ON-Q* Pump is intended to provide continuous delivery of medication (such as local anesthetics) to or around surgical wound sites and/or close proximity to nerves for preoperative and postoperative regional anesthesia and/or pain management. Routes of administration include: intraoperative site, peripheral nerve block, percutaneous and epidural.
ON-Q* Pump is indicated to significantly decrease pain and narcotic use when used to deliver local anesthetics to or around surgical wound sites, or close proximity to nerves, when compared to narcotic only pain management.
ON-Q* Pump with Bolus device is intended for users 18 years of age and older.
The ON-Q* Pump with Bolus consists of an elastomeric pressure source (i.e. elastomeric pump) with an integrated administration set/line. The ON-Q* Pump with Bolus delivers continuous infusion (basal) and allows incremental fixedvolume boluses to be delivered on demand by the patient. In addition to the optional bolus component, the administration line may contain any of the following optional components:
- Filter
- Select-A-Flow variable flow rate assembly ●
- Y-adaptor ●
The bolus component controls the bolus and/or basal flow rate capability of the administration set that connects to the elastomeric pump. The bolus component is an integrated part of the pump system and cannot be used alone. The patient or healthcare provider presses a button to activate bolus delivery. The refill time determines the patient must wait prior to receiving another full bolus dose.

The COOLIEF* Cooled Radiofrequency Probe is to be used in conjunction with a radiofrequency generator to create lesions in nervous tissue. This device is also indicated for creating radiofrequency lesions of the genicular nerves for the management of moderate to severe knee pain of more than 6 months with conservative therapy, including medication, in patients with radiologically-confirmed osteoarthritis (grade 2-4) and a positive response (≥50% reduction in pain) to a diagnostic genicular nerve block.
The COOLIEF* Cooled Radiofrequency (RF) Probe is a sterile, single-use device that delivers RF energy within the area of the active probe tip, while the probe tip is cooled by sterile water that circulates within the probe. Cooling the probe tip creates a larger. more homogenous RF heating area that results in a larger RF lesion in the target tissue. COOLIEF* Cooled RF Probe is used in conjunction with the Halyard RF Generator to create RF lesions in nervous tissue. The shaft of the probe is insulated with a polyimide sheath, and the distal tip consists of a medical grade stainless steel electrode. Sterile water circulates through a cavity in the electrode to cool the electrode tip during the cooled RF ablation procedure. The COOLIEF* Cooled Radiofrequency (RF) Probe is sterilized by ethylene oxide.
Here's an analysis of the acceptance criteria and the study that proves the device meets them, based on the provided text:
Acceptance Criteria and Device Performance
1. Table of Acceptance Criteria and Reported Device Performance
The document doesn't explicitly state "acceptance criteria" in a singular section for clinical performance. Instead, it describes the effectiveness endpoint and provides the results.
| Characteristic / Test Type | Acceptance Criteria (Implied) | Reported Device Performance (COOLIEF* Cooled RF Probe) |
|---|---|---|
| Clinical Effectiveness (Primary Endpoint) | Superiority to corticosteroid injection in achieving ≥ 50% pain reduction at 6 months post-treatment in patients with moderate to severe knee pain due to radiologically-confirmed osteoarthritis (grade 2-4) and a positive response (≥50% reduction in pain) to a diagnostic genicular nerve block. | 67.2% of the COOLIEF* Cooled RF study group achieved ≥50% pain relief at 6 months, compared to 15.7% of the corticosteroid injection group (p-value for superiority not explicitly stated but implied by "superior to steroid injection").Mean NRS pain reduction: 4.9 points (from 7.3 to 2.5) at 6 months.Significant functional improvement: 39.7% reported "Satisfactory Joint Function" vs. 3% in comparison group.Global Perceived Effect: 91.4% reported "improved" knee condition vs. 23.9% in comparison group. |
| Cytotoxicity | Qualitative Grade = 0; Quantitative = cell death < 30% | Pass: No Cytotoxic effect |
| Sensitization | Challenge Phase = Less than Grade 1 and less than the controls | Pass: No signs of sensitization |
| Irritation or Intracutaneous Reactivity | Test sample score < 1.0 for Erythema and Edema grading | Pass: No signs of Irritation |
| Systemic Toxicity (acute) | No animal death | Pass: No signs of systemic toxicity |
| Electrical Safety | Conformance to IEC 60601-1:2005 | Passed |
| High Frequency Surgical Equipment | Conformance to IEC 60601-2-2: 2009 (Fifth Ed.) | Passed |
| Electromagnetic Compatibility (EMC) | Conformance to IEC 60601-1-2:2007 / AC 2010 | Passed |
2. Sample Size Used for the Test Set and Data Provenance
- Clinical Study Test Set Sample Size: The document indicates an Intent-to-Treat (ITT) population for the primary effectiveness endpoint.
