No
The summary describes a standard electrosurgical instrument and does not mention any AI or ML capabilities, image processing, or data sets for training/testing.
Yes
The device is used for endoscopic treatments such as ablation, incision, cauterization, coagulation, avulsion of tissue, and arrest of bleeding, which are all therapeutic procedures.
No
The intended use describes therapeutic actions such as ablation, incision, cauterization, coagulation, avulsion, and arresting bleeding, and tissue removal. These are interventional treatments, not diagnostic processes.
No
The device description explicitly states it is an "electrosurgical instrument" that uses "high-frequency ('HF') electrical current" and is available with "either a needle or ball tip slitter." This indicates a physical hardware device, not software only. The performance studies also focus on electrical safety, biocompatibility, and sterility, which are relevant to hardware devices.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices intended for use in vitro for the examination of specimens, including blood, tissue, and urine, derived from the human body, solely or principally for the purpose of providing information concerning a physiological or pathological state, or concerning a congenital abnormality, or to determine the safety and compatibility with potential recipients, or to monitor therapeutic measures.
- Device Function: The description clearly states that this device is an electrosurgical instrument used in vivo (within the body) during endoscopic procedures to perform actions like ablation, incision, cauterization, and tissue removal directly on the gastrointestinal tract. It also injects substances into the submucosal layer.
- Lack of Specimen Examination: The device does not examine specimens outside of the body. Its function is to directly interact with and modify tissue within the patient.
Therefore, based on the provided information, the FUJIFILM Diathermic Slitter (FlushKnife) is a surgical instrument used in vivo, not an In Vitro Diagnostic device.

Intended Use / Indications for Use
These products are used in combination with an applicable endoscope to perform the endoscopic treatments for the target site in the gastrointestinal tract, such as ablation, incision, dissection, cauterization, coagulation and avulsion of tissue and arrest of bleeding, and to inject saline or submucosal injection agent for endoscopic surgery into the submucosal layer in the gastrointestinal tract, which is exposed after dissection, under the management of physicians in medical facilities. Never use this product for any other purpose.
