Continuous Single Culture™ Complete is intended for use as a culture medium for human gametes and embryos from fertilization through day 5/6 of development in vitro.

Device Description

The Continuous Single Culture™ Complete is based upon the Single Step Medium™ (K072609) formulation that is supplemented with Human Serum Albumin, H.S.A. The Continuous Single Culture™ Complete is composed of a balanced mixture of salts, amino acids and other nutrients that have been shown to support embryo development. The Continuous Single Culture™ Complete is designed to be used as a culture media for fertilization and for development of embryos until the desired developmental stage (up to 5/6 days). Selected embryos are then moved to an embryo transfer media prior to transfer to the uterus.

The Continuous Single Culture™ Complete is supplied in liquid form, and contains gentamicin sulfate as a preservative and a therapeutic grade of Human Serum Albumin (K983584). Liquid Continuous Single Culture™ Complete is supplied in a fill volume of 20 mL.

Continuous Single Culture™ Complete has utility as a culture medium from fertilization through day 5/6 of development. The fertilized oocyte (zygote) is allowed to grow in the culture dish, supported by a culture medium and an appropriate protein supplement, in a carbon dioxide incubator at 37°C until the desired stage of development is achieved. Selected embryos are then moved to an embryo transfer media prior to transfer to the uterus.

Continuous Single Culture™ Complete is supplied as a ready to use liquid in 20 mL bottles.

AI/ML Overview

Here's an analysis of the provided text, focusing on the acceptance criteria and the study that demonstrates the device meets them:

1. Table of Acceptance Criteria and Reported Device Performance

The acceptance criteria are derived from the product specifications comparison between the proposed device (Continuous Single Culture™ Complete) and the predicate device (Single Step Medium™ K072609). The performance for the proposed device is the criteria it must meet.

Specification	Acceptance Criteria for Continuous Single Culture™ Complete	Reported Device Performance (from "Performance Data" and "Product Specification Comparison")
pH	7.25 - 7.54	Not explicitly stated as a numerical result in the "Performance Data" or "Nonclinical Tests" sections for the new device's testing. However, "pH" is listed as a performed test under "Performance Data" and the "Product Specification Comparison" shows "7.25 - 7.54" for both the predicate and proposed device, implying the proposed device meets this.
Osmolality	260 – 270 mOsm/KgH2O	Similar to pH, osmolality is listed as a performed test, and the "Product Specification Comparison" shows "260 – 270 mOsm/KgH2O" for both, implying the proposed device meets this.
Sterility	Pass	"Sterility" is listed as a performed test, and the "Product Specification Comparison" shows "Pass" for both, implying the proposed device meets this.
Endotoxin	≤ 0.25 EU/mL	"Endotoxin" is listed as a performed test, and the "Product Specification Comparison" shows "≤ 0.25 EU/mL" for both, implying the proposed device meets this.
MEA (Mouse Embryo Assay)	≥ 80% expanded blastocyst at 96 hours	The MEA "assures that the product is functional for its intended use, the support of embryonic growth, and that embryotoxic components are not present in the formulation." The "Product Specification Comparison" states "≥ 80% expanded blastocyst at 96 hours" for the proposed device. The nonclinical test section indicates one-cell MEA was performed at three facilities, and the field evaluations "demonstrate that the Continuous Single Culture™ Complete was "equal" to the proven control medium (predicate device)".
HSSA (Human Sperm Survival Assay)	≥ 70% of original motility at 24 hours	The HSSA "assures that the product is both functional for its intended use with regards to sperm wash procedure and that no sperm-toxic components are present in the formulation." The "Product Specification Comparison" states "≥ 70% of original motility at 24 hours" for the proposed device. The nonclinical test section indicates HSSA was performed on donor specimens at three different test facilities, and the field evaluations "demonstrate that the Continuous Single Culture™ Complete was "equal" to the proven control medium (predicate device)". The predicate device did not have an HSSA specification (NT - Not Tested).
Albumin Recovery Assay	Not explicitly stated with a numerical criterion	Listed under "Additional Information" as a "condition of release," implying it's a test performed but without a specific pass/fail criterion mentioned in this document.
Appearance	Not explicitly stated with a numerical criterion	Listed under "Additional Information" as a "condition of release," implying it's a test performed but without a specific pass/fail criterion mentioned in this document.

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

MEA (Mouse Embryo Assay): The study states that one (1)-cell MEA was performed as part of design validation. It was conducted at three (3) different test facilities. The sample size for embryos or individual tests is not specified beyond "one (1)-cell MEA." The data provenance is not explicitly stated (e.g., country of origin), but it is implied to be non-clinical laboratory testing. The study is prospective in nature, as it is part of design validation and pre-market release testing.
HSSA (Human Sperm Survival Assay): Performed on donor specimens at three (3) different test facilities. The number of donor specimens is not specified. The donor specimens were "initially processed by gradient separation and resulting motile specimens were equally divided." Data provenance is not explicitly stated, but it is implied to be non-clinical laboratory testing using human donor samples. The study is prospective, as it is part of design validation and pre-market release testing.
Other tests (pH, osmolality, sterility, endotoxin, albumin recovery, appearance): These are described as routine quality control tests performed "prior to release to the market" and "as a condition of release." The sample sizes for these tests (e.g., how many batches, how many units per batch) are not specified. The data provenance is internal laboratory testing.

