Intended Use

The Illuminated Mediastinal Access Port is intended to aid the surgeon in direct visualization of the mediastinum and facilitate the introduction and removal of surgical instruments during surgical procedures.

The Illuminated Mediastinal Access Port is specifically indicated for use in the anterior, superior and middle mediastinum.

Device Description

The Illuminated Mediastinal Access Port is a trocar/cannula system used to provide mediastinal surgical access. The device includes a blunt trocar for dissecting tissue planes. The open cannula provides for direct visualization of the surgical space and includes small notches at the rim to anchor sutures.

The base of the cannula has fiber optic bundles incorporated that may be connected to a fiber optic light cable and an endoscopic light source. This enhances lighting and visualization within the access device. The device does not include a light source.

The trocar/cannula access device also includes a handle for connection to a support arm. This allows the mediastinoscope to be held in position so that the surgeon can operate using both hands, without holding or re-positioning the mediastinoscope, and to provide stability for the mediastinoscope during operation.

The entire device is disposable, single use and is provided pre-sterilized.

AI/ML Overview

This document is a 510(k) summary for the Illuminated Mediastinal Access Port, which is a medical device intended to aid surgeons in visualizing the mediastinum and facilitating surgical instrument introduction and removal. The document focuses on demonstrating substantial equivalence to a predicate device, not on presenting a detailed study proving the device meets an explicit set of acceptance criteria.

Therefore, many of the requested details about acceptance criteria, study design, and ground truth are not present in the provided text. The document primarily describes various performance tests conducted to ensure the device's safety and functionality in comparison to a predicate device.

Here's an attempt to extract relevant information and note what is missing based on your request:

1. A table of acceptance criteria and the reported device performance

The document does not explicitly state a table of acceptance criteria with corresponding performance metrics. Instead, it describes general performance tests and states that the device was ensured to meet certain conditions or functions comparably to the predicate.

Acceptance Criteria (Inferred from testing)Reported Device Performance (Summary)
No major deformation under mechanical loadNo major deformation under worst-case mechanical load conditions
No breakage of device partsNo breakage of other parts of the device (specifically fiber optic bundles)
Fiber optic bundles don't pull apartFiber optic bundles don't pull apart under normal conditions of use
Illumination quality verifiedIllumination quality verified following mechanical tests and simulated use testing
BiocompatibilityStudies performed in accordance with ISO 10993-1:2009 for a limited contact duration device
Sterility Assurance LevelSterilized to an SAL of 1x10^-6 using ethylene oxide (validated EO cycle)
Sterile packaging integrityMaintained a sterile barrier over time in shelf life testing

Appropriate incision sizeEstablished appropriate incision size through cadaver testing
Forces on tissue during insertion/extractionEvaluated forces during insertion/extraction in cadaver testing, demonstrated device does not break or is not damaged
Safe light outputSpectral irradiance was "considerably less" than standard light source, indicating safe use

2. Sample size used for the test set and the data provenance

  • Sample Size: Not explicitly stated for any of the individual tests. The document refers to "worst case mechanical load conditions," "normal conditions of use," and "cadaver models," but without specific numbers.
  • Data Provenance: Not explicitly stated (e.g., country of origin). The studies appear to be laboratory-based ("bench" testing), cadaver testing, and potentially internal studies by the manufacturer or a contracted lab. This would typically be considered prospective for the device being tested, but the setting (lab/cadaver) is not a clinical one.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

  • This information is not provided. The term "ground truth" as typically used in AI/diagnostic device studies (e.g., confirmed disease status) is not directly applicable here as this is a surgical access device, not a diagnostic one.
  • For assessments like "appropriate incision size" and ability of surgeons to grip the handle, the document mentions "surgeons" in the cadaver models, but does not specify their number, qualifications, or how their observations were formalized into a "ground truth" or acceptance criterion.

4. Adjudication method for the test set

  • Not applicable as this is not a diagnostic study requiring adjudication of findings. Performance tests were conducted against technical specifications or functional requirements.

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 a diagnostic device involving human readers or AI.

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

  • Not applicable as this is not an AI/algorithm-based device.

7. The type of ground truth used

"Ground truth" in the AI/diagnostic sense is not directly applicable. For this device, the "truth" is based on:

  • Engineering specifications/standards: Mechanical load conditions, durability, sterilization standards (e.g., ISO 10993-1, ANSI/AAMI/ISO 11135-2007).
  • Functional performance: "No major deformation," "illumination quality verified," "maintain sterile barrier."
  • Clinical observation (cadaver): "Appropriate incision size," "forces applied to tissue," surgeon feedback on handle grip. These are observational data points rather than a pre-defined "ground truth."

8. The sample size for the training set

  • Not applicable. This is not an AI/machine learning device that requires a training set.

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

  • Not applicable.

4. Device Description

The Illuminated Mediastinal Access Port is a trocar/cannula system used to provide mediastinal surgical access. The device includes a blunt trocar for dissecting tissue planes. The open cannula provides for direct visualization of the surgical space and includes small notches at the rim to anchor sutures.

The base of the cannula has fiber optic bundles incorporated that may be connected to a fiber optic light cable and an endoscopic light source. This enhances lighting and

{4}------------------------------------------------

visualization within the access device. The device does not include a light source.

