2. Sample Size Used for the Test Set and Data Provenance
The document does not explicitly state the numerical sample size for individual tests. However, it indicates that "Biocompatibility and sterility testing has been conducted on the 25ga Adjustable Chandelier Illuminators as a 'worst case device' and a family representative." This suggests a limited sample size, focusing on one representative (25ga).
The data provenance is internal, originating from Peregrine Surgical Ltd. It is retrospective, as these are bench tests conducted to support a premarket submission. No information about the country of origin of the data is provided beyond the company's location (New Britain, PA, USA).
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
Not applicable. This device is not an AI/ML diagnostic or prognostic tool that requires expert-established ground truth on a test set. The tests performed are bench tests evaluating physical and functional characteristics of a medical illuminator. The "ground truth" for these tests would be the established standards and specifications outlined in the referenced ISO and ASTM methods, or the company's internal test protocol specifications.
4. Adjudication Method for the Test Set
Not applicable, as this is not a diagnostic assessment requiring adjudication among experts. The tests are objective measurements against defined standards.
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/ML device, and no MRMC study was performed.
6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This is not an AI/ML device. The "standalone" performance refers to the device's functional characteristics as an illuminator, which were assessed through the listed bench tests.
7. The Type of Ground Truth Used (expert consensus, pathology, outcomes data, etc.)
The "ground truth" for the non-clinical performance data is the defined acceptance criteria and specifications within the referenced ISO, ASTM, and Internal Test Methods. For example:
- Sterility: The device must meet the sterility assurance level (SAL) specified in ISO 11135-1.
- Biocompatibility: The device materials must meet the biological safety requirements outlined in ISO 10993-01.
- Light Output: The device's light output must meet the specified lumen value (3.7 lumen, as indicated in Table 5.2).

PEREGRINE SURGICAL, LTD.
For photocoagulation and illumination during ophthalmic surgery. This device delivers illumination as well as laser energy to target tissue, causing coagulation. Spot size can be varied by altering the distance between the tissue and the probe tip.
Peregrine's 25ga Curved Illuminating Laser Probe is an ophthalmic light and laser delivery device. It consists of glass fiber with PVC jacket, an SMA connector, a Delrin handpiece and a needle set consisting of 304 stainless steel and nitinol. There is also an actylic fiber with PVC jacket and an aluminum illumination connector. Both connectors plug into existing laser and light sources.
The Laser Probe can only be used in combination with a medical laser in the Vis-NIR transmission range of 532nm to 810mm with a maximum power output of 2.5 Watts and that is appropriate for photocoagulation. The light portion of the device is designed for use with the Alcon Constellation Vision System. The Constellation uses a 50 Watt Xenon arc lamp that emits light with an output of 30 lumens within the wavelength range of 400nm to 700mm.
The outer dimension of the glass fiber to be used in the proposed device is 98 microns or about .004 inches, which is about 25% of the size of the glass fiber in Peregrine's predicate device.
The acrylic fiber that will be used has an outer dimension of 254 microns or .01 inches, which is 25% of the size of the acrylic fiber used in the predicate device. The decrease in size of both fibers has created an acceptable device.
Here's a breakdown of the acceptance criteria and study information for the Peregrine 25ga Curved Illuminating Laser Probe, based on the provided text:

2. Sample size used for the test set and the data provenance
The document does not explicitly state a "test set" in the context of human data or a specific number of devices tested for each performance characteristic. Instead, it refers to:
- "3 performance tests" to evaluate light output, laser power output, and laser field clarity. The sample size for these tests is not specified.
- "Bend testing" performed on both the existing and proposed designs. The number of samples for bend testing is not specified.
- Biocompatibility testing. The number of material samples tested is not specified.
- Sterilization and shelf-life validation. This would involve a specific number of packages/devices, but the exact count is not given.
The data provenance is Peregrine Surgical Ltd. internal testing. The document does not specify country of origin for test data, nor does it explicitly state if it was retrospective or prospective, though performance and material testing are typically prospective.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
Not applicable. The document describes engineering and material performance testing rather than studies involving expert human review of medical images or diagnoses. The "ground truth" here is based on measurable physical properties and compliance with established material and manufacturing standards.
4. Adjudication method for the test set
Not applicable. This type of adjudication (e.g., 2+1, 3+1) is relevant for studies where human experts interpret data (like images) and resolve discrepancies. The provided document details technical performance and material testing.
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 device is a surgical tool (laser probe), not an AI-powered diagnostic or assistive tool for human readers. Therefore, an MRMC study and AI assistance are not relevant to its evaluation.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Yes, in essence, standalone performance tests were done. The "3 performance tests" (light output, laser power output, laser field clarity), "bend testing," and biocompatibility testing represent the standalone performance evaluation of the device itself, without human interpretation in a diagnostic context. The device's function is to transmit laser and light energy, and these tests evaluate that function directly.