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

This document describes non-clinical performance testing for a cell culture medium. It does not involve human interpretation of medical images or patient diagnoses that typically require expert adjudication for ground truth.
The "ground truth" for the MEA and HSSA is an objective biological outcome (embryo development to blastocyst, sperm motility) measured by laboratory assays. The document doesn't mention expert review for establishing ground truth as it would for, say, a diagnostic imaging device. The "field evaluations" where the product was found "equal" to the control medium imply expert handling and perhaps informal assessment, but not formal "ground truth" adjudication.

4. Adjudication Method for the Test Set

Not applicable. As noted above, this study evaluates a cell culture medium through objective laboratory assays, not a diagnostic device requiring expert adjudication of results.

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 a 510(k) summary for a cell culture medium, not an AI-assisted diagnostic device. There are no "human readers," "AI assistance," or "cases" in the context of an MRMC study.

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

Not applicable. This is a cell culture medium, not an algorithm or AI system.

7. The Type of Ground Truth Used

For the MEA, the ground truth is biological outcome data: achievement of ≥ 80% expanded blastocyst development at 96 hours.
For the HSSA, the ground truth is biological outcome data: ≥ 70% of original sperm motility at 24 hours.
For pH, osmolality, sterility, and endotoxin, the ground truth is instrumental measurement data compared against defined numerical ranges or a "Pass" criterion.

8. The Sample Size for the Training Set

Not applicable. As a non-AI/ML device, there is no "training set." The product's formulation was developed and validated, but not "trained" in the machine learning sense. The development likely involved iterative testing and refinement, but this is distinct from an AI training set.

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

Not applicable, as there is no training set for this type of device.

{1}------------------------------------------------

Purpose:

Purpose of this application is to obtain 510(k) marketing clearance for the Continuous Single Culture™ Complete.

Indication for Use:

Continuous Single Culture™ Complete is intended for use as a culture medium for human gametes and embryos from fertilization through day 5/6 of development in vitro.

Description of the Device:

{2}------------------------------------------------

Continuous Single Culture™ Complete is supplied as a ready to use liquid in 20 mL bottles.

Technological Characteristics:

After allowing the fertilized zygote to develop in vitro in Continuous Single Culture™ Complete, the embryo is removed from the culture dish. It is placed into a fresh dish containing Continuous Single Culture™ Complete. The dish is then returned to the incubator, and the embryo is allowed to continue develop in vitro. If a medium change is desired for embryo culture beyond day 3, after 48 hours of embryo culture (of the fertilized embryos), the embryos should be transferred into a new dish of fresh pre-equilibrated Continuous Single Culture™ Complete. After the desired stage of development is obtained selected embryos are then moved to an embryo transfer media prior to transfer to the uterus

Continuous Single Culture™ Complete is similar to Single Step Medium™ (K072609) it is intended for use in assisted reproductive technology procedures that involve the manipulation of gametes or embryos that is supplemented with a protein such as H.S.A. (K983584),

Performance Data:

Continuous Single Culture™ Complete is assayed by one (1) -cell mouse embryo assay (MEA) prior to release to the market. This assay assures that the product is functional for its intended use, the support of embryonic growth, and that embryotoxic components are not present in the formulation..

Continuous Single Culture™ Complete is also assayed by human sperm survival assay (HSSA) was also performed prior to release to the market. This assay also assures that the product is both functional for its intended use with regards to sperm wash procedure and that no sperm-toxic components are present in the formulation.

In addition, performance testing of the product includes pH, osmolality, sterility, and endotoxin testing. These tests demonstrate quality and the consistency in

{3}------------------------------------------------

each lot of Continuous Single Culture™ Complete that is manufactured. These tests also support the equivalence of the proposed device to the predicate device.

Nonclinical Tests:

One (1) -cell MEA was performed on the Continuous Single Culture™ Complete as part of the design validation. Testing was performed at three (3) different test facilities after continuous culture in Continuous Single Culture™ Complete up to 96 hours.

In addition, HSSA was also performed on donor specimens at three (3) different test facilities. The donor specimens were initially processed by gradient separation and resulting motile specimens were equally divided and the average % motility after 24 hours at 37°C in ambient air was determined as compared to the control.

The field evaluations demonstrate that the Continuous Single Culture™ Complete was "equal" to the proven control medium (predicate device) of Single Step Medium™ (K072609).

Additional Information:

Endotoxin, mouse embryo assay, human sperm survival assay, albumin recovery assay, pH, osmolality, appearance and sterility testing will be performed as a condition of release for Continuous Single Culture™ Complete. Results of all release assays performed will be reported on a lot-specific certificate of analysis, and will be indicated on the labeling.

Conclusion:

The predicate device, Single Step Medium™ (K072609) needs to be supplemented with a protein prior to use and it is a common practice for media to be formulated with a protein for use in ART procedures. Therefore, the addition of HSA to the device would not raise new types of safety of effectiveness questions.
