• Attributes: Therapeutic

Intended Use

The Viveve 2.0 System is indicated for use in general surgical procedures for electrocoagulation and hemostasis.

Device Story

The Viveve 2.0 System is an electrosurgical device using monopolar radiofrequency (RF) energy to heat tissue beneath the surface while simultaneously delivering cryogen to the treatment tip to cool surface tissue (reverse thermal gradient). Components include an RF generator with integrated cooling module, handpiece, footswitch, and sterile disposable treatment tips (5cm or 8cm). The system includes a Contact Quality Monitoring (CQM) feature that monitors return pad contact via a contact map on the user interface to ensure safe energy dissipation. Used in clinical settings for electrocoagulation and hemostasis. The healthcare provider operates the system, monitoring the interface for contact quality and system status. The device benefits patients by providing controlled thermal coagulation during surgical procedures.

Clinical Evidence

Bench testing only. No clinical data presented. Verification testing included hardware/software verification of the CQM circuit (response time <20ms, resistance measurement accuracy), electrical safety (AAMI ES60601-1, CSA C22.2#60601-1), and EMC (IEC 60601-1-2). Validation testing using phantom tissue (pork belly) confirmed the CQM interface correctly detects return pad contact and triggers system faults (E63 error) upon loss of contact.

Technological Characteristics

Monopolar electrosurgical system; RF energy (6.78 MHz ±15%); cryogen cooling; 50W max power; impedance range 20–185 Ω. Includes Contact Quality Monitoring (CQM) circuit. Sterile disposable treatment tips (ETO sterilized). Connectivity includes return pad and cable. Software-controlled UI with contact map. Complies with AAMI ES60601-1, IEC 60601-1-2, IEC 60601-2-2, and IEC 60601-1-6.

Indications for Use

Indicated for use in general surgical procedures for electrocoagulation and hemostasis. Patient population not specified.

### 5.4 PREDICATE DEVICE

Viveve 2.0 System (K190422)

### 5.5 DEVICE DESCRIPTION

The Viveve 2.0 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.

The Viveve® 2.0 System consists of four (4) primary components:

- . An RF Generator to provide the heating energy. The Generator incorporates the Cooling Module to supply coolant which provides the cooling energy.
- . A hand piece that couples the cooling and heating energy to the tissue through the treatment tip.
- A footswitch that allows the user to turn the RF Energy on or off.
- . 5cm or 8cm Sterile Disposable Treatment Tips.

## 5.7 COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE

The technological characteristics of the subject device Viveve 2.0 System are substantially equivalent to the predicate device, Viveve 2.0 System (K190422). The Viveve 2.0 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. The subject device differs from the predicate device in the addition of Contact Quality Monitoring (CQM). The device software monitors the return pad to determine if it is adequately secured to the patient's body in order to dissipate any residual radiofrequency energy. The display module software differs from that of the predicate device only in the addition of a Contact Map which indicates the amount of contact between the return pad and the patient's skin. In all other regards the display module software is identical. The design specifications of the subject device are identical to the predicate device specifications with the sole exception of the addition of CQM and the modification to the user interface.

This submission application confirms the continued conformance to applicable technical design specifications and performance requirements, including requirements associated with industry safety and performance standards.

## 5.8 BASIS FOR DETERMINATION OF SUBSTANTIAL EQUIVALENCE

The Viveve 2.0 System is substantially equivalent to the predicate device listed in K190422. The principle of operation between the predicate device and the subject device remain the same as do all output parameters to tissue.

Specifications of the Viveve 2.0 System are discussed in further detailed in Section 09: Substantial Equivalence Discussion of this Premarket Notification. A comparison of the technical characteristics of Viveve 2.0 System are compared to those of the predicate device, Viveve 2.0 System, in Table 5-1 below.

All the above Intertek test reports are on file at Viveve and are available in full upon request.

- 3. Viveve performed a master Viveve 2.0 System Validation to ensure the CQM software performs appropriately. The following parameters were tested:
- Ensure the CONTACT MAP graphic within the Graphic User Interface is not ● illuminated when the Return Pad is not connected to the phantom tissue (pork belly) and is illuminated green when the Return Pad is connected to the phantom tissue.
- . When the Return Pad is not adequately connected to the phantom tissue, the RF Generator will fault and result in an E63 - Check Tip Contact error. Acknowledge the error by selecting OK. Place the Return Pad securely on the phantom tissue so that the CONTACT MAP is illuminated and ensure a pulse is delivered.

The Verifications, EMC and IEC Testing, and Validation ensure that the CQM addition to the Viveve 2.0 System are performing to the correct specifications for safety and efficacy of the device.

# 5.10 CONCLUSION

The following results were achieved referencing the tests performed in 1-3 above:

- 1. The RF Generator performed as expected when the contact resistance was measured at the appropriate values. The CQM reading was as expected between 50 Ω± 10 Ω with the RF Activated. The voltage on channel 1 of the oscilloscope transitioned 63% of the way from low too high in <= 20ms. The RF Generator did fault when the CQM circuit was not complete resulting in radiofrequency interruption to the patient. All of the above parameters were met and were recorded as PASS results.
- 2. Intertek performed the above tests according to the applicable standards. All of the above parameters were met and were recorded as PASS results.

{8}------------------------------------------------

Image /page/8/Picture/1 description: The image shows the word "viveve" in a sans-serif font. The color of the text is a light green. There is a small circle to the right of the last "e" in the word.

- 3. During the execution of the protocol, all tested functions performed as expected. Test results indicated that the CQM updates to the Viveve 2.0 System have met the impacted customer requirements, identified within ENG-017 Impact Analysis for CQM Updates.
The Viveve 2.0 System successfully passed all functional testing performed in the protocol.

Noting all testing performed above, considering the risk and safety of the device, the Viveve 2.0 System performed as expected after the addition of the CQM Software. The changes to the Viveve 2.0 System Software do not raise questions of safety or efficacy of the overall system; therefore, the Viveve 2.0 System is substantially equivalent to the predicate device.