- COOLIEF* Cooled RF (CRFA) group: 76 subjects
- Corticosteroid Injection (IAS) group: 75 subjects
- Data Provenance: The clinical study was a prospective, multicenter, randomized comparative human study. The document does not specify the country of origin, but given the FDA submission, it's typically a US-based or international study adhering to US regulatory standards.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications
This question is not applicable in the context of this device and study. The "ground truth" for the clinical study was based on patient-reported outcomes (Numeric Rating Scale for pain, "Satisfactory Joint Function" report, Global Perceived Effect) and a diagnostic genicular nerve block response for patient selection, not expert consensus on images or pathology.
4. Adjudication Method for the Test Set
Adjudication methods (like 2+1, 3+1) are typically used in studies where subjective assessments (e.g., image interpretation) need to be resolved. This clinical study focused on patient-reported outcomes and objective measures (like pain scale changes), so a formal adjudication method as commonly understood in imaging studies would not be directly applicable. The "ground truth" was directly from the patient or objective measurements.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was Done
No, an MRMC comparative effectiveness study was not done. The study was a randomized controlled trial comparing the device (COOLIEF Cooled RF Probe) to a control treatment (corticosteroid injection)* for pain management in patients, not a study evaluating human readers' performance with and without an AI algorithm.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was Done
This is not an AI/algorithm-based device. The COOLIEF* Cooled RF Probe is a medical device that physically delivers radiofrequency energy. Therefore, the concept of a "standalone algorithm performance" does not apply. The study evaluated the device's therapeutic effect.
7. The Type of Ground Truth Used (expert consensus, pathology, outcomes data, etc.)
The primary ground truth for the clinical effectiveness study was:
- Outcomes Data (Patient-Reported Outcomes): Numeric Rating Scale (NRS) for pain reduction, patient reports of "Satisfactory Joint Function," and Global Perceived Effect of knee condition.
- Diagnostic Response: Patients were selected based on a positive response (≥50% reduction in pain) to a diagnostic genicular nerve block, serving as an inclusion criterion rather than a "ground truth" for the clinical outcome itself.
For the non-clinical tests, the ground truth was derived from established scientific and regulatory standards (e.g., ISO guidelines) and laboratory measurements (e.g., cell death percentage for cytotoxicity, animal responses for sensitization/irritation/toxicity).
8. The Sample Size for the Training Set
This is not an AI/machine learning device, so there is no "training set" in the conventional sense for an algorithm. The clinical study was a prospective comparative trial to evaluate the device's performance directly on human subjects.
9. How the Ground Truth for the Training Set Was Established
As noted above, there is no "training set" for an algorithm. The clinical data was collected from the prospective human study to directly assess the safety and effectiveness of the device.

The HALYARD* COOLIEF* Cooled Radiofrequency Kit, in combination with the HALYARD* Radiofrequency (RF) Generator (PMG-BASIC/PMG-ADVANCED) (formerly Baylis Pain Management Generator or KIMBERLY-CLARK® Pain Management Generator) is intended for the creation of Radio-Frequency (RF) heat lesions in nervous tissue for the relief of pain, and includes a fluid delivery system for commonly used fluid agents limited to contrast medium, saline, and/or anesthetic solution delivery at the target site.