The trocar/cannula access device also includes a handle for connection to a support arm. This allows the mediastinoscope to be held in position so that the surgeon can operate using both hands, without holding or re-positioning the mediastinoscope, and to provide stability for the mediastinoscope during operation.

The entire device is disposable, single use and is provided pre-sterilized.

5. Intended Use

The Illuminated Mediastinal Access Port is intended to aid the surgeon in direct visualization of the mediastinum and facilitate the introduction and removal of surgical instruments during surgical procedures.

The Illuminated Mediastinal Access Port is specifically indicated for use in the anterior, superior and middle mediastinum.

Comparison of Technological Characteristics with Predicate 6.

The intended use of the Aegis Surgical Illuminated Mediastinal Access Port is the same as the Richard Wolf Optical Mediastinoscope cleared in K971166.

The principles of operation and operational characteristics are the same and include mediastinal access, surgical instrument passage, visualization and illumination, the ability to spread tissue planes and increase surgical access. Both devices are used in a sterile state.

The devices are different in that the Richard Wolf Optical Mediastinoscope is reusable and able to be re-sterilized between uses. The Aegis Surgical Illuminated Mediastinal Access Port is pre-sterilized and single use. Sterilization to an SAL of 1x10-6 using ethylene oxide was demonstrated via a validated EO cycle.

The two devices are different in that the Richard Wolf Optical Mediastinoscope includes the use of an endoscope while the Aegis Illuminated Mediastinal Access Port provides direct mediastinal visualization but similarly includes illumination by a standard endoscopic light source.

The Illuminated Mediastinal Access Port device and predicate device have differences in the size and shape of the cannula. While both devices provide an open channel for access to the mediastinum and the ability to introduce and utilize surgical instruments through the cannula channel, the predicate device (Richard Wolf Optical Mediastinoscope, K971166) has a narrower channel and instruments are introduced singularly. The Illuminated Mediastinal Access Port device has a wider, trapezoid shaped cannula that allows the clinician to pass multiple instruments through the channel simultaneously. This larger diameter has the ability to improve visualization of the work space and the ability to internally suture as needed.

{5}------------------------------------------------

Another technical difference is the length of the working channel such that the Illuminated Mediastinal Access Device is for use in the anterior, superior and middle mediastinum. Although the two devices have differences in size, the differences do not introduce new or different issues of safety and effectiveness and any possible questions regarding use have been tested using bench or cadaver models to evaluate use and safety.

The handle grip of the Illuminated Mediastinal Access Port device is shorter than that of the predicate device, however, in evaluations of the device in cadaver models, surgeons were able to adequately grip the handle and control the insertion and positioning of the device within the incision. Once positioned, the Illuminated Mediastinal Access Port may be attached to a surgical support arm to provide hands free support and stability during the surgical procedure. More recently marketed versions of the predicate device also include a connection point for connecting to a surgical support arm as displayed in marketing literature.

7. Performance Testing Summary

Like the Richard Wolf Optical Mediastinoscope, the Aegis Surgical Illuminated Mediastinal Access Port was tested to ensure that there was no major deformation of the device when tested under worst case mechanical load conditions.

In addition durability tests were performed to demonstrate that there was no breakage of other parts of the device, specifically the fiber optic bundles were tested and compared to similar medical devices to assure that they do not pull apart under normal conditions of use. The illumination quality was also verified following mechanical tests and simulated use testing.

Biocompatibility studies were performed in accordance with ISO 10993-1:2009 for a limited contact duration device.

Sterilization studies were also performed in accordance with ANSI/AAMI/ISO 11135-2007 "Medical Devices-Validation and routine control of ethylene oxide sterilization" and AAMI TIR 28:2009, "Product adoption and process equivalence for ethylene oxide sterilization" to demonstrate that the Aegis Surgical Illuminated Mediastinal Access Port is able to be ethylene oxide (EO) sterilized to a sterility assurance level of 1x10 6. Shelf life testing was performed to demonstrate that the sterile packaging maintained a sterile barrier over time and to demonstrate that the product functionality was maintained.

Transit testing was performed to demonstrate that the sterile packaging, corrugate box, and outer shipping container were able to adequately withstand the test conditions required for ISTA 2A distribution standards.

Cadaver testing was performed to establish an appropriate incision size and to evaluate the forces applied to tissue during insertion and extraction. Forces in the lateral and axial directions were also evaluated under worst case conditions to demonstrate that the device does not break or is not damaged.

Lastly the Illuminated Mediastinal Access Port was tested with a compatible light source for spectral irradiance under normal and worst case light output conditions. The testing

{6}------------------------------------------------

compared the output of the light source when connected to a standard fiber optic light cable and when connected to a standard fiber optic light cable in tandem with the Illuminated Mediastinal Access Port. The spectral irradiance of the Illuminated Mediastinal Access Port was considerably less than that of the standard light source configuration when tested under both typical clinical and worst case light output conditions, indicating that the Illuminated Mediastinal Access Port is safe for use with standard light sources and light cables.

Conclusion 8.

The Illuminated Mediastinal Access Port has been shown to be equivalent to the predicate in terms of intended use and operation and the risks of any technological differences have been mitigated through testing.
