Indications for Use
The ForceTriad™ generator is a full-featured electrosurgical generator intended for open and laparoscopic surgical procedures where the surgeon requires electrosurgical cutting, coagulation, or vessel sealing (tissue fusion) in general, urologic, thoracic, plastic and reconstructive, arthroscopic, gynecologic and similar surgery. The ForceTriad™ generator is intended for use in the operating room, surgery center, or clinic. The generator has both monopolar and bipolar outputs that accommodate standard electrosurgical devices and Valleylab electrosurgical devices with surgeon power control. The ForceTriad™ generator also incorporates the functionality of the Valleylab LigaSure™ vessel sealing system, and accepts Valleylab LigaSure™ devices.
Device Story
Electrosurgical generator providing monopolar, bipolar, and vessel sealing outputs; used in OR, surgery centers, or clinics. Inputs include electrical impedance data from tissue; microcontroller-based system uses Instant Response™ technology to continuously monitor impedance and adjust output power to maintain desired tissue effect. Features include monopolar modes (Cut, Blend, Hemostasis with Division, Fulgurate, Spray) and bipolar modes (Low, Standard, Macro). Smart™ connector technology identifies connected Valleylab devices, enabling surgeon power control via slider switches on the device. Output affects clinical decision-making by providing controlled hemostasis and tissue division. Benefits include reduced thermal damage and consistent vessel sealing. Surgeon operates via touch screen or device-integrated controls. Patient return electrode (REM™) required for monopolar modes to prevent burns.
Clinical Evidence
Bench testing only. Performance testing was conducted to ensure the device functions as intended and meets design specifications, confirming substantial equivalence to predicate devices.
Technological Characteristics
Microcontroller-based, electrically isolated electrosurgical generator. Features closed-loop control and Instant Response™ technology for real-time impedance monitoring.

## 2. Name of Device
Trade or Proprietary Name: Valleylab ForceTriad™ Electrosurgical Generator
Common Name: Electrosurgical Generator
### Classification Name:
- Class II, 21 CFR 878.4400, Electrosurgical Cutting and Coagulation Device . and Accessories, Panel 79, General and Plastic Surgery
- Class II, 21 CFR 884.4120, Gynecologic Electrocautery and Accessories .
### 3. Predicate Devices
The ForceTriad™ Electrosurgical Generator is substantially equivalent in function and intended use to the following legally marketed devices: Valleylab Force FX ™ Electrosurgical Generator (K944602) and the Valleylab LigaSure™ Vessel Sealing System (K981916). The ForceTriad™ generator and the Force FX™ generator both have monopolar and bipolar electrosurgical outputs and are intended for all types of surgical procedures where electrosurgery is desired. Both have a selection of CUT and COAG monopolar outputs, and can be used with conventional electrosurgical devices. The ForceTriad™ generator has an additional monopolar output, Hemostasis with Division, that allows the surgeon to maintain controlled hemostasis while dividing tissue. The HWD output has power output and maximum voltage output in the same range as the other monopolar outputs. It is available when using the Valleylab G3000 electrosurgical device.
The ForceTriad™ generator and the LigaSure™ vessel sealing generator both have outputs for LigaSure™ vessel sealing devices. The output power and voltage of the generators are equivalent.
### 4. Device Description
The ForceTriad™ generator is a full-featured electrosurgical generator with monopolar, bipolar, and Valleylab LigaSure™ vessel sealing outputs. The generator
{1}------------------------------------------------

