## De vice De scription
The Active Needle Endoscopic Treatment (ANET) Applicator (Model # ANET-00) is a disposable bipolar electrosurgical applicator intended for the coagulation and necrosis of soft tissue. Each Applicator consists of a needle (proximal electrode) with a coil (distal electrode). The needle and coil serve as the bipolar electrodes, so there is no need for an external ground pad.
The ANET Applicator is compatible with the cleared Olympus ESG-100 Electrosurgical Generator (K072307) and endoscopes with a working inner diameter of 2.2mm or greater, such as those cleared in K093395 and K100584. Other radiofrequency generators will be added as compatibility is established.
To perform ablation, the flexible catheter portion is first inserted into a compatible ultrasound endoscope working channel, then pushed forward until fully inserted. The handle is then affixed to the channel port of the endoscope via a mechanism locking onto the single use adapter biopsy

valve. The handle facilitates advancement of the needle/proximal electrode during puncture of the targeted ablation site. Once the proximal electrode is positioned, a separate handle control facilitates advancement of the distal electrode. Saline and power connections at the handle of the device deliver fluid (1-3cc/min) and energy respectively to the distal portion of the device. The needle size of the device is 19 gauge (19G). During operation, radiofrequency (RF) current is passed between the distal electrode and the proximal electrode to thermally coagulate the tissue.
The ANET device is provided sterile and is intended for single patient use. The device should only be used within a healthcare setting by physicians knowledgeable and experienced in RF ablation.
#### Device Materials (Patient Contacting)
The ANET Applicator is manufactured with materials commonly used in medical device applications. The patient contacting materials are included in Table 5-1 below:
| Patient Contacting Materials |
|------------------------------------------------|
| Acrylonitrile Butadiene Styrene (ABS) |
| 304 Stainless Steel,<br>17-7PH Stainless Steel |

#### Proposed Indication for Use
The Spiration ANET Electrosurgical Applicator is indicated for coagulation and ablation of soft tissue when used in conjunction with a compatible radiofrequency generator.
#### Comparison to Predicate
Spiration has chosen the EMcision Habib EUS RFA 6700 (K150029 & K161305) as the predicate for comparison to the proposed ANET Applicator. The predicate device, the Habib EUS RFA 6700 was initially cleared in K150029. The minor modifications to the device in K161305 were determined by the agency to not raise new issues of safety and effectiveness.
The Habib EUS RFA 6700 device described in both cleared 510(k) submissions have the same intended use, function and fundamental technology as the ANET Applicator.
A comparison table, Table 5-2, is included below, which illustrates the equivalence of the subject ANET device to the Habib EUS RFA 6700 device.

## Table 5-2: Comparison of Key Characteristics of Proposed Device to Predicate Device
{6}------------------------------------------------
{7}------------------------------------------------
*The proposed ANET Electrosurgical Applicator is operated in bipolar rather than monopolar mode as compared to the predicate.
The intended use of the subject device is virtually identical to that of the predicate device. In addition, the fundamental scientific technology, principle of operation and mechanism of action are similar enough to be considered substantially equivalent. Bench testing per the FDA Guidance Document, Premarket Notification (510(k)) Submissions for Electrosurgical Devices for General Surgery, indicates equivalence in performance.
Both devices use electrical energy to generate high-frequency (RF) energy as a means to coaqulate tissue. In addition, both devices consist of an electrode for coaqulation, user interface (handpiece) and connector/cable to the generator. And both devices are provided sterile, intended for single use only.
Although the predicate device is monopolar and the proposed device bipolar, we believe that RF experience supports that bipolar RF ablation is more controllable. As such, it is considered as safe if not safer than monopolar RF ablation, which also requires external grounding pads.
The Habib EUS RFA is designed to be used with a compatible, already cleared radiofrequency generator, same as the ANET Electrosurgical Applicator.
## Performance Data
Performance testing has been completed to demonstrate substantial equivalence of the subject device to the predicate device. The ANET Applicator was subjected to the following verification and validation tests, as applicable:
## Biocompatibility
Biocompatibility verification was performed for patient-contacting components of the ANET Applicator in accordance with ISO 10993-1 requirements, as well as the Guidance Document
{8}------------------------------------------------
Use of International Standard ISO-10993, "Biological Evaluation of Medical Devices Part 1: Evaluation and Testing within a Risk Management Process," June 2016.
#### Sterilization/Shelf-Life
ANET was validated to achieve a sterility assurance level of 10 ° and adopted into a validated EO sterilization cycle. Packaging validation was performed to ensure that the devices maintain package integrity and sterility.
#### Electrical Safety and Electromagnetic Compatibility (EMC)
Electrical safety and EMC testing was completed for the applicable components of the ANET Applicator. The results demonstrated compliance of the ANET Applicator to all applicable standard requirements.
#### Performance Testing
#### Mechanical and Functional Testing
Mechanical and Functional testing was completed to confirm that the performance of the ANET device conforms to the pre-determined mechanical, functional and packaging specifications at baseline and 6 months accelerated aging. Devices tested at baseline were post-sterilization (T=0), and devices tested at 6-months (T=0.5) included devices that had been subjected to both sterilization and accelerated aging.
#### Comparative Bench-Top Validation Testing to Predicate
Direct comparative bench top validation testing was completed to demonstrate the substantially equivalent ablation performance of the subject device and the predicate in various tissue types. The results demonstrated that the lesion dimensions achieved by the ANET Applicator are equivalent to those obtained with the predicate device under the same test conditions and specified power levels.
