More-Cell-System is intended for use as a tissue containment system during minimally invasive gynecologic laparoscopic surgery to enable the isolation and containment of tissue considered benign, resected during multi-site laparoscopic surgery for power morcellation and removal.
When used in women with fibroids, the More-Cell System is for women who are pre-menopausal and under age 50. More-Cell-System is compatible with electromechanical laparoscopic power morcellators that are between 12 mm and 20 mm in shaft outer diameter and between 95 mm and 170 mm in shaft working length.
The More-Cell-System device is used as a receptacle for collection and extraction of tissue during laparoscopic surgical procedures (e.g., hysterectomy and myomectomy). The key components of the device include the following:
-
A. More-Cell Bag: A single use, insufflatable, transparent, EO sterilized bag made of 50 µm thick polyurethane film that is biocompatible and cell-tight. The bag includes printed lines to aid in visualization during surgery. There are two openings to the bag: one opening that is 16 cm in diameter where a morcellator can be inserted (and where tissue can be removed), and a second opening that is 16 mm in diameter x 190 mm in length where a laparoscope can be inserted to visualize the surgical procedure. The bag capacity is 2.5 L (340 x 250 mm).
-
B. Visi-Shield: A metal sleeve with a polycarbonate window for lens protection (comes in 0° or 30° angle) that is cell-tight to protect the laparoscopic camera during a surgical procedure. Using the Visi-Shield the surgical procedure can be visualized without compromising the integrity of the bag, laparoscopic view, or safety of the laparoscopic camera.
Here's a breakdown of the acceptance criteria and the studies that prove the device meets them, based on the provided text:
1. Table of Acceptance Criteria and Reported Device Performance

| Proper Deployment, Morcellation, and Removal | Intended users can adequately deploy the device, morcellate a specimen without compromising device integrity, and remove the device without spillage of contents. | Demonstrated in usability studies: 26 clinical cases (outside US) showed pass-criteria satisfied, no leaks, and no failures. 11 US surgeons in a simulated use study showed no use errors and adequate comprehension of procedural tasks. No spillage observed in clinical cases. |
| Training & Instructions for Use | Training developed and validated to ensure users can follow instructions for use. | Usability studies (26 clinical cases, 11 US surgeons simulated use) demonstrated that no additional training beyond review of labeling and videos is necessary. |
2. Sample Sizes Used for the Test Set and Data Provenance
- Impermeability Testing: 36 More-Cell bags (retrospective, samples exposed to 2-years aging and simulated use).
- Mechanical Performance (various tests): 30 samples each (retrospective, samples exposed to 2-years simulated aging, with the exception of rivet testing).
- Animal Performance Testing: 16 animals (8 in test group with More-Cell-System, 8 in control group without). Type of data (retrospective/prospective) is not explicitly stated, but implies prospective due to it being an "in vivo porcine model" with randomized distribution. Country of origin not specified, but usually animal studies are controlled within a specific research facility.
- Clinical Usability Study (outside US): 26 clinical cases involving 26 surgeons. Data provenance: Austria (n=6), Germany (n=19), Switzerland (n=1). This is a prospective observational study.
- Simulated Use Study (US): 11 U.S. surgeons. Data provenance: US. This is a prospective simulated use study.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications
- Impermeability Testing: Not applicable. Ground truth was established by laboratory methods (immersion test with E. coli, positive and negative controls).
- Mechanical Performance: Not applicable. Ground truth was established by engineering specifications and objective measurements (e.g., force, pressure).
- Animal Performance Testing: "Two surgeons" performed the laparoscopic supracervical hysterectomy. Their qualifications are not specified beyond being "surgeons." Ground truth for the presence of disseminated myometrial cells was established by "positive cytology."
- Clinical Usability Study (outside US): 26 surgeons, with "various levels of experience." The "ground truth" here was subjective evaluation by the surgeons themselves (ease of insertion, visualization, etc.), and objective observation by study personnel for leaks and successful completion of procedures.
- Simulated Use Study (US): 11 U.S. surgeons "with a range of laparoscopic surgery experience (2.5 years to 30 years)." Similar to the other usability study, "ground truth" was adherence to critical tasks observed by study personnel, and subjective feedback from participants.
4. Adjudication Method for the Test Set
- Impermeability/Mechanical Testing: No specific human adjudication method mentioned, as these were objective lab tests comparing results against pre-defined acceptance criteria.
