculated. The system does not provide fluids to or remove fluids from the patient.

AI/ML Overview

The provided document is a 510(k) Summary for the Cool-tip™ RF Ablation System E Series. This document focuses on demonstrating substantial equivalence to a predicate device, rather than presenting a study to prove the device meets specific acceptance criteria in the context of AI/ML performance.

Therefore, many of the requested details regarding acceptance criteria, reported device performance, sample sizes, expert qualifications, and ground truth establishment for AI/ML studies are not applicable to this type of regulatory submission. This submission does not involve an AI/ML device that requires performance metrics like sensitivity, specificity, or AUC against a defined ground truth for diagnostic or prognostic purposes.

The document primarily describes:

  • Device Description: The Cool-tip™ RF Ablation System E Series is an electrosurgical cutting and coagulation device, primarily for tissue ablation, including non-resectable liver tumors. It is a monopolar radiofrequency (RF) generator system with dedicated components and accessories.
  • Comparison to Predicate Device: The submission aims to show that the new E Series is substantially equivalent to previously cleared Cool-tip™ RF Ablation System predicate devices, despite some modifications (e.g., combined functionality in the generator, new return electrode, optional accessories).
  • Performance Testing: Non-clinical (bench) and animal testing were conducted to demonstrate equivalence in performance and safety. Clinical studies in human subjects were not required.
  • Regulatory Compliance: The device meets applicable electrical safety, electromagnetic compatibility, usability, software, and biocompatibility standards.

However, to address the prompt as best as possible given the provided text, I will interpret "acceptance criteria" as the regulatory and performance standards the device must meet to achieve substantial equivalence, and "study" as the non-clinical and animal testing conducted.


1. A table of acceptance criteria and the reported device performance

Acceptance Criteria CategoryDescription & StandardReported Device Performance (Summary)
Substantial EquivalenceThe device must demonstrate substantial equivalence to legally marketed predicate devices in terms of intended use, technological characteristics, and safety and effectiveness.The Cool-tip™ RF Ablation System E Series was found to be substantially equivalent to the predicate devices. It relies on the same principles of operation and has similar performance characteristics. The RFAGEN generator combines functionality of the predicate generator and switching controller into a single unit. The subject device has equivalent power and ablation performance characteristics based on verification and validation testing, and pre-clinical studies. The overall conclusion is that it "does not raise different questions of safety and effectiveness."
Electrical Safety & EMCConformity to applicable IEC 60601 safety standards: - IEC 60601-1:2005/AMD1:2012 (General Requirements for Basic Safety and Essential Performance)- IEC 60601-1-2:2014 (4th Edition) (Electromagnetic Disturbances - Requirements and Tests)- IEC 60601-1-6:2010, AMD1:2013 (Usability)- IEC 60601-2-2:2017 (Particular Requirements for the Basic Safety and Essential Performance of High Frequency Surgical Equipment and High Frequency Surgical Accessories)Bench testing and verification conducted. The system was evaluated for electrical safety and electromagnetic compatibility to establish conformity to the identified IEC 60601 standards. The Cool-tip™ E Series RF Ablation System E and optional Cart (FT900RFA) performs as specified within specified storage and use conditions and meets IEC, EMC, regulatory and safety requirements.
Ablation Performance (Bench)The Cool-tip™ E Series RF Ablation Generator must meet all design and performance requirements. Ablation zone dimensions created with the subject device and predicate device must be equivalent. Performance across the complete range of modes, electrodes, and in specified tissue types (liver, kidney, muscle) must be characterized.Laboratory (bench) verification and simulated-use validation testing of soft tissue performance characterized the E Series system ablation performance across the complete range of modes, electrodes, and in three tissue types (liver, kidney, and muscle). It was demonstrated that the Cool-tip™ E Series RF Ablation Generator meets design requirements and that ablation zone dimensions are equivalent to the predicate.
Ablation Performance (Animal)The subject device's histological, thermal, and ablative performance, as well as procedural safety, must be equivalent to the predicate for the Cool-tip™ E Series intended use.In-vivo testing demonstrated the histological, thermal, and ablative performance, as well as procedural safety of the subject device is equivalent to the predicate for the Cool-tip™ E Series intended use.
SoftwareDeveloped in accordance with IEC 62304 (Medical device software life-cycle practices) and FDA Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices with a Major Level of Concern. System level software testing completed successfully.Software for the Cool-tip™ RF Ablation System E Series was developed and system level software testing (version 1.41.01) was completed successfully, adhering to specified standards and guidance.
BiocompatibilityDirect patient contacting devices (patient return electrode, active electrode, remote temperature probe) must be assessed for biocompatibility (Cytotoxicity, Sensitization, Irritation/Intracutaneous Reactivity, Acute Systemic Toxicity, Materials Mediated Pyrogenicity) and determined to be acceptable.The patient contacting materials in the RFAPAD (patient return electrode), Active Electrode, and Remote Temperature Probe (RTP20) were tested to the listed biocompatibility requirements and were determined to be acceptable.
Sterilization & Shelf LifeActive electrode and optional remote temperature probe provided sterile with EtO with SAL of 10^-6^ for RTP20 and 10^-9^ for active electrodes, active electrodes/tubing having a 5-year shelf life, and patient return electrode having a 3-year shelf life. Packaging must provide protection during simulated transportation.The active electrode/tubing are sterilized with EtO to SAL of 10^-9^ and have a 5-year shelf life. The RTP20 is sterilized with EtO to SAL of 10^-6^ and has a 3-year shelf life. The single-use patient return electrode is not sterile and has a 3-year shelf life. Packaging was validated to provide protection during simulated transportation for the RFAGEN, RFAPAD, electrode kits, and Cart.
Accessory CompatibilityPreviously cleared accessories (remote temperature probe and footswitch) must be compatible with the Cool-tip™ E Series Ablation Generator (RFAGEN). New accessories (RFAPAD, RFAPUMP, RFACB cable) must meet design and performance requirements.The previously cleared accessories were found compatible. The new RFAPAD, RFAPUMP, and RFACB cable meet design and performance requirements.

