An occluder balloon is used to maintain pneumoperitoneum during the procedure.
The Advincula Delineator Uterine Manipulator is available with Koh-Cups sized 2.5cm or 4.0cm in diameter. The Koh-Cup is made of Hytrel and the manipulator is made of stainless steel, silicone, various plastics, adhesives and inks. The subject device is intended to be used in hospitals.
This document describes the premarket notification (510(k)) for the Advincula Delineator™ Uterine Manipulator, which is a medical device and not an AI/ML powered device. As such, it does not involve the type of acceptance criteria and study designs typically associated with AI/ML device performance (e.g., sensitivity, specificity, MRMC studies, ground truth established by experts).
The acceptance criteria presented here are for the substantial equivalence of a modified medical device to a predicate device, focusing on material changes and packaging, rather than an AI algorithm's diagnostic or predictive performance.
Therefore, the requested information, specifically regarding AI/ML device performance, acceptance criteria, test set details, expert involvement, and ground truth methodologies, cannot be extracted from this document as it is not relevant to the described device and its review process.
Instead, the document focuses on:
-
Acceptance Criteria (for device modification equivalence): The "acceptance criteria" here refer to demonstrating that changes made to the device (specifically, the Koh-Cup material and packaging) do not raise new questions of safety or effectiveness compared to the predicate device.
- The criteria are met by passing a series of non-clinical performance tests.
-
Study Proving Acceptance Criteria Met: The study undertaken was a series of non-clinical performance tests on the modified device.
Here's a breakdown of the relevant information provided in the document:

2. Sample Size Used for the Test Set and Data Provenance
The document does not explicitly state the numerical sample size
for each test (e.g., number of devices tested in the pull-off or compression tests). However, it implies testing was performed on a sufficient number of devices to demonstrate the device meets acceptance criteria.
- Data Provenance: The tests are explicitly non-clinical performance and design validation tests on the physical device itself. The "cadaveric model" implies testing was performed using human cadavers.
- Country of Origin of the Data: Not specified, but likely performed by or for CooperSurgical, Inc. in the US.
- Retrospective or Prospective: These are prospective tests performed specifically for regulatory submission.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications
N/A. This is a physical device, not an AI/ML system requiring expert interpretation or ground truth establishment in a diagnostic context. The "ground truth" here is the physical performance of the device against engineering specifications.
4. Adjudication Method for the Test Set
N/A. Adjudication methods like 2+1 or 3+1 are relevant for subjective interpretations (e.g., in medical image reading). For objective engineering tests (pull-off, compression, biocompatibility), the results are typically quantitative and directly measured against a specification.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was Done
No. An MRMC study is not applicable to a uterine manipulator. These studies are typically performed to assess the impact of AI on human reader performance for diagnostic tasks.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was Done
No. This a physical medical device, not an algorithm.
7. The Type of Ground Truth Used
The "ground truth" for this device's performance is based on engineering specifications, material science principles, and established biocompatibility standards (e.g., ISO 10993). For the design validation, the "ground truth" was the device "performs as intended and meets user needs" in a cadaveric model, which would be an outcome-based assessment in a simulated use environment.
8. The Sample Size for the Training Set
N/A. This term is applicable to AI/ML models. For a physical device, the concept of a "training set" is not relevant in the same way. The design and manufacturing processes are iterative, but there's no defined "training set" as in machine learning.
9. How the Ground Truth for the Training Set was Established
N/A. As above, this concept doesn't apply to this kind of device.

CooperSurgical Advincula Delineator Uterine Manipulator
The CooperSurgical Advincula Delineator™ Uterine Manipulator is indicated to provide delineation of the vaginal fornices and maintain pneumoperitoneum as a uterine manipulator during Total Laparoscopic Hysterectomy (TLH), Laparoscopic Assisted Vaginal Hysterectomy (LAVH) and/or Laparoscopic Supra-Cervical Hysterectomy (LSH).
The CooperSurgical Advincula Delineator™ Uterine Manipulator is a single use device, supplied sterile to the end user. It includes a cup shaped sliding colpo-pneumo occluder used to delineate the vaginal fornices, providing an anatomical marker to facilitate resection of the uterus, and a balloon to occlude the vaginal vault to maintain pneumoperitoneum during uterine resection.
