# Intended Use / Indications for Use

Diathermic Slitter (FlushKnife) DK2618J and DK2623J are intended to be used with specified endoscopes to cut tissue using high-frequency current within the digestive tract. The devices are indicated for ablation, incision, dissection, avulsion, coagulation and hemostasis of tissue within the digestive tract.

Diathermic Slitter (ClutchCutter) DP2618DT is intended to be used with specified endoscopes to cut tissue using high-frequency current within the digestive tract. The device is indicated for ablation, incision, dissection, avulsion, coagulation and hemostasis of tissue within the digestive tract.

## Device Description

The Fujifilm Diathermic Slitter (FlushKnife) and Diathermic Slitter) (the "devices") are electrosurgical instruments that remove tissue and control bleeding by use of high-frequency ("HF") electrical current. The devices are provided sterile for single-use only. The devices are provided in various models (described below), but each is comprised of the following major components:

The FlushKnife and ClutchCutter consist of the following major components:

- · Slitter Electrode at distal tip of the device that performs ablation, incision, dissection, avulsion, cauterization, coagulation, and hemostasis of tissue via delivery of HF electrical current.
- Operation wire Inner wire of the device that connects the handle and slider control to the slitter, facilitates manual control of slitter position, and delivers the HF electrical current to the slitter.
- · Tube Flexible resin tube that is inserted into body cavities and insulates operation wire carrying the HF electrical current.
- Slider Portion of handle that extends and retracts the slitter portion from the distal end of the tube (FlushKnife) or opens and closes slitter jaws (ClutchCutter) by means of the operation wire.
- · Handle Proximal end of the device that provides for user control.
- · Active Cord ("A-Cord") Connector Used to connect the device to the electrosurgical power supply unit via an A-cord.

The devices are comprised of a proximal handle with slider that is connected to a flexible resin tube. The flexible resin tube covers and insulates the operation wire and slitter (when retracted). The operation wire controls the mechanical function of and delivers HF electrical current to the slitter. The proximal end of the operation wire is connected to the slider, which allows the operator to manually control the extension of the slitter (for the FlushKnife) or open and close (ClutchCutter) of the slitter Jaws. The distal end of the operation wire connects to the slitter, which is located at the distal tip of the device.

The devices connect to a HF electrosurgical power supply unit by an active cord ("A-Cord") connector. HF electrical current generated by HF electrosurgical power supply unit flows to the slitter from the HF electrosurgical power supply unit via the A-cord connector, and the operation wire.

{5}------------------------------------------------

The distal tip of the device is inserted through the forceps channel of the specified endoscope. Once inserted, the operator can extend the slitter from the tip of the endoscope (FlushKnife) or opens and closes slitter jaws (ClutchCutter) using the slitter is extended to the target site of a patient. Cleavage, resection, incision, ablation, hemostasis, coagulation, or excision of tissue is achieved by delivering HF current to the target tissue through the slitter.

# Substantial Equivalence

The Fujifilm Diathermic Slitter (FlushKnife) and Diathermic Slitter (ClutchCutter) are as safe and effective as the Single Use Electrosurgical Knife (K092309) and the Electrosurgical Hemostatic Forceps Series (K062517). The FlushKnife and ClutchCutter have the same intended uses and similar indications, technological characteristics, and principles of operation as their predicate devices. The minor technological differences between the FlushKnife and their predicate devices raise no new issues of safety or new concerns of effectiveness. Performance data demonstrate that the FlushKnife and ClutchCutter are as safe and effective as the Single Use Electrosurgical Knife and the Electrosurqical Hemostatic Forceps Series. Thus, the FlushKnife and ClutchCutter have substantially equivalent performance to their predicate devices.

# Conclusions

The subject devices are substantially equivalent to the predicates based on intended use/indications for use and technological characteristics. The minor technological differences between the FlushKnife and ClutchCutter and their predicate devices raise no new questions of safety or new concerns of effectiveness.
