Dear Jae-Hun Lee:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's

{1}------------------------------------------------

requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part

801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).

In accordance to ISO10993-1, the following biocompatibility tests were performed : Cytotoxicity, Maximization, Intractutaneous Reactivity, Acute Systemic Toxicity, Pvrogen test.

#### 3) Performance Testing

#### (1) Demension test

When measured by vernier calipers, the tolerance of the nominal size should be ±10 % of the stndard. For the dimensional test, all dimensions of the core-snare non-rotation type product were measured. As a result of the measurement, it was confirmed that all dimensional values do not exceed the tolerance of ±10%. Therefore, the CORE-SNARE meets the performance required by demension test.

#### (2) Tensile strength test

#### (1) Electrode Cable

The tensile strength test method for Electrode Cable was performed in accordance with ANSI/AAMI HF 18 (2001) 4.2.5.5, and according to method, Electrode cables and connecting parts shall not be damaged from 40 N pulling and 0.64 J impact. The proposed device was tested, and there was no damaged from 40 N pulling and 0.64 J impact.

Therefore, the CORE-SNARE meets the performance required by tensile strength of electrode cable.

#### (2) Inner rope-cutting wire

The tensile strength (inner rope-cutting wire) was tested as follows.

The cutting knife is cut out from the sheath by manipulating the handle. The inner rope and the cutting wire are cut at a position of about 15cm from the end to make a specimen, and the specimen is pulled at a rate of 1.0 in/min.

Under the conditions of the above method, the strength between the inner rope and the cutting wire should be not less than 15 lbs.

The proposed device was tested, and It was confirmed the strength is more than 15 lbs.

Therefore, the CORE-SNARE meets the performance required by tensile strength of

inner rope-cutting wire.

#### 3 Catheter sheath-handle

The tensile strength (catheter sheath-handle) was tested as follows. After manipulating the handle, pull out the cutting knife out of the sheath, cut the sheath and cable at 2 inches of the distal end of the strain relief to make a specimen, and pulled at a rate of 1.0 in/min. Under the conditions of the above method, the strength between the catheter sheath and the handle should be not less than 2 lbs. The proposed device was tested, and there was more than 2 bs. Therefore, the CORE-SNARE meets the performance required by tensile strength of catheter sheath-handle.

- (3) Cable Withstand voltage
The main frequency withstand voltage meets the test criteria that the rate accessory voltage specified by the manufacturer of the high frequency surgical accessory must withstand a peak voltage of 1000V, large DC or Mains frequency for 5 minutes.

And the high-frequency withstand voltage must withstand for 30 seconds at high frequency voltage of 120% of the rated accessory voltage presented by the manufacturer. Maximum voltage of accessory is 920 Vp.

For the test, refer to the test method with the following IEC 60601-2-2:2011. The proposed device was tested according to the above criteria and passed. Therefore, the CORE-SNARE meets the performance required by Cable Withstand voltage.

- (4) High Frequency leakage current test
High frequency leakage current testing has been performed in accordance with ANSI / AAMI HF 18(2001) 4.2.5.2.

The monopolar high-frequency leakage current of the electrode cable shall be not more than 3.6 dfL mA and, the connection cord shall not have worked loose nor shall it show any damage.

For multiconductor cables there shall be no short circuits betwwen individual conductors.

The proposed device was tested according to the above criteria and passed.

Below the word "INCORE" is a thin line, and below that is some smaller text that is difficult to read. The circular design on the left appears to be three overlapping circles with a dark blue fill in the intersection.

Therefore, the CORE-SNARE meets the performance required by High frequency leakage current test

(5) Conductive Inspection (Continuity test)

This test is performed using electrical conduction circuit system, and tips for connection with electrode tip must be electrically connected to each other. The proposed device was tested according to the above criteria and passed. Therefore, the CORE-SNARE meets the performance required by Conductive inspection.

#### 4) Physical/Chemical

Extraction Test is tested accordance with In-house hold.

Test items are Appearance, pH, KMnO4 Consumption, Evaporating residue, Ultraviolet absorption, Heavy metal are acceptable level.

#### 5) Shelf Life Test

The CORE-SNARE has a maximum shelf life of 3 years from the date of sterilization. In compliance with the standard of ASTM F1980 ; Standard Guide For Accelerated Aging of Sterile Barrier System for Medical Device, accelerated aging studies for start and three(3) years were performed to determine product integrity over its lifespan, with acceptable results. A real-time aging study is currently in process to verify the result found in the accelerated aging studies.

## VIII. Conclusion

The conclusion drawn from the technological characteristics is that the CORE-SNARE has been found to have a safety and efficacy profile that is substantially equivalent to the predicate device ClearGrasp Snare which is marketed for the same intended use.