7. The type of ground truth used
The ground truth used for this device's evaluation is primarily based on:
- Physical measurements and engineering specifications: Metrics like laser power efficiency, spot size, fiber dimensions, length, weight, etc., are directly measured and compared against the predicate device's established performance parameters.
- Material standards: Biocompatibility is assessed against established biological safety standards. Nitinol's use is justified by its existing approval in other ophthalmic devices and by specific bend testing.
- Sterilization and shelf-life validation standards: Compliance with AAMI Overkill Method according to ISO 11135-1 and residual testing.
8. The sample size for the training set
Not applicable. This device's development and evaluation do not involve machine learning or AI, so there is no "training set."
9. How the ground truth for the training set was established
Not applicable. As there is no training set, this question is not relevant.

For photocoagulation and illumination during ophthalmic surgery. This device delivers illumination as well as laser energy to target tissue, causing coagulation. Spot size can be varied by altering the distance between the tissue and the probe tip.
The 23ga Curved Illuminating Laser Probe is an ophthalmic light and laser delivery device. It consists of glass fiber with PVC jacket, an SMA connector, an acetal handpiece and a needle set consisting of 304 stainless steel and nitinol. There is also an acrylic fiber with PVC jacket and an acetal connector. Both connectors plug into existing laser and light sources.
The device is designed to be an accessory for an Iridex medical laser (cleared under K071687) in the Vis-NIR transmission range of 532 nm to 810 nm with a maximum power output of 2.5 Watts and that is appropriate for photocoagulation. The device can be used with other lasers but they must be FDA approved and also meet the above specifications. The light portion of the device was designed for use with the Bausch & Lomb Stellaris PC light source which is a component of the Bausch & Lomb Stellaris PC Vision Enhancement System (cleared under K101325). The Stellaris PC uses a 75 Watt Xenon arc lamp that emits light with an output of 30 lumens within the wavelength range of 441nm to 665nm (photocoagulation is not applicable to the illumination aspect of the probe).
Here's an analysis of the provided text regarding the acceptance criteria and study for the 23ga Curved Illuminating Laser Probe (K122997).
It's important to note that this 510(k) summary is for a substantially equivalent device, meaning much of the performance evaluation relies on demonstrating equivalence to an already cleared predicate device (Peregrine's Illuminated Laser Probe, K031023) rather than proving de novo safety and effectiveness through extensive clinical trials. Therefore, the information provided isn't as detailed as what might be found for a novel device.
Acceptance Criteria and Reported Device Performance
Given the nature of a 510(k) for substantial equivalence, the "acceptance criteria" are primarily defined by the performance characteristics of the predicate device. The goal is to show that the new device either meets or performs similarly to the predicate in key areas, or that any differences do not raise new questions of safety or effectiveness.
Performance Characteristic | Acceptance Criteria (from Predicate) | Reported Device Performance (23ga Curved Illuminating Laser Probe) |
---|---|---|
Max Threshold of Laser Fiber | 3000 mW | 3000 mW |
Transmission Range of Laser Fiber | 180nm to 1,150nm | 180nm to 1,150nm |
Laser Power Efficiency | ≈ 95.5% | ≈ 95.0% |
Laser Spot Size | ≈ 2.0 inches | ≈ 1.90 inches |
Illumination Output | Not explicitly quantified, but assumed to be adequate for ophthalmic surgery. | Less than predicate device, considered acceptable by surgeons for smaller gauge instruments. |
Laser Field Clarity | Not explicitly quantified, but assumed to be adequate. | Nearly identical to predicate device. |
Biocompatibility | Compliant with medical use standards. | 100% biocompatibility; all materials are safe for intended use. |
Cannula Insertion | Ability to pass through cannula without resistance/damage. | Displayed no resistance when passing through cannula system. |
Bend Testing (Needle Set) | Safe and effective. | Proved to be safe and effective. |
Transmission Efficiency | Nearly identical to predicate device. | Nearly identical to predicate device (across 3 types of lasers). |
Sterility (SAL) | 10⁻⁶ | 10⁻⁶ |
Shelf Life | Not specified for predicate. | 4 years from sterilization. |
Study Details
-
Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- Test Set Sample Size: Not explicitly stated as a number of "samples" in a traditional clinical study sense. The testing involved comparing parameters of one new device (23ga Curved Illuminating Laser Probe) against one predicate device (PD600.10).
- Data Provenance: The testing was conducted by the manufacturer, Peregrine Surgical. No information on the country of origin or whether it was retrospective/prospective is provided, but it would have been prospective testing specifically for this 510(k) submission.
