B. Study Details (as inferable from the document for a physical device)
-
Sample sizes used for the test set and the data provenance:
- Sample Size: Not explicitly stated for specific tests (e.g., how many instruments were tested for tensile strength or how many biopsies were taken in ex-vivo tests). The document states "ex-vivo testing was conducted on porcine tissue" using 12G, 14G, and 20G models.
- Data Provenance: The biocompatibility testing followed ISO 10993-1:2018. The ex-vivo testing was done on "porcine tissue." The context suggests these are laboratory-controlled, prospective tests conducted by the manufacturer, Bard Peripheral Vascular, Inc. No country of origin for the data is specified, but typically, these studies are conducted in the country of the manufacturer or approved testing facilities.
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- Not Applicable / Not Provided for this device. For physical devices like biopsy instruments, the "ground truth" is measured against engineering specifications and material properties (e.g., tensile strength, successful sterile barrier). Expert consensus (like in image interpretation) is not directly relevant to these types of performance tests. The ex-vivo tissue quality assessment would likely involve pathologists or relevant subject matter experts, but their number and qualifications are not specified.
-
Adjudication method (e.g., 2+1, 3+1, none) for the test set:
- Not Applicable / Not Provided for this device. Adjudication methods like 2+1 are typically used in clinical studies or studies involving subjective human interpretation (e.g., reading medical images). For the mechanical and material tests described, results are objective measurements against predefined specifications.
-
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. This is not an AI/ML device. An MRMC study is completely irrelevant to this type of medical device (physical biopsy instrument).
-
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- No. This is not an AI/ML device. Standalone performance testing refers to the performance of an algorithm without human intervention, which does not apply here.
-
The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- For Biocompatibility: Compliance with ISO 10993-1:2018 standards and specific test results (cytotoxicity, sensitization, etc.).
- For In Vitro Physical Performance: Engineering specifications, design tolerances, and established industry standards for mechanical properties.
- For Ex-vivo Testing: The "sample quality" on porcine tissue would likely be assessed against histological standards (e.g., tissue integrity, architecture, presence of target cells). Whether this involved expert pathology consensus or objective criteria is not specified, but it would fall under a form of "pathology" ground truth for the sample quality.
-
The sample size for the training set:
- Not applicable. This device is a physical instrument, not an AI/ML model that requires a training set.
-
How the ground truth for the training set was established:
- Not applicable. This device is a physical instrument, not an AI/ML model that requires a training set.

The ALARA BMA Neuro Access Kit (ALARA BMAN and ALARA BMAC Kit) is indicated for aspiration of bone marrow or autologous blood.
The ALARA BMA Neuro Access Kit is indicated for pedicle pilot hole preparation, locating, and identifying spinal roots / nerves by providing proximity feedback.
The ALARA BMAC Needle is intended for use in harvesting core biopsy samples of cancellous bone and/or bone marrow.
The ALARA BMA Neuro Access Kit utilizes a neuromonitoring platform in providing the surgeon with nerve / root location feedback during the approach to a pedicle to support a guidewire placement.
The ALARA BMAN and ALARA BMAC Kit includes various single-use needles designed for bone marrow aspiration and aspiration of autologous blood.
This document is an FDA 510(k) clearance letter for a medical device called the "ALARA BMA Neuro Access Kit." This type of document primarily focuses on establishing "substantial equivalence" to predicate devices, rather than presenting detailed study results for a new AI/ML-driven diagnostic device.
Therefore, the provided text does not contain the information requested regarding acceptance criteria and a study proving a device meets these criteria in the context of an AI/ML diagnostic. The "Performance Testing" section lists various engineering and material tests (e.g., torque, pull, strength, sterilization, biocompatibility) relevant to the physical components of the device, not performance metrics for an AI algorithm.
Here's why the requested information cannot be extracted from this document:
- No AI/ML Component: The device description and performance testing sections indicate a physical medical instrument (needles for biopsy, aspiration, and a neuromonitoring platform for "proximity feedback" during pedicle preparation). There is no mention of an AI or machine learning algorithm. The "proximity feedback" is likely an electrical or mechanical system, not an AI interpreting images or data.
- Focus on Substantial Equivalence: A 510(k) clearance is primarily about demonstrating that a new device is "substantially equivalent" to a legally marketed predicate device. This often relies on comparing design, materials, intended use, and non-clinical performance (like the engineering tests listed). It does not typically involve the rigorous clinical efficacy studies or AI performance validation described in your prompt.
