2. Sample size used for the test set and the data provenance
The document details testing conducted on the device itself and does not refer to a "test set" in the context of diagnostic data. The tests performed are for physical and functional properties of the biopsy needle.
- Sample size: Not explicitly stated for each test, but standard testing practices involve a sufficient number of samples to ensure representativeness and statistical validity.
- Data provenance: Not applicable in the context of patient data; the data is generated directly from testing manufactured devices.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
Not applicable. This is a physical device. Ground truth refers to diagnostic accuracy in AI/imaging studies.
4. Adjudication method for the test set
Not applicable. Adjudication methods are used to establish ground truth in diagnostic studies, typically involving disagreements between expert readers.
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 a physical device, not an AI-assisted diagnostic tool.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This is a physical device.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
For the "Comparative study" mentioned in section 4 (Non-Clinical Tests), the ground truth for evaluating sampling performance would inherently be pathology-based assessment of the collected tissue samples (e.g., measuring sampling weight and assessing cell integrity). While not explicitly stated as "ground truth," this is the objective measure used to compare the device's performance against predicates.
8. The sample size for the training set
Not applicable. This is a physical device, not an AI model requiring a training set.
9. How the ground truth for the training set was established
Not applicable. This is a physical device, not an AI model.

Difference 1: Visualization technique
The difference between the Subject device and the predicate device is the subject device not imaging under the CT. The usability of the subject device under CT has been verified.
Difference 2: Materials
The difference between the Subject device and the predicate device is the PC material. PC do not come into contact with patients, so it will not bring safety risks
Difference 3: Needle Gauge
Subject device has two gauge sizes (17G, 24G) more than predicate devices. The 17G OD and 24G OD of Cutting cannula of subject device are within the predicate devices'. It will not cause new risks to device safety and effectiveness.
Difference 4: Needle Length
It can be seen from the table above that subject device provides more selections on the Length of Cutting Cannula, namely 40mm, 60mm, 70mm,
Page 11
110mm, 120mm, 130mm, 140mm, 160mm, 170mm, 180mm, 190mm, 210mm, 220mm, 230mm, 240mm, 250 mm. The 60mm, 70mm, 110mm, 120mm, 130mm, 140mm, 160mm, 170mm, 180mm, 190mm are within the length range (50mm to 200mm) of predicate devices. Besides, considering the different shape of patients and the distance between needle insertion point and lesion, 40mm, 210mm, 220mm, 230mm, 240mm and 250mm are provided by subject device. The puncture length is judged by the clinician, and we offer a wider selection of puncture lengths that do not raise new issues affecting the safety and effectiveness of the devices. The additional puncture lengths are similar to other marketed products with the same intended use.
Difference 5: Cutting Cannula tip type
The puncture process: The Chiba type has a blade on the tip of Cutting cannula for puncture, while the Greene type has a blade on the tip of Inner stylet, but both use a combination of the Cutting cannula and Inner stylet to achieve puncture, and the process is the same.
The sampling process: When sampling with the Chiba type, the Inner stylet is withdrawn, and only the Cutting cannula is operated to take a sample at the lesion site. The tip of Cutting cannula can move back and forth with the operator's technique, but high demands are placed on the operator's technique to avoid damaging the tissue around the needle. When sampling with the Greene type, the Inner stylet is withdrawn, and only the Cutting cannula is operated to take a sample at the lesion site. The tip of Cutting cannula is flat and dull, and it is not easy to move back and forth with the operator's technique. Despite this difference in design, performance testing in the indicated tissue types demonstrated substantially equivalent safety and effectiveness.
Difference 6: Anatomical sites
Though the indications for use descriptions are not identical, the specific indications designating anatomical sites are within the same intended use as the predicate and do not raise different questions of safety and effectiveness.
Based on the risk analysis of the above differences, the differences do not affect the safety and effectiveness of the equipment.

- A comparative study was conducted between CuraWay's Disposable Biopsy Needle and the predicate devices across various tissues including liver, kidney, breast, thyroid, prostate, spleen, pancreas, lymph nodes, and lungs. The results showed no significant difference in sampling weight or cell integrity between the subject and predicate devices.
5. Clinical data
No clinical data was provided.