-
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 in the context of this device. This is a comparison of physical and functional characteristics of medical instruments, not an evaluation requiring expert consensus on images or diagnoses. The "ground truth" for performance is established by direct measurement and comparison to the predicate's known performance or accepted engineering standards.
- The document mentions that "Surgeons understand that light outputs are compromised due to the use of smaller needle/tube gauges," implying a general expert consensus or understanding within the ophthalmic surgical community, but no specific experts were involved in a formal ground truth establishment process for the test set.
-
Adjudication method (e.g. 2+1, 3+1, none) for the test set
- Not applicable. This is not a study requiring adjudication of findings. Performance measurements were objective.
-
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 a physical ophthalmic instrument, not an AI-powered diagnostic device, so no MRMC study was performed.
-
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Not applicable. This is a physical medical device, not an algorithm. Performance tests were done on the device itself.
-
The type of ground truth used (expert consensus, pathology, outcomes data, etc)
- The "ground truth" for demonstrating substantial equivalence was the measured performance of the legally marketed predicate device (PD600.10) and established engineering/biocompatibility standards. For biocompatibility, testing results demonstrating 100% biocompatibility according to recognized standards served as the ground truth. For sterility, the specified SAL and validation method (AAMI Overkill, ISO 11135-1) serve as the ground truth.
-
The sample size for the training set
- Not applicable. This is a physical device, not an AI-based system requiring a training set.
-
How the ground truth for the training set was established
- Not applicable given that no training set was used.

For the delivery of forced humidified air or fluid during ophthalmic surgery.
The Peregrine Wet Set is an 8' tubing set designed to deliver humidified air or fluid into the eye during ophthalmic surgery. It consists of the following: An 8' PVC tube running from an air supply unit to a three channel IV spike for insertion into a bottle of Balanced Salt Solution. The three way spike is designed to inject the air from the air supply unit through the solution, while at the same time deliver humidified air and saline through a dual PVC tube. The dual PVC tube is designed to transport the humidified air in one side and the saline in the other. The dual PVC tube attaches at the other end to a three way stopcock.
The provided text is a 510(k) Premarket Notification Summary for the Peregrine Wet Set, an air/fluid tubing set for ophthalmic surgery. This document primarily focuses on establishing substantial equivalence to predicate devices and does not contain information about specific acceptance criteria, performance studies, or clinical trial data as would typically be found for a device requiring such evidence for approval.
Therefore, many of the requested details about acceptance criteria, study design, ground truth, and reader performance cannot be extracted from this document.
However, based on the provided text, here is what can be inferred or stated:
-
A table of acceptance criteria and the reported device performance:
The document does not explicitly list acceptance criteria as quantitative thresholds for performance. Instead, it relies on a "Substantial Equivalence Comparison" table to show that the Peregrine Wet Set has similar features to two predicate devices (GRIESHABER GLOBAL CONTROL and ALCON VGFI TUBING SET). The "reported device performance" is implicitly that the device functions comparably to these predicate devices based on its design features.FEATURES GRIESHABER GLOBAL CONTROL (Predicate) ALCON VGFI TUBING SET (Predicate) PEREGRINE WET SET (Device) Number of channels in drip chamber spike 2 2 3 Pressurized air enters bottle /INTO FLUID /INTO AIR SPACE /INTO FLUID Pressurized air to stopcock delivered from AIR SYSTEM AIR SYSTEM BOTTLE Fluid Source BOTTLE BOTTLE BOTTLE Air system required YES YES YES Bottle hung at eye level YES YES YES Bottle pressurized by air system YES YES YES Delivery line for fluid to stopcock YES YES YES Delivery line for air to stopcock YES YES YES 3-way stopcock for air/fluid selection YES YES YES Filter at air line attachment to system YES YES YES Extension tube into bottle air space NO YES YES The key "acceptance criteria" here appear to be demonstrating that the Peregrine Wet Set possesses the functional characteristics necessary for its intended use, a fact supported by its design being largely analogous to legally marketed predicate devices, with some minor differences noted (e.g., 3 channels vs. 2, and the source of pressurized air to the stopcock). For sterility, the acceptance criterion is that it is ETO sterilized, with validation using the AAMI Overkill Method.