The COOLIEF* Cooled Radiofrequency (RF) Kit is similar in construction, materials, energy source, and intended use to the predicate TransDiscal Cooled Radiofrequency Kit, which is a part of the cleared TransDiscal System (K062937) that also includes a "Y connector cable for the probes, a cooling pump, and a pump connector cable that connects to the RF generator. The COOLIEF* Cooled RF Kit includes fluid delivery introducers, cooled probes, and a burette tubing assembly. The subject COOLIEF* Cooled Radiofrequency Kit is available in several configurations based on the anatomic region of use (i.e., available in various introducer and probe lengths, and active tip lengths). The kit is sterilized to a SAL of 10-6 by EO terminal sterilization. The Fluid Delivery Introducer is a sterile, non-pyrogenic single-use cannula with a fluid delivery port. It is used with cooled radiofrequency probes in conjunction with the Halyard Radiofrequency Pain Management Generator, with cooling pump, to create lesions in nervous tissue for the relief of pain.
This document is a 510(k) Pre-Market Notification for the HALYARD* COOLIEF* Cooled Radiofrequency Kit, and as such, it focuses on demonstrating substantial equivalence to a predicate device rather than providing a detailed study proving the new device meets specific acceptance criteria in the way a clinical trial or algorithm validation study would.
The information provided describes the device, its intended use, and comparisons to a predicate device (TransDiscal Cooled RF Kit, K062937) and a reference device (Diros OWL Sterile Single-Use Trident R.F. Insulated Cannula models DTR and DTRH, K150371). The "acceptance criteria" here are implicitly the standards and features of the predicate device and the relevant biocompatibility and mechanical test standards.
Here's an analysis of the provided text in the context of your request:
1. A table of acceptance criteria and the reported device performance

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
The document primarily describes non-clinical (bench) testing. For such tests, "sample size" refers to the number of units tested for mechanical properties, biocompatibility, etc. This specific numerical sample size is not explicitly provided in the summary for individual tests (e.g., how many cannulas were tested for bond strength). The data provenance is from internal testing conducted by the manufacturer (Halyard Health, Inc.), implicitly in the USA. These are prospective tests conducted on the newly designed device components.
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)
This section is not applicable. The "ground truth" concept is typically relevant for diagnostic or AI-based devices where human expert interpretation is compared to device output. For a physical medical device like a radiofrequency kit, performance is evaluated against engineering specifications, material standards, and functional tests, not against expert-established ground truth in a clinical sense.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
This section is not applicable for the reasons stated above (non-clinical testing of a physical device).
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
This section is not applicable. An MRMC study is relevant for diagnostic imaging devices or AI tools involving human interpretation. This submission is for a therapeutic radiofrequency ablation kit.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
This section is not applicable. This is not an AI algorithm. The device performance is the physical device's ability to create lesions and deliver fluids, which is tested directly.
7. The type of ground truth used (expert concensus, pathology, outcomes data, etc)
As mentioned, true "ground truth" as typically defined for AI or diagnostic devices is not applicable. The "ground truth" for this device's performance validation is its adherence to:
- Established ISO standards for biocompatibility and mechanical properties.
- Functional requirements (e.g., fluid flow, lesion size in a tissue model).
- Equivalence to the predicate device's known performance.
8. The sample size for the training set
This section is not applicable. There is no "training set" as this is not an AI/machine learning device. The device is validated through engineering and bench testing, not through training on data.
9. How the ground truth for the training set was established
This section is not applicable for the reasons stated above.

The EZstim*III is a battery powered Peripheral Nerve Stimulator/Nerve Locator with two (2) indications for use:
(1) on the high (0.05 - 80 mA) output current range, the device is used to monitor the effects of skeletal muscle relaxants during general anesthesia.
