Resectoscope and Laser Resectoscope Working Elements are intended to be used in urological procedures to endoscopically remove, cut, coagulate, and/or transect tissue in the bladder, prostate, and/or urethra. The surgeon performs the examination through the urethra. The working elements are devices that house and control the various electrodes and lasers used to remove, cut, coagulate, and transect tissue. The doctor controls the back and forth movement of the electrode using finger controls. The working elements also house a cystoscope for visualization. The high frequency cable transmits electrical current.
Albarran deflectors are intended for use in urological procedures to control the flexible instrumentation that is passed through the COMEG cystoscope sheaths.
Urethrotomes are intended to be used in urological procedures to endoscopically cut and or transect tissue(strictures) in the urethra. The surgeon performs this function through the urethra and will visually (cystoscope) find the location of the stricture in the urethra. Once the stricture is located a urethrotome knife will be extended an the entire urethrotome will be extracted cutting the affected area.
Electrodes are intended to be used endoscopically im conjunction with COMEG resectoscopes, urethrotomes, or cystoscope sheaths. The purpose of the electrodes is for cutting, tissue removal, tissue vaporization, coagulation, and/or transection of tissue. Electrodes are connected to either a resectoscope working element or a high frequency cable. The electrodes are reusable.
The COMEG devices that we intend to market include the following endoscopic electrosurgical instruments and accessories: resectoscope and laser-resectoscope working elements; Albarran deflectors; urethrotomes (urethrotome bridges, obturators, and knives); high frequency cable; and, electrodes. A "Quick-Connection" feature is used to attach the device to the sheath or working element.
Endoscopic electrosurgical instruments and accessories are described in endoscope and accessories 21 CFR 8876.1500, urethrotomes are described in 21 CFR §876.4770, and endoscope ESU unit and accessories are described in 21 CFR §876.4300.

The provided document is a 510(k) summary for COMEG Endoscopy Resectoscope and Laser-Resectoscope Working Elements, Albarran Deflectors, Urethrotomes, and Electrodes. This document focuses on demonstrating substantial equivalence to legally marketed predicate devices, not on proving device performance against specific acceptance criteria through a clinical study.
Therefore, the document does not contain the information requested in your prompt regarding acceptance criteria, study details, sample sizes, expert qualifications, adjudication methods, MRMC studies, standalone performance, or ground truth establishment.
Instead, the document primarily focuses on:
- Device Description: What the devices are and their components.
- Intended Use: The medical procedures and purposes for which the devices are designed.
- Comparison of Technical Characteristics: A statement that the subject devices are similar to predicate devices (Karl Storz and Circon ACMI) in terms of intended uses, materials, operational principles, and mode of action.
The FDA's review and approval letter (K971881) confirms that the device is "substantially equivalent" to predicate devices, which is the standard for 510(k) clearance. This process typically relies on demonstrating that the new device has the same intended use and similar technological characteristics as a predicate device, or that any differences do not raise new questions of safety and effectiveness. It does not usually require new clinical studies with detailed safety and effectiveness acceptance criteria if substantial equivalence can be demonstrated through other means (e.g., comparison to existing devices, bench testing, non-clinical performance data).

Dear Mr. Duffy
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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). You may, therefore, subject to the general controls provisions of the Act. 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.
If your device is classified (see above) into either class II (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic OS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under Radiation Control provisions, or other Federal laws or regulations.
This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in yitr diagnostic devices), please contact the Office of Compliance at (301) 594-4613. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639.