- Lack of Diagnostic Claims: The device is for "aspiration of bone marrow or autologous blood," "pedicle pilot hole preparation, locating, and identifying spinal roots / nerves by providing proximity feedback," and "harvesting core biopsy samples." These are procedural/interventional uses, not diagnostic uses that would involve interpreting data (image, signal, etc.) with an AI.
In summary, as the provided document pertains to a physical medical device and not an AI/ML-driven diagnostic, the questions about acceptance criteria for AI performance, sample sizes for test/training sets, expert adjudication, MRMC studies, standalone performance, and ground truth establishment for AI are not applicable to the content provided.

The Forsvall biopsy needle is intended to collect histological biopsy samples from soft tissue intended for clinical examination. The Forsvall biopsy needle is part of the Forsvall biopsy needle system for prostate biopsy and shall be used together with the Forsvall biopsy gun.
The Forsvall biopsy gun is intended to be used by medical professionals, together with the Forsvall biopsy needle, on male patients to obtain soft tissue samples. The Forsvall biopsy gun is part of the Forsvall biopsy needle system for prostate biopsy.
The Forsvall biopsy needle system for prostate biopsy is indicated whenever there is a need to obtain prostate biopsy samples.
The Forsvall biopsy needle system for prostate biopsy consists of two items: the Forsvall biopsy needle and the Forsvall biopsy gun. The Forsvall biopsy needle is intended for use with the Forsvall biopsy gun. The Forsvall biopsy gun is reusable and the biopsy needle is single use. The Forsvall biopsy system uses a spring loaded gun that mediates a biopsy needle with a side notch used to obtain tissue samples. The biopsy gun is made of metal and hard plastic and the 16/18 gauge 10/15/20/25 cm biopsy needle is made of stainless medical grade steel.
By pulling a handle on the Forsvall biopsy gun, the front wagon therein is tensioned and connected to the Forsvall biopsy needle. When tensioning the load pin also moves along a guide curve. When the front wagon is in its loaded position, the load pin has moved the front needle bracket a small distance backwards in the Forsvall biopsy gun.
The handle is pulled a second time to tension the rear wagon that is connected to the needle in the Forsvall biopsy needle. A tension is created between the outer tube and the needle in order to force closing of the Forsvall biopsy needle. The purpose is to prevent an interstice from arising in order to prevent accumulation of bacteria.
The Forsvall biopsy gun is fired by pushing the trigger, which causes the rear wagon to move forward of the front wagon. This results in the inner part of the needle being forced forward, followed by forward movement of the outer tube. When the Forsvall biopsy gun is fired, the load pin moves the outer tube the final millimeter in order to achieve a soft closing mechanism. On the Forsvall biopsy needle, the outer tube thus stops against the needle head and it is forced closed.
The Forsvall biopsy operates by the outer tube stopping against the needle head in the closing motion. Additionally, the final millimeter in the closing motion is a soft close action in order to protect the needle head from too strong forces. To enable the soft closing action, the Forsvall biopsy gun has a design similar to the predicate device.
This looks like a 510(k) summary for a medical device called the "Forsvall biopsy needle system for prostate biopsy." Unfortunately, the provided text does not contain the information necessary to answer your questions about acceptance criteria and the study proving the device meets them.
The document focuses on demonstrating substantial equivalence to a predicate device (Möller Medical Biopsy Needles and Systems) based on similar indications for use, technological characteristics, and general safety and performance.
Here's why I cannot provide the requested information from the given text:
- Acceptance Criteria and Device Performance Table: The document lists "Non-Clinical and/or Clinical Tests Summary & Conclusions," but it does not provide specific acceptance criteria (e.g., minimum sample length, specific force measurements) or a table comparing these criteria to the device's reported performance. It only states that "All non-clinical tests related to performance as described above passed."
- Study Details (Sample Size, Data Provenance, Experts, Adjudication, MRMC, Standalone, Ground Truth, Training Set): The document briefly mentions "User Testing" in a "simulated clinical setting" but provides no details about:
- The sample size of this user testing.
- The provenance of any data (e.g., country, retrospective/prospective).
- The number or qualifications of experts.
- Adjudication methods.