(2) on the low (0.05-5.0 mA) output current range, it is used as a Nerve Locator to help locate the tip of a hypodermic needle near the nerve to which local anesthesia is to be delivered in Regional Nerve Block procedures.
The EZstim* III (Model ES500) is both a constant current Peripheral Nerve Stimulator (HIGH output current range) and a Peripheral Nerve Locator (LOW output current range). Output current range is determined by the model of patient lead cable connected to the unit.
- . When the Halyard NSL-5 patient lead cable is connected, the unit automatically sets to the HIGH output current range (0.05 to 80 mA), with no stimulus mode selected (null mode). When the user selects a stimulus mode (i.e., 1 or 2 Hz Twitch, 50 Hz Tetanus, 100 Hz Tetanus, Double-Burst, or Train-of-Four), the unit functions as a nerve stimulator for use in monitoring the effects of skeletal muscle relaxants on the neuromuscular junction.
- . When the Halyard RBW-5U patient lead cable is connected, the unit automatically sets to the LOW output current range (0.05 to 5.0 mA). In this range, the unit functions as a nerve locator for use in regional nerve block procedures.
The provided documentation describes the Halyard Health EZstim* III Peripheral Nerve Stimulator/Nerve Locator (Model ES500), which is a medical device. This device is not an AI/ML device, therefore, many of the requested criteria are not applicable.
Here's an analysis of the acceptance criteria and study information provided for this medical device, tailored to what is available in the document:
1. Table of Acceptance Criteria and Reported Device Performance
| Test Name and Description | Acceptance Criteria (Implied) | Reported Device Performance |
|---|---|---|
| IEC 60601 Safety Testing (Electrostatic Discharge, Radiated Immunity, Conducted RD Immunity, Magnetic Field Immunity, Radiated Emissions, Immunity to proximity field from RF wireless communication equipment, Conducted Disturbances Induced by RF Fields Immunity, Power Frequency Magnetic Fields Immunity, Leakage Current, Dielectric Voltage Withstand, Excessive Temperature, Humidity Preconditioning, Abnormal Operation and Fault Conditions) | Compliance with IEC 60601-1 (3.1 Edition) and IEC 60601-1-2 (4th Edition) | Pass |
| Software Verification (Validation in accordance with FDA Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices (May 11, 2005)) | Software meets design requirements | Pass |
| Hardware Verification (Output current test, Beeper test, Battery removal test, Weight test, Internal temperature test) | Hardware and Software system functions as intended and design outputs meet design input | Pass |
| Packaging Verification (Distribution simulation testing per ASTM D4169-14: Temperature and Humidity Conditioning, Schedule A - Manual Handling (First Drop Sequence), Schedule C - Vehicle Stacking, Schedule F - Loose Load Vibration, Schedule E - Vehicle Vibration, Schedule J - Concentrated Impact, Schedule A – Manual Handling (Second Drop Sequence)) | Packaging maintains integrity during distribution simulation | Pass |
| Electrosurgery Test (Ensures device is electrosurgery compatible and operates as intended in High Output Current mode) | Device operates as intended in High Output Current mode during electrosurgery | Pass |
| Battery Life Test (Ensures duration of single 9V battery functions in accordance with established acceptance criteria for the ES500 device) | Battery life meets design input requirement | Pass |
| Battery Door Seal Integrity (Adhesive) Test (Ensures adhesive gasket in the battery door compartment maintains integrity after battery replacements) | Adhesive gasket maintains integrity after battery replacements | Pass |
2. Sample Size Used for the Test Set and Data Provenance
The document does not specify exact sample sizes for each test mentioned (e.g., number of devices tested for EMC, number of software modules tested). It generally states that "testing of the EZstim* III Peripheral Nerve Stimulator/Nerve Locator was performed."
