ISolate® is a density gradient medium designed to separate the motile fraction of sperm from seminal fluid. As a two-layer gradient system, it effectively reduces cellular contaminants such as dead sperm, white blood cells and miscellaneous debris. The resulting sample contains predominantly motile sperm. It is intended for use as a human sperm separation medium, to concentrate and purify viable sperm, prior to in vitro fertilization, and related assisted reproductive technology, procedures.
The products are a colloidal suspension of silica particles that have been covalently modified with hydrophilic silane. The colloid is formulated in a buffered physiological solution, compatible with human sperm. They are identical to the predicate device, in formulation and differ only in the intended use.
ISolate Concentrate and ISolate Stock Solution differ only from each other, and from the predicate, in the concentration of the colloidal silica in the formulation. ISolate Stock Solution, is, in fact, identical to the "lower layer" component of the two layer kits. They are provided for those laboratories that wish to use either a two-layer gradient with densities of their own choice, or a single gradient procedure. ISolate Concentrate is designed for further dilution by the user, into an appropriate density gradient. ISolate Stock Solution may be used as supplied, for those laboratories who choose to use a single density procedure, or may be diluted to densities of the laboratory's choice.
Here's a breakdown of the acceptance criteria and study information based on the provided document:
The document describes the submission of ISolate® Concentrate and ISolate® Stock Solution for an expanded intended use to include sperm processing procedures prior to in vitro fertilization. The primary method of demonstrating substantial equivalence is by comparing these new products to a predicate device, ISolate 2-layer kits (cleared under K971809).
1. Table of Acceptance Criteria and Reported Device Performance
| Acceptance Criteria (Performance Measure) | Reported Device Performance (ISolate Concentrate vs. Predicate) | Basis of Comparison |
|---|---|---|
| Sperm survival | Performed comparably | Clinical comparison |
| Forward progression | Performed comparably | Clinical comparison |
| Percent recovery of motile sperm | Performed comparably | Clinical comparison |
Note: The document explicitly states: "ISolate Concentrate has been compared clinically to ISolate 2-layer kits, and has been found to perform comparably in sperm survival, forward progression and percent recovery of motile sperm." The "acceptance criteria" here are implied to be "comparable performance" to the predicate device in these specific metrics. For ISolate Stock Solution, the acceptance criterion is being "identical" to the "Lower Layer" component of the predicate.
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size: The document does not specify the sample size used for the clinical comparison.
- Data Provenance: Not specified (e.g., country of origin, retrospective or prospective). It is simply referred to as a "clinical comparison."
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
- This information is not provided in the document. The document describes a "clinical comparison" but does not detail the methodology for assessing sperm parameters or the experts involved in establishing ground truth for the comparison.
4. Adjudication Method for the Test Set
- This information is not provided in the document.
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
- No, an MRMC comparative effectiveness study was not done. This document pertains to a medical device (sperm separation media), not an AI-powered diagnostic or assistive tool. Therefore, the concept of "human readers improve with AI" is not applicable here.
6. If a Standalone (i.e. algorithm only without human-in-the loop performance) was done
- No, a standalone (algorithm only) performance study was not done. This document describes a medical device (sperm separation media), not a standalone algorithm. Its performance is evaluated based on its ability to separate sperm, which is a chemical/physical process.
7. The Type of Ground Truth Used (expert consensus, pathology, outcomes data, etc.)
- The ground truth for the clinical comparison appears to be based on direct measurements of sperm parameters: "sperm survival, forward progression and percent recovery of motile sperm." These measurements would typically be performed by laboratory technicians or embryologists using established laboratory protocols, rather than expert consensus on images or pathology.
8. The Sample Size for the Training Set
- Not applicable. This device is a chemical medium, not a machine learning algorithm that requires a training set.
9. How the Ground Truth for the Training Set was Established
- Not applicable. As stated above, this is not an AI/machine learning device.

The electrosurgical probes and devices are to be used with commercially availbale R.F. Generators, endoscopes, and suction/irrigation sytems. These devices can be used for laparoscopic, hysteroscopic, endoscopic and open surgical procedures designed for soft tissue removal using coagulation/ablation/vaporization mode of R.F. energy.
Isolated Electrosurgical Probe/Device-Salinetrode
The provided document is a 510(k) clearance letter from the FDA for an electrosurgical device (Salinetrode™) from February 1998. It primarily addresses the regulatory status (substantial equivalence) of the device to previously marketed predicate devices.
This type of document (a 510(k) clearance letter) does not contain the detailed technical study information you are asking for.
