Mechanism Performance
Depth Projection (Cannula Advancement > 20 mm)Subject devices (Model 111, Model 121) were comparable to predicate devices over 50 shots per use and met criteria (Needle Advancement > 20 mm). N/A for Model 112 as design is different.
Mechanical Durability (Breakage Force (SHENGWEI) > FPredicate; Detachment of Components Does Not Occur)Subject devices were comparable to predicate devices and met criteria (Breakage Force (SHENGWEI) > FPredicate and Detachment of Components: Does Not Occur).
Penetration Force (Penetration Force (SHENGWEI) < FPredicate)Subject devices (Model 112, Model 121; Model 111 uses same needle as Model 121) required less force compared to predicate devices and met criteria (Penetration Force (SHENGWEI) < FPredicate).
Activation Force (Spring) (Activation Force (Shengwei) < FPredicate)Subject devices were comparable to predicate devices over 50 shots per use and met criteria (Spring Force (Shengwei) > F Predicate). (Note: There is a discrepancy in the table criteria vs. text description for Activation Force).
Extraction (Shengwei Non-statistically Significant Different to Predicate)Subject devices (Model 111/112/121) were comparable over 50 shots per use and produced slightly larger samples by weight compared to predicate devices. This is described as "Statistically Sig. Diff. (Shengwei Sample Wt. > Predicate Sample Wt.)" in the summary table.

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

  • Sample Size: For performance testing (Depth Projection, Penetration Force, Activation Force, Mechanical Durability, Extraction), "Samples of each device product family (subject device) were selected at the extremes of device design for needle length and gauge sizes." For Depth Projection, Activation Force, and Extraction, testing was performed "over 50 shots per use." For Penetration Force, "Each tested subject and predicate device was activated 50 times." For Shelf-life, "Three lots of aged and non-aged subject devices were tested in triplicate."
  • Data Provenance: The document does not explicitly state the country of origin of the data for these performance tests. It also does not explicitly state whether the tests were retrospective or prospective, but given they are laboratory performance tests, they are inherently prospective for the purpose of this submission.
  • Clinical Data: No clinical data was included in this submission.

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 information is not applicable as the studies described are laboratory performance tests focusing on mechanical and biological properties of the device, not clinical performance requiring expert interpretation or ground truth establishment in a medical context.

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

  • This information is not applicable as the studies described are laboratory performance tests measuring quantifiable physical properties of the device, not clinical studies involving interpretation or adjudication.

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

  • No MRMC study was done. This document is for a medical device (biopsy needle), not an AI-assisted diagnostic tool for human readers.

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

  • No standalone (algorithm only) performance study was done. This document is for a physical medical device (biopsy needle), not a diagnostic algorithm.

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

  • For biocompatibility, the ground truth is established by recognized international standards (ISO 10993 series and USP tests) which define acceptable biological responses.
  • For performance testing, the ground truth is established by specific criteria outlined in the testing protocols (e.g., "Needle Advancement > 20 mm," "Breakage Force (SHENGWEI) > FPredicate") and comparison to legally marketed predicate devices. Quantitative measurements are taken against these predefined standards or predicates.

8. The sample size for the training set

  • This information is not applicable as the document describes laboratory performance and biocompatibility testing for a physical medical device, not a machine learning model that would require a training set.

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

  • This information is not applicable for the same reason as point 8.

  • Acute Systemic Toxicity-(ISO 10993-11:2017)
  • Hemolysis-(ISO 10993-4:2017).

The devices met the requirements for non-pyrogenicity per Pyrogen Test USP<151>, Bacterial Endotoxins Test USP<85>. Sterilization was validated per ISO11135, and residuals for ETO, EG and ECH met ISO10993-7.

Device Shelf-life

The subject devices in their packaging were subjected to accelerated aging to simulate a 5 year shelf life (Treatment: 60°C, 28 days, <50% RH). Three lots of aged and non-aged subject devices were tested in triplicate for Mechanical Durability, Depth Projection, Device Needle Penetration, Activation Force (Spring Force) and Extraction to assess the impact of simulated aging on the device performance. Visual Appearance inspection for Metal Oxidation, Plastic Coloration, Plastic Integrity (cracks, damage) indicated that there no aesthetic, or design changes for the aged devices. Performance testing results of the aged devices was unchanged compared to untreated (non-aged) device.

Performance testing

Samples of each device product family (subject device) were selected at the extremes of device design for needle length and gauge sizes for comparative testing to predicate devices for device performance.

Depth Projection: Subject devices vs. predicate devices testing for Depth Projection measured the needle advancement during activation. Cannula needle advancement must meet a distance of ≥ 20mm compared to the notch. The results showed that subject devices tested side-by-side with predicate devices were comparable over 50 shots per use and met criteria: Needle Advancement > 20 mm.

Penetration Force: Subject devices vs. predicate devices for Penetration Force was assessed using ASTM F3014 guidance. Simulation of biological tissues using a certified testing foil was used in the Dynamometer setup. Each tested subject and predicate device was activated 50 times to replicate the maximum number of biopsy shots performed during a medical procedure. The results showed that the subject devices required less force compared to the predicate devices and met the criteria: Penetration Force (Shengwei) < F (Predicate).

Activation Force: Subject and predicate device testing for Spring Force was measured during device activation. The results showed the subject devices tested side-by-side with predicate devices were comparable over 50 shots per use and met criteria: Spring Force (Shengwei) > F Predicate.

Mechanical Durability: Subject and predicate device testing for Mechanical Durability was performed in two parts: breaking force and detachment force. Device cannulas subjected to progressive force determined the breaking force. The detachment force test determined the point at which the plastic components sever from the device point of attachment. Results showed that subject devices in comparison to the predicate device met the criteria, Breakage Force (Shengwei) > F (Predicate), and Detachment of Components: Does Not Occur.

Extraction Testing: Subject and predicate devices testing for Sample Extraction quantitatively evaluated extraction capacity of subject devices compared with predicate devices. The results showed that the subject devices tested side-by-side with predicate devices were comparable over 50 shots per use compared to the predicate device. Model 111/112/121 devices produced slightly larger samples by weight compared to predicate device at 50 shots per use.

8. CLINICAL DATA

No clinical data was included in this submission.

9. CONCLUSION

The indications for use statement for the subject device is similar to that of the predicate. The differences between the biopsy needle and its predicate device do not raise new issues of safety and effectiveness. The non-clinical data support the safety of the device and the performance testing report demonstrate that the medical face mask should perform as intended in the specified use conditions.

From the results of non-clinical data including the performance testing described, Guangzhou Shengwei Medical Devices Co., Ltd concludes that the biopsy needle is as safe, as effective, and performs as well as or better than the legally marketed as the predicate devices (K853312, K133948, K160316).