- Whether it was an MRMC comparative effectiveness study or a standalone study.
- The type of ground truth used.
- Any training set information.
In summary, the provided FDA 510(k) summary (K242128) does not contain the detailed study information you are asking for regarding acceptance criteria and performance data. It's a regulatory document focused on establishing substantial equivalence, not a detailed scientific study report. Such detailed study information would typically be found in the full 510(k) submission, which is not publicly available in its entirety.

The Triopsy Biopsy System (instrument and needles) is intended for use in obtaining biopsies from the prostate.
The Triopsy Medical Actuator and Biopsy Needle is comprehensive system that aids in the diagnosis and treatment planning of prostate cancer. The system utilizes an actuator instrument and biopsy needle (disposable) with the intention of gathering prostate tissue and properly identifying its pathology. The needle collects full-length, unbroken apex-to-base core samples with patented ridges that hold and protect the sample's integrity. The actuator allows for variable sample lengths for each area of the prostate to be biopsied increasing accuracy and patient safety by avoiding under or overshooting.
This FDA 510(k) summary describes the Triopsy Biopsy System, consisting of the Triopsy Actuator and Triopsy Biopsy Needles, intended for obtaining prostate biopsies. The submission leverages a comparison to a predicate device, the Bard Magnum Reusable Core Biopsy Instrument & Bard Magnum Disposable Biopsy Core Needle (K934370 & K934371), to demonstrate substantial equivalence.
Here's an analysis of the acceptance criteria and study information provided:
1. Table of Acceptance Criteria and Reported Device Performance
The document doesn't explicitly present a table of acceptance criteria with corresponding performance metrics in a clear, quantitative manner. Instead, it lists performance requirements that were verified and states that the device "successfully passed all of the results."
Inferred Acceptance Criteria based on the provided text:
Acceptance Criterion (Inferred from "performance requirements") | Reported Device Performance |
---|---|
Depth Projection | Verified |
Mechanical Durability | Verified |
Penetration | Verified |
Activation Force (Spring) | Verified |
Sample Extraction | Verified |
Human Factors/Usability (under clinical conditions) | Validated intended use |
The document concludes that the device is "safe, effective, and performs as well or better than the predicate device," and that "technological differences do not introduce or raise new or different questions of safety and effectiveness."
2. Sample Size Used for the Test Set and Data Provenance
The document does not specify the sample size used for the verification and validation (V&V) testing (e.g., how many biopsy procedures were simulated, how many actuations were performed for mechanical durability, or how many users participated in human factors studies).
The data provenance is also not explicitly stated in terms of country of origin or whether studies were retrospective or prospective. Given the nature of performance testing (mechanical, human factors), these are typically prospective studies performed in a controlled environment (e.g., a lab or simulated clinical setting).
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications
The document does not mention the use of experts to establish a ground truth for the non-clinical and human factors studies described. These types of tests typically rely on objective measurements and established standards rather than expert consensus on diagnostic outcomes. For pathological evaluation of biopsy samples, there is no mention of experts, suggesting the focus was on the physical characteristics of the sample (e.g., full-length, unbroken) rather than the diagnostic accuracy of the device in a clinical context.
4. Adjudication Method for the Test Set
The document does not describe an adjudication method as it pertains to expert reviews of images or data to establish ground truth. The testing mentioned (depth projection, mechanical durability, etc.) would be assessed against predefined engineering specifications and performance targets, not requiring an adjudication process.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
An MRMC comparative effectiveness study was not conducted, or at least not described in this 510(k) summary. These studies typically assess human reader performance with and without AI assistance, which is not relevant to the mechanical and usability testing described for this biopsy system.
6. Standalone Performance Study
A standalone performance study was not conducted in the sense of an algorithm-only performance to derive diagnostic metrics like sensitivity or specificity. The device is a mechanical biopsy system, not an AI or imaging-based diagnostic algorithm. The "standalone" performance here refers to the device's ability to consistently perform its intended mechanical functions (e.g., penetration, sample extraction) and meet safety requirements. The document indicates that the device's performance requirements were verified through performance testing.
7. Type of Ground Truth Used
For the non-clinical tests:
- Engineering specifications and objective measurements were used as the "ground truth" to verify performance criteria such as depth projection, mechanical durability, penetration, activation force, and sample extraction.
