The OCS™ Lung Donor Flush Set is a single-use device indicated for hypothermic flushing and replacement of residual blood in donor lungs with a legally marketed organ preservation solution at the time of organ removal from the donor during the preparation of these organs for transplantation.

Device Description

The OCS Lung Donor Flush Set is a sterile single-use device indicated for hypothermic flushing and replacement of residual blood in donor lungs with a legally marketed organ preservation solution at the time of organ removal from donor during the preparation of these organs for transplantation. It is comprised of an already 510(k) cleared cannula (K132811, Sarns Soft-Flow Extended Aorta Cannula) along with the donor flush lines subassembly. The donor flush line assembly consists of silicone tubing, clamps and two spike connectors to enable connection between donor lungs and bags of organ preservation solution. The clamps are used to control the gravity flow of solution from bags to the donor organ.

The device is sterilized by ethylene oxide and is provided in a Tyvek pouch packaged in a corrugated box.

AI/ML Overview

The provided FDA 510(k) summary document for the TransMedics, Inc. OCS™ Lung Donor Flush Set focuses on establishing substantial equivalence to a predicate device for medical device clearance, not on providing a study proving a device meets specific clinical performance acceptance criteria in the context of an AI/algorithm-based device.

Therefore, many of the requested sections (e.g., sample size for test set, number of experts, adjudication method, MRMC study, standalone performance, training set details) are not applicable as they pertain to the evaluation of AI or algorithmic performance, which is not the subject of this medical device submission.

The document describes a physical medical device used for organ preservation, not an AI or software-driven diagnostic or treatment tool. The "performance data" section refers primarily to bench testing, biocompatibility, sterilization, and shelf-life, which are standard for physical medical devices.

Here's an attempt to answer the questions based only on the provided document, noting where information is not available or not applicable:


Acceptance Criteria and Study for the OCS™ Lung Donor Flush Set

This document describes the 510(k) submission for the OCS™ Lung Donor Flush Set, a physical medical device. The "study" referenced in the document is primarily bench testing to verify product requirements, not a clinical trial or AI performance study.

1. Table of Acceptance Criteria and Reported Device Performance

The document states: "Performance testing was done to verify that OCS Lung Donor Flush Set meets all of its product requirements. The testing demonstrated that all acceptance criteria were met and that the OCS Lung Donor Flush Set was acceptable for clinical use."

However, the specific "acceptance criteria" (e.g., tensile strength, flow rate, leak integrity) and the detailed results of "reported device performance" are not explicitly listed in the provided 510(k) summary. These details would typically be found in the full submission, but are summarized as met for the purpose of demonstrating substantial equivalence.

Acceptance Criteria CategoryReported Device Performance
BiocompatibilityAcceptable, based on components from PMA-approved or 510(k)-cleared devices.
Sterility Assurance Level10⁻⁶ (stated as met).
Shelf Life26 months (labeled as met).
Bench TestingAll product requirements and acceptance criteria were met. (Specific criteria and results not detailed in this summary).

2. Sample Size Used for the Test Set and Data Provenance

Not applicable in the context of an AI/algorithm test set. The "test set" for this physical device was likely a series of units manufactured for bench testing. The document does not specify the number of units tested. The data provenance would be from internal lab testing by TransMedics, Inc.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications

Not applicable. This is not an AI/diagnostic device that requires expert ground truth for image or data interpretation.

4. Adjudication Method for the Test Set

Not applicable. (See #3)

5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study Was Done

No, a multi-reader multi-case (MRMC) comparative effectiveness study was not done. This type of study is relevant for diagnostic imaging or AI systems where human readers interpret cases. The OCS™ Lung Donor Flush Set is a physical device for organ preservation.

6. If a Standalone (i.e. algorithm only without human-in-the loop performance) Was Done

Not applicable. The device is a physical medical device, not an algorithm.

7. The Type of Ground Truth Used

The "ground truth" for this device is its adherence to engineering specifications, material properties, and functional performance (e.g., flow rates, leak integrity, sterility) as verified through design verification and validation testing, often against established standards (e.g., ISO for biocompatibility and sterilization). It does not involve expert consensus, pathology, or outcomes data in the context of diagnostic accuracy.

8. The Sample Size for the Training Set

Not applicable. This is not an AI/machine learning device.

9. How the Ground Truth for the Training Set Was Established

Not applicable. (See #8)

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

5. DEVICE DESCRIPTION

The OCS Lung Donor Flush Set is a sterile single-use device indicated for hypothermic flushing and replacement of residual blood in donor lungs with a legally marketed organ preservation solution at the time of organ removal from donor during the preparation of these organs for transplantation. It is comprised of an already 510(k) cleared cannula (K132811, Sarns Soft-Flow Extended Aorta Cannula) along with the donor flush lines subassembly. The donor flush line assembly consists of silicone tubing, clamps and two spike connectors to enable connection between donor lungs and bags of organ preservation solution. The clamps are used to control the gravity flow of solution from bags to the donor organ.

The device is sterilized by ethylene oxide and is provided in a Tyvek pouch packaged in a corrugated box.

INTENDED USE/INDICATIONS FOR USE 6.

The OCS Lung Donor Flush Set is a sterile single-use device indicated for hypothermic flushing and replacement of residual blood in donor lungs with a legally marketed organ preservation solution at the time of organ removal from donor during the preparation of these organs for transplantation.

SUBSTANTIAL EQUIVALENCE 7.

Comparison of Indications

The OCS Lung Donor Flush Set has an indication for use statement that is identical to the predicate device (Bridge to Life Ltd Cannula for Organ Perfusion) with the exception of additional explanatory text at the end of the predicate device indication, which is not necessary for an indication for use statement and the limitation that the OCS Lung Donor Flush Set is indicated for donor lungs, while the predicate device is indicated for general donor organs.

Like the predicate device, the OCS Lung Donor Flush Set is indicated for hypothermic flushing and replacement of residual blood in donor organs with a legally marketed organ preservation solution at the time of organ removal from donor during the preparation of these organs for transplantation.

Technological Comparisons

The technological characteristics of the subject device are nearly identical to the predicate device. The main difference is that the OCS Lung Donor Flush Set includes the donor flush lines subassembly to facilitate connection between the preservation and the donor lung, while the user must utilize off-the-shelf tubing and connectors for the predicate device. This difference is simply an added convenience for the user and does not impact on safety or substantial equivalence.
