## Intended Use

The VivaWave™ Microwave Ablation System is intended for coagulation of soft tissue. The Coaxial Introducer is intended to aid insertion of the microwave energy applicator component of the system. The system is not intended for use in cardiac procedures.

#### Predicate Devices

VivaWave™ Microwave Ablation System

K011676

## Device Description

The VivaWave™ Microwave Ablation System consists of a microwave power generator and a disposable probe that is the microwave energy applicator. The disposable probe is inserted into soft tissue to coagulate a volume of tissue surrounding the active area of the probe. The Coaxial Introducer may be used to aid insertion of the microwave energy applicator.

#### Materials

All patient contact materials used in the manufacture of the Coaxial Introducer are suitable for this use and have been used in numerous previously cleared products.

#### Summary of Substantial Equivalence

The VivaWave Microwave Ablation System with the addition of the Coaxial Introducer is equivalent to the predicate products. The indications for use, basic overall function, methods of manufacturing, and materials used are substantially equivalent. Vivant Medical believes the Coaxial Introducer is substantially equivalent to existing legally marketed devices.
