#### Device Description:

The EPi-Sense Guided Coagulation System with VisiTrax 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). A 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). An accessory Cannula may be used to facilitate coagulation device access and visibility of the heart. The Cannula accessory changes are the subject of this submission.

#### Indications for Use:

Indications for Use: The EPi-Sense® Guided Coagulation 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.

#### Description of Change for this Submission:

The following changes are being made to the Cannula Accessory for the EPi-Sense Guided Coaqulation System with VisiTrax.

- Manufacturing process change for the cannula tip from an extrusion ● process to a molded process
- Material/part vendor changes ●
- Vacuum tubing wall thickness increase
- Addition of blue lumen marker ●
- Sterile barrier pouch sealing operation change of location .
- Addition of two Cannula models

#### Comparison to Predicate Device and Summary of Technological Characteristics:

The nContact EPi-Sense System described in this submission is identical to the predicate nContact EPi-Sense System described in K120857 and has the identical intended use and technological characteristics.

- · Coagulation Device functions, such as perfusion, suction, the RF electrode, and sensing electrodes are identical, with use of the same RF Generator and connecting cables.

{5}------------------------------------------------

- The Cannula accessory used with the EPi-Sense device has minor ● changes as described above with design features that are the same or slightly modified from the previous Cannula design.
### Summary of Nonclinical Testing for Accessory Cannula:

Performance bench tests were executed to ensure that the Cannula accessory performed as intended and met design specifications in conjunction with the EPi-Sense Guided Coagulation System with VisiTrax.

The EPi-Sense device incorporates design features and specifications identical to those specified by the predicate device, there were no changes made to the coagulation device. The Cannula accessory with minor changes has completed testing to verify that no safety or effectiveness issues arise when using the coagulation device in conjunction with the Cannula.

The following tests were successfully completed to evaluate equivalence.

- 1. Biocompatibility testing per ISO 10993 for cannula accessory materials.
- 2. Sterilization validation per ISO 11137-2, Sterilization of Health Care Products - Radiation - Method VD Max for cannula accessory.
- 3. Reliability testing such as shipping and accelerated aging of packaged units.
- 4. Tensile testing of critical bonds and joints.
- 5. Flexion fatigue testing.
- 6. Electrical integrity testing for the cannula accessory used with the coagulation device to pertinent sections of IEC 60601-1-2.

#### Substantial Equivalence Conclusion:

nContact concludes that the modifications for the Cannula Accessory used with 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 re-verified through design controls), and 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 with Accessory Cannula is substantially equivalent to the stated predicate device.
