# Device Description:

The EPi-Sense Guided Coagulation System with VisiTrax - generation 4 product) consists of a sterile, single-use, disposable coagulation electrode device (1cm, 2cm, & 3cm sizes provided) intended to be used to coagulate cardiac tissue. The flexible, cooled electrode device, with a suction stabilizer feature, transmits radiofrequency (RF) energy from an Electrosurgical Generator (non-sterile, re-useable) connected through an Instrument Cable (sterile). An optional temporary sensing electrode feature may be used with . an off-the-shelf electrogram recording system with the use of an additional instrument cable (non-sterile).

## Indications for Use:

Indications for Use: The EPi-Sense™ Guided Coaqulation System with VisiTrax® is intended for the coagulation of cardiac tissue using Radiofrequency (RF) energy using thoracoscopic, endoscopic, and laparoscopic surgical techniques.

The EPi-Sense™ Guided Coagulation System with VisiTrax® may be used for temporary cardiac signal sensing and recording during surgery when connected to a temporary external recording device.

# Comparison to Predicate Device and Summary of Technological Characteristics:

The nContact EPi-Sense System has the identical intended use and technological characteristics as the predicate nContact Numeris System for the coagulation function. The sensing function is considered equivalent to the stated predicate #2 for temporary cardiac signal sensing and recording when connected to a temporary external recording device.

The nContact Coagulation System combines design features of marketed predicate devices. The design features of the subject device are the same as or fall within ranges specified by the predicate devices. The dimensional parameters, materials, generator specifications, and design specifications are covered within the ranges offered by predicate devices. Shared features include:

- All devices (subject and predicate) rely on transmitting radiofrequency . energy through electrodes to achieve the intended coagulation use.
- Electrode design is identical to predicate #1. ●
- Perfusion feature is identical to predicate #1. .
- Suction feature is identical to predicate #1. .
- RF Generator energy levels, software revision and hardware are . identical to predicate #1.
- . Temporary cardiac signal sensing feature is similar the function in predicate #2.

# Summary of Nonclinical Testing:

Performance bench tests were executed to ensure that the EPi-Sense Guided Coagulation System with VisiTrax (Generation 4 product) performed as intended and met design specifications.

The subject device incorporates design features and specifications equivalent to those specified by the predicate devices. In vitro and in vivo testing was conducted to verify that no safety or effectiveness issues arise when using the subject device to coagulate cardiac tissue or during use for the temporary cardiac signal sensing and recording function.

The following tests were successfully completed to evaluate equivalence.

- 1. Biocompatibility testing per ISO 10993 for device and accessory materials.
- 2. Sterilization validation per ISO 11137-2, Sterilization of Health Care Products - Radiation - Method VD Max.
- 3. Reliability testing such as shipping and accelerated aging of packaged units.
- 4. Tensile testing of critical bonds and joints.
- 5. Flexion fatique testing.
- 6. Electrical integrity testing for the subject device and accessories to pertinent sections of IEC 60601-1-2.
- 7. In-vivo pre-clinical testing to demonstrate equivalent performance for coagulating cardiac tissue and temporary cardiac signal sensing.
- 8. In-vitro bench testing to demonstrate tissue coagulation feature equivalence.

## Substantial Equivalence Conclusion:

nContact concludes that the material and design modifications for the EPi-Sense Guided Coagulation System with VisiTrax may be considered substantially equivalent or identical to the legally marketed predicate devices based on the results of design verification and validation. The indications for use, principle of operation, technology, performance specifications (as reverified through design controls), labeling and sterilization parameters have no substantial changes or modifications that significantly affect the safety or efficacy of the devices. The Epi-Sense Guided Coagulation System with VisiTrax is substantially equivalent to the stated predicate devices.