- Data Provenance: The tests are non-clinical (laboratory-based) and conducted to demonstrate compliance with recognized standards and internal design requirements. They are presumably prospective in the sense that the tests were designed and executed specifically for this device submission. The country of origin of the data is not specified but is implicitly from the manufacturer's testing facilities or accredited test labs.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications
- This question is not applicable as the device is a hardware medical device, and the evaluation relies on engineering and regulatory compliance testing rather than expert-derived ground truth as would be used for AI/ML diagnostic devices.
4. Adjudication Method for the Test Set
- This question is not applicable. Adjudication methods like 2+1 or 3+1 are typically used in clinical studies involving human readers or expert consensus, which are not relevant to the non-clinical engineering and regulatory compliance tests performed for this device.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
- This question is not applicable. An MRMC study is relevant for AI/ML diagnostic tools that assist human readers in interpreting medical images or data. The EZstim* III is a peripheral nerve stimulator/locator, a hardware device with a direct physiological function, not an interpretative AI. No human reader assistance is involved in its direct function.
6. Standalone (Algorithm Only) Performance
- This question is not applicable. The device is not an algorithm; it is a physical hardware device with embedded software. The software verification test (mentioned in the table) assesses the software's functionality as part of the overall device system, but there is no "standalone algorithm" performance assessed separately from the device's hardware.
7. Type of Ground Truth Used
- The "ground truth" for the tests performed is based on engineering specifications, recognized international standards (IEC 60601-1, IEC 60601-1-2, ASTM D4169-14), and internal design input requirements. These are objective, measurable performance benchmarks rather than expert consensus, pathology, or outcomes data, which are typically used for diagnostic or predictive AI/ML models.
8. Sample Size for the Training Set
- This question is not applicable. The device is not an AI/ML algorithm that undergoes a "training phase." The "training set" concept is not relevant to its development and testing.
9. How the Ground Truth for the Training Set Was Established
- This question is not applicable for the same reason as point 8.

The Aero Chrome* Breathable Performance Surgical Gowns are also sold as bulk non-sterile, single use items, to repackager/relabeler establishments for further packaging and Ethylene Oxide (EtO) sterilization
The Aero Chrome* Breathable Performance Surgical Gowns have a Spunbond/Film/Spunbond/Meltblown/Spunbond design (SFSMS) that provides AAMI Level 4 liquid barrier protection in the critical zones of the gown. The back of the Aero Chrome* Breathable Performance Surgical Gown in the non-critical zone has a SMS Spunbond/meltblown/spunbond) fabric that is air-breathable and provides AAMI Level 1 liquid barrier protection. The Aero Chrome* Breathable Performance Surgical Gowns are single use, disposable medical device that will be provided in a variety of sterile and non-sterile packaging configurations described below.
The provided document is a 510(k) premarket notification for a medical device: the Aero Chrome Breathable Performance Surgical Gown*. This type of submission focuses on demonstrating substantial equivalence to an already legally marketed predicate device, rather than proving novel efficacy or safety through primary clinical trials for the device itself. Therefore, the "study" proving the device meets acceptance criteria primarily consists of non-clinical performance testing to show that the new device performs at least as well as, or equivalently to, the predicate device in relevant aspects.
Here's an analysis of the acceptance criteria and the provided information:
1. A table of acceptance criteria and the reported device performance:
The document doesn't present a single consolidated "acceptance criteria" table as one might find for a diagnostic AI device with precision/recall metrics. Instead, it details various performance tests demonstrating compliance with recognized standards for surgical gowns. The acceptance criteria for each test are implicitly (or explicitly, as "Pass") stated as meeting the requirements of the specified standard.