The provided document is a 510(k) summary for the CooperSurgical Advincula Delineator™ Uterine Manipulator. It focuses on demonstrating substantial equivalence to a predicate device, rather than providing detailed acceptance criteria and a study to prove a device meets those criteria from an AI/algorithm performance perspective.
Therefore, many of the requested categories (e.g., sample size for test set, number of experts for ground truth, MRMC study, sample size for training set, how ground truth for training set was established) are not applicable to this type of medical device submission. This document describes a physical medical device, not an AI or algorithmic device.
However, I can extract the relevant performance data and conclusions presented in the document based on the provided text.
Here's a breakdown of the information that is available in the document, formatted as requested where possible:
1. Table of Acceptance Criteria and Reported Device Performance
The document does not explicitly state "acceptance criteria" in a quantitative manner as one would for an AI algorithm (e.g., "sensitivity must be > 90%"). Instead, performance assessments were conducted to ensure the device performs comparably to its predicate and is safe and effective. The "acceptance" is implied by demonstrating substantial equivalence.
Performance Characteristic | Acceptance Criteria (Implied by Substantial Equivalence) | Reported Device Performance |
---|---|---|
Vaginal Occlusion (Pneumoperitoneum) | The vagianl occluder balloon should maintain an adequate inflation capacity to create and maintain pneumoperitoneum, similar to the predicate device, and the difference in inflation capacity should not affect safety or effectiveness. The maximum inflation pressure should be the same as the predicate device. Burst volume testing should confirm safety. (Predicate: 90-120cc inflation capacity, same maximum inflation pressure, burst volume testing). | Subject Device: Occluder balloon with inflation capacity of 60-120cc. Predicate Device: Occluder balloon with inflation capacity of 90-120cc. Performance: The document states, "The primary technological difference between the subject and predicate devices is the inflation capacity of the vaginal occluder balloon. However, this minor difference does not raise different questions of safety or effectiveness as the maximum inflation pressure is the same for both the subject and predicate devices. In addition, burst volume testing was conducted to demonstrate that the difference in inflation pressure does not affect the safety and effectiveness of the subject device." The specific "burst volume" results are not detailed in this summary, but the conclusion is that the difference is acceptable. |
Biocompatibility | Patient-contacting components must meet biocompatibility standards appropriate for their contact classification (external communicating, tissue/bone/dentin, ≤ 24 hours). | Components "have been evaluated for biocompatibility as appropriate for their contact classification." (Claimed as "Substantially Equivalent") |
Sterilization & Shelf Life | Must achieve a Sterility Assurance Level (SAL) of 10-6 and have a confirmed shelf life. | Subject Device: Sterilized by ETO to an SAL of 10-6, with an initial shelf life of 1 year. Predicate Device: Sterilized by ETO gas to an SAL of 10-6, with a shelf life of 2 years. (Claimed as "Substantially Equivalent," implying the 1-year shelf life is acceptable). |
Distal & Proximal Balloon Burst Volume | Balloons must withstand appropriate pressure/volume without bursting, comparable to the predicate. | Testing was conducted. The conclusion is that the difference in inflation capacity (which relates to burst volume) does not affect safety and effectiveness. (Details not provided in this summary, but implied satisfactory). |
Distal & Proximal Balloon Leakage | Balloons must not leak when inflated. | Testing was conducted. (Details not provided in this summary, but implied satisfactory). |
Distal & Proximal Balloon Fill Tube Tensile Strength | Fill tubes must have adequate tensile strength. | Testing was conducted. (Details not provided in this summary, but implied satisfactory). |
Tube Bending, Compression, Tension Forces | The device tube must withstand anticipated forces during surgical use without failure. | Testing was conducted. (Details not provided in this summary, but implied satisfactory). |
Security of Sliding Colpo-Pneumo Occluder | The occluder must remain securely locked once positioned. | Testing was conducted. (Details not provided in this summary, but implied satisfactory). |