2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

  • Test Set Sample Size: The document does not specify exact "sample sizes" in terms of number of patients or specific ablation procedures for its non-clinical and animal testing.
    • For bench testing, "laboratory (bench) verification and simulated-use validation testing" was conducted across the "complete range of modes, electrodes, and in three tissue types: liver, kidney, and muscle." The extent of this testing (e.g., number of repetitions, specific test configurations) is not detailed.
    • For animal testing, "In-vivo testing" was conducted. The number of animals or specific procedures is not provided.
  • Data Provenance: Not specified in terms of country of origin. The testing was conducted internally or by contracted labs as part of the manufacturer's (Covidien LLC, Boulder, CO) regulatory submission process. The testing for substantial equivalence is inherently prospective in its aim to show the new device performs as expected, but the specific collection protocols for the animal and bench testing are not detailed as retrospective or prospective data collection from broader clinical practices.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

  • Not applicable. This submission is for an RF ablation system hardware and software, not an AI/ML diagnostic or prognostic device that relies on expert interpretation to establish a ground truth for a test set. The "ground truth" here is defined by physical measurements, electrical properties, biological effects observed in animal models, and adherence to engineering and safety standards.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

  • Not applicable. As there is no expert-based ground truth establishment for a diagnostic output, there is no need for an adjudication method. The assessment of equivalence was based on quantitative measurements and observations from bench and animal studies.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

  • Not applicable. This is not an AI-assisted diagnostic or prognostic device designed to improve human reader performance. No MRMC study was conducted.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

  • Not applicable. While the device has software, it is not an AI/ML algorithm intended for standalone diagnostic or prognostic performance. The software controls the RF ablation system's generator and operational modes, and its performance is assessed as part of the overall system's safety and effectiveness, not as an isolated algorithm interpreting medical data.

7. The type of ground truth used (expert concensus, pathology, outcomes data, etc)

  • For the bench testing: The "ground truth" was established by comparing objective physical measurements, electrical performance data, and ablation zone characteristics to pre-defined engineering specifications and to the performance of the predicate device.
  • For the animal testing: The "ground truth" for demonstrating equivalence relied on histological assessment (e.g., cell necrosis, tissue changes), thermal profiles, observed ablative effects, and macroscopic/microscopic evaluation of procedural safety.
  • For regulatory compliance (electrical safety, EMC, biocompatibility, sterilization): Ground truth is established by adherence to recognized national and international consensus standards (e.g., IEC 60601 series, ISO standards for biocompatibility).

8. The sample size for the training set

  • Not applicable. The device is not an AI/ML model that requires a training set in the conventional sense. Its software controls the hardware and operational parameters, which are developed and validated through traditional engineering processes.

9. How the ground truth for the training set was established

  • Not applicable. As there is no AI/ML training set, no ground truth needed to be established for it. The development and verification of the system's software and hardware components followed established medical device design control procedures, where design inputs, specifications, and verification/validation testing define functionality and performance.