- Animal Performance Testing: "Positive cytology" determined disseminated cells. It's not specified if multiple pathologists or a single expert adjudicated the cytology results.
- Clinical Usability Study (outside US) & Simulated Use Study (US): The text mentions that surgeons were "asked to evaluate and record" and participants were "observed to assess adherence to critical tasks." This implies observation by study personnel. There is no explicit mention of an adjudication panel (e.g., 2+1 or 3+1) for discordant observations or evaluations; it appears to be direct observation and feedback.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
- No, a multi-reader multi-case (MRMC) comparative effectiveness study focusing on human readers improving with AI vs. without AI assistance was not performed. This device is a physical medical device (containment system), not an AI/software product, so this type of study would not be relevant.
6. Standalone (Algorithm Only) Performance Study
- No, a standalone (algorithm only) performance study was not done. As mentioned, this is a physical medical device, not an algorithm.
7. Type of Ground Truth Used
- Sterilization: Laboratory testing results (sterility assurance level).
- Shelf Life: Laboratory testing results (visual inspection, dye penetration, peel strength, microbiological stability) and functional testing.
- Biocompatibility: Laboratory testing results (cytotoxicity, sensitization, irritation, acute systemic toxicity).
- Impermeability: Laboratory testing results (E. coli immersion test) and cytology in animal model.
- Mechanical Testing: Engineering specifications and objective measurements (e.g., force, pressure via bench testing).
- Animal Performance: Pathological analysis ("positive cytology") for disseminated cells, and visual examination for bag breach.
- Usability Studies: Observational data on task completion, user feedback, and objective checks for leaks/damage.
8. Sample Size for the Training Set
No "training set" in the context of an AI/ML algorithm is mentioned or applicable here. The device is hardware. The studies described are for validation of the final device.

The Easylnstruments are indicated for cutting, grasping, dissecting and coagulation of tissue in laparoscopic surgical procedures.
The A.M.I. EasyInstruments device is a modular instrument system for use in laparoscopic highfrequency (HF) surgery and is designed for monopolar application. The Easylnstruments system comprises three-part detachable instruments, which include 1) different functional handles (EasyHandle), 2) instrument shafts of various diameters and lengths (EasyShaft), and 3) a wide range of different, application-specific attachments (EasyTips). It is intended during laparoscopic procedures to mobilize, manipulate, grasp, hold, fix, retract, dissect, cut, and coagulate tissue.
This FDA 510(k) summary describes a medical device, the EasyInstruments, which are electrosurgical cutting and coagulation devices and accessories. The document focuses on demonstrating substantial equivalence to predicate devices, rather than establishing acceptance criteria and performance against those criteria in a clinical study for a new AI/software component. Therefore, much of the requested information (like number of experts, adjudication methods, MRMC studies, ground truth for test/training sets, effect size of AI improvement) is not applicable or cannot be extracted from this document because it pertains to the evaluation of AI/software in a clinical context, which is not the subject of this 510(k) for electrosurgical instruments.
However, I can extract information related to the performance testing that was conducted to demonstrate safety and efficacy compared to predicate devices for these hardware instruments.
Here's an attempt to answer the questions based on the provided text, noting where the requested information is not present or applicable:
1. A table of acceptance criteria and the reported device performance
The document does not explicitly state acceptance criteria in precise numerical terms or detailed performance metrics in a table. It lists numerous tests performed to demonstrate safety and performance relative to predicate devices. The "reported device performance" is summarized as "The results of these tests indicate that the EasyInstruments are substantially equivalent to the predicate devices" and "it can be concluded that the subject device does not raise new issues of safety or efficacy compared to the predicate devices."
