Indications for Use
Electrodes are part of a resectoscope system for endoscopic diagnosis and treatment in urological applications. Cutting, ablation, resection, vaporization and coagulation with HF current. Electrodes are part of a resectoscope system for endoscopic diagnosis and treatment in gynecological applications. The general indications include transcervical resection, vaporization, ablation, cutting and coagulation of tissue in the uterus in nonconducting irrigation fluid. Transcervical diagnosis and treatment (resection, vaporization, ablation, biopsy, cutting and coagulation) of intrauterine myomas, intrauterine polyps, synechias and endometrium. Lysis of intrauterine septa. Endometrial ablation.
Device Story
Resection electrodes are single-use accessories for resectoscope systems used in urology and gynecology. Devices consist of an active distal tip (loops, bands, rollers, needles, or buttons), PTFE color-coded identification, insulator, guiding tube, and shaft. Operated by physicians in clinical settings; electrodes connect to an electrosurgical generator to deliver HF current for tissue cutting, ablation, vaporization, and coagulation. Monopolar versions require a separate neutral electrode; saline-application versions incorporate the return electrode into the device. Output is controlled by the surgeon via the resectoscope system to perform tissue resection or ablation. Benefits include precise endoscopic tissue management. Devices are supplied sterile via EtO sterilization.
Clinical Evidence
No clinical or animal studies were conducted. Substantial equivalence is supported by bench testing, including mechanical and electrical performance, resection/coagulation efficacy, durability, and packaging integrity. Biocompatibility was verified per ISO 10993-1. Electrical safety and EMC compliance were demonstrated per AAMI/ANSI ES 60601-1, IEC 60601-2-2, and IEC 60601-2-18.
Technological Characteristics
Active tip (loop, band, roller, needle, button), PTFE insulator, guiding tube, and shaft. Materials tested per ISO 10993-1. Energy source: HF electrosurgical generator. Sterilization: EtO (ISO 11135). Packaging: AAMI ANSI ISO 11607-1. Connectivity: None (mechanical accessory).
Indications for Use
Indicated for urological and gynecological endoscopic diagnosis and treatment. Used for cutting, ablation, resection, vaporization, and coagulation of tissue using HF current. Specific gynecological indications include treatment of intrauterine myomas, polyps, synechias, endometrium, lysis of intrauterine septa, and endometrial ablation.

# 4. Product Description
The Olympus Resection Electrodes that are subject to this submission are either monopolar or for application in saline. The main difference between monopolar electrosurgery and electrosurgery in saline is that while in monopolar electrosurgery a neutral electrode is required, whereas in electrosurgery in saline the (neutral) return electrode is part of the surgical device.
Depending on the characteristics of electrical current, which is provided by the electrosurgical generator, electrosurgery can be used for coagulation, vaporisation and cutting.
The subject HF-Resection Electrodes consist of an active tip, PTFE color code identification, an insulator between the electrode and electrode tube, a guiding tube, telescope clip and arm (shaft).
The design and dimensions of the electrodes vary to accommodate various procedural conditions. The active tips of the various electrodes may consist of loops, bands, rollers, needles or buttons.

## 6. Comparison of Technological characteristics
At a high level, the subject and predicate devices are based on similar technological principles with similar elements:
- . Resection electrodes consisting of an active (distal) tip, PTFE color code identification at the distal and proximal ends, an insulator between the electrode and electrode tube, a stabilizing (guiding) tube, and arm (shaft)
- Used in combination with a resectoscope system
- I Like the predicate electrodes, the subject device resection electrode series features loops, bands, needles, rollers, and a button as active tip shapes
- . Utilizing either monopolar mode of ablation or for resection in saline (dependent on model)
- Respectively identical or similar outer dimensions
- . Design changes of the electrodes are minor and do not negatively impact safety or effectiveness of the subject devices
- . The same or similar materials in patient contact are used in predicate and subject device and have all been successfully tested for biocompatibility.
As stated above, the subject and predicate devices have similar design characteristics and performance specifications. The primary technological differences between the subject and predicate devices are related to the patient contacting materials. These minor differences, however, do not raise different questions of safety or effectiveness. As demonstrated in the non-clinical testing (e.g., biocompatibility), the different technological characteristics do not affect the safety and effectiveness of the subject devices.

# 7. Performance Data
The following performance data was provided in support of the substantial equivalence determination. All standards applied are FDA recognized international standards.
## Biocompatibility testing
All biocompatibility testing has been conducted according to ISO 10993-1 Biological Evaluation of Medical Devices-Part 1: Evaluation and Testing. Additionally, the FDA guidance "Use of International Standard ISO-10993, 'Biological Evaluation of Medical Devices Part 1: Evaluation and Testing'' was followed.
Testing included the following tests:
- Cytotoxicity -
- Irritation -
- Sensitization -
- Chemical Analysis -
- Biological-toxicological evaluation -
## Electrical safety and electromagnetic compatibility (EMC)
Electrical Safety was tested according to
| AAMI/ANSI ES 60601-<br>1:2005 + A1:2012, C1:2009<br>and A2:2010 | Medical Electrical Equipment - Part 1.1 General<br>requirements for safety and essential performance. |
|------------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| AAMI/ANSI/IEC 60601-2-2<br>2009 | Medical Electrical Equipment - Part 2-2: Particular<br>Requirements for the Basic Safety And Essential<br>Performance of High Frequency Surgical Equipment<br>and High Frequency Surgical Accessories |
| IEC 60601-2-18:2009 | Medical electrical equipment - Part 2-18: Medical<br>Electrical Equipment - Part 2-18: Particular<br>requirements for the basic safety and essential<br>performance of endoscopic equipment. |
Electromagnetic compatibility (EMC) testing according to IEC 60601-1-2 and IEC 60601-2-2 was conducted for the resectoscope system, but not for the standalone Resection Electrodes. EMC testing demonstrates that the compatible resectoscope system complies with all requirements of IEC 60601-1-2 and IEC 60601-2-2. Since all resection electrodes are made of similar conductive materials, there is no reason to expect that different electrodes would affect the electrical properties of the resectoscope system. They do not contain
