The summary describes a mechanical and electrical device for cutting and lifting tissue, with no mention of AI/ML, image processing for analysis, or data sets for training/testing.
Yes
The device is used to cut tissue and lift mucosal lesions within the digestive tract, which are direct interventions for treating medical conditions.
No
The device is described as an electrosurgical knife for cutting tissue and lifting mucosal lesions, which are interventional procedures, not diagnostic ones.
No
The device description explicitly states it is an "endoscopic electrosurgical knife incorporating the saline feeding function," indicating it is a physical hardware device used for cutting tissue and injecting saline. The performance studies also involve testing the physical cutting and lifting capabilities on ex-vivo tissue.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples such as blood, urine, or tissue that have been taken from the human body to detect diseases or other conditions. They are used to provide information for diagnosis, monitoring, or screening.
- Device Function: The description clearly states that this device is an endoscopic electrosurgical knife used to cut tissue within the digestive tract and induce saline into the submucosa. This is a direct surgical intervention performed in vivo (within the living body), not a test performed on a sample in vitro (outside the living body).
- Intended Use: The intended use is for cutting and lifting tissue during endoscopic procedures, which are therapeutic and diagnostic procedures performed directly on the patient.
- Lack of Diagnostic Testing: There is no mention of analyzing samples, detecting biomarkers, or providing diagnostic information based on laboratory testing.
Therefore, based on the provided information, this device is a surgical instrument used for therapeutic and procedural purposes, not an in vitro diagnostic device.
N/A
Intended Use / Indications for Use
These instruments have been designed to be used with Olympus endoscopes and electrosurgical units to cut tissue within the digestive tract using high-frequency current.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
- Performance testing: Conducted to demonstrate the essential performance of the subject device and confirmed that the subject device works as intended with the compatible devices.
- Test A: A test to evaluate the performance to cut the digestive tract mucosa and compare the result with that of the predicate device. The subject device and the primary predicate device 1 (KD-620LR, K092309) were compared for the equivalency in cutting the ex-vivo porcine digestive tract mucosa (esophagus, stomach, and colon).
- Test B: A test to evaluate the lifting of the digestive tract mucosa and compare the size of mucosal lift with that of the predicate device. The subject device and the predicate device 3 (Hybridknife, K083608) were compared for the equivalency in lifting of the ex-vivo porcine digestive tract mucosa (esophagus, stomach, and colon).
- Test C: A test composed of the test items "cut the mucosa" and "lift the mucosa by induction of saline to the submucosal layer" to compare the degree of thermal damage on the ex-vivo porcine digestive tract (esophagus, stomach, and colon) wall caused by the subject device and that caused by the predicate device 3 (Hybridknife, K083608). The histological study was carried out to evaluate the degree of thermal damage.
- Other performance testing:
- Knife operation with the compatible endoscopes
- Dimension of each part of the knife
- General durability
- Risk analysis: Carried out in accordance with established in-house acceptance criteria based on ISO 14971:2007. The design verification tests and their acceptance criteria were identified and performed as a result of this risk analysis assessment.
- Shelf-life testing: Conducted based on an accelerated aging test in accordance with ASTM F1980-16, the standard guide for accelerated aging of sterile barrier systems for medical devices. Three-year aging test will be performed to demonstrate longer stability and support the results of the accelerated aging test.
- Sterilization validation: Carried out with Methods Half-cycle approach in accordance with ISO 11135:2014.
- Biocompatibility testing: Performed in accordance with the FDA Guidance, Use of International Standard ISO-10993, 'Biological Evaluation of Medical Devices Part 1: Evaluation and Testing within a risk management process' issued on June 16, 2016.
- Electromagnetic compatibility, electric safety, and thermal safety: Had been confirmed.
