The HTS System is an adjunctive audio vessel landmarking aid for use during hemorrhoidal artery treatment. It is not recommended for fetal or ophthalmic use.

The HTS System is an adjunctive audio vessel landmarking aid for use during hemorrhoidal artery treatment. It is not recommended for fetal or ophthalmic use. Doppler audio sounds are heard when the transducer is positioned directly over a hemorrhoidal artery. Cessation of Doppler sounds occurs when ligation of the identified vessel has been completed successfully. Acoustic output values for this transducer are lower than the maximum pre-amendment intensities specified for "Peripheral Vessel" and "Fetal Imaging and Other" applications. There is only one transducer available with this system. The System includes disposable/single use accessories which can be used to perform the manual ligation of the hemorrhoidal arteries.

The provided text is a 510(k) summary for the MedChannel HTS System. It primarily focuses on demonstrating substantial equivalence to predicate devices and adherence to relevant standards rather than presenting a performance study with acceptance criteria in the way one might find for an AI/ML device.

Here's an analysis of the document regarding acceptance criteria and study information, addressing the points you requested:

1. Table of Acceptance Criteria and Reported Device Performance

The document does not provide a table of acceptance criteria for a specific performance study of the MedChannel HTS System itself, nor does it report specific device performance metrics in numerical fashion against such criteria.

Instead, the "Summary of Standards Achieved" section lists regulatory and quality standards that the device complies with, implying that meeting these standards constitutes "acceptance." These are predominantly related to safety, manufacturing quality, and general medical device characteristics.

The "substantially equivalent" determination is the primary "acceptance criterion" met by this 510(k) submission.

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

The document does not describe a specific performance test set with a sample size or data provenance (e.g., country of origin, retrospective/prospective clinical data) for the MedChannel HTS System. The submission relies on demonstrating substantial equivalence to already marketed predicate devices and compliance with general safety and performance standards.

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

This information is not present in the document, as there is no described performance study involving a test set and ground truth established by experts.

4. Adjudication Method for the Test Set

Since no specific test set or performance study is described, there is no information on an adjudication method.

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

No MRMC comparative effectiveness study is mentioned or described in this 510(k) summary. The device, an "adjunctive audio vessel landmarking aid" using Doppler sounds, is not an AI/ML diagnostic interpretation system that would typically undergo such a study to compare human readers with and without AI assistance.

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

The MedChannel HTS System is described as an "adjunctive audio vessel landmarking aid." Its function is to provide real-time audio feedback to a human surgeon during a procedure. It is inherently a "human-in-the-loop" device. Therefore, a "standalone algorithm only" performance study, as typically understood for AI devices, would not be applicable and is not mentioned. Its performance is tied to its utility in aiding a human operator.

7. The Type of Ground Truth Used

Given the nature of the device and the content of the 510(k) summary, explicit "ground truth" (like pathology or outcomes data) for a specific performance study of the HTS system itself is not discussed. The ground truth for its intended use would be the actual presence and successful ligation of hemorrhoidal arteries, which is confirmed clinically during the procedure, but this is not referred to as a "ground truth" in the context of a study within this document. The submission focuses on the device's technical specifications and safety profile, arguing its substantial equivalence to other devices, which implies its ability to contribute to successful outcomes.

8. The Sample Size for the Training Set

The document does not describe a training set or its sample size. This type of submission does not involve machine learning algorithms that require training data.

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

Since no training set is discussed, there is no information on how its ground truth would be established.

In summary:

This 510(k) summary for the MedChannel HTS System is a traditional submission focused on demonstrating substantial equivalence to predicate devices and adherence to recognized safety and quality standards (e.g., ISO, AAMI, IEC, NEMA). It pre-dates the common requirements for detailed performance studies with acceptance criteria, test sets, ground truth establishment, and AI/ML specific evaluations (like MRMC or standalone performance) that are now typical for modern AI-powered medical devices. The "acceptance" of this device is based on its compliance with these foundational standards and its similarity to existing, legally marketed ultrasound devices.

Ask a specific question about this device

The EasyTac Anchor and delivery system is indicated for approximation of soft tissues and fixation of surgical mesh to tissues during laparoscopic surgical procedures such as hernia repair.

The EasyTac Anchor device is an endoscopic or open surgical stapler composed of a disposable delivery instrument and resorbable fixation devices. The EasyTac Anchor Delivery System consists of an ergonomic handle, trigger, locking and unlocking mechanism, totation knob, shaft containing a cartridge of five to fifteen fixation devices, and retractable hollow needle.

The provided text is a 510(k) summary for the MedChannel EasyTac Anchor, a medical device. This document is a premarket notification to the FDA to demonstrate substantial equivalence to a legally marketed predicate device, rather than a study proving the device meets specific acceptance criteria through a clinical trial or performance study comparing it against a predefined set of metrics.

Therefore, the document does not contain the information requested regarding detailed acceptance criteria, a specific study proving the device meets those criteria, sample sizes for test/training sets, expert ground truth establishment, adjudication methods, or MRMC comparative effectiveness study results.

The 510(k) summary focuses on:

• Intended Use & Indications: For approximation of soft tissues and fixation of surgical mesh during laparoscopic surgical procedures like hernia repair.
• Description: An endoscopic/open surgical stapler with a disposable delivery instrument and resorbable fixation devices.
• Predicate Devices: Lists one predicate device, "Trannon," but no specific performance data for comparison is provided.
• Standards Achieved: Mentions compliance with FDA Quality Systems Regulation (21 CFR § 820), ISO 10993:1 (biological evaluation), AAMI 11135 (sterilization), and ISO 13485 (quality management).

The core of a 510(k) submission is to assert "substantial equivalence" to a predicate device, as explicitly stated in the summary: "In summary, the MedChannel EasyTac Anchors are substantially equivalent to legally marketed devices. Quality System Controls assure the device is substantially equivalent to the predicate devices with respect to its performance, safety, and effectiveness." This means the device relies on the established safety and effectiveness of its predicate, rather than presenting a new study with explicit acceptance criteria for performance.