6 Intended Use / Indications for Use

The Covidien Cool-tip™ RF Ablation System E Series (generator, pump, patient return electrodes, water container, active electrodes, footswitch, and accessories) is intended for use in percutaneous, laparoscopic, and intraoperative coagulation and ablation of tissue, including partial or complete ablation of non-resectable liver tumors.

{4}------------------------------------------------

6.1 Indication Difference from the Predicate Device

The indication of "osteoid osteoma tumors within bone" has been removed from the subject device.

This change is not critical to the intended therapeutic, prosthetic or surgical use of this device and does not affect the safety and effectiveness of the device when used as labeled.

7. Device Description

The Cool-tip™ RF Ablation System E Series (subject device) is a monopolar radio-frequency (RF) generator (RFAGEN) with dedicated components and accessories. The RFAGEN generator can be operated in one of several modes that use various combinations of time, tissue temperature, tissue impedance, and manual control. An interactive touchscreen display allows user input to the generator and displays informational signals and alert messages. Active electrodes are placed in the tissue to deliver RF energy to the tissue to be ablated. One, two, or three active electrodes can be attached to the generator and can be used individually or as multiple depending on electrode type and mode. A cluster electrodes assembled into one hub in a trianqular pattern can also be used. During the ablation of tissue, RF current flows from the generator to an active electrode which delivers the current to the patient. The RF current flows from the active electrode through the patient's body tissue to the return electrode, which recovers the current and returns it to the generator. The resistance to the current, provided by the patient's tissue, produces the heat that is necessary for ablation of tissue, including partial or complete ablation of non-resectable liver tumors.

A peristaltic pump circulates sterile cooling water from an I.V. bag, through active electrodes and into a wastewater container. Cooling water does not contact the patient and is not recirculated. The system does not provide fluids to or remove fluids from the patient.

The dedicated system components include:

  • o RF Generator (RFAGEN), radio frequency generator
  • RF Ablation Pump (RFAPUMP), peristaltic pump for circulating cooling water ●
  • . RF Ablation Connector Bank (RFACB) cable for connecting return electrodes to the generator
  • Ablation Foot Switch (RFASW), generator footswitch ●
  • Ablation Water Container (RFAWC), wastewater collection container ●

The RFAGEN generator is packaged individually and is always supplied with the accessory kit RFAPAC (separately packaged) which contains items RFAPUMP, RFACB, RFASW, and RFAWC.

The following Cool-tip™ RF Ablation System E Series compatible accessories are single use:

  • RF Ablation Single Electrode Kits E Series (RFAXXX), RF Ablation Multiple Electrode ● Kits E Series (RFAXXXX), and RF Ablation Cluster Electrode Kits E Series (RFACXXXX)
  • RF Ablation Patient Return Electrode E Series (RFAPAD) ●
  • Ablation Remote Temperature Probe (RTP20) (optional) ●

The Cool-tip™ RF Ablation System E Series can be mounted on an optional system cart FT900RFA with the FT3X cart kit that has locations for each system component.

8. Comparison of Technological Characteristics with the Predicate Device

The Cool-tip™ RF Ablation System E Series (subject device) relies on the same principles of operation and has similar performance characteristics, with respect to its intended use, as the predicate devices. The Cool-tip™ RF Ablation System E Series combines the functional characteristics of the predicate Cool-tip™ generator (K052796) and the Cool-tip™ Switching Controller (K070446).

{5}------------------------------------------------

There are three main differences between the Cool-tip™ RF Ablation System E Series and the predicate Cool-tip™ RF Ablation System

    1. A new larger patient return electrode (RFAPAD) allowing for two return electrodes for ablations where four electrodes are required for the predicate device. The return electrode connector bank (RFACB) is a new dedicated reusable extension cable that connects the patient return electrodes to the generator.
    1. The RFAGEN generator combines the functional characteristics of both the predicate Cooltip™ generator and the Cool-tip™ Switching Controller into a single RF generator that includes an updated user interface and software controls.
    1. The addition of several optional accessories, specifically, a footswitch, remote temperature probe and system cart.

Like the predicate device, the Cool-tip™ RF Ablation E Series System has three categories of Cooltip ™ RF Ablation electrodes. The categories are single, multiple and cluster electrodes. The Cooltip™ E Series active electrodes deliver RF energy from the Cool-tip™ E Series generator for the ablation of tissue when used with the Cool-tip™ E Series Pump, Inflow and Outflow Tubing Sets, and RFAPAD Patient Return Electrodes. All Cool-tip™ RF Ablation E Series are provided in kits containing sterile active electrodes, sterile tubing for electrode cooling fluid, and patient return electrodes. Electrode Kits with single, multiple and cluster active electrodes are available. All kit items are single use.
