Indications for Use

The Surginetics AdvantageBlade is intended as an alternative to uncoated stainless steel as well as coated electrodes for use in conventional monopolar electrosurgical accessories. The AdvantageBlade is intended for use in situations where monopolar electrosurgery is used.

Device Story

AdvantageBlade is a coated electrode accessory for monopolar electrosurgical pencils. Device functions by delivering electrical energy to tissue to perform cutting and coagulation. Coating facilitates cleaning of tissue residues (eschar) and reduces smoke plume production during surgery. Used in OR settings by surgeons; compatible with standard electrosurgical pencils from other manufacturers. Benefits include reduced smoke, lower wattage requirements, less tissue damage, and improved mechanical integrity of insulation compared to predicate devices. Healthcare providers use the device to achieve effective tissue cutting with less drag and improved visibility due to reduced smoke.

Clinical Evidence

Bench testing only. Titrated Power Test on fresh beef liver compared AdvantageBlade to predicate devices (n=3 per group). Metrics included power (Watts), delay/drag score, smoke score, eschar score, and tissue damage score. AdvantageBlade showed superior performance across all metrics. Insulation Penetration Test measured time to failure and weight required to penetrate insulation; AdvantageBlade demonstrated significantly higher mechanical integrity (no failure) compared to predicate coated blades (immediate failure).

Technological Characteristics

Coated electrosurgical blade electrode. Designed for use with standard monopolar electrosurgical pencils. Features proprietary coating for reduced eschar accumulation and improved insulation mechanical integrity. Energy source: external electrosurgical generator. Dimensions/form factor: blade-style electrode. Sterilization: not specified.

Indications for Use

Indicated for use in surgical procedures (general, neurosurgical, laparoscopic, orthopedic, gynecologic, etc.) where monopolar electrosurgical cutting and coagulation are normally used. Intended for patients requiring monopolar electrosurgical intervention.

Regulatory Classification

Identification

### Intended Use

The Surginetics AdvantageBlade is intended as an alternative to uncoated stainless steel as well as coated electrodes for use in conventional monopolar electrosurgical accessories. The AdvantageBlade is intended for use in situations where monopolar electrosurgery is used.

### Product Description

The Surginetics AdvantageBlade is a coated blade intended for use as a monopolar electrosurgical accessory. The blade reduces the smoke emitted into the surgical area, uses lower wattages with less tissue damage and the coating provides a surface that facilitates ease of cleaning of tissue residues that may accumulate during use. The coating provides for ease of eschar cleaning.

The blades are intended for use with monopolar electrosurgical accessories and will be packaged separately. The coated blades will also fit in currently marketed electrosurgical pencils offered by other manufacturers.

# Statement of Substantial Equivalence

Surginetics AdvantageBlade is substantially equivalent in function and intended use to the following legally marketed devices:

- Valleylab Uncoated E1551X 1.
- Valleylab Coated E1450X EDGE 2.

For additional information see the information in Tables 1, A3-1, and A3-2.

### Safety and Performance

#### 1. Biocompatibility Testing

The biological safety of the Surginetics AdvantageBlade has been assured through the selection of materials which demonstrate appropriate levels of biocompatibility. The components of the blades have incidental short term contact with patient tissues at the surgical site.

#### Performance Testing 2.

Performance testing was performed on prototype Surginetics AdvantageBlade electrodes. The configuration is representative of the range of electrodes that will be available in coated form.

Testing that adjusted the power from an electrosurgical generator (a Valleylab Force FX) until a particular blade cut effectively was used to obtain most of the performance data. This test, which is called a Titrated Power Test because it adjusts the power until effective cutting occurs, was used to determine the power level at which effective cutting occurred, the amount of delay and drag during cutting, the amount of smoke produced, the amount of eschar accumulated, and the amount of tissue damage. The tissue sample used was fresh beef liver (about six hours old). Beef liver is used because its consistency and size enables high quality comparisons.

Another test, the Insulation Penetration Test, carefully placed a sharp penetrator on the insulated surface of a coated blade and then periodically increased the load on the penetrator and measured the time until the penetrator pushed through the insulating coating and contacted the underlying metal blade.

- Electrode low power cutting �
The Surginetics AdvantageBlade starts cutting effectively at lower power than the predicate uncoated and coated blades. Refer to Table A3-1 for the test data.

- Initial delay/drag .
The Surginetics AdvantageBlade produced less drag at startup than the predicate uncoated and coated blades. Refer to Table A3-1 for the test data.

- Electrode smoke plume production ●
The Surginetics AdvantageBlade produced less smoke than the predicate uncoated and coated blades. Refer to Table A3-1 for the test data.

- Electrode eschar accumulation ●
The Surginetics AdvantageBlade produced less eschar than the predicate uncoated and coated blades. Refer to Table A3-1 for the test data.

- Tissue damage ●
The Surginetics AdvantageBlade produced less tissue damage than the predicate uncoated and coated blades. Refer to Table A3-1 for the test data.

- Coating penetration ●
The Surginetics AdvantageBlade demonstrated better mechanical integrity when subjected to mechanical penetration forces than the predicate coated blades. This characteristic is not germane for uncoated blades. Refer to Table A3-2 for the test data.

Some of the differences in the test results are large enough that it may appear that errors exist. That is not the case. Noticeable differences exist in the results. For example, the Delay/Drag score for Valleylab E1450X EDGE Blade #1 is 200 because that blade had more drag during both of the cuts made with it. Similarly, both Valleylab blades

produced clouds of smoke and caused tissue damage (dark brown cooked tissue appearance) and the AdvantageBlade devices did not produce any smoke and left the tissue looking as if it had been cut with a sharp steel scalpel. Similar differences were noted in the Eschar scores.

The Delay/Drag scores for the AdvantageBlade electrodes are low because the blades gave the distinct impression of gliding through the tissue. The other blades produced delays at the start of cutting or dragged, or both.

The insulation penetration tests were carried out with meticulous care when the penetrator (an 18 gauge x 1.5 inch Monoject needle) was placed on the surface of the insulation of each blade. For example, the test fixture was configured so that it was never moved after the needle was positioned on the blade. This technique was used to prevent vibrating or otherwise causing motions that would induce the tip of the needle to work its way into the insulation and toward the metal portion of the blade. In spite of this great care, all of the Valleylab E1450X EDGE blades failed as soon as the tests started. The test results show the time being 0.1 seconds. That is the shortest time interval that the apparatus can measure. The weight of the needle and container above it that accumulates weight during the test run is 7.3 grams. Therefore, a time to failure of 0.1 seconds and a weight of 7.3 grams means that the needle's tip with no added weight penetrated the insulation within the few seconds it took to place the penetrator on the blade's surface and start the timer.