- For human factors studies, the "ground truth" was likely the successful and safe completion of tasks by intended users in simulated clinical scenarios, as evaluated against predefined usability criteria.
There is no mention of pathology, outcomes data, or expert consensus serving as a ground truth for diagnostic accuracy, as this submission focuses on the safety and performance of the biopsy instrument itself, not its diagnostic outcome directly.
8. Sample Size for the Training Set
The concept of a "training set" is not applicable to this submission, as the Triopsy Biopsy System is a mechanical device, not a machine learning or AI-driven system that requires training data.
9. How the Ground Truth for the Training Set Was Established
As noted above, a training set is not applicable, so the establishment of ground truth for a training set is not relevant to this submission.

The Mammotome AutoCore™ Single Insertion Core Biopsy System is indicated to obtain tissue samples from the breast or lymph nodes for diagnostic analysis of breast abnormalities. This instrument is for diagnostic use only and is not indicated for therapeutic use.
The extent of a histologic abnormality cannot always be reliably determined from the palpation or imaged appearance. Therefore, the extent of removal of the palpated or imaged evidence of an abnormality does not predict the extent of removal of a histologic abnormality, e.g., malignancy. When the sampled abnormality is not histologically benian, it is essential that the tissue marqins be examined for completeness of removal using standard surgical procedures.
The Mammotome AutoCore™ Single Insertion Core Biopsy System is an automated core needle biopsy system. It is a single insertion, multiple sample device that includes automated arming and automated sample collection. It is available in two gauge sizes (12G and 14G) and acquires soft tissue samples using a spring-loaded inner piercing stylet and outer cutting cannula in the probe needle.
The provided text does not contain detailed acceptance criteria or extensive study results that prove the device meets specific performance metrics. It primarily discusses the regulatory submission for the Mammotome AutoCore™ Single Insertion Core Biopsy System.
However, based on the limited information regarding performance testing, here's what can be extracted and inferred:
1. A table of acceptance criteria and the reported device performance:
The document mentions several performance tests were conducted. While specific acceptance criteria values are not provided, the table below lists the characteristics tested, which implies that the device met the internal acceptance criteria for each test to achieve substantial equivalence.
Characteristic | Acceptance Criteria (Not Explicitly Stated, but implied to be met for SE) | Reported Device Performance (Implied to meet criteria) |
---|---|---|
Static force to penetrate | Not provided | Comparison performed, substantial equivalence confirmed |
Lesion displacement | Not provided | Comparison performed, substantial equivalence confirmed |
Overmold bond strength | Not provided | Comparison performed, substantial equivalence confirmed |
Bend load | Not provided | Comparison performed, substantial equivalence confirmed |
Sample weight | Not provided | Appropriate sample weight achieved |
Sample acquisition | Not provided | Appropriate sample acquisition achieved |
Sample quality | Not provided | Appropriate sample quality achieved |
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):
- Bench Testing: The document does not specify sample sizes for the bench tests (static force, lesion displacement, overmold bond strength, bend load). It also does not specify data provenance or if it was retrospective or prospective.
- Animal Testing: The document does not specify sample sizes for the animal testing. It also does not specify data provenance or if it was retrospective or prospective.
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):
The document does not describe any human expert involvement in establishing ground truth for the performance tests mentioned. The tests appear to be primarily engineering and animal model assessments.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:
No information is provided about adjudication methods for the test sets, as the studies described are not clinical or interpretative in nature where adjudication would typically be relevant.
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. The Mammotome AutoCore™ is a physical biopsy system, not an AI-powered diagnostic tool. Therefore, an MRMC study related to human reader performance with or without AI assistance would not be conducted for this device.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done:
Not applicable, as this is a physical medical device and not an algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc):
- Bench Performance: For bench tests, the ground truth would be based on engineering specifications and physical measurements, rather than clinical or pathological ground truth as defined in diagnostic studies.
- Animal Performance: For animal testing, the ground truth for "appropriate sample weight, acquisition, and quality" would likely be determined by veterinary pathologists or other trained personnel assessing the biopsy samples obtained from the animal models, comparing them against established criteria for diagnostic-quality tissue samples.
8. The sample size for the training set:
Not applicable. This document describes the regulatory submission for a physical medical device, not an AI or machine learning algorithm that requires a training set.
9. How the ground truth for the training set was established:
Not applicable, as there is no training set for this device.