Below is a summary of the types of tests performed and the general outcome:
| Category | Test Performed | Reported Performance (General) |
|---|---|---|
| Cleaning & Sterilization | Cleaning validation per AAMI TIR12 and AAMI TIR30. Sterilization validation per ISO 17665-1, ISO 11135, and ISO 11137. | Demonstrated effective cleaning and sterilization. |
| Longevity & Integrity | Shelf life and packaging validation per ISO 11607. | Device maintains integrity and sterility over its shelf life. |
| Biocompatibility | Biocompatibility Risk Assessment per ISO 10993-1. Cytotoxicity testing per ISO 10993-5. Irritation and sensitization testing per ISO 10993-10. | Biocompatible; no undue patient risk from materials. |
| Electrical Safety | Electrical safety per IEC 60601-1 and IEC 60601-2-2. EMC per IEC 60601-1-2. | Meets electrical safety and electromagnetic compatibility standards. |
| Bench Performance | Performance of disposable tips, reusable tips after reprocessing, EasyHandle reprocessing, and EasyShaft after reprocessing. Performance tests for tips included visual inspection for damage, opening angle, ease of movement in opening/closing, cutting, dissecting, grasping strength, continuity check. Performance tests for EasyShaft and EasyHandle included visual inspection (e.g., cracks, damage, warpage), continuity check, dielectric strength, and compatibility check. | Maintains mechanical and electrical integrity and function. |
| Thermal Effects | Side-by-side testing on ex vivo animal tissues (liver, kidney, muscle). Thermal damage assessed by measuring depth of damage at minimum, default, and maximum power settings using histology. | Thermal effects are comparable and safe. |
| Usability | Usability testing per IEC 62366-1, including device assembly, disassembly, reprocessing, and application in a simulated environment. | Usable and safe in simulated use scenarios. |
| Overall Conclusion | "The results of these tests indicate that the EasyInstruments are substantially equivalent to the predicate devices." "The equivalent indications for use, technological characteristics, and performance characteristics for the proposed EasyInstruments are assessed to be substantially equivalent to the predicate devices." "The subject device does not raise new issues of safety or efficacy compared to the predicate devices." | Substantially equivalent to predicate devices in safety and efficacy. |
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 test set: Not explicitly specified for each test. For "Thermal effects on tissue," it mentions "ex vivo animal tissues (liver, kidney, and muscle)," implying a sample of tissue, but the quantity is not detailed. For bench performance, it refers to "disposable tips," "reusable tips," "EasyHandle," and "EasyShaft," suggesting multiple units were tested, but precise numbers are not provided.
- Data provenance: Not specified. The manufacturer is based in Austria, but the location where the tests were specifically conducted or the origin of the animal tissues is not stated. The tests are non-clinical (bench, ex vivo).
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)
Not applicable. This document pertains to the 510(k) clearance of electrosurgical instruments (hardware), not an AI/software device that requires expert-established ground truth for image interpretation or diagnosis. The "ground truth" here related to performance testing (e.g., measurements of thermal damage, visual inspection criteria, electrical readings), not clinical diagnoses.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable, for the same reasons as #3. Adjudication methods are typically used in clinical studies involving interpretation of medical data, where there might be disagreement among experts.
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/software device, so no MRMC study or AI assistance evaluation 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/software device.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
For the non-clinical performance and thermal effects testing, the "ground truth" would be established by:
- Engineering specifications and standards (e.g., for electrical safety, dimensions, opening angles, grasping strength, continuity checks).
- Histological assessment for thermal damage (directly observing tissue changes).
- Standardized methods for cleaning/sterilization efficacy.
- Biocompatibility test results against established safety limits.
8. The sample size for the training set
Not applicable. This is not an AI/software device that requires a training set.
9. How the ground truth for the training set was established
Not applicable, for the same reasons as #8.

The A.M.I. FiXcision device is intended to be used by qualified physicians to provide access of internal structures and for manipulating soft tissue (cutting) for treatment of simple anal fistulae.
FiXcision is an EO-sterilized, single use, multi-part, manual cutting instrument for use during anal fistula surgery in coloproctology. FiXcision enables circumferential tissue removal for the treatment of simple anal fistulae. The four components include the following:
- Probe: Component made of stainless steel that passes through the fistula tract.
- Guide: Component made of stainless steel that compresses tissue within the fistula tract.
- Base Plate: Component made of stainless steel that acts as a stop for the Circular Cutter.
- Circular Cutter: Component made of stainless steel and polyvinyl chloride (PVC-U). The Circular Cutter cuts tissue from fistula tract. The distal end of the Circular Cutter has a protective cap made of silicone that is removed prior to use.
The provided text describes a medical device called FiXcision, a manual cutting instrument for use during anal fistula surgery. However, the text does not contain information about acceptance criteria for device performance, nor does it describe a study that proves the device meets such criteria.
The document discusses:
- Indications for Use: The A.M.I. FiXcision device is intended to be used by qualified physicians to provide access to internal structures and for manipulating soft tissue (cutting) for the treatment of simple anal fistulae.
- Device Description: It's an EO-sterilized, single-use, multi-part, manual cutting instrument consisting of a Probe, Guide, Base Plate, and Circular Cutter.
- Predicate Device: K760715, Flexible Cutting Scissors / V. Mueller O.V. Baxter Healthcare Corp.