-
Sample size used for the test set and the data provenance (e.g., country of origin of the data, retrospective or prospective):
The document does not describe a clinical performance study with a test set. This device is a tubing set, and its approval appears to be based on substantial equivalence to existing devices and verification of sterility, rather than performance in a patient cohort. -
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, as no clinical performance test set or ground truth establishment by experts is described for this type of device submission. -
Adjudication method (e.g., 2+1, 3+1, none) for the test set:
Not applicable, as no clinical performance test set or adjudication process is described. -
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 device is a simple tubing set used for delivering air or fluid, not an AI-powered diagnostic or assistive tool. -
If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:
Not applicable. This device is a physical medical device, not an algorithm. -
The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
Not applicable, as no clinical performance study requiring ground truth is described. The relevant "truths" for this submission are the device's physical features, materials, and sterilization efficacy, which are evaluated against established standards and predicate devices. -
The sample size for the training set:
Not applicable. There is no training set mentioned for this device, as it is not an AI/machine learning device. -
How the ground truth for the training set was established:
Not applicable, as there is no training set.

For pneumatic infusion of silcone oil into the posterior segment.
The Peregrine V.F.I. Tubing Set is 8' in length and designed to infuse silicone oil into the posterior segment of the eye. It consists of the following: A connector at the proximal end to fit into a pneumatic injection system, 8' PVC tubing running from the connector and attaching to a Delrin Syringe Head which incorporates a .2um filter, and a syringe assembly (Terumo) which is attaches to the syringe head.
The provided document is a 510(k) Premarket Notification for a medical device called the "V.F.I. (Viscous Fluid Injection) Tubing Set." It seeks to establish substantial equivalence to a predicate device, rather than demonstrate performance against specific acceptance criteria through a study.
Therefore, many of the requested elements (acceptance criteria, device performance table, sample sizes, expert involvement, adjudication methods, MRMC studies, standalone performance, ground truth types and establishment for training sets) are not applicable to this type of regulatory submission.
The document primarily focuses on:
- Device Description: What the Peregrine V.F.I. Tubing Set is and what it's used for.
- Substantial Equivalence Comparison: Directly comparing its features to a legally marketed predicate device (Grieshaber & Co. V.I.S. Pack Tubing Set).
- Sterility: Mentioning that the device will be ETO sterilized and the validation method (AAMI Overkill Method).
- Intended Use: For pneumatic infusion of silicone oil into the posterior segment.
Key points from the document regarding the "study" for regulatory approval:
- Acceptance Criteria: The primary "acceptance criterion" for this 510(k) submission is that the device is substantially equivalent to a legally marketed predicate device. This is determined by comparing its design, materials, indications for use, and technological characteristics.
- Study Proving Equivalence: The "study" is a comparative textual analysis presented in Section {1} "Substantial Equivalence Comparison." It lists features of the Peregrine V.F.I. Tubing Set alongside the predicate Grieshaber & Co. V.I.S. Pack Tubing Set.
- Reported Device Performance: The document states: "The Peregrine V.F.I. Tubing Set, product #PD300.01, is identical to the Grieshaber V.I.S. Pack with the exception of the labeling specifications." This implies that its performance is expected to be identical to the predicate.
Here's a breakdown of the requested information based on the provided text:
1. A table of acceptance criteria and the reported device performance
Acceptance Criteria (for 510(k) Equivalence) | Reported Device Performance/Comparison |
---|---|
Substantial Equivalence to Predicate Device | Peregrine V.F.I. Tubing Set is "identical" to the Grieshaber V.I.S. Pack (predicate device) with the exception of labeling specifications. |
Intended Use | For pneumatic infusion of silicone oil into the posterior segment. (Matches predicate) |
Design/Materials | Nylon connectors, PVC Tubing 8', Delrin Syringe Head, Terumo Syringe 35cc, Gelman .2um filter. (Matches predicate) |
Sterility | ETO Sterilized, validated by AAMI Overkill Method. (Implied to be equivalent/acceptable for this type of device) |
Single Use | Single Use (Matches predicate) |
2. Sample size used for the test set and the data provenance
- Sample Size: Not applicable. This was a comparative analysis of device specifications, not a clinical trial or performance study requiring a "test set" of patient data or device units to be run.
- Data Provenance: Not applicable in the context of a clinical or performance study. The data provenance is the design specifications of the Peregrine device and the known specifications of the predicate device.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
- Not applicable. There was no "test set" requiring expert ground truth establishment in this type of submission. The "ground truth" for substantial equivalence is the set of specifications of the predicate device and the new device.
4. Adjudication method for the test set
- Not applicable. No "test set" or adjudication process for performance data was described.
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 device is a medical tubing set, not an AI-powered diagnostic or assistive technology.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done
- Not applicable. This device is a physical tubing set, not an algorithm.
7. The type of ground truth used
- The "ground truth" for this 510(k) submission is the documented specifications and indications for use of the predicate device (Grieshaber V.I.S. Pack Tubing Set). The new device is then compared against this "truth" to establish equivalence.
8. The sample size for the training set
- Not applicable. There is no "training set" for this type of device submission.
9. How the ground truth for the training set was established
- Not applicable. There is no "training set" for this type of device submission.