is an electrically isolated, microcontroller-based device, incorporating closed-loop control for all output modes implemented in the microcontroller firmware. The generator incorporates Instant Response™ technology to constantly measure the electrical impedance of the tissue and instantaneously adjust the generator output to maintain the desired power.
Available output modes include:
#### Monopolar
- Cut : clean, precise cut in tissue, with little or no hemostasis .
- Blend: blended waveform for slower cutting and additional hemostasis
- Hemostasis with division (HWD): optimized division of tissue with controlled . hemostasis and minimal thermal damage to adjacent tissue
- Fulgurate: tissue coagulation by sparking .
- Spray: fulguration with shallower penetration over larger tissue areas t Bipolar
- Low: precise, controlled desiccation of tissue .
- Standard: general bipolar desiccation with consistent tissue effect .
- Macro: rapid coagulation and bipolar cutting in a wide range of tissues . LigaSure™ vessel sealing
- Seals vessels (arteries, veins, lymph) 7mm and less, and tissue bundles. .
The monopolar Cut, Blend, Fulgurate, and Spray output modes are designed for use with conventional handswitching or footswitching electrosurgical devices. The three bipolar output modes are designed for use with conventional handswitching or footswitching electrosurgical bipolar forceps. When using conventional electrosurgical devices, the user selects the mode and desired power using a touch screen display on the generator.
All monopolar output modes, including HWD, are also designed for use with Valleylab electrosurgical devices with surgeon power control. The surgeon power control devices utilize Valleylab Smart™ connector technology that allgows the generator to identify the type of device in use. After recognizing the device type, the generator establishes five power zones for each output mode. The generator defaults to power zone 3, but the surgeon may select an alternate power zone using the touch screen. From the sterile field, the surgeon then uses the slider switch on the device to select the desired power setting within the selected power zome. The surgeon activates the desired output mode (CUT, HWD, COAG) using the buttons on the device. The surgeon also has the option of using the touch screen controls to select power levels outside the pre-established power zones to accommodate unusual surgical situations.
Monopolar electrosurgery requires the use of a patient return electrode ("return pad" or "grounding pad") with Valleylab REM™ return electrode monitoring. The REM™ system continuously verifies contact between the patient and pad togs one headsite burns. (Valleylab REM™ electrodes were initially cleared for marketion on K822572, and have been used on all Valleylab electrosurgical generators since that

time.) Bipolar devices and LigaSure™ vessel sealing devices do not require patient return electrodes.
The ForceTriad™ vessel sealing mode is designed for use with LigaSure™ vessel sealing devices. The LigaSure™ devices utilize Smart™ connector technology to allow the generator to recognize the device in use and set the generator output accordingly. (Refer to K981916, LigaSure™ Vessel Sealing System.)
#### 5. Intended Use
The ForceTriad™ generator is a full-featured electrosurgical generator intended for open and laparoscopic surgical procedures where the surgeon requires electrosurgical cutting, coagulation, or vessel sealing (tissue fusion) in general, urologic, thoracic, plastic and reconstructive, arthroscopic, gynecologic and similar surgery. The ForceTriad™ generator is intended for use in the operating room, surgery center, or clinic. The generator has both monopolar and bipolar outputs that accommodate standard electrosurgical devices and Valleylab electrosurgical devices with surgeon power control. The ForceTriad™ generator also incorporates the functionality of the Valleylab LigaSure™ vessel sealing system, and accepts Valleylab LigaSure™ devices.
Valleylab makes the following recommendations with regard to the use of the ForceTriad™ electrosurgical generator.
- Use electrosurgery with caution in the presence of internal or external . pacemakers. Interference produced by the use of electrosurgical devices can cause a pacemaker to enter an asynchronous mode or can block the pacemaker effect entirely. Consult the pacemaker manufacturer or hospital Cardiology Department for further information when use of electrosurgical or tissue fusion appliances is planned in patients with cardiac pacemakers.
- If the patient has an implantable cardioverter defibrillator (ICD), contact the ICD . manufacturer for instructions before performing an electrosurgical or tissue fusion procedure. Electrosurgery or tissue fusion may cause multiple activations of ICDs.
Valleylab recommends against the use of laparoscopic surgery on preqnant patients.
LigaSure™ tissue fusion has not been shown to be effective for tubal sterilization or tubal coagulation for sterilization procedures. Do not use this function for these procedures.