Specifically, a 510(k) clearance letter:
- Does not include acceptance criteria for device performance. It confirms that the device is "substantially equivalent" to a predicate device, meaning it has the same intended use and technological characteristics, or different characteristics that do not raise new questions of safety and effectiveness.
- Does not include specific study data, sample sizes, expert qualifications, or ground truth methodologies. These details would be found in the 510(k) submission itself, which is typically a much more extensive document that includes performance data, bench testing, and potentially clinical studies, depending on the device and its risk profile.
- Does not discuss multi-reader multi-case (MRMC) studies or standalone algorithm performance, as this device is a physical electrosurgical probe, not an AI/software device.
Therefore, I cannot provide the requested information based on the input text. The document only confirms the device's regulatory clearance based on substantial equivalence, not its specific performance metrics or the studies backing them up.

The product is intended for use in the preparation of human sperm for intrauterine insemination (IUI).
The product is a colloidal suspension of silica particles which have been covalently modified with hydrophilic silane. The colloid is formulated in a buffered physiological solution compatible with human sperm. The product is packaged in two formats. One format consists of a kit of two solutions which differ only in the concentration of the colloidal silica, and therefore in their density. The two solutions, labeled "Upper" and "Lower", are utilized to form a step-gradient in a centrifuge tube. The other product format is a single solution which can be utilized as a "stock solution" to create a different step gradient from that provided by the kit. This latter solution is identical to the "Lower" (i.e., higher density) solution.
The provided text does not contain detailed acceptance criteria with numerical targets. Instead, it describes a "substantial equivalence" study where the performance of the ISolate device was compared against predicate devices.
Here's an analysis based on the provided text, addressing as many of your points as possible:
Acceptance Criteria and Study Details for ISolate Sperm Separation Medium
1. Table of Acceptance Criteria and Reported Device Performance
| Acceptance Criteria (Implied) | Reported Device Performance |
|---|---|
| Substantial equivalence to predicate devices (Sperm Select and Modified Ham's F-10) in sperm preparation for IUI. | "The results showed that sperm prepared with ISolate resulted in preparations which were substantially equivalent to those from the predicate devices." |
| Performance metrics for sperm preparation (e.g., recovery, motility, viability, forward progression, normal forms) comparable to predicate devices. | "The resulting purified sperm preparations were assayed for recovery, motility, viability, forward progression and normal forms." (Results explicitly stated as "substantially equivalent".) |
| Biocompatibility | Concluded to be substantially equivalent to predicate devices. |
Note on Acceptance Criteria: The document indicates that the device was deemed "substantially equivalent" to predicate devices, which is the primary criterion for 510(k) clearance in the US. Specific numerical targets for performance metrics (recovery, motility, etc.) are not provided in this summary. The "acceptance criteria" here are implied to be "no worse than" or "comparable to" the predicate devices for the specified performance metrics.
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size: The exact number of semen samples (fresh and cryopreserved) used in the performance study is not specified in this summary. It only states "Semen samples (fresh and cryopreserved) were processed...".
- Data Provenance: The document does not specify the country of origin of the data. It is a 510(k) submission to the US FDA, so the data would typically be expected to originate from studies conducted in a manner acceptable for US regulatory review. The study appears to be prospective in the sense that fresh and cryopreserved samples were processed "in parallel" using ISolate and predicate devices for comparison.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
- This information is not provided in the summary. The evaluation of sperm parameters (recovery, motility, viability, etc.) would typically be performed by trained lab personnel rather than "experts" in the context of ground truth establishment for diagnostic algorithms.
4. Adjudication Method for the Test Set
- This information is not applicable and therefore not provided. "Adjudication method" typically refers to resolving discrepancies in expert interpretations, which is not relevant for objective laboratory measurements of sperm parameters.
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
- No. This type of study (MRMC for AI assistance) is not applicable to this device. ISolate is a sperm separation medium, a laboratory reagent, not an AI-powered diagnostic device or image analysis software.
6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) Was Done
- No. This concept is not applicable to this device. ISolate is a medium used in a laboratory procedure; there is no "algorithm" in the sense of a software-based diagnostic tool. The performance evaluation was of the chemical medium itself in processing sperm samples.
7. The Type of Ground Truth Used
- The ground truth was established by objective laboratory measurements of various sperm parameters: recovery, motility, viability, forward progression, and normal forms. These metrics represent the direct, measurable outcomes of the sperm separation process.
8. The Sample Size for the Training Set
- Not applicable. This device does not involve a "training set" in the context of machine learning or AI. It is a chemical product; its performance is based on its physical and chemical properties and how it interacts with biological samples, not on an algorithm trained on data.
9. How the Ground Truth for the Training Set Was Established
- Not applicable. As stated above, there is no "training set" for this type of device.