| Acceptance Criteria (Standard & Level) | Test Method | Reported Device Performance (Aero Chrome*) |
|---|---|---|
| AAMI PB70:2012 Liquid Barrier Classifications | Resistance to Penetration by Blood-Borne Pathogens Using Phi-X174 Bacteriophage (Level 4) | Pass |
| Water resistance (Level 1 in non-critical zones) | Pass | |
| 16 CFR 1610 (Flammability) | Flammability | Pass (Class I) |
| ISO 10993-5:2009 (Biological Evaluation) | Cytotoxicity | Pass (non-cytotoxic) |
| ISO 10993-10:2010 (Biological Evaluation) | Skin Irritation Study | Pass (negligible irritant) |
| Sensitization Test | Pass (non-sensitizing) | |
| ISO 10993-7:2008 (EO Sterilization) | EO residuals | Pass |

| STM-00197 (2010) (Peel Strength) | Peel Strength | Pass |
| INDA WSP 160.1 (2009) (Linting) | Particulate | Pass |
2. Sample size used for the test set and the data provenance:
- Sample Size: The document does not specify the exact sample sizes used for each individual non-clinical performance test. Standard test methods (e.g., ASTM, ISO, AAMI) typically define the minimum sample sizes required for statistically valid testing. For example, for textile testing (tensile strength, abrasion), there would be a specified number of specimens. For biocompatibility (cytotoxicity, irritation, sensitization), there would be a defined number of replicates and control groups.
- Data Provenance: The data comes from the manufacturer's (Halyard Health, Inc.) own non-clinical performance testing. It is not explicitly stated if these were internal labs or third-party labs, but generally, such tests are conducted in controlled lab environments. The document does not specify a country of origin for the data; it's implicit to be associated with Halyard Health's operations for regulatory submission in the US.
- Retrospective or Prospective: These are prospective tests performed specifically to demonstrate that the newly designed Aero Chrome* gown meets the required performance standards for its intended use and for comparison with the predicate device.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- This question is not applicable in the context of this device and submission. This is a surgical gown, not an AI/diagnostic device that relies on expert interpretation of images or patient data to establish ground truth. The "ground truth" for a surgical gown's performance is established by objective, measurable physical, chemical, and biological properties, as defined by recognized consensus standards (e.g., AAMI, ISO, ASTM). The expertise lies in conducting the tests according to the standard protocols and interpreting the quantitative results against the specified pass/fail criteria.
4. Adjudication method for the test set:
- This question is not applicable. Since the "ground truth" is established through objective laboratory testing against predefined standards (e.g., a specific resistance value, a pass/fail for bacterial penetration), there is no human "adjudication" in the sense of multiple readers or experts reviewing subjective data. The test results are quantitative/qualitative outcomes of physical/chemical processes.
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:
- This question is not applicable. This is a physical medical device (surgical gown), not an AI diagnostic algorithm. Therefore, MRMC studies and AI assistance are irrelevant to its evaluation.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- This question is not applicable. This is a physical medical device, not an algorithm.
7. The type of ground truth used:
- The ground truth for this device's performance is established by objective, quantitative measurements and qualitative assessments derived from standardized laboratory test methods (e.g., AAMI PB70:2012, ASTM D5034, ISO 10993 series). These standards define specific criteria (e.g., pressure resistance, microbial penetration, tensile strength limits, cytotoxicity levels) that the device must meet. It is not based on expert consensus, pathology, or outcomes data in the way a diagnostic tool would be.
8. The sample size for the training set:
- This question is not applicable. This is a physical device, and there is no "training set" in the context of machine learning. The manufacturing process of surgical gowns involves material selection, design, and fabrication, which are validated through process controls and quality assurance, not through a "training set" of data.
9. How the ground truth for the training set was established:
- This question is not applicable for the reasons stated above.
In summary: The submission for the Aero Chrome* Breathable Performance Surgical Gown focuses on demonstrating substantial equivalence to a predicate device (Aero Blue* Performance Surgical Gown) by providing comprehensive non-clinical performance test results against established industry standards. The "acceptance criteria" are the "Pass" outcomes for each of these standardized tests, indicating that the gown meets the specified physical, chemical, and biological performance requirements relevant to its intended use as protective apparel. The evaluation does not involve clinical studies with human "readers" or AI algorithms.
