Indications for Use
The Viveve System is indicated for use in general surgical procedures for electrocoagulation and hemostasis.
Device Story
Viveve System is an electrosurgical device using monopolar radiofrequency (RF) energy to heat tissue for coagulation and hemostasis. System components include an RF generator with integrated cooling module, handpiece, footswitch, and sterile disposable treatment tips (5 cm and 8 cm). During operation, RF energy creates an electric field beneath the treatment tip to heat internal tissue, while cryogen is delivered to the tip interior to cool surface tissue (reverse thermal gradient). Used in clinical settings by healthcare providers. Output is controlled via footswitch; healthcare providers monitor the procedure to achieve desired coagulation. Benefits include controlled thermal tissue effects while protecting surface layers.
Clinical Evidence
No clinical data was provided. Substantial equivalence was demonstrated through bench testing, including design verification, biocompatibility, electrical safety, and electromagnetic compatibility testing.
Technological Characteristics
Monopolar RF electrosurgical system; 6 MHz continuous sinusoidal waveform; 240W max power; 25-120 Ω impedance range. Features cryogen-based surface cooling.

#### 7.4 PREDICATE DEVICE
- . Viveve System (K162547)
### DEVICE DESCRIPTION 7.5
The Viveve System utilizes monopolar radiofrequency (RF) energy to selectively heat a given volume of tissue beneath the surface, while cryogen is delivered to the inside of the treatment tip to cool the surface tissue. The generator delivers energy to the treatment tip to create an electric field under the treatment tip (electrode). The mechanism of action is the application of RF energy to the tissue causing coagulation and/or hemostasis.
{4}------------------------------------------------
The Viveve System consists of four (4) primary components:
- . An RF Generator to provide the heating energy. The Generator incorporates the Cooling Module to supply the coolant which provides the cooling energy.
- A hand piece that couples the cooling and heating energy to the tissue through the treatment tip (below).
- A footswitch that allows the user to turn the RF Energy on or off. ●
- 5 cm and 8cm Sterile Disposable Treatment Tips. ●
Accessories include:
- Coupling Fluid ●
- Cryogen ●
- Return Cable
- . Return Pad
- Power Cord ●
#### 7.6 INDICATION FOR USE
The Viveve System is indicated for use in general surgical procedures for electrocoagulation and hemostasis.
### 7.7 TECHNICAL CHARACTERISTICS
The Viveve System is an electrosurgical device that delivers radiofrequency (RF) energy to selectively heat a given area of tissue., while cryogen is delivered to the inside of the treatment tip to cool the surface tissue at the end of energy deposition. The application of RF energy causes the tissue to coagulate and/or become hemostatic.
#### 7.8 SUBSTANTIAL EQUIVALANCE
The Viveve System is substantially equivalent to the predicate device listed. The principle of operation between the predicate device and the subject device remain the same, however the subject device is modified with a design change to add an8 cm Treatment Tip. These changes have been tested and verified to have no effect on system functionality, safety, or effectivity. The function of the subject device, the materials and indication for use have not changed, therefore, the subject device is substantially equivalent to the predicate device listed.

### PERFORMANCE DATA 7.9
The modifications made to the Viveve System were found to not affect safety or performance through design verification bench testing, which confirmed the continued conformance to applicable technical design specifications and performance requirements, including requirements associated with industry safety and performance standards, as follows:
- Safety and essential performance testing in accordance with IEC 60601-. 1:2005 (2006/07-3rd edition) and IEC 60601-2-2:2009
{6}------------------------------------------------
- Electromagnetic compatibility in accordance with IEC 60601-1-2:2007 ●
- Design verification testing to ensure the proposed modifications perform ● within design parameters under the proper environmental conditions.
- . Software validation was conducted to ensure the proposed modification perform with the design parameters.
#### 7.9.1 Non-Clinical Performance Data
Design verification and biocompatibility testing was performed to ensure the subject device Viveve System functions according to the intended use. The results met the acceptance criteria. Risk analysis was also completed in accordance with criteria based on ISO 14972:2007. Electromagnetic compatibility and electrical safety testing was completed in compliance with IEC 60601-1 and IEC 60601-1-2. Biocompatibility testing was conducted for the Treatment Tip and Coupling Fluid according to ISO 10993-1:2009. Other components of the Viveve System do not have direct contact with patient tissue, therefore biocompatibility testing was not required. Sterilization for the subject device remains the same as the predicate device sterilization method and parameters. Packaging validation testing was also completed against the subject device along with the shelf life testing.
#### 7.9.2 Clinical Performance Data
This premarket submission did not rely on the assessment of clinical performance data to demonstrate substantial equivalence as the only change was to the length of the Treatment Tip shell, all internal components are identical.
#### 7.10 CONCLUSION
The indications for use and the technical characteristics of the Viveve System has not changed from the predicate device. The results of performance testing demonstrate that the modifications to the Viveve System do not affect the safety, efficacy, or performance of the System, therefore, the subject device is substantially equivalent to the predicate device.