- Summary of Non-Clinical Testing:
- Sterilization and shelf life validation
- Biocompatibility testing (Cytotoxicity, Sensitization, Irritation per ISO 10993-5 and 10993-10)
- Performance testing (bench):
- Design validation: Wear of the cutting edge, Tensile force of the Circular Cutter, Bending test for the Probe, Strength of screwed end of the Guide.
- Usability per IEC 62366-1
The text explicitly states: "No FDA performance standards have been established for FiXcision." Therefore, there are no acceptance criteria, and consequently, no study described to prove the device meets them, in the typical sense of clinical performance metrics like sensitivity, specificity, or accuracy.
The non-clinical testing performed is to demonstrate equivalence to the predicate device and ensure safety and basic functionality, not to establish performance against specific acceptance criteria for diagnostic or treatment effectiveness.
Therefore, I cannot populate the requested table or answer the specific questions regarding acceptance criteria and performance studies because that information is not present in the provided document. The document focuses on regulatory clearance based on substantial equivalence to a predicate device through non-clinical testing.

The Wi-3 HAL-RAR System is a Bluetooth-enabled, pulsed Doppler, ultrasound system intended to be used for detecting hemorrhoidal arteries, manually ligating these arteries, and subsequently carrying out a mucopexy of hemorrhoidal prolapse if necessary.
The Wi-3 HAL-RAR System is a Bluetooth-enabled, pulsed Doppler, ultrasound system intended to be used for detecting hemorrhoidal arteries, manually ligating these arteries, and subsequently carrying out a mucopexy of hemorrhoidal prolapse if necessary. "HAL" is an acronym referring to "Hemorrhoidal Arteries Ligation", and "RAR" is an acronym referring to "Recto Anal Repair." The Wi-3 HAL-RAR System is designed for use in a surgical suite or operating room.
The Wi-3 HAL-RAR System includes components that come in contact with the patient during use. The RAR Probes (made of acrylic-based multipolymer) and Sleeve (PBT) are external communicating devices having limited contact duration (< 24 hours) with tissue. The Wi-3 Arm (made of Aluminum Alloy) and Wi-3 Fixation Nut (made of polyphenylsulfone and acetal) are surface devices having limited contact duration (< 24 hours) with skin.
This document is a 510(k) premarket notification for the Wi-3 HAL-RAR System and primarily focuses on establishing substantial equivalence to predicate devices, rather than presenting a detailed study proving the device meets specific acceptance criteria in the manner requested. The document outlines non-clinical testing performed, but does not provide specific acceptance criteria or performance results in a quantifiable way for clinical efficacy.
Therefore, many of the requested elements for describing acceptance criteria and a study proving device performance cannot be extracted from this document.
Here's what can be extracted:
1. A table of acceptance criteria and the reported device performance
This information is not provided in the document. The document states that "non-clinical testing" was performed, but does not specify acceptance criteria or quantitative performance results for clinical efficacy. The types of non-clinical tests mentioned are:
- Biocompatibility: Compliant to ISO 10993-1.
- Software Verification: Compliant to IEC 60601-1 and IEC 60601-1-4.
- Electromagnetic Compatibility and Electrical Safety: Compliant to IEC 60601-1-2 and IEC 60601-2-37.
For these non-clinical tests, the "reported device performance" is simply that the device was found to be "in compliance" or "tested in compliance" with the stated standards. No specific performance metrics or quantitative results are given.
2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
Not applicable. The document discusses non-clinical testing of the device itself (biocompatibility, software, electrical safety) rather than clinical performance data from a test set of patient data.
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)
Not applicable. This document does not describe a study involving expert review for ground truth establishment.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable. This document does not describe a study involving adjudication of a test set.
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 device described, the Wi-3 HAL-RAR System, is a surgical tool for detecting and ligating hemorrhoidal arteries. It is not an AI-based diagnostic tool, and therefore, an MRMC study comparing human reader performance with and without AI assistance is not relevant to this device or document.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. The Wi-3 HAL-RAR System is a physical medical device (ultrasound system for surgery) used by a human operator, not a standalone algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
Not applicable. As noted, the testing described is non-clinical and related to device safety and compliance with standards, not diagnostic or therapeutic efficacy requiring ground truth from clinical data.
8. The sample size for the training set
Not applicable. This document does not describe the development or training of an algorithm using a training set.
9. How the ground truth for the training set was established
Not applicable. This document does not describe the development or training of an algorithm using a training set.
