    Intended Use

    The Disposable Dual Action Tissue Closure Device is intended for use in flexible endoscopy for the compression of tissue in the gastrointestinal tract for adult patient only.

    The Disposable Dual Action Tissue Closure Device is indicated for clip placement within the gastrointestinal tract for the purpose of:

    1. Endoscopic marking:

    2. Hemostasis for:

    a.Mucosal/sub-mucosal defects

    Device Description

    The proposed device Disposable Dual Action Tissue Closure Device is a sterile, single-use endoscopic clipping device, intended to be used in flexible endoscopy for the compression, manipulation of tissue in the gastrointestinal tract. It consists of two main components, delivery system and clip assembly. The proposed devices are EO sterilized to achieve the Sterility Assurance Level (SAL) of 106 and placed in a sterility maintenance package to ensure a shelf life of 3 years.

    AI/ML Overview

    This document outlines the acceptance criteria and supporting studies for the Micro-Tech (Nanjing) Co., Ltd. Disposable Dual Action Tissue Closure Device (K233772).

    1. Table of Acceptance Criteria and Reported Device Performance

    The provided document describes the device as substantially equivalent to a predicate device (K212748) except for one indication and shelf-life, and therefore, directly stated acceptance criteria are not explicitly presented as separate quantitative values for each performance test. Instead, the document relies on demonstrating that the proposed device performs the same or better than the predicate device for all shared characteristics, and that the changes in indications and shelf-life are supported by additional testing or literature.

    Below is a table summarizing the performance data presented, emphasizing the comparison to the predicate device.
